Case 3450 (see comments BZN 66:3, 66:4)
Chrysophanus florus Edwards 1884 (currently Lycaena florus) (Insecta, Lepidoptera, LYCAENIDAE): conservation of the specific name by designation of a neotype for Polyommatus castro Reakirt, 1866 (currently Lycaena castro)

Abstract. The purpose of this application, under Article 75.5 of the Code, is to conserve the widely used name Chrysophanus florus Edwards, 1884 (currently Lycaena florus) for a butterfly species from North America by designating a neotype for Polyommatus castro Reakirt, 1866. The identity of Polyommatus castro (currently Lycaena castro) is uncertain because its lectotype is similar to the widespread lowland Lycaena helloides (Boisduval, 1852) in one trait and similar to the high-altitude Rocky Mountains butterfly Lycaena florus (Edwards, 1884) in another trait, and it lacks precise locality data that could have indicated its identity. A male of L. helloides is proposed as the neotype of L. castro, which will both fix the identity of L. castro as L. helloides, a synonymy accepted for 102 years, and conserve the name Chrysophanus florus Edwards, 1884 (currently Lycaena florus), which has been used for 125 years for the high-altitude butterfly and has been used in most of the scientific papers on the species.

Case 3468
Clusiodes Coquillett, 1904 (Diptera, CLUSIIDAE): proposed conservation of usage by designation of Heteroneura albimana Meigen, 1830 as the type species
Owen Lonsdale
Plant Pest Diagnostics Branch, California Department of Food & Agriculture, 3294 Meadowview Road, Sacramento, CA 95832-1448, U.S.A. (e-mail: Neoxabea@hotmail.com)
Abstract. The purpose of this application, under Article 70.2 of the Code, is to conserve usage of the genus Clusiodes Coquillett, 1904 (replacement name for Heteroneura Fallén, 1823) by designating H. albimana Meigen, 1830 as the type species. It has been long overlooked that the type species of Heteroneura is actually H. muscaria Fallén 1823, a species now assigned to Cnemacantha Macquart, 1835 in the family LAUXANIIDAE Macquart, 1835. It is proposed that H. albimana be designated the type species of Heteroneura in order to maintain the current usage of the name Clusiodes for a widespread, regularly collected and frequently discussed taxon in the CLUSIIDAE Handlirsch, 1884.
Keywords. Taxonomy; nomenclature; CLUSIIDAE; Heteroneura; Clusiodes; druid flies; worldwide distribution.
Case 3476
Dialictus Robertson, 1902 and Evylaeus Robertson, 1902 (Insecta, Hymenoptera): proposed precedence over Hemihalictus Cockerell, 1897, Sudila Cameron, 1898 and Sphecodogastra Ashmead, 1899

Abstract. The purpose of this petition, under Articles 23.9.3 and 81.2.3 of the Code, is to give the widely used halictine bee generic names Dialictus and Evylaeus, both proposed by Robertson in 1902, precedence over the rarely used but older names Hemihalictus Cockerell, 1897, Sudila Cameron, 1898 and Sphecodogastra Ashmead, 1899 whenever these names are considered to be synonyms. This proposal is intended to best conserve the standard usage of these names.

Case 3483
Villanyia Kretzoi, 1956 (Mammalia, Rodentia, ARVICOLIDAE): proposed conservation of usage by designation of a neotype for the type species Villanyia exilis Kretzoi, 1956

Natuurhistorisch Museum Rotterdam, Postbus 23452, 3001 KL Rotterdam, The Netherlands (e-mail: dfm1@stcatharinescollege.org)
Abstract. The purpose of this application, under Article 75.6 of the Code, is to set aside all type fixations for a species of extinct vole Villanyia exilis Kretzoi, 1956 prior to that by Terzea (1991) in order to conserve prevailing usage. The lectotype and paralectotype demonstrably belong to two different taxa. The specimen designated as lectotype by Rabeder (1981) is considered to belong to Dolomys kretzoii Kowalski, 1958 (currently Clethrionomys kretzoii). The paralectotype corresponds to the original species description and represents a taxon uniformly recognised in the current taxonomic and biostratigraphic literature as Villanyia exilis Kretzoi, 1956, which usage should be conserved.
Keywords. Nomenclature; taxonomy; Mammalia; Rodentia; ARVICOLIDAE; Villanyia; Villanyia exilis; voles; Europe; Pliocene; Pleistocene; biostratigraphy.
Case 3480 (see comments BZN 66:4)
Mastodon waringi Holland, 1920 (currently Haplomastodon waringi; Mammalia, Proboscidea): proposed conservation of usage by designation of a neotype
Spencer G. Lucas
New Mexico Museum of Natural History, 1801 Mountain Road NW, Albuquerque, NM 87104, U.S.A. (e-mail: spencer.lucas@state.nm.us)
Abstract. The purpose of this application, under Article 75.5 of the Code, is to conserve the usage of the name Mastodon waringi Holland, 1920, for a species of extinct South American proboscidean, by designating a neotype. Because M. waringi has had long and wide (though incorrect) usage as a species of Haplomastodon, and because the holotype of M. waringi is undiagnostic, the neotype designation is proposed to promote stability of nomenclature.
Keywords. Nomenclature; taxonomy; Mammalia; Proboscidea; Ecuador; Brazil; Haplomastodon; Cuvieronius; Mastodon waringi; gomphothere; South America.
