PAPP, Budapest PAPP, L.: Notes on the genus Richardsia L. Papp (Diptera, Sphaeroceridae). - Annls hist-nat Mus. natn. hung. 1991,83: 000-000. Abstract - The copromyzine genus Richardsia L. PAPP, 1973 (with its type-species mongolica (L. PAPP, 1973)) is revised; the way of the character analysis applied (NORRBOM & KIM 1985a) allows a quick comparison to any genus in the tribe Copromyzini. The characters of the male as well as of the female terminalia for analysing phylogenetic relationships are discussed. With 8 original figures. Richardsia was described as a mo no typic subgenus of Copromyza FALLÉN (PAPP 1973) from Mongolia and listed in the new Catalogue of Palaearctic Diptera (PAPP 1984) without any additional data. Indeed, that species was not collected after its description. In the last five years the majority of the genera in the tribe Copromyzini has been revised. NORRBOM & KIM published excellent revisions on Crumomyia MACQUART and Alloborborus DUDA (1985a), on Metaborborus VANSCHUYTBROECK (1985b), on Copromyza s.str. (1985c) and on Gymnometopina HEDICKE (1987). NORRBOM & MARSHALL (1988) revised Lotophila LIOY, PAPP (1988) described a new genus Norrbomia for a majority of the former "Borborillus" with several new species. (The species of Achaetothorax are under revision and will be published in the near future by PAPP & NORRBOM; A L. NORRBOM [pers, comm.] has commenced the revision of Dudaia HEDICKE). The genus Richardsia was actually mentioned and partly discussed by NORRBOM & KIM (1985a) only: there a key was also given for the Holarctic genera and the elevation of the rank of Richardsia to the generic level was formally performed. Its type (and only known) species mongolica is known only from Mongolia (it was not found in North America [A L. NORRBOM, pers. comm.], i.e. it is not a Holarctic species). Its life-habits show the plesiomorphic state in Copromyzini (coprophagous on horse dung). In all probability its larvae belong to the primary coprophagous larvae (like those of all species of Norrbomia, Borborillus, etc.). The character analysis below follows NORRBOM & KIM'S (1985a: 65 characters with two to six character states) as for numbering and character states, since that consequence of characters was used in several papers and so it will be possible to compare Richardsia to any other genus. After that list, those characters are given, which do not fit into NORRBOM & KIM'S list. Richardsia L. PAPP, 1973: 373-4 (as a subgenus of Copromyza FALLÉN, 1810). Type-species: Copromyza (Richardsia) mongolica L. PAPP, 1973: 374-6 (Figs 8,16, 40,46, 49). Material studied: holotype male and all the para types (preserved in the HNHM).
