Bull. zool. Norn., vol 38, pt 3, July, 1981 225 NOMIOIDES SCHENCK, 1866: PROPOSED DESIGNATION OF TYPE SPECIES (INSECTA, HYMENOPTERA, HALICTIDAE). Z.N.(S.) 2178 By Yu. A. Pesenko and I.M. Kerzhner (Zoological Institute, Academy of Sciences of the USSR, Leningrad, USSR) 1 . Schenck, 1866, p. 333, established a new genus Nomioides for one species, Andrena pulchella Jurine, 1807 (with Apis parvula Fabricius, 1798 cited in synonymy). There was no redescription of the species but a reference was given to a previous good description oiA. pulchella by Schenck, 1859, p. 295). 2. It was shown by Mocsary, 1879, p. 30, and accepted by Handlirsch, 1888, pp. 398-399 and Bluthgen, 1925, p. 7, that Schenck, 1859, has misidentified Andrena pulchella. Nomioides pulchellus Jurine sensu Schenck, 1859, 1866, non Jurine, 1807, is identical with Apis minutissima Rossi, 1790, p. 109, while Andrena pulchella Jurine, 1807 is a junior synonym of Andrena variegata Olivier, 1789, p. 139, now Nomioides variegatus. The identity of Apis parvula Fabricius is doubtful; it is most probably a synonym of Nomioides minutissimus (Rossi) or of some other related species. 3. As Schenck misidentified the type species of his new genus, the type species should be designated by the Commission (Code, Art. 70a). 4. Sandhouse, 1943, p. 578, and Michener, 1965, p. 183, 1978, p. 504, indicated as type species of Nomioides 'Andrena pulchella Jurine, 1807 = Apis minutissima Rossi, 1790', but this synonymy is wrong (see above). No other citations of the type species of Nomioides are known to us. 5. It is evident that A. minutissima Rossi {= N. pulchella sensu Schenck), i.e. the species actually before Schenck, and r\o\.A. pulchella Jurine, i.e. the species named by Schenck, is understood as type species by all later authors. For example, Bluthgen, 1925, p. 4, distinguished the N. minutissima group which was later treated by Cockerell, 1935, p. 90, and Bluthgen, 1937, p. 3, as the subgenus Nomioides s.str. , while Bluthgen, 1937, p. 3, named the N. variegata group as the subgenus Eunomioides . Therefore designation oiApis minutissima as type species of Nomioides seems to be the best solution. 6. An additional problem is the gender of the name Nomioides. As indicated by Bluthgen, 1925, p. 6, Schenck, Handlirsch, Morawitz and Margetti used the name as feminine, and Mocsary, Friese, Cockerell, Alfken, Gribodo and Debski as masculine, while if we consider the origin of -ides from the Greek eidos, the name would be neuter.
