Two new species of Cricotopus (Cricotopus) van der Wulp are described in all life stages. Only three species of Cricotopus have previously been described from New Zealand: C. zealandicus Freeman, C. cingulatus Hutton, and C. aucklandensis Sublette & Wirth. Adult Cricotopus vincenti can be distinguished from C. zealandicus and C. cingulatus by a lack of tibial and abdominal markings, and from C. aucklandensis by a much higher antennal ratio, more antepronotal setae, and a more distinct flange on the gonostylus. C. planus can be separated from C. zealandicus by a lack of pale tibial rings, and from C. vincenti and C. aucklandensis by the presence of abdominal markings. It is similar to C. cingulatus but can be distinguished by the small, low, and flattened inferior volsella, whereas C. cingulatus has a clearly pronounced and posteriorly-directed inferior volsella. The pupa ofC.planus can be distinguished from that of C. vincenti and C. aucklandensis by the lack of a thoracic hom, and abdominal shagreen patterns. C.vincenti pupae can be separated from C.aucklandensis by the non-clubbed thoracic hom and abdominal shagreen patterns. The larva of C. vincenti is distinct from C. planus by its larger size, mentum
288029Received22 April 1988; accepted27 October 1989 morphology, and the lack of any distinctive notch opposite the seta subdentalis in the mandible, and from C. aucklandensis by mentum characteristics. Comments are made on the life cycles of each species and affinities with the overseas fauna are discussed.
