The purpose of this application, under Article 23.9.3 of the Code, is to conserve the specific name of the well-known species Cantharidus capillaceus (Philippi, 1849), a common marine gastropod from southern New Zealand and Macquarie Island. The name is threatened by the senior subjective synonym Trochus episcopus Hombron & Jacquinot, 1848 which has been mentioned very rarely since its first publication. Precedence of the name Trochus capillaceusPhilippi, 1849 over Trochus episcopus Hombron & Jacquinot, 1848 is proposed.

The purpose of this application, under Article 23.9.5 of the Code, is to conserve the specific names Scarabaeus ferrugineusOlivier, 1789 (currently Metacatharsius ferrugineus) (Scarabaeidae) and Scarabaeus ferrugineusPalisot de Beauvois, 1809 (currently Bradycinetulus ferrugineus) (Geotrupidae). Although Scarabaeus ferrugineusOlivier, 1789 and Scarabaeus ferrugineusPalisot de Beauvois, 1809 are primary homonyms, they have not been treated as congeneric for almost 180 years and were both transferred out of the genus Scarabaeus Linnaeus, 1758 by 1845. Both names have been treated as valid since they were proposed. It is proposed that Scarabaeus ferrugineusPalisot de Beauvois, 1809 be conserved by ruling that it is not invalid by reason of being a junior homonym of Scarabaeus ferrugineusOlivier, 1789.

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the specific name Bolitophagus cornutusFabricius, 1801 (currently Bolitotherus cornutus) for a common and well-known North American darkling beetle by giving it precedence over its senior synonym Opatrum bifurcumFabricius, 1798.

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used specific name Metochus abbreviatus Scott, 1874, for a species of rhyparochromid bugs from East Asia. The name is threatened by the senior subjective synonym Rhyparochromus erosusWalker, 1872, which has seldom been used since its first publication. Therefore, precedence of the name Metochus abbreviatus Scott, 1874 over Rhyparochromus erosusWalker, 1872 is proposed.

The purpose of this application, under Article 19.2, is to conserve the widely used specific name Lema decempunctataGebler, 1829. In the original publication, the printed name clearly reads “L. ropunctata”. Nearly all subsequent taxonomists have interpreted this spelling as an error of the typesetter and have used the epithet decempunctata instead. Therefore, the Commission is requested to rule under the plenary power that decempunctata should be regarded the original spelling with Gebler, 1829 as the original author.

The purpose of this application, under Article 81.1 of the Code, is to conserve the widely used binomen Quetzalcoatlus northropi in its accustomed usage by making the generic and specific names available and attributing authorship to Lawson (1975b).

The purpose of this application, under Article 81 of the Code, is to conserve the accustomed usage of the name Thamnophilus schistaceus d'Orbigny, 1838, for an antshrike confusingly treated in the works that dealt with the findings of d'Orbigny during his travels in southern South America almost 200 years ago. The name has been almost wholly consistently used since its introduction, but is now potentially threatened by evidence revealed during bibliographic research.

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used name Gymnetis marmorea (Olivier, 1789), a flower chafer (Scarabaeidae: Cetoniinae) from Trinidad and Tobago, West Indies, which is threatened by the unused senior subjective synonym Scarabaeus pulcherSwederus, 1787. The head of the holotype of Scarabaeus pulcherSwederus, 1787 is excluded from the holotype under Article 73.1.5 of the Code since it is a piece belonging to a Cotinis Burmeister glued to the body of a Gymnetis MacLeay.

Under the plenary power the International Commission on Zoological Nomenclature has ruled to set aside all previous type fixations for Belostoma ellipticum Latreille, 1817, and to designate as neotype a specimen that conserves current usage of the specific name.

The purpose of this application is to conserve usage of the name Adelgidae Schouteden, 1909 for a family of conifer-feeding insects, some species of which are important forestry pests. Although it has nomenclatural priority, Pineini Nüsslin, 1909 is alternately considered a subordinate taxon to or a synonym of Adelgidae. Meanwhile, Chermaphidinae Hunter, 1901, a disused name treated as a synonym of Adelgidae or Pineini, has nomenclatural priority over both. In accordance with Article 23.9.3, the present application requests a ruling under the plenary power described in Article 81.2.3 to conditionally suppress Chermaphid- and Pine- with respect to Adelg-.

The purpose of this application, under Articles 78.1, 80.2. and 81.1 of the Code, is to conserve the in-use spellings leucorynchusLinnaeus, 1771 and mascarinusLinnaeus, 1771 as respective justified emendations of the specific names for the woodswallow, Artamus leucorynchus (Linnaeus, 1771), type species of the avian genus Artamus (Artamidae), and the parrot, Mascarinus mascarinus (Linnaeus, 1771), type species of the avian genus Mascarinus (Psittacidae). In an Appendix for animal species in his Mantissa Plantarum Altera (1771), Linnaeus originally published these names as “mascarin.” and “leucoryn.” in the binomina Lanius leucoryn. and Psittacus mascarin., with punctuation marks. Because of punctuation, they have been treated as abbreviated and spelled out almost universally since the late 18^th century. Their spelling-out is now being challenged by reinterpretation and reintroduction of mascarin and leucoryn as unabbreviated. Evidence from the formatting and punctuation of species names in the Mantissa Plantarum Altera is presented to show that leucoryn. and mascarin. are, in fact, abbreviated; and the ruling of Official Correction 82 of the Commission in an associated case is cited in support. In the interests of nomenclatural stability, and to accord with the ruling of Official Correction 82, it is proposed that leucoryn.Linnaeus, 1771 and mascarin.Linnaeus, 1771 be determined as incorrect original spellings, and that all spelling-outs of leucoryn. and mascarin. other than leucorynchus and mascarinus respectively be ruled as unjustified emendations. An appended table lists all 20 punctuated animal names in the Mantissa Plantarum Altera, recording those that are abbreviated and those that are not, and identifying the nominal species to which they apply today.

The purpose of this application, under Article 75.6 of the Code, is to conserve the specific name Digitonthophagus gazella (Fabricius, 1787) for a common African species of dung beetle (also known as Onthophagus gazella) that was successfully introduced into multiple areas all over the world. The species is of high economic importance as it is used as a biological control agent of pest flies and provides ecological services through the rapid burial of cattle dung. Scarabaeus gazella Fabricius, 1787 is a junior synonym of Scarabaeus catta Fabricius, 1787, now known as Digitonthophagus catta. If the principle of priority is applied, the name of the widely distributed species, would be Scarabaeus dorcasOlivier, 1789, a name that has been considered a junior synonym of Scarabaeus gazella/Scarabaeus catta since 1833. We propose to conserve the name Digitonthophagus gazella (Fabricius, 1787) for the widely introduced species through the designation of a neotype from voucher material of the original introduction into Hawaii. All feedback received from colleagues was supportive for the proposed designation of a neotype in order to maintain prevailing usage of the name D. gazella.

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widespread usage of the generic name CharissaCurtis, 1826 by suppression of its senior subjective synonym Hyposcotis Hübner, [1825] for promotion of stability and universality of zoological nomenclature.

The purpose of this application, made under Article 23.9.3 of the Code, is to conserve the family-group name Sphenopidae Hertwig, 1882 that is in widespread and current usage for a group that includes ecologically, medically and toxicologically important species. Sphenopidae Hertwig, 1882 is threatened by Palythoidae Duchassaing de Fombressin & Michelotti, 1860, which has only been used once as a valid name since 1899.

The purpose of this application, under Article 75.5 of the Code, is to set aside all type fixations for the crocodyliform Allodaposuchus precedensNopcsa, 1928, and to designate a neotype. The type series of A. precedens includes specimens from the Maastrichtian (Late Cretaceous) of Vălioara, housed at the Magyar Állami Földtani Intézet (Hungarian Geological Institute) in Budapest, Hungary. The original material includes several cranial and postcranial elements thought to correspond to the same specimen but the attribution of this set of remains as belonging to one individual cannot be confirmed. Therefore, subsequent papers considered only part of this set, a fragmentary skull table, as the lectotype of A.precedens. Given the recent description of several species closely related to A. precedens and the lack of a combination of exclusive characters that can diagnose the species based on the specimens studied by Nopcsa, we request that the Commission set aside all previous type fixations and designate a neotype for A. precedens. The neotype designation is of utmost importance for the objective identification of this species, which is necessary for future phylogenetic analyses and assessments of crocodyliform diversity.

The purpose of this application, under Articles 70.2 and 80 of the Code, is to conserve the current and universal usage of the genus name HeteronychusDejean, 1833 for a genus of rhinoceros beetles (Scarabaeidae: Dynastinae). Several species in this genus are important pests in Africa, Asia and Australia. The correct, long-overlooked type species is Geotrupes syrichtusFabricius, 1775, designated by Duponchel (1845), is currently recognized as a valid species and the type species of Syrictes Prell, 1935, a genus placed in a different tribe of Dynastinae. Acceptance of this type species would transfer a widely used name from an economically important to a rarely cited genus, and the economically important genus would need to be named by the scarcely used subjective junior synonym HeteronychidiusPaulian, 1954 with a dubious taxonomic identity. To conserve the usage of the widely used name Heteronychus, it is proposed that all type fixations for this genus preceding that of Heteronychus cricetusHausmann, 1807 by Krell (2002) be set aside.

The International Commission on Zoological Nomenclature has used its plenary power to conserve the generic name PhrynusLamarck, 1801 (Arachnida, Amblypygi, Phrynidae) by suppressing TarantulaFabricius, 1793, and Phrynus operculatusPocock, 1902 has been designated as its type species. These and several other names have been placed on the relevant Official Lists and Indexes.

The International Commission on Zoological Nomenclature has used its plenary power to resolve the homonymy between the family names Photinini LeConte, 1881 for a group of lightning bugs and Photininae Giglio-Tos, 1915 for a group of praying mantises by ruling that the stem of the generic name PhotinaBurmeister, 1838 for purposes of Article 29 of the Code is Photina-, thereby emending the mantis subfamily name to Photinainae Giglio-Tos, 1915. The Commission has further ruled under the plenary power that Photinus pallensFabricius, 1798 is both a justified emendation of P. pullensFabricius, 1798 and the type species of PhotinusLaporte, 1833, and that Mantis vitreaBurmeister, 1838 is available despite being a junior primary homonym of M. vitreaStoll, 1813.

The International Commission on Zoological Nomenclature has used its plenary power to conserve the generic name NesocyrtosomaMarcuzzi, 1976 by ruling that it is available from its original proposal despite its not having been accompanied by a type species fixation. The Commission has also designated Cyrtosoma inflatumMarcuzzi, 1976 as the type species of NesocyrtosomaMarcuzzi, 1976.

The International Commission on Zoological Nomenclature has declined to use its plenary power to conserve the generic name MaculineaVan Eecke, 1915 in its accustomed usage. As a result the generic name PhengarisDoherty, 1891 has priority over MaculineaVan Eecke, 1915 whenever the two are considered to be synonyms.

The International Commission on Zoological Nomenclature has declined to use its plenary power to remove the homonymy between the earwig family-group name Palicinae Burr, 1910 (Dermaptera, Spongiphoridae) and the crustacean family-group name Palicidae Bouvier, 1898 (Crustacea, Decapoda, Brachyura) by changing the stem of the former name's type genus. Under Articles 40.2 and 60.2 of the Code, Platylabiinae Burr, 1911 is recognized as the currently valid name of this dermapteran subfamily.

The International Commission on Zoological Nomenclature has used its plenary power to designate Anaphes fuscipennisHaliday, 1833 as the type species of the generic name of parasitic wasps AnaphesHaliday, 1833.

The International Commission on Zoological Nomenclature has declined to use its plenary power to set aside the existing holotype of Basilosaurus kochiiReichenbach, 1847 (currently Zygorhiza kochii) and designate a neotype.

The International Commission on Zoological Nomenclature has not used its plenary power to conserve the generic name KalophrynusTschudi, 1838 by setting aside all previous designations and designating a neotype for its type species KalophrynuspleurostigmaTschudi, 1838.

The International Commission on Zoological Nomenclature has declined to use its plenary power to conserve the specific name Dysactis pallida Agassiz in Verrill, 1864 for a species of sea anemone.

The trilobite genus BrachypleuraAngelin, 1854 (type species Remopleuridessexlineatus, Angelin, 1851) is a homonym of BrachypleuraGünther, 1862 applied to a species of flounder, and has priority over the latter. The holotype of the type species of Brachypleura is well preserved and was figured by Nikolaisen (1983). BrachypleuraAngelin, 1854 is not synonymous with the trilobite genus AmphitryonHawle & Corda, 1847. SculptaspisNikolaisen, 1983 is a junior subjective synonym of BrachypleuraAngelin, 1854. The details of the publications by Nils Peter Angelin (1851–52, 1854, 1878) are discussed in detail.
