The purpose of this application, under Article 23.9.5 of the Code, is to conserve the name Murex rostratus Olivi, 1792 (currently Fusinus rostratus) (Mollusca, Gastropoda, fasciolariidae) in its prevailing usage by ruling that this name is not invalid by virtue of being a junior primary homonym of Murex rostratus Solander in Brander, 1766 (currently Turricula rostrata). The senior homonym is currently included in turridae and has not been considered congeneric with Murex rostratus Olivi, 1792 after 1899.

The purpose of this application, under Article 81.1 of the Code, is to conserve the current usage of the widely used name Malmgrenia McIntosh, 1874 (a polynoid worm genus from the northern North Atlantic) by designation of Malmgrenia andreapolis McIntosh, 1874 as the type species of Malmgrenia. The type species of Malmgrenia is at present Malmgrenia whiteavesii McIntosh, 1874, which is virtually a nomen nudum. The type material of Malmgrenia whiteavesii McIntosh, 1874 has been lost and no other specimens referable to this species have been recorded. It is proposed that Malmgrenia andreapolis McIntosh, 1874 be designated as the type species of Malmgrenia to maintain the current usage of this generic name.

The purpose of this application, under Article 75.5 of the Code, is to conserve the usage of the name Scleropauropus Silvestri, 1902 for a group of pauropods (Myriapoda, Pauropoda) while also conserving as its type species the nominal species S. hastifer Silvestri, 1902, by replacing with the same neotype the unsuitable holotypes of both S. hastifer Silvestri, 1902 (type species by monotypy), and S. lyrifer Remy, 1936 (consistently, but erroneously treated as the type species of Scleropauropus since Remy (1957)).

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the usage of the name charilaidae Dirsh, 1953 for a group of African grasshoppers. The name is threatened by a little used senior name pamphagodidae I. Bolivar, 1916. The name charilaidae Dirsh, 1953 has become widely accepted and is in prevailing usage. It is proposed that the name charilaidae Dirsh, 1953 be given precedence over pamphagodidae I. Bolivar, 1916.

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the usage of the family-group name pseudococcini Cockerell, 1905 (type genus Pseudococcus Westwood, 1840) for the mealybugs, a speciose group including many pests of agriculture, by giving it precedence over the senior family-group name sphaerococcini Cockerell, 1899 (type genus Sphaerococcus Maskell, 1892).

The purpose of this application, under Article 70.2 of the Code, is to conserve the current usage of the widely used name Helops Fabricius, 1775 for a genus of tenebrionid beetles from Western Palaearctic, Nearctic and Neotropical Regions by designation of Tenebrio caeruleus Linnaeus, 1758 as the type species. The type species of Helops Fabricius, 1775 is at present Tenebrio lanipes Linnaeus, 1771 (currently Stenomax lanipes). The use of the original designation would seriously affect the nomenclatural stability of long-recognized generic and subtribal concepts in the tribe helopini. It is proposed that all type fixations for the nominal genus Helops Fabricius, 1775 before that of Tenebrio caeruleus Linnaeus, 1758 by Hope (1840) be set aside.

The purpose of this application, under 23.9.3 of the Code, is to conserve the generic names Pedionomus Gould, [1 December] 1840 for the Australian plains-wanderer (pedionomidae) and Leipoa Gould, [1 December] 1840 and the specific name Leipoa ocellata Gould, [1 December 1840] for the Australian malleefowl (megapodiidae). The names Pedionomus Gould, [1 December] 1840, Leipoa Gould, [1 December] 1840 and Leipoa ocellata Gould, [1 December] 1840 have been in prevailing usage as the valid names for these taxa for over 150 years. However, Gould on 31 October, 1840 used the name Pedionomus ocellatus for the malleefowl, and this name has been used as valid for the malleefowl on at least one occasion in the 20th century. Suppression of Pedionomus ocellatus Gould, [31 October] 1840 will maintain stability in nomenclature.

The purpose of this application, under Articles 24.2 and 81.2.3 of the Code, is to conserve the usage of nine specific names of Australian birds. The names, chosen as senior by First Revisers, were later replaced almost a hundred years ago by simultaneously published names on grounds of page precedence. The names chosen by page precedence, all of common and often popular Australian birds, have been in prevailing use ever since and are in universal use today. This application seeks to validate these names for reasons of nomenclatural stability.

The purpose of this application, under Article 23.9.3 of the Code, is the conservation of the generic name Atrichornis Stejneger, 1885 for the Australian scrub-birds (atrichornithidae), which has been in universal use as a valid generic name for almost 90 years. It is threatened, through the incorrect subsequent spelling Atrichia, by the name Atricha Gould, 1844, which was used for the scrub-birds into the first decade or so of the 20th century, and thus cannot be replaced under Article 23.9.2 of the Code. It is proposed that the name Atricha Gould be suppressed to confer stability in nomenclature.

The Commission has ruled that the usage of the name Obovaria Rafinesque, 1819 is conserved for a freshwater bivalve from the eastern United States by designation of Unio retusa Lamarck, 1819 as the type species and that the name Obovaria obovalis Rafinesque, 1820 is a nomen oblitum.

An application to conserve the generic name Oncopus Thorell, 1876 for a group of nine opilionids from Southeast Asia, together with the family-group name oncopodidae Thorell, 1876 for geometrid moths from Asia, by suppressing the little used senior homonym Oncopus Herrich-Schäffer, 1855 for two South American Lepidoptera has not been approved.

The Commission has ruled that all previous type species fixations for the nominal genus Tydeus Koch, 1836 are set aside and Tydeus spathulatus Oudemans, 1928 is designated as the type species.

The Commission has ruled that the type material of the scorpion Cercophonius brachycentrus bivittatus Thorell, 1877 (currently Orobothriurus bivittatus) from Argentina should not be replaced by a neotype. The original material still exists and there is no exceptional need to designate a neotype.

The Commission has ruled that the specific name Ceutorhynchus contractus (Marsham, 1802) is conserved for a well known species of European weevil (family curculionidae) by suppression of a little used senior primary homonym Curculio contractus Geoffroy in Fourcroy, 1785.

The Commission has ruled that the specific name Celaenorrhinus ratna Fruhstorfer, 1908 is conserved for a widespread tropical butterfly (hesperiidae) by suppression of Notocrypta kawakamii (currently Celaenorrhinus kawakamii) Matsumura, 1907.

The Commission has ruled that the current usage of the name Schizechinus Pomel, 1869 (Echinodermata, Echinoidea) for a genus of toxopneustid echinoids from the Miocene of the Mediterranean region and possibly the Neogene of Australia is not conserved. The name Echinus serresii Des Moulins, 1837 is maintained and designation of Psammechinus serresii Desor, 1856 as the type species of Schizechinus Pomel, 1869 is not accepted.

The Commission has ruled that the original spelling Hyloxalus panamansis Dunn, 1933 should be maintained for the specific name of a Central American dendrobatid frog. The subsequent spelling Hyloxalus panamensis Dunn, 1940 is not conserved.

The Commission has ruled that the current usage of the generic name Calamaria H. Boie in F. Boie, 1827 for a genus of Asian colubrid snakes is conserved by setting aside all previous fixations of type species and designating Calamaria linnaei H. Boie in F. Boie, 1827 as the type species.
