Abstract

The marine malacofauna of New Caledonia is among the most studied and best known of the Indo-Pacific region. Previous studies have shown that its richness and species compositions are examples of extreme spatial heterogeneity. Turrids are among the richest and most diverse groups of marine gastropods. In the present paper the shallow-water turrid fauna of Ile des Pins is inventoried for the first time. 174 morphotypes hosted in 8 families are herein recorded, of which 22 species are considered new records for New Caledonia. The following new combinations were introduced: Mitromorpha drivasi (Chang, 1995), Acrista nana (Hervier, 1896), Acrista latirella (Melvill & Standen, 1896), Acrista pusilla (Dunker, 1871), Acrista tuberculifera (Hervier, 1896), Hemilienardia idiomorpha (Hervier, 1897), Heterocithara diatula (Hervier, 1897), Heterocithara isophanes (Hervier, 1897), and Pseudorhaphitoma hervieri Hedley, 1922.

INTRODUCTION

The turrids (s.l.), consist of a set of families previously classified in the family Turridae (Powell, 1966). Following a large phylogenetic study, Puillandre et al. (2011) assigned species of this family into 13 distinct families. Despite this improvement in higher level taxonomy, a considerable proportion of turrids have never been authoritatively reported since their original description. As a result, many species have never been assigned to modern genera.

In addition to the taxonomic problems, almost nothing is known about regional diversity of turrids and the differences in faunal assemblages of different regions. An exception might be New Caledonia (including the Loyalty Islands), which is the type locality of many turrid species and which has witnessed a number of incomparable marine sampling expeditions performed by the MNHN to Koumac, Touho, and Lifou. Based on these expeditions, a total of 504 turrid morphotypes were recorded, of which 231 were identified to species level (Bouchet in Payri & Richer de Forges, 2007). A study of recently published taxonomic literature demonstrated that at least 25 additional species have been described subsequently from New Caledonia (Fedosov & Puillandre, 2012; Kilburn et al., 2014; Morassi et al., 2017; Fedosov et al., 2017; Kantor et al., 2017; Fedosov & Puillandre, 2020).

A comparison of the turrid species composition of these three sites has revealed a very high level of heterogeneity between sites, with only 21% of species overlap (Philippe Bouchet, unpublished pers. communication). Since the previously sampled areas are in the northern part of New Caledonia (Koumac and Touho) and the Loyalty Islands, the aim of the present paper is the documentation of the shallow-water turrid fauna of the southernmost part of New Caledonia, the Isle des Pins.

MATERIALS AND METHODS

Sand grit was collected in preferential spots such as overhangs, caves and tunnels where specimens tend to accumulate. Sampled material was washed in fresh water, dried in thin mesh bags and sieved into different fractions (<1 mm, 1-2.5 mm, 2.5-5 mm, 5 mm-1 cm and >1 cm). Approximately 20 kg of material was collected at Ile des Pins, among which half (the fractions larger than 5 mm and smaller than 1 mm) were sorted on site. Remaining material was sorted mostly under a dissecting microscope at MHNG. When needed, the specimens have been cleaned with mounted needles and/or ultrasonic apparatus. The seldomly live collected specimens were preserved in 90% ethanol.

All dives were oraganized through the Kunié Diving resort at regular dive localities. Due to poor weather conditions, sites were determined by vessel operators based on their accessibility, and therefore were limited to the most protected and closest dive spots from the resort harbour. All diving stations data (dates, collector names, minimum and maximum depth, precise GPS positions, habitats and eventual additional notes) were consistently recorded.

A six day collection trip in February 2019 sampled 11 stations across 8 sites ranging from a depth of 0.5-27 m. See Annex 1 for stations map and Annex 2 for stations GPS positions.

Specimen images were captured through a Canon 90D with an MP-E 65 mm 1-5x lens mounted on a stack shot rail. Raw images were then stacked with Zerene stacker and final editing was completed in GIMP.

Specimen identifications were based on original descriptions, comparisons with type material, or with well documented specimen vouchers. Type material specimens, type pictures or voucher specimens were obtained from MNHN, MHNBx, ANSP, NHMUK, AMS, NSMT, and from the late Dr Richard Kilburn. Each specimen was directly compared with illustrated morphotypes from an unpublished catalogue of samplings from Koumac, Touho and Lifou (unpublished data, MNHN), in order to complete the southern New Caledonian faunal list presented here.

The classification of conoideans adapted by Bouchet et al. (2011) is followed. Generic assignments were generally followed from accepted opinions in WoRMS (2022), in a few cases, the introduction of new combination was necessary. Plates are arranged by species morphology with similar characteristics prevailing over alphabetic order.

The qualifier “aff.”, meaning “species affinis” is used for morphospecies that are clearly distinguishable but close to known taxa. The appendix “cf.” meaning “confer” is used in cases where morphospecies might be conspecific with known species but some doubts remain. If obsolete geographical names and measure units are given in the type locality, modern references are provided in square brackets “[ ]”.

RESULTS

In total, 2252 turrid specimens (or identifiable parts of specimens) were segregated into 174 morphotypes in 8 families. With 72 species, the family Raphitomidae was found to be the most diverse, while Pseudomelatomidae was the least diverse turrid family with only a single recorded species.

From those 174 morphotypes, 102 were recognized as described species, 35 were only assigned to genus level and are presumed to be new to science while the other 37 remaining morphotypes are similar to described species but are too poor in quality or represented by too few specimens to be sure. 46 morphotypes were represented by only a single specimen and 34 by two specimens, respectively, demonstrating that our sampling is far away from saturation, and that rare species make up an important part of the local turrid diversity. In contrast, Anarithma metula (though, it might represent a species complex) was represented by a total of 218 specimens. Microdaphne morrisoni and Heterocithara strombillum, secondarily were represented by more than 150 specimens each and were found at all stations sampled.

A comparison of the morphotypes found at Ile des Pins with those collected during the expeditions to Touho, Koumac and Lifou (MNHN unpublished catalogue of the New Caledonian turrid morphotypes), revealed that a total of 28 morphotypes were exclusively collected at Ile des Pins. However, since 6 species out of these 28 morphotypes were originally described from New Caledonia, 22 species are considered new records for New Caledonia. An additional 21 species would require a close examination and comparison to specimens collected at the other sites in order to confirm whether they are conspecific or not.

In the following list most morphotypes identified to genus level only have a number after “sp.” These numbers do not refer a numbering of unidentified morphotypes found in the present work, but to an unpublished, temporary numbering system of all species used by the authors in their research. Additionally, specimens demarcated with proceeding letters indicate strong affinities to the numerical destinctions.

    Plate 4, fig. 44

  • Columbella sublachryma Hervier, 1900.

  • Type locality: Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp3, idp3.2, idp5, idp5.2, idp6, idp7.

  • Remarks: This morphotype was not recorded in the unpublished MNHN catalogue of morphotypes, but was originally described from Lifou, therefore it is not considered new to New Caledonia.

  • Mitromorpha cf. sublachryma (Hervier, 1900) morph 1
    Plate 4, fig. 45

  • Type locality: Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp2, idp3.2, idp4, idp5, idp5.2, idp6, idp7, idp8.

  • Remarks: The present species differs from typical Anarithma sublachryma (Hervier, 1900) by the less developed axial sculpture, the two spiral grooves per whorl (compared to one in Anarithma sublachryma), by the two pinkish cords on the upper suture and grooves, and by the large brown dorsal blotch on the final whorl.

  • Mitromorpha cf. sublachryma (Hervier, 1900) morph 2
    Plate 4, fig. 46

  • Type locality: Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp2, idp3.2, idp4, idp5, idp5.2, idp6, idp7, idp8.

  • Remarks: The present morphotype differs from the typical Anarithma sublachryma (Hervier, 1900) by the faint axial sculpture, the almost smooth surface of the shell and by the more elongated and less biconical profile. This morphotype was not recorded in the unpublished MNHN catalogue of morphotypes.

  • Mitromorpha cf. sublachryma (Hervier, 1900) morph 3
    Plate 4, fig. 47

  • Type locality: Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp2, idp3.2, idp4, idp5, idp5.2, idp6, idp7, idp8.

  • Remarks: The present morphotype differs from Anarithma sublachryma (Hervier, 1900) in being much more stout, with shorter whorls, relatively deeper spiral grooves, resulting in a rugose shell surface similar to that of A. metula (Hinds, 1843). This morphotype was not recorded in the unpublished MNHN catalogue of morphotypes.

  • Mitromorpha aff. thalaoides Chino & Stahlschmidt, 2014
    Plate 5, fig. 53

  • Mitromorpha thalaoides Chino & Stahlschmidt, 2014.

  • Type locality: Baie du Santal, WSW of Pointe d'Easo, Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp5, idp8.

  • Remarks: The present morphotype differs from Mitromorpha thalaoides Chino & Stahlschmidt, 2014 by the ovate shape (instead of biconic), the larger adult size, the more numerous and finer knobs, and the completely different coloration.

  • Mitromorpha sp. 3

  • Genus Acrista Hedley, 1922

  • Type species: Lienardia punctilla Hedley, 1922 accepted as Acrista punctilla (Hedley, 1922) (type by original designation). Type locality: 5 to 8 fathoms [9-15 m], Murray Island, Queensland, Australia.

  • Remarks: Described as a subgenus of Lienardia, we consider it a full genus being more similar to Etrema but differing in the trigonal aperture, the sculpture of axial ribs crossed by prominent spiral cords, forming compressed nodules, and the outer lip by having only a few but larger teeth.

  • Acrista nana (Hervier, 1896) n. comb.
    Plate 5, fig. 59

  • Glyphostoma comptum var. nana Hervier, 1896a.

  • Type locality: Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp6.

  • Remarks: The freshly collected specimen in this study has brownish-orange colored grooves between the intersection of the spiral cords and faintly between the ribs, features absent in the type material. It is assumed that the type species are specimens that lost the coloration since all other morphological characters agree well.

  • Even though Pleurotoma compta Reeve, 1845 is a typical Lienadia, the present subspecies is more indicative of Acrista as defined herein.

  • This morphotype was not recorded in the unpublished MNHN catalogue of morphotypes, but was described from the Loyalty Island, therefore is not new to New Caledonia.

  • Acrista latirella (Melvill & Standen, 1896) n. comb.
    Plate 5, fig. 57

  • Mangilia (Glyphostoma) latirella Melvill & Standen, 1896.

  • Type locality: Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp2, idp3, idp3.2, idp5, idp5.2, idp6, idp8.

  • Remarks: This morphotype was not recorded in the unpublished MNHN catalogue of morphotypes, but was described from Loyalty Island, therefore is not new to New Caledonia.

  • Acrista pusilla (Dunker, 1871) n. comb.
    Plate 5, fig. 56

  • Clathurella pusilla G. Dunker, 1871.

  • Type locality: Viti Islands [Fiji].

  • Material examined: New Caledonia, Ile des Pins: st. idp2, idp3, idp4, idp5, idp6, idp7.

  • Remarks: is very similar to Glyphostoma trigonostomum Hervier, 1896b

  • Acrista tuberculifera (Hervier, 1896) n. comb.
    Plate 5, fig. 58

  • Glyphostoma marchei var. tuberculifera Hervier, 1896a.

  • Type locality: Lifou, New Caledonia.

  • Material examined: New Caledonia, Ile des Pins: st. idp3.2.

  • Remarks: Our single specimen agrees well with the type specimen of Glyphostoma marchei var. tuberculifera Hervier, 1896 (syntype MNHN-IM-2000-30091). However, we have strong doubts about the validity of the presumed type specimens since they are not even remotely simililar to the type of Lienardia marchei Jousseaume, 1884 (syntype MNHN-IM-2000-3082). Given that the existent types of Glyphostoma marchei var. tuberculifera are instead much closer to Glyphostoma disconica Hervier (1896) (syntype MNHN-IM-2000-2904), described in the same publication, is a further hint of a possible confusion of the type specimens. Unfortunately, an original figure of the Glyphostoma marchei var. tuberculifera type is missing and the meagreness of the orginal description is of little help. However, the resolving this dilemma is beyond the scope of the present paper but could be of interest to future workers.

  • Genus Clathurella Carpenter, 1857

  • Type species: Clavatula rava Hinds, 1843 accepted as Clathurella rava (Hinds, 1843) (type by subsequent designation). Type locality: 18 fm [33 m], Gulf of Nicoya, Central America.

  • Etrema cf. crassilabrum (Reeve, 1843)
    Plate 6, fig. 76

  • Pleurotoma crassilabrum Reeve, 1843.

  • Type locality: Ticao Island, Philippines.

  • Material examined: New Caledonia, Ile des Pins: st. idp1.

  • Remarks: The present species is very similar to Etrema crassilabrum (Reeve, 1843) but differs slightly in the weaker spiral sculpture and the less developed denticles in the columella. However, the single available specimen is subadult and a comparison of adult specimens with the type or topotypic specimens is required to provide confirmation.

  • Etrema aff. crassilabrum (Reeve, 1843)
    Plate 6, fig. 75

  • Material examined: New Caledonia, Ile des Pins: st. idp3.2.

  • Remarks: The present species differs from Etrema crassilabrum (Reeve, 1843) in the denser and weaker axial sculpture as well as in a different colouration.

  • Etrema cf. glabriplicatum (Sowerby III, 1913)
    Plate 6, fig. 77

  • Glyphostoma glabriplicatum G. B. Sowerby III, 1913.

  • Type locality: Osumi, Japan.

  • Material examined: New Caledonia, Ile des Pins: st. idp2, idp4.

  • Remarks: The present species is similar to Etrema glabriplicatum (Sowerby III, 1913) but differs in the stouter profile, brown coloration below periphery on later teleoconch whorls and the denser axial sculpture.

  • Etrema cf. polydesma Hedley, 1922
    Plate 6, fig. 73

  • Etrema polydesma Hedley, 1922.

  • Type locality: 15 fm. [27 m], Palm Islands, Queensland, Australia.

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp3.2, idp5.2, idp8.

  • Remarks: The present species appears to be conspecific with Etrema polydesma Hedley, 1922, but differs slightly in the colouration and sculpture. A comparison with the type or fresh topotypic specimens is required to provide confirmation.

  • Etrema sp. 1a
    Plate 6, fig. 70

  • Material examined: New Caledonia, Ile des Pins: st. idp2, idp3.2, idp5.2, idp7.

  • Remarks: The present species is remotely related to Etrema polydesma Hedley, 1922, but differs in the less angulated whorls.

  • Etrema sp. 1b
    Plate 6, fig. 71

  • Material examined: New Caledonia, Ile des Pins: st. idp1.

  • Remarks: The present species might be conspecific with Etrema sp.1 but differs slightly in the colouration and sculpture. More specimens are required to examine if the differences are stable or just within the intraspecific variation.

  • Etrema sp. 1c
    Plate 6, fig. 72

  • Material examined: New Caledonia, Ile des Pins: st. idp6.

  • Remarks: The present species is also similar to Etrema sp.1 but differs in the more angulated whorls and the rougher axial and spiral sculpture.

  • Etrema sp. 5
    Plate 6, fig. 78

  • Material examined: New Caledonia, Ile des Pins: st. idp6.

  • Remarks: The present species is only known by a single subadult specimens, but differs in sculpture and colour pattern from all other species reported here.

  • Etrema sp. 6
    Plate 6, fig. 74

  • Material examined: New Caledonia, Ile des Pins: st. idp4.

  • Remarks: The present species is known from one subadult specimen and is remotely similar to Etrema crassilabrum but differs in the less angulated whorls and different colour pattern.

  • Genus Lienardia Jousseaume, 1883

  • Lienardia aff. vultuosa (Reeve, 1845)
    Plate 6, fig. 69

  • Pleurotoma vultuosa Reeve, 1845.

  • Type locality: Baclayon, Bohol Island, Philippines.

  • Material examined: New Caledonia, Ile des Pins: st. idp4.

  • Remarks: The present morphotype is similar to Lienardia vultuosa (Reeve, 1845) but differs in having a stouter shell profile and fewer denticles in the interior of the outer lip. The specimens analysed here appear to belong to the Lienardia vultuosa-leucostigmatarhodacme species-complex. A detailed study is needed to establish limits of either interspecific or intraspecific variation based on coloration, sculpture and lip dentation.

  • Lienardia sp. 1
    Plate 6, fig. 61

  • Material examined: New Caledonia, Ile des Pins: st. idp1, idp6.

  • Remarks: Specimens collected and analysed in this study were not recorded in the MNHN unpublished catalogue of morphotypes.

  • Lienardia sp. 2

  • Material examined: New Caledonia, Ile des Pins: st. idp3.2.

  • Remarks: This morphotype was not recorded in the MNHN catalogue of morphotypes.

  • Genus Nannodiella Dall, 1919

  • Type species: Philbertia (Nannodiella) nana Dall, 1919 accepted as Nannodiella nana (Dall, 1919) (type by original designation). Type locality: 26 fm [48 m], off Cacachitas, Gulf of California.

  • Remarks: The following two species are only provisionally placed in Nannodiella due to the similar shell shapes and the spout-like anal sinus, characters that may prove to be artificial. The type species of the genus Nannodiella, Philbertia (Nannodiella) nana Dall 1919, an east pacific species, lacks the apertural denticles which are well developed in N. acricula and N. cf. tortilabia.

  • Nannodiella acricula (Hedley, 1922)
    Plate 5, fig. 54

  • Etrema acricula Hedley, 1922.

  • Nannodiella cf. tortilabia (Hedley, 1922)
    Plate 5, fig. 55

  • Etrema tortilabia Hedley, 1922.

  • Type locality: 5-8 fm. [9-15 m], off Murray Island, Queensland, Australia.

  • Material examined: New Caledonia, Isle des Pins: st. idp1, idp2, idp3, idp3.2, idp4, idp5, idp5.2, idp6, idp7, idp8.

  • Remarks: The present morphotype appears to be Nannodiella tortilabia (Hedley, 1922). However, the type of the latter species is of poor quality and the figure by Hedley (1922) only illustrated a specimen with a much more acute apex, further complicating the identification of the morphotype. Verification of specimens from the type locality, or nearby, is necessary to confirm the true identity of this specimen.

  • Remarks: We follow Fedosov & Puillandre (2012) by using the genus Exomilus for the following two species, even though the type of Exomilus is a temperate species and probably not related to the species listed here, while some of the species currently placed in Kermia or Pseudodaphnella appear to be closer. However, the delimitation of these complicated genera needs molecular methods and is beyond the scope of the present paper. The use of Exomilus is utilized for the reason of consistency.

  • Material examined: New Caledonia, Ile des Pins: st. idp5.2.

  • Remarks: There is a group of very similar species, morphologically comprising of Hemilienardia gemmulata, H. fenestrata (Melvill, 1898), and H. hersilia (Hedley, 1922), that appear to be different species. The present morphotype appears to differ slightly from Hemilienardia gemmulata in the larger size, more shouldered whorls, and denser sculpture. Molecular studies are required for a resolution to this species complex.

  • Material examined: New Caledonia, Ile des Pins: st. idp2, idp5.2.

  • Remarks: This morphotype was not recorded in the unpublished MNHN catalogue of morphotypes, but was described from Lifou, and therefore is not new to New Caledonia.

  • Pseudodaphnella cf. barnardi (Brazier, 1876)
    Plate 9, fig. 110

  • Clathurella barnardi Brazier, 1876.

  • Type locality: Barnard Island, north east Australia [Queensland].

  • Material examined: New Caledonia, Ile des Pins: st. idp2.

  • DISCUSSION

    While the number of morphotypes observed during this mission seems relatively low compared to the average number of morphospecies reported in the three sites surveyed by the MNHN (approximately 280 species per site), this richness is considered remarkable when taking into account the limited sampling effort and range of the habitats surveyed. Typical expeditions performed by the MHNH average approximately 500 workdays across all participants for the duration of the mission, compared to a much smaller effort (8 workdays in the field) in the current study. Moreover, only a small portion of the north-western region of Ile des Pins was sampled, with all stations but one within a 4.6 km2 proximity. Furthermore, the range of habitats sampled was limited to outer reefs and passages while fringing reefs, intermediate reefs, sea grass beds and other soft bottom habitats where unexplored. In perspective, the area sampled by the Montrouzier expeditions, estimated at 350 km2 at Touho and Koumac (Bouchet, 1994), covered a full range of available habitats. Therefore, it is assumed that a comparable sampling effort at Ile des Pins would very likely result in many additional morphotypes.
