Case 3470
Halectinosoma Vervoort, 1962 (Crustacea, Copepoda, Harpacticoida): proposed conservation of usage by designation of Ectinosoma chrystalii Scott, 1894 as the type species and by giving it precedence over Pararenosetella Lang, 1944

Abstract. The purpose of this application, under Articles 23.9.3 and 81.2.3 of the Code, is to conserve the widespread usage of the name Halectinosoma Vervoort, 1962 for a common genus of primarily marine harpacticoid copepods in the family ECTINOSOMATIDAE. The name Halectinosoma is threatened by the senior subjective synonym Pararenosetella Lang, 1944 (type species Ectinosoma erythrops Scott & Scott, 1896). In the interest of stability and universality it is proposed to set aside all previous type fixations for Halectinosoma Vervoort, 1962 and designate Ectinosoma chrystalii Scott, 1894 as the type species. The originally designated type species is Ectinosoma sarsii Boeck, 1873, but this species is now considered as being incertae sedis in the family ECTINOSOMATIDAE and its generic affinity is uncertain. It is also proposed that Halectinosoma Vervoort, 1962 be given precedence over Pararenosetella Lang, 1944 whenever the two names are considered to be synonyms.

Case 3471
Heterolaophonte Lang, 1948 (Crustacea, Copepoda, Harpacticoida): proposed precedence over Mesolaophonte Nicholls, 1941 and Monolaophonte Nicholls, 1941

Abstract. The purpose of this application, under Articles 23.9.3 and 81.2.3 of the Code, is to conserve the generic name Heterolaophonte Lang, 1948 for a group of marine harpacticoid copepods (family LAOPHONTIDAE) by giving it precedence over the unused senior names Mesolaophonte Nicholls, 1941 and Monolaophonte Nicholls, 1941 whenever these names are considered to be synonyms.

Palaemon rosenbergii De Man, 1879 (currently Macrobrachium rosenbergii; Crustacea, Decapoda): proposed conservation of usage by designation of a neotype

Abstract. The purpose of this application, under Article 75.6 of the Code, is to conserve the usage of the specific name of Macrobrachium rosenbergii (De Man, 1879) for a commercially important giant freshwater prawn from Southeast Asia by designating a neotype. Recent taxonomic reappraisals show that the two subspecies of this prawn, Macrobrachium rosenbergii rosenbergii (De Man, 1879) and M. rosenbergii dacqueti (Sunier, 1925) are in fact distinct species. The usage of the name M. rosenbergii for the species of prawn that is predominantly fished, cultured and studied by biologists is threatened, as its recently designated lectotype is M. dacqueti, while the holotype of M. rosenbergii is a different species, which has generated much less commercial and scientific interest. As substantial confusion will result if the names are changed, it is proposed that the existing holotype of Macrobrachium rosenbergii (De Man, 1879) be set aside and the lectotype of M. dacqueti (Sunier, 1925) be designated as neotype of Macrobrachium rosenbergii in its place. This action will allow biologists to retain the name M. rosenbergii for the commercially valuable species and will result in the less frequently used name M. dacqueti becoming a junior objective synonym of M. rosenbergii. For the species defined by the current holotype of M. rosenbergii, a new name Macrobrachium wallacei is proposed and a holotype is designated.

Abstract. The purpose of this application, under Article 75.6 of the Code, is to conserve the established and current species concept and usage of the name Myopa testacea (Linnaeus, 1767). This usage is threatened by the designation of a specimen in Linnaeus’s collection as a lectotype of Conops testacea which implied that the name was misapplied by previous authors. This designation has not so far been accepted by any subsequent authors, and it is therefore proposed that the long established usage of the name be conserved by setting aside all previous type fixations for M. testacea (Linnaeus, 1767) and that a neotype that is in accord with the current use of the name be designated.

Case 3466
Pachyramphus G.R. Gray in Gould, 1839 (July) (Aves, Passeriformes): proposed conservation of usage of the generic name

Abstract. The purpose of this application, under Article 23.9.3 of the Code, is to conserve the name Pachyramphus G.R. Gray in Gould, 1839 (July) (family COTINGIDAE) in its accustomed usage, for a genus of cotinga from Central and South America. It is proposed that the name Pachyramphus Gould, 1839 (January) and all its uses before July 1839 be suppressed.
Keywords. Nomenclature; taxonomy; Aves; Passeriformes; COTINGIDAE; TYRANNIDAE; Pachyrhynchus; Pachyramphus; Psaris cuvierii; Pachyramphus viridis; Central America; South America; cotingas; becards.
