The purpose of this application, under Article 81.2.1 of the Code, is to conserve the specific name of the terrestrial slug Krynickillus maculatus Kaleniczenko, 1851 (currently Limax maculatus or Limacus maculatus, limacidae) by suppression of its little-used senior homonyms Limax maculatus Nunneley, 1837 and Limax cinereus var. maculatus Picard, 1840, for the sake of nomenclatural stability and universality.

The purpose of this application, under Article 81.1 of the Code, is to conserve the name Antheraea roylei Moore, 1859 believed to be the progenitor of Bombyx (Saturnia) pernyi Guérin-Méneville, 1855 (currently Antheraea pernyi). Tussah silk is second only to mulberry silk (from Bombyx mori) in world production and consumption. Recently compiled evidence indicates that the tussah silkmoth, also called the Chinese oak silkmoth, Antheraea pernyi Guérin-Méneville, 1855, was derived thousands of years ago in China from the Himalayan Antheraea roylei Moore, 1859, which would place the latter in synonymy under the former, since the two names refer to the same biological species. Although there are no significant and consistent differences in wing pattern and genitalia, both names have had wide usage for more than 150 years, and the two entities differ in their chromosome numbers and cocoon structure. The name A. roylei has been applied by almost all authors to wild collected material in India, Burma, Nepal, Thailand, etc., while the name A. pernyi has been used by Chinese and Korean authors for sericultural populations and wild collected specimens in southern China, although the wild collected material does not differ from that of countries that share borders with southern China. The authors propose that the name Antheraea roylei be conserved and added to the Official List of Specific Names in Zoology.

The purpose of this application, under Article 81 of the Code, is to conserve the name Saturnia canningi Hutton, 1859, the progenitor of Samia ricini (Jones, 1791). The eri silk moth (Samia ricini) is the third largest source of silk in world commerce. The Himalayan Samia canningi has been demonstrated to be the wild progenitor of S. ricini, which exists only in captivity. Therefore, the two names refer to the same biological species, but the name Phalaena ricini Jones, 1791 has precedence over Saturnia canningi Hutton, 1859. However, both names have been used widely and consistently by authors in the entomological and sericultural literature for over 150 years to refer to the domesticated and wild entities, respectively. The authors propose that the name Saturnia canningi be conserved and added to the Official List of Specific Names in Zoology, so that it can continue to be used when referring to the wild form.

The purpose of this application, under Articles 78.2.3 and 80.2.1 of the Code, is to confirm that the generic name Spracklandus Hoser, 2009 [23 March] for the African spitting cobras is available in the sense of the Code, and also that the work in which this genus was proposed met the Code's criteria of publication under Article 8.1. The Commission is asked to rule on these seemingly routine matters because widely promulgated recommendations by some herpetologists to use a junior objective synonym, Afronaja Wallach, Wüster & Broadley, 2009 [21 September], instead has resulted in instability in nomenclature.

The purpose of this application, under Articles 81.1, 81.2.3.2, 23.9.3 and 33.3.1 of the Code is to (1) conserve the family name corcoracidae Mathews, 1927 for the Australian bird family known as mudnesters; and (2) conserve melanorhamphos Vieillot, 1817 as the correct spelling of the valid name for the type species of the type genus of corcoracidae. At family or subfamily rank, corcoracidae has been in prevailing use for the mudnesters for over 50 years. Reversal of precedence for the competing name struthideidae Mathews, 1924 under Article 81.2.3.2 of the Code will maintain stability in nomenclature. The species-group name melanorhamphos, an incorrect subsequent spelling of Coracia melanoramphos Vieillot, 1817, has also been in prevailing use for the type species of the type genus of corcoracidae for over 50 years. Deeming melanorhamphos as the correct original spelling under Article 81.1 and in accordance with Article 33.3.1 will also maintain stability in nomenclature.

The purpose of this application, under Articles 78.1, 80.2.2 and 81.2.2 of the Code, is to conserve current usage of the well-established genus-group name Touit G.R. Gray, 1855 for a genus of South American parrotlets by suppression of the earlier but little-used, taxonomically ambiguous name Pyrrhulopsis Reichenbach, 1850. This course of action would also help to confirm the validity of the widely used genus-group name Prosopeia Bonaparte, 1854 for the Fijian shining parrots which has also been replaced by Pyrrhulopsis at times owing to differing interpretations of its meaning.

The Commission has ruled under the plenary power that the generic name Haliplanella Hand, 1956 is conserved for a widespread sea anemone by suppressing the senior name Haliplanella Treadwell, 1943, which was first, through an error, used for a group of polychaete annelids, was later put into synonymy, and is now no longer used.

The Commission has conserved the generic name Stirpulina Stoliczka, 1870 for a group of watering-pot shells by suppression of the little-used senior subjective synonym Tubolana Bivona Bernardi, 1832.

The Commission has emended the spelling of the family-group name metinae Simon, 1894 (Arachnida, Araneae, tetragnathidae), used for a group of orb-weaving spiders and based on the generic name Meta C.L. Koch, 1835, to give metainae, thereby removing homonymy with the crustacean family-group name metidae Boeck, 1872, based on the generic name Metis Philippi, 1843.

The Commission has conserved the specific name Curculio scirpi Fabricius, 1792 (currently Notaris scirpi; curculionoidea, erirhinidae) by giving it precedence over a little-used older name C. rhamni Herbst, 1784, whenever the two are considered to be synonyms, and by suppressing the little-used senior homonym C. scirpi Rossi, 1790.

The Commission has conserved the usage of the specific names Crotalinus catenatus Rafinesque, 1818 (currently Sistrurus catenatus) and Crotalus tergeminus Say in James, 1822 (currently Sistrurus tergeminus or Sistrurus catenatus tergeminus) for two species of pygmy rattlesnake, by designation of neotypes.

Ascalaphus macleayanus Guilding, 1823 is fixed as the type species of the Western Hemisphere owlfly genus Ululodes Smith, 1900 (ascalaphidae). Information clarifying the proper authorship, date of publication and nomenclatural gender of this name is presented.

The purpose of this note, under Article 39, is to propose the replacement name boltonocostidae for the invalid name orthocostidae Bolton, 1912, a monotypic family of fossil insects (Insecta, Hypoperlida) of Carboniferous age.
