The type species of the goblin spider genus Triaeris Simon, T. stenaspis Simon, was originally described from Saint Vincent in the Lesser Antilles, but has attained a pantropical distribution and even has introduced populations living in European greenhouses. At least one of those European populations is parthenogenetic, and no males of the species have ever been found. Simon later assigned one additional species to the genus, T. equestris, from Principe; that species is also known only from females, but resembles T. stenaspis in having an unusually elongated, ventrally spinose patella on leg I. Numerous other species, from both the Old and New worlds, have subsequently been assigned to Triaeris; all those taxa seem to be either synonyms (including T. berlandi Lawrence from the Democratic Republic of the Congo, T. lepus Suman from Hawaii, and T. lacandonus Brignoli from Guatemala, which are newly synonymized with T. stenaspis) or misplaced in the genus. The modified patella I occurs in four new West African species (T. moca from Bioko and T. fako, T. oku, and T. menchum from Cameroon); unfortunately, those species are also represented only by females. Few other gamasomorphines have patellar spines, and most of those that do have such spines belong to a group of genera in which the males have heavily sclerotized endites, suggesting that Triaeris might belong to that group. Searching West African collections of such taxa revealed two additional new species, T. togo and T. ibadan, that are each represented by both sexes. Female genitalic structure suggests that T. togo is the closest relative of T. stenaspis.
INTRODUCTION
The goblin spider genus Triaeris Simon (1891) has been an enigma wrapped around a mystery. It was initially described for Triaeris stenaspis Simon (1891), which was based on females from St. Vincent in the Lesser Antilles, and which Simon had also collected in Venezuela. Within a few years, additional specimens were found in the greenhouses of the Muséum National d'Histoire Naturelle in Paris (Simon, 1896), and also in greenhouses in Ireland (Jackson, 1909; O. P.-Cambridge, 1909). Today, numerous greenhouse populations of the species appear to be well established in various European countries, including Finland (Koponen, 1997) and Germany (Kielhorn, 2008), and a population found in Brno, Czech Republic, has been shown to be parthenogenetic (Korenko et al., 2009). It is possible that all the populations of the species are parthenogenetic, as no males appear ever to have been taken together with any of the 1,600 female specimens recorded below.
Very few spider species are known to be parthenogenetic. Only one other case has been reported in goblin spiders, where Heteroonops spinimanus (Simon) has been considered to be parthenogenetic by some authors (Saaristo, 2001). That species resembles T. stenaspis in that, even though it was originally described from St. Vincent, it currently has a pantropical distribution and has also been found in European greenhouses (Kielhorn, 2008). Although many populations of H. spinimanus may be parthenogenetic, apparently conspecific males have been taken together with females twice, once in the Seychelle Islands and once in Florida (Platnick and Dupérré, 2009b).
The female genitalia of T. stenaspis are extremely complex. The internal structures were first illustrated by Brignoli (1974: fig. 4A) and Miller and Zitnanska (1976: pl. II, fig. 6). Although Brignoli's figure was based on a female from Guatemala he described as a new species, it is almost identical to Miller and Žitňanská's illustration of a Slovakian female they correctly attributed to T. stenaspis; in both cases, those authors drew only the posterior genitalic elements. Much more detailed figures and descriptions have since been provided by Dumitresco and Georgesco (1983: pl. 19, fig. 4, pl. 20, figs. 1–3) and especially by Burger (2009: figs. 6–10, 23A–B). Our scanning electron micrographs show that even the external elements are anomalously complex (figs. 31, 32). Why a parthenogenetic species has genitalia that are so complex, if they have no copulatory or sperm storage function, remains a mystery.
Equally mysterious has been the question of whether T. stenaspis is natively an Old or New World species. Although ground-dwelling oonopids typically have very small geographic ranges (perhaps the smallest, per species, of any spider group), there are about a dozen species within the family that have anomalously managed to attain pantropical distributions. For example, two other species that were initially described by Simon (1891) from St. Vincent, Opopaea deserticola and Pelicinus marmoratus, are pantropical taxa whose New World populations are now considered to be introduced rather than native (Platnick and Dupérré, 2009a; Platnick et al., 2012b).
One should be able to answer the question by finding the closest relative of T. stenaspis, but the existing taxonomy of the genus is as problematic as is T. stenaspis itself. Currently, there are 17 other species assigned to the genus (Platnick, 2012), including both Old and New World taxa. Only one of those 17 species was described by Simon: Triaeris equestris Simon (1907), based on a single female from the island of Principe. Simons association of that species with T. stenaspis was apparently based on what he considered the most salient character of the genus, the presence of an elongated patella, bearing ventral spines, on leg I (figs. 17, 37). Simon (1893: 297) used that character to separate Triaeris in his key to gamasomorphine genera, and his account (1896: 93) of T. stenaspis stressed that “ses pattes antérieures, également armées de fines épines sériées, sont remarquables par la grande longueur de leur article patellaire.” Why most of the 16 taxa added by subsequent workers were placed in the genus is an enigma. Aside from three names placed below as synonyms of T. stenaspis, none of those taxa seem to share the patellar characters emphasized by Simon, and they all seem to be misplaced.
For example, Chickering (1968) reviewed the specimens of Triaeris in his extensive collections from Central America and the West Indies. His generic description omitted any mention of the highly modified patella I, and provided no diagnostic characters whatever for the genus. Aside from T. stenaspis, he described two new species. One, Triaeris reticulatus, from the Virgin Islands and Nevis, has been shown to be a junior synonym of Pelicinus marmoratus Simon (Platnick et al., 2012b); the other, Triaeris bodanus from Trinidad, belongs to a different genus currently being studied by Alexandre Bonaldo and his colleagues.
Workers on Old World taxa have not fared any better. Simons colleagues Berland (1914) and Fage (1946) added species from Kenya and India, respectively, but they are also misplaced (Fannes, in prep.; Grismado, in prep.). Many additional Indian species established by more recent authors are so poorly described and illustrated that one can say little about them other than they are clearly not members of Triaeris (indeed, at least one of them is probably not even an oonopid).
Triaeris has typically been considered to be a close relative of Ischnothyreus Simon (1893), sharing with that genus a somewhat reduced dorsal abdominal scutum and a characteristically “squiggled” posterior receptaculum in the female genitalia (figs. 38, 39). Indeed, Dumitresco and Georgesco (1983) even attempted to establish a subfamily containing only these two genera, but because they did not designate a type genus, and did not base the subfamily name on an existing genus, their “Pseudogamasomorphinae” is a nomen nudum that is not available.
There are characters that might support such a relationship. For example, in Ischnothyreus peltifer (Simon), the pantropical type species of that genus, the postepigastric scutum bears an external slit (D. Ubick, unpublished scans) similar to that found in T. stenaspis (figs. 31, 32), although the slit in I. peltifer is much smaller and is situated anteriorly on the scutum, rather than posteriorly. Also, in both type species the claws on legs III and IV are accompanied by “false claws”—highly modified setae on which the tips lack the microsetae found more proximally and have become hardened and clawlike (figs. 21, 22, 25, 26). The claw character, however, is also shared with other, presumably more distantly related taxa, including the Asian genus Aprusia Simon (see Grismado et al., 2011: figs. 60–66) and the Malagasy genus Malagiella Ubick and Griswold (2011: frontispiece and figs. 77, 78, 82–84).
If Triaeris is the sister group of Ischnothyreus, its geographic origins remain obscure, as Ischnothyreus also occurs in both the Old and New worlds. The vast majority of Ischnothyreus species are Old World taxa, and it is possible that, as with Opopaea and Pelicinus, all the New World populations are introduced, but that has not yet been established.
However, Simon's primary character for the genus, the modified patella I, suggests an alternative hypothesis. Very few gamasomorphine oonopids are known to have patellar spines, and most of those that do have such spines belong to a group of genera that are united by the presence of highly modified, heavily sclerotized endites in males. That group, which has been studied in detail by Wouter Fannes (in prep.), includes taxa such as Zyngoonops Benoit (1977), Coxapopha Platnick (2000), and Antoonops Fannes and Jocqué (2008). Although this alternative hypothesis seems to be supported in preliminary molecular analyses by Eva Gaublomme (in litt.), in which Triaeris typically falls out close to or within this group of genera, it is equally uninformative geographically. The taxa with heavily sclerotized male endites are known from both the Neotropics and Africa.
Nevertheless, Simons association of T. equestris with T. stenaspis suggested that other close relatives of T. stenaspis might be found in West Africa, and searches of West African collections in the California Academy of Sciences by Darrell Ubick turned up four seemingly congeneric species, one from Bioko and three from Cameroon. Each of those species shares the modified patella I, but unfortunately they are also each known only from females. Luckily, Wouter Fannes' thorough sorting of the massive African collections available in the Royal Museum for Central Africa revealed two additional species, from Togo and Nigeria, that are each represented by both sexes. The genitalia of the females of T. togo, new species, have the same kind of external, longitudinal slit, situated along the midline of the posterior portion of the postepigastric scutum, that is found in T. stenaspis (compare figs. 31 and 78), and those taxa thus seem likely to be sister species.
The males of these two new species show the highly modified, heavily sclerotized endites typical of genera in the Zyngoonops group. These results suggest that Triaeris is natively a West African genus, belonging to the Zyngoonops group, one species of which has attained a pantropical distribution. They also suggest that, if males of T. stenaspis do exist anywhere, they would likely have been sorted into other groups in collections, as males of the Zyngoonops group typically have an elevated, domed carapace with heavily sclerotized anterolateral corners, as well as the highly modified endites, and thus often look quite different from the females.
In the New World, at least one such misplaced male member of the Zyngoonops group has been described: Xestaspis reimoseri Fage (1938), taken in a termite nest in Costa Rica; Fage's excellent illustration of the modified endites shows clearly that the species does not belong to Xestaspis, but his description also indicates that this male lacks leg spines, and it is thus equally unlikely to belong to Triaeris. It presumably belongs instead to Coxapopha or a related, new genus.
Several undescribed West African species resemble those we discuss below in having an elongated, ventrally spinose patella I, but differ in genitalic and other characters. We therefore consider Simon's classical character to be a synapomorphy not of Triaeris, but rather of a subgroup of about four genera belonging to the Zyngoonops group. If our hypothesis is correct, then “Triaeris subgroup” might be an appropriate informal name for the set of genera belonging to the Zyngoonops group that also share the elongated, spinose patella I.
Thus, among the African species that have been misplaced in Triaeris, the specimens of T. equestris belong to an undescribed genus in the Triaeris subgroup, whereas those from Kenya and Zanzibar described by Berland (1914) as Triaeris macrophthalmus do not belong to the Triaeris subgroup, but do have heavily sclerotized endites and are thus members of the Zyngoonops group. At least the male of Xestaspis sertata Simon (1907) from Bioko is also apparently a member of the Zyngoonops group (but not the Triaeris subgroup). The poorly known genus Kijabe Berland (1914) from Kenya may also belong to the Zygnoonops group.
The two species described below that are known from males show a number of distinctive features. The male palpal patella bears a prolateral series of leaf-shaped setae (figs. 74, 107) that have not been detected, to date, in any other oonopids. The same is true for an enlarged seta situated subdistally on the male labium (figs. 70, 86), and a pair of enlarged setae situated anterolaterally on the male sternum (figs. 70, 89, 90, 126). As expected, at least T. ibadan shares with T. stenaspis the presence of “false claws” on the posterior legs (figs. 98, 99), and at least those two species also share a distinctive seta, on the anterior surface of each cheliceral paturon, that is greatly elongated and extends at least half the length of the paturon (figs. 4, 6, 83, 84, 110, 111).
Our methods follow those of Platnick and Dupérré (2009a); all measurements are in mm. High-resolution versions of the images, a sortable version of the geocoded locality data, and a distribution map for each species will be available on the goblin spider Planetary Biodiversity Inventory (PBI) project's website ( http://research.amnh.org/oonopidae).

Triaeris Simon
Triaeris Simon, 1891: 561 (type species by monotypy T. stenaspis Simon).
DIAGNOSIS: Members of this genus have notably elongated, ventrally spinose patellae on leg I (figs. 17, 37), a feature that is shared with a group of undescribed genera from West Africa. The males assigned below to Triaeris can easily be separated from those of the undescribed groups by several unique modifications, including the leaf-shaped setae on the palpal patella (figs. 74, 107), the enlarged, subdistal seta on the labium (figs. 70, 86), and the pair of enlarged setae near the anterolateral corners of the sternum (figs. 70, 89, 90, 126); they also differ in having a simple embolus without accessory structures (figs. 73, 105). The females assigned below to Triaeris show a wide range of genitalic structures, but differ from those of the undescribed genera in having hypertrophied posterior genitalic elements, which occupy most of the postepigastric scutal area and involve external modifications of that scutum (figs. 31, 32). The notably elongated seta found in both sexes on the anterior surface of each cheliceral paturon (figs. 4, 6, 83, 84, 110, 111) may also be unique to Triaeris.
GENDER: The gender of the name Triaeris has been controversial; Bonnet (1959), for example, regarded the name as masculine. That view was disputed by Brignoli (1974: 209), who indicated that:
Some doubt may arise concerning the genus [sic, lapsus for gender] to be attributed to the name Triaeris; in my opinion, the etymology is clear: Tris + aeris i.e. “with three parts of copper”; in practice, an apposition. Berland has taken it as masculine and has described T. macrophthalmus; according to me, by analogy with other names again created by Simon, such as Xestaspis, Anasaspis, Coryssocnemis, etc., it sounds better in the feminine (the noun aranea being understood).
Our colleague H. Don Cameron has kindly indicated that Brignoli's etymology is erroneous, reflecting an accidental similarity. Simon consistently followed a 19th-century grammar school convention to differentiate a long “e” from a short “e” by spelling the long “e” as “ae.” To distinguish the Latin words levis (“light,” short e) from lēvis (“smooth,” long e), for example, Simon spelled smooth as laevis. Thus, Triaeris is properly spelled Triēris in standard Latin (and without the macron, to accord with the Code, Trieris). Simon's original spelling of the generic name is of course protected by the Code, but the gender is determined by the correct Latin spelling. The word triēris is a two-ending Latin adjective meaning “having three banks of oars” (e.g., the spelling is triēris for masculine or feminine, triēre for neuter). Simon's type species, T. stenaspis, does not solve the problem since stenaspis is also a two-ending adjective (meaning “having a narrow carapace”). So Triaeris should be treated as masculine under ICZN Art. 30.1.4.2, which specifies masculine as the default gender in such cases.

DISTRIBUTION: Aside from the pantropical type species, the genus is known only from West Africa.
INCLUDED SPECIES: Of the various names currently assigned to Triaeris (see Platnick, 2012, for a listing), only T. stenaspis and its synonyms actually belong to the genus. Of the other African species, T. equestris (from Príncipe) belongs to a different genus in the Triaeris subgroup, whereas T. macrophthalmus (from Kenya and Zanzibar) belongs to a different genus in the Zyngoonops group. The various taxa from outside of Africa are wildly misplaced.

DIAGNOSIS: Females can easily be recognized by their complex genitalia, which occupy most of the postepigastric scutum; externally there is a median longitudinal slit (figs. 31, 32), internally there is a large, triangular posterior receptaculum with a distally squiggled duct (figs. 33, 38–40).
MALE: Unknown.
FEMALE (PBI_OON 10511, figs. 1–40): Total length 1.47. Carapace pale orange, sides finely reticulate. ALE largest, separated by their radius to diameter; posterior eye row procurved from front. Sternum, mouthparts pale orange. Dorsal scutum pale orange, covering more than 3/4 of abdomen, more than half to most of abdomen width. Postepigastric scutum pale orange, with posteriorly directed lateral apodemes represented only by wide flanges. Legs pale orange, without color pattern. Leg spination: patella I v1p-1r-1p; tibiae: I v2-4-0; II v1p-1p-0; IV v0-0-1p. Ovoid atrium present between medially invaginated edges of epigastric and postepigastric scuta, that atrium with transverse sclerotization anterior of narrower, longitudinal sclerotization; posterior receptaculum squiggled.
