Delia coarctoides Michelsen, sp. nov. Figs. 1, 3, 5, 7–11. Etymology. The specific epithet ‘coarctoides’ is derived from ‘coarctata’, existing name for the most similar species, and ‘­oides’, a Greek adjectival suffix meaning ‘resembling’. Material examined. Type material. Holotype male, DENMARK: Jutland (W): Årgab, reared 16.ix. 1951 from puparium found 30.vii. 1951 (K.O. Leth), ZMUC. Paratypes.

The general descriptions of D. coarctata given by Hennig (1974 a) and Griffiths (1991, 1992) also apply to the new species D. coarctoides with a few exceptions as emphasized in the following. It is reliably separated from D. coarctata in the male sex only, although a differential description of both sexes is attempted in the following: Male. Vein C on basal section, between humeral and subcostal breaks, with several v setulae vs. bare on ventral surface. Fore tibia with apical pv seta short, pointed at tip (Fig. 1) vs. long and coarse, truncated at tip (Fig. 2). Length of fore tarsomere 1 equals length of fore tarsomeres 2–4 combined (Fig. 1) vs. fore tarsomere 1 nearly as long as ...
