The purpose of this application, under Articles 78.2.3 and 80.2.1 of the Code, is to suggest a possible interpretation of Article 1.3.2 in relation to the availability of the generic name Cornu Born, 1778 for a genus of land snails (family helicidae). There has been longstanding confusion regarding the correct generic combination for the well-known, common and widely introduced land snail originally described as Helix aspersa Müller, 1774, that is, whether it should be placed in Cornu Born, 1778, Cantareus Risso, 1826 or Cryptomphalus Charpentier, 1837. The confusion has arisen primarily because of differing interpretations of Article 1.3.2 in relation to the original proposal of the genus-group name Cornu Born, 1778 for the species Cornu copiae Born, 1778, which was based on a teratological specimen of Helix aspersa Müller, 1774. It is proposed that the wording of Article 1.3.2 be interpreted to confirm the availability of Cornu Born, 1778.

The purpose of this application, under Article 81.1 of the Code, is to conserve the usage of the generic name Praeradiolites Douvillé, 1902 by designation of Sphaerulites ponsiana d'Archiac, 1837 as the type species. The current type species of Praeradiolites, Radiolites fleuriausus d'Orbigny, 1842, has characteristic features of Eoradiolites Douvillé, 1909 instead of Praeradiolites of current usage, and cannot be used as the objective standard of reference for the application of the name Praeradiolites. Maintaining the present situation would entail a series of disruptive taxonomic changes and threaten stability. We propose the replacement of the type species of Praeradiolites, which appears to be a less disruptive solution and may better guarantee wide acceptance and stability.

The purpose of this application, under Articles 23.9.3 and 81 of the Code, is to conserve the usage of the specific name Cryptotermes dudleyi Banks, 1918 for an important economic termite pest species introduced throughout much of the world by man. The senior name, Calotermes havilandi parasita Wasmann, 1910 (currently Cryptotermes parasita), is poorly known, not widely used, and applied only to a population of restricted distribution, while the junior name has been universally used in an extensive systematic, biological, and pest management literature since 1918 when it was first proposed. It is accordingly proposed that the specific name dudleyi be given precedence over parasita whenever the two are considered to be synonyms.

The purpose of this application, under Articles 29 and 55.3.1 of the Code, is to remove the homonymy between two family-group names, coryninae of Hymenoptera (Insecta) and corynidae of Anthoathecata (Cnidaria). It is proposed to adopt the Greek genitive form Corynid- of the sawfly genus Corynis Thunberg, 1789 as the stem of the corresponding family-group name, giving corynidinae Benson, 1938. corynidae Johnston, 1836, a name for hydrozoans, would remain unchanged.

The purpose of this application, under Article 75.5 of the Code, is to conserve the name Apis armbrusteri Zeuner, 1931 for a species of fossil honey bee occurring in the Miocene fauna of southwestern Germany. The holotype is the hollow impression of a bee from the Early Miocene Böttingen Marmor and, aside from attributing the taxon to the tribe apini, no details regarding its specific identity can be gleaned from this specimen. Nonetheless, this name has been universally applied to the Early Miocene honey bees from Böttingen Marmor and the related contemporaneous site from the same crater series, Randeck Maar, since Zeuner & Manning (1976). Although A. armbrusteri is recognised as a nomen dubium, to resurrect the unused specific epithet Apis scheuthlei (Armbruster, 1938) for these bees would be counter to current usage and would destabilise a voluminous literature on honey bee evolution and ecology. It would also threaten the subgeneric name Cascapis Engel, 1999 as A. armbrusteri sensu Zeuner & Manning (1976), i.e. based on the Randeck Maar material, is its type species by original designation. Accordingly, it is proposed that the unidentifiable holotype be set aside and one of the more exquisitely preserved and easily diagnosable specimens from this same fauna be designated as neotype, thereby stabilising the honey bee taxonomy and bringing the application of the name A. armbrusteri in line with universal current usage.

The purpose of this application, under Articles 80.9 and 81.1 of the Code, is to designate Anaphes fuscipennis Haliday, 1833 (family mymaridae) as the type species of Anaphes Haliday, 1833. The nominal species A. punctum Shaw, 1798 is currently the type species by subsequent designation and is placed on the Official List of Specific Names in Zoology, but no type specimen of A. punctum existed until Huber (2011) showed conclusively that punctum belongs to the genus Camptoptera Foerster, 1856 and designated a neotype. It is clearly unacceptable that the type species of a genus does not belong to that genus so a request to the Commission to change the type species to the only other originally included species of Anaphes, A. fuscipennis, is presented, to maintain the current usage.

The purpose of this application, under Article 81.1 of the Code, is to preserve stability in the taxonomy of stegosaurian dinosaurs by replacing Stegosaurus armatus Marsh, 1877, the unidentifiable type species of the ornithischian dinosaur genus Stegosaurus Marsh, 1877, with the very well represented nominal species Stegosaurus stenops Marsh, 1887, also from the Upper Jurassic Morrison Formation, U.S.A. This genus is the basis for Stegosauria Marsh, 1877, stegosauroidea Marsh, 1880, stegosauridae Marsh, 1880 and stegosaurinae Marsh, 1880. Maidment et al. (2008) listed seven putative autapomorphic characters for Stegosaurus and five for the species Stegosaurus armatus in its current usage. However, the holotype of S. armatus, which consists of an articulated series of 18 incomplete vertebrae from the proximal half of the tail and a very large but incomplete dermal plate, shows none of these diagnostic characters and so S. armatus must be considered a nomen dubium. However, the holotype of S. stenops Marsh, 1887 shares all 12 autapomorphies with S. armatus in its current usage, being based on an almost complete skeleton (USNM 4934), most of it still in the rock preserving almost natural articulation, which would make S. stenops by far the best available species to replace S. armatus as type species of Stegosaurus Marsh, 1877.

The Commission has conserved the name Petauristes quadripunctatus (Olivier, 1808) for a common and widespread South Asian beetle originally described as Crioceris quadripunctata, by ruling that it is not invalid by reason of being a junior primary homonym of Crioceris quadripunctata Fabricius, 1801 (currently Monolepta quadripunctata).

The Commission has ruled that homonymy between the Coleoptera family-group name nomiidae Gozis, 1875 (type genus Nomius Laporte, 1835) and Hymenoptera family-group name nomiinae Robertson, 1904 (type genus Nomia Latreille, 1804) be removed by changing the spelling of the senior name (the entire generic name of Nomius is used to form nomiusidae), while the hymenopteran family-group name (based on Nomia Latreille, 1804) remains unaltered.

The Commission has conserved the specific name of the widespread Palaearctic marsh beetle Cyphon palustris Thomson, 1855 (scirtidae), published as a junior primary homonym of Cyphon palustris Germar, 1818 (currently Eubria palustris, psephenidae) by ruling it to be not invalid by reason of being a junior primary homonym.

An application to conserve the generic name Pseudobagrus Bleeker, 1859 for a group of bagrid catfishes (order Siluriformes) by suppressing the senior name Tachysurus La Cepède, 1803, was not approved by the Commission.

The Commission has conserved the accustomed usage of the name cornutus Temminck, 1822 for the Sumatran population of the southeast Asian species currently named Batrachostomus javensis (Horsfield, 1821) (Aves, podargidae) by ruling that the name Podargus cornutus was proposed by Temminck (1822) for a new taxon, rather than as a replacement name for Podargus javensis Horsfield, 1821. The Commission has designated a neotype for Podargus cornutus Temminck, 1822.

The generic name Cuvieronius Osborn, 1923, for South American gomphotheriid proboscideans, has been conserved by setting aside all previous type species fixations and designating Mastotherium hyodon Fischer, 1814 as the type species of Cuvieronius and by designating a neotype for that species.
