The purpose of this application, under Articles 23.9.3, 75.5 and 81.1 of the Code, is to conserve the much-used specific name Boccardia proboscidea Hartman, 1940 for a widely dispersed mudworm (family spionidae) from California. It is proposed that the name Boccardia proboscidea be given precedence over its rarely used senior subjective synonym Polydora californica Treadwell, 1914, and that previous type fixations for Boccardia proboscidea Hartman, 1940 be set aside and one specimen be designated as neotype for this species. It is also proposed that an untypified name Spio californica Fewkes, 1889 be suppressed to avoid unnecessary confusion.

The purpose of this application, under Articles 29 and 55 of the Code, is to remove the homonymy between the earwig family-group name palicinae Burr, 1910 (Dermaptera, spongiphoridae) and the crustacean family-group name palicidae Bouvier, 1898 (Crustacea, Decapoda, Brachyura). It is proposed that the spelling of the family-group name palicinae (based on the generic name Palex Burr, 1910) be emended to give palexinae, while leaving the crustacean name palicidae (based on the type genus name Palicus Philippi, 1838) unaltered.

The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used specific name Lamprocoris lateralis (Guérin-Méneville, 1838) for a species of jewel bug from Java by suppressing its objective senior synonym Lamprocoris obtusus (Westwood, 1837). The senior name L. obtusus has never been positively treated as different from L. lateralis but has been neglected in the literature, thereby justifying conservation of Lamprocoris lateralis.

The purpose of this application, under Article 81 of the Code, is to conserve the usage of the generic names Eumolpus Weber, 1801, Chrysochus Chevrolat in Dejean, 1836 and Bromius Chevrolat in Dejean, 1836 by suppressing the name Eumolpus Kugelann in Illiger, 1798. Eumolpus Kugelann in Illiger, 1798 in its original usage included European species currently assigned to different genera, while in its modern usage Eumolpus includes mostly Neotropical species and is almost universally used in the sense of Weber (1801). It is proposed that the original usage of the name Eumolpus by Kugelann in Illiger (1798) and all usages of the name before that by Weber (1801) be suppressed. The name Eumolpus subsequently used by Weber (1801) will then become a name in its own right taking Weber's authorship thereby maintaining stability and eliminating confusion caused by potential use of Eumolpus Kugelann in Illiger, 1798.

The purpose of this case, under Articles 75.5 and 81.2.3 of the Code, is to eliminate current nomenclatural confusion within the butterfly genus Callophrys Billberg, 1820. Differing identifications of the lectotype of Callophrys dumetorum Boisduval, 1852 have changed the usages of C. dumetorum, C. viridis Edwards, 1862 and C. perplexa Barnes & Benjamin, 1923. A neotype of Callophrys dumetorum is proposed to restore these names to their previous stable usages. Moreover, the recently suggested conspecificity of C. viridis and C. sheridanii Edwards, 1877 will frequently synonymise sheridanii, a widespread, common and well known species, so it is also proposed that the widely used name sheridanii be given precedence over viridis whenever the two are considered to be synonyms.

The purpose of this application, under Articles 23.9.3 and 81.2.3 of the Code, is to conserve the specific name Megaselia abdita Schmitz, 1959 for a widespread Holarctic scuttle fly by giving it precedence over its senior subjective synonym Megaselia griseipennis (Santos Abreu, 1921), which has long been treated as a nomen dubium. A growing literature exists using the name M. abdita. It is proposed that the name Megaselia abdita be given precedence over Megaselia griseipennis (Santos Abreu, 1921) to avoid confusion.

The Commission has conserved usage of the specific name of Macrobrachium rosenbergii (De Man, 1879) by setting aside all previous type fixations and designating a neotype for the nominal species Palaemon rosenbergii De Man, 1879.

The Commission has ruled that the application for the proposed conservation of the green lacewing generic name Dichochrysa Yang, 1991 (a replacement name for Navasius X.-k. Yang & C.-k. Yang, 1990) by making the name Navasius eumorphus Yang & Yang, 1990 available, is not approved. The priority of the generic name Pseudomallada Tsukaguchi,1995 (type species: Chrysopa cognatella Okamoto, 1914, by original designation) is maintained.

The Commission has ruled that the application for the proposed conservation of the name of the Triassic amphibian genus Buettneria Case, 1922 by suppression of the names Buettneria Karsch, 1889, for a genus of extant orthopteran insects, and Buettneria Simroth, 1888, for a genus of African land snails, is not approved.

The specific name Anolis chrysolepis Duméril & Bibron, 1837 is conserved for a polytypic species of lizard that is geographically widespread in northern South America. The name was threatened by the name Draconura nitens Wagler, 1830 currently used as a senior synonym of Anolis chrysolepis Duméril & Bibron, 1837. The Commission has given precedence to the name Anolis chrysolepis Duméril & Bibron, 1837, over the name Draconura nitens Wagler, 1830, whenever the two are considered to be synonyms.
