Abstract

Gynandromorphy, where part of an individual is male and part female, is a recognised phenomenon in insects. It has been recorded in many insect groups including the Lepidoptera (Ford, 1955, Ellis, 1993) and the Hymenoptera. Within the Hymenoptera there have been most records in the Apocrita (recent records reviewed in Nilsson, 1987) but there are a small number of records of gynandromorphic sawflies (Symphyta). These include records of both diprionid (Heliövaara et al., 1992) and tenthredinid sawflies (McLachlan, 1867; Peacock, 1925, Nuorteva & Kontuniemi, 1972) but for very few species in this taxonomic group. This paper describes a gynandromorphic specimen of Pachynematus clitellatus, a species for which this phenomenon has not previously been recorded.
