The purpose of this application, under Article 23.9.3 of the Code, is to conserve the specific name Geophilus bonensis Meinert, 1870 for a species of geophilomorph centipede, currently classified in the genus Gnathoribautia Brölemann, 1909. G. bonensis is universally considered the valid name for this species after 1963 and it has often been used in past and recent literature; however it is threatened by the long forgotten subjective synonym Necrophloeophagus punctiventris Newport, 1844, which has been completely disregarded as a valid name since 1880.

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used specific name Elasmucha dorsalis (Jakovlev, 1876) for a species of subsocial acanthosomatid bug from East Asia. The name is threatened by the senior subjective synonym Elasmucha vicina (Uhler, 1861), which has seldom been used since its first publication. Therefore, precedence of the name Elasmucha dorsalis (Jakovlev, 1876) is proposed.

The purpose of this application, under Article 23.9.5 of the Code, is to conserve the specific names Cerambyx striatus Goeze, 1777 and Cerambyx striatus Fabricius, 1787. Cerambyx striatus Linnaeus, 1758, C. striatus Goeze, 1777 and C. striatus Fabricius, 1787 are primary homonyms, but the first name has never been congeneric with either of the other two because it was transferred to Callidium Fabricius, 1775 two years before the description of the first junior primary homonym. The other two nominal species have not been considered congeneric since 1817, when Fabricius's species was transferred to Trachyderes Dalman, 1817. Finally, C. striatus Goeze was removed from Cerambyx Linnaeus, 1758 and placed in Dorcadion Dalman, 1817 in 1947. Currently, Cerambyx has no species with the specific name striatus and the three primary homonyms are in use in distinct generic combinations and are placed in three different subfamilies of cerambycidae. It is proposed that the names Cerambyx striatus Goeze, 1777 and C. striatus Fabricius, 1787 be conserved by ruling that they are not invalid by reason of being junior primary homonyms of C. striatus Linnaeus, 1758.

The purpose of this application, under Article 81.1 of the Code, is to conserve the genus-group names Liancalus Loew, 1857 and Scellus Loew, 1857 (Diptera, dolichopodidae), widely distributed and well-established genera of dolichopodid flies whose names have been used consistently for more than one-and-ahalf centuries. They are threatened by a change in the type species of Anoplomerus Rondani, 1856, made in a largely-overlooked unpaginated corrigendum on the last page of Rondani (1856). Liancalus Loew, 1857 is a replacement name for the homonym Anoplomerus and automatically takes its type species. It is proposed that Liancalus Loew, 1857 and Scellus Loew, 1857 be conserved by designating Dolichopus regius Fabricius, 1805 as type species for Anoplomerus Rondani, 1856 under the Commission's plenary power. This solution will protect both names and serve to promote nomenclatural stability.

The purpose of this application, under Article 75.6 of the Code, is to designate a new neotype for the mangrove monitor Varanus indicus (Daudin, 1802), which is endemic to the Moluccan islands of Indonesia. The recent choice of an unrepresentative specimen to serve as neotype for this nominal species has resulted in a shift of the specific name to a different species of Varanus, V. chlorostigma (Gray, 1831) from New Guinea and surrounding islands, and the recognition of an unnecessary taxon, V. cerambonensis Philipp, Bohme & Zeigler, 1999, on Ambon, Seram and Buru in the Moluccas. To conserve the name indicus in its original usage and to avoid further taxonomic confusion, it is proposed that the current neotype specimen be replaced by a new one that belongs to the original taxonomic species involved, thereby reducing V. cerambonensis to a junior subjective synonym of V. indicus and also conserving V. chlorostigma in its accustomed use as the valid name for the New Guinean species.

The Case is brought under Articles 78.1, 81.1 and 89 of the Code to resolve a controversy surrounding the stem of family-group names based on Ortalis Merrem, 1786, a genus of large, pheasant-like birds (chachalacas) of the New World. This genus has a junior homonym in Diptera, Ortalis Fallén, 1810, and various family-group names based on the dipteran genus were proposed before anyone noticed the homonymy. Despite their invalidity under Article 39 of the Code, these dipteran names remain available names, preoccupying obvious stems for avian family-group names. A new tribe ortalidaini Donegan, 2012 was proposed for the avian Ortalis, its non-standard stem Ortalida- being chosen under Article 29.6 of the Code to avoid homonymy with dipteran names. Subsequently, an attempt was made to emend ortalidaini to ortalisini David, 2014, but the emended name is identical in spelling to the available dipteran name ortalisini Acloque, 1897. Acceptance of ortalidaini as the valid spelling might be threatened as a result of the differing English and French versions of Article 29.3.3 of the Code concerning family-name stem formation, the French preventing an otherwise valid emendation of this name, but the English not. The Commission is asked to choose between (i) endorsing ortalidaini Donegan, 2012 as being based on an ‘appropriate’ stem under Article 29.6; or (ii) using its plenary power to suppress ortalisini Acloque 1897 in favour of David (2014)‘s junior homonym ortalisini, giving precedence to the English version of Article 29.3.3 of the Code and deeming David (2014)’s emendation to be valid on different grounds to those stated (i.e. ortalidaini being inappropriate under Article 29.6); or (iii) suppressing all competing family-group names based on Ortalis Fallén, 1810 and making the ‘standard’ family-group name ortalidini thereby capable of usage in Aves.

The Commission has ruled under Articles 78.2.3 and 80.2.1 that the wording of Article 1.3.2 be interpreted to confirm the availability of Cornu Born, 1778 for a genus of land snails (family helicidae), that was based on a teratological specimen of Helix aspersa Müller, 1774.

The Commission has declined to fix the neotype of Helix papillaris Müller, 1774 as neotype for Turbo bidens Linnaeus, 1758. As a result, Turbo bidens is not a senior synonym of Helix papillaris (currently Papillifera papillaris). Instead the neotype for Turbo bidens designated by Kadolsky (2009) is allowed to stand.

The Commission has conserved the prevailing usage of the generic name Ecdyonurus Eaton, 1868 and the specific name Ecdyonurus venosus (Fabricius, 1775), by setting aside the existing name-bearing type of Ecdyonurus venosus and designating a neotype.

The Commission has not used its plenary power to conserve the name Dibolia schillingii (Letzner, 1847) for a flea-beetle species (chrysomelidae, alticinae; or galerucinae, alticini) widespread in western Palaearctic, by giving it precedence over the unused older name Dibolia metallica (Motschulsky, 1845), whenever these names are considered to be synonyms.

The Commission has not approved the request to rule under its plenary power on the status of several generic names in the lycaenidae. Instead, under Articles 78.2.3 and 81.2.4 of the Code, the Commission, using its specific powers, confirms the availability of all the new generic names proposed in d'Abrera (2001) and consequently the availability of any replacement names proposed for any of them.

The Commission has conserved the specific name Heteropsis narcissus (Fabricius, 1798), despite being a junior homonym of Hypochrysops narcissus (Fabricius, 1775). Both names are currently in use to designate separate and well-recognized species, belonging to two distinct genera in two butterfly families from different geographic regions.

Under the plenary power, the Commission has conserved the usage of the generic name Coenosia Meigen, 1826, for a well-established genus of muscid flies. All type fixations for Coenosia Meigen, 1826 prior to that of Musca tigrina Fabricius, 1775 by Westwood (1840) have been set aside. Also under the plenary power, the family-group name coenosiinae Verrall, 1888 has been given precedence over limosiinae Robineau-Desvoidy, 1830 whenever the two are placed in the same family-group taxon.

Under the plenary power the Commission conserved the usage of the name Anchisaurus Marsh, 1885 (Lower Jurassic, Connecticut Valley, northeastern U.S.A.) that is based on Megadactylus polyzelus Hitchcock, 1865. The fragmentary and non-diagnostic holotype of M. polyzelus has been replaced with a diagnostic neotype, an almost complete skull and skeleton (YPM1883, holotype of A. colurus Marsh, 1891).
