Amenia imperialis Robineau-Desvoidy n.stat.

Amenia imperialis imperialis Crosskey, 1965: 109 .

Dr Crosskey has kindly checked his neotype of A. imperialis (in the British Museum of Natural History) and my present application of the name is clearly valid. The species is distinguished from others in the group by the attributes given in the key, in particular the non-pollinose parafacials and the colouring of the calypters, and, in the male, the ad setae of the hind tibia and the presence of medial marginal bristles on abdominal T3. Also, the Mbend index is 0.9-1.4 (almost always greater than 1.0) and the antennal segment ratio 2.6-3.5 for males and 2.3-3.4 for females. Crosskey's male specimen that lacked bristles on abdominal T3 seems likely to have been the new species, A. crinita , described below. On the 潴桾爠 hand, I have seen a single female specimen (Kandos NSW, 13-15 May 1981, B.J. Day; AM) that has a male-like pair of submedian marginal bristles on abdominal T3. It is otherwise a perfectly normal specimen of A. imperialis .

I have one new rearing record: a male (24 km S of Barraba, NSW, 3 April 1990, P. Colman; AM C.329311) reared from Gaiadistes marcescens ( Cox ) ( Camaenidae ). Distribution. Eastern Australia, from Cape York and Torres Strait Islands to Adelaide, largely on the coast and adjacent ranges, but occasionally taken well inland (Fig. 5; the morphometrically distinct specimens are shown separately.)
