Exechia cincinnata Johannsen (Figs 37-39) This species was described from North America (USA, New England) and this is the first record for the Palaearctic. Johannsen (1912) figured the male genitalia, showing the series of bent setae on the gonocoxites. The British specimen was compared with Nearctic material which I collected a few weeks previously, in broad- leaved and mixed forest. The British site is dry broad-leaved woodland dominated by beech (Fagus). E. cincinnata is brightly coloured. The thorax is brownish yellow, more yellowish on the sides of the mesoscutum. The abdomen has large yellow markings: sides of tergite 1; most of 2-3, which have a narrow dark stripe medially, broadened narrowly on fore margin and as a triangular area on posterior half; 4 has a yellow lateral spot on basal half in British male, absent in Nearctic specimens (although present in Johannsen's types). The male genitalia (Figs 37-39) are yellow and very distinctive in structure: cerci strap shaped with dense short setae apically; gonostylus with 2 narrow lobes, the. Figs 37-39.
