The purpose of this application, under Article 23.9.3 of the Code, is to conserve the usage of the name Bagauda Bergroth, 1903 (type species Bagauda avidus Bergroth, 1903) for a genus of thread-legged assassin bug from Afrotropical and Oriental Regions, by giving it precedence over the senior generic name Pleias Kirkaldy, 1901 (type species Pleias ritsemae Kirkaldy, 1901).

The purpose of this application, under Article 29 of the Code, is to conserve the names aulacoscelini Chapuis, 1874 and aulacoscelinae Chapuis, 1874 first used by Monrós (1949 and 1953, respectively) for Aulacoscélites Chapius, 1874 for a group of Coleoptera currently placed in the orsodacnidae Thomson, 1859 (traditionally they have been placed in the chrysomelidae Latreille, 1802). There are two spellings currently used for this group of beetles, aulacoscelinae and aulacoscelidinae. Although aulacoscelidinae appears to be grammatically correct, aulacoscelinae has been in prevailing usage for the last 55 years and was in sole use for 37 years, from 1953 to 1990. The fact that both spellings are currently in use is undesirable, promoting instability.

The purpose of this application, under Article 75 of the Code, is to conserve the usage of the specific name of the staphylinid Xantholinus gracilis Sperk, 1835 (currently Scopaeus gracilis). The holotype of Xantholinus gracilis is lost and the originally published characters differ from those of Scopaeus gracilis as currently understood. It is proposed that a neotype that is in accord with the current use of the name be designated.

The purpose of this application, under Article 69 of the Code, is to conserve the usage of the generic name Tentyria Latreille, 1802 by designation of Tentyria ligurica Solier, 1835 as the type species of this genus of darkling beetles from the Palaearctic region. A series of previous nomenclatural acts resulted in the designation of Pimelia orbiculata Fabricius, 1775 as the type species of both Tentyria Latreille, 1802 and Tentyrina Reitter, 1900 making Tentyrina Reitter, 1900 an objective junior synonym of Tentyria Latreille, 1802. It is proposed that all previous fixations of type species of Tentyria Latreille, 1802 be set aside and Tentyria ligurica Solier, 1835 be designated as the type species.

The purpose of this application, under Articles 29 and 55.3, is to remove the homonymy between the family-group name corystidae Foster & Philip, 1978 (Echinodermata, Echinoidea) and corystidae Samouelle, 1819 (Crustacea, Brachyura). corystidae Samouelle, 1819 and corystidae Foster & Philip, 1978 are homonyms resulting from similarity of the names of their type genera, Corystes Bosc, 1802 and Corystus Pomel, 1883, respectively. Both names are in use. It is proposed to change the spelling of the echinoderm family-group name to corystusidae by emending the stem of the name of the type genus Corystus Pomel, 1883, while leaving the crustacean name, based on Corystes Bosc, 1802, unchanged.

The purpose of this application, under Article 33.2.3 of the Code, is to rule that the spelling of the name Raja say Le Sueur, 1817 (currently Dasyatis say) of bluntnose stingray be changed to Raja sayi Le Sueur, 1817 to follow Müller & Henle's (1841) unjustified emendation. The spelling Raja sayi Le Sueur, 1817 is in prevailing usage, and therefore could be conserved under Article 33.2.3.1 of the Code, but the exact meaning of ‘prevailing usage’ as it formulated in Article 33.2.3.1 is not sufficiently clear, allowing for subjectivity. It is proposed that the spelling be changed to sayi to ensure stability and future uniformity of use.

The purpose of this application, under Article 81.1 of the Code, is to avert ongoing nomenclatural confusion by suppression of the ambiguous and untypified binomen Columba norfolciensis Latham, 1801, which has been applied to three different species in different columbid genera within the last hundred years.

The purpose of this application, under Articles 33.2.3 and 33.3 of the Code, is to rule that the name of the Black-browed Albatross Diomedea melanophris Temminck, 1828 (currently Thalassarche melanophris) is confirmed as the correct original spelling. Since 1839, half of authors have used melanophris and the other half melanophrys, following Temminck's (1839) incorrect subsequent spelling. The difference is not statistically significant, and it is proposed that the original spelling is confirmed as correct to follow the priority and to promote stability.

The Commission has ruled that the current usage of the specific name egmontianum for a common and widespread western Atlantic bivalve Trachycardium egmontianum (Shuttleworth, 1856) of the family cardiidae is conserved by setting aside all lectotype designations for Cardium mindanense Reeve, 1844 prior to that by Vidal (1998).

The Commission has ruled that the spelling and current usage of the generic name Phyllomorpha Laporte, 1833 is conserved. The generic name has been used consistently for a genus of coreidid heteropterans found in Southern Europe, North Africa and the western part of Asia to Pakistan, although it is an incorrect spelling of the generic name Phyllomorphus Laporte 1833. Coreus hystrix Latreille 1817 is designated as the type species, with all fixations of type species before Reuter (1888) set aside.

The Commission has ruled that the current usage of the generic name Bothynus Hope, 1837 for well-known scarab beetles of the family scarabaeidae (subfamily dynastinae) is conserved by the designation of Scarabaeus ascanius Kirby, 1819 as the type species. The original type species of Bothynus was Geotrupes cuniculus Fabricius, 1801, but was based on a misidentification. The designation of S. ascanius Kirby, 1819 as the type species was proposed by Lacordaire in 1856, but, although this was adopted by most taxonomists, this was not valid under the Code.

The Commission has ruled that the specific name Onthophagus sycophanta Fairmaire, 1887 for a dung beetle found throughout Vietnam and China is conserved by suppressing its senior primary homonym Onthophagus sycophanta Mulsant, 1842.

An application to conserve the specific name Productus compressus Waagen, 1884 for the type species of the Permian brachiopod genus Compressoproductus Sarytcheva in Sarytcheva et al., 1960 by suppression of Productus compressus Say in James, 1823 has not been approved.
