Pegomya glabroides Michelsen, sp. nov. Figs. 24–31. Etymology. The specific epithet ‘glabroides’ is derived from ‘glabra’, existing epithet for the first species of the P. terminalis species group described from the Nearctic Region, and ‘-oides’, a Greek adjectival suffix meaning ‘resembling’. Description. Very small to small (WL 3.0–3.9mm; n=16). Male. Externally closely resembling P. terminalis except for smaller size and brownish black colouring on all parts of head, body and appendages. Terminalia (Figs. 24–29) also similar, but lobes of sternite V (Figs. 24, 25) broadly obtuse and with only a few lateral setae, surstyli (Figs. 26, 27) with meso-basal laminate process more prominent in profile view and meso-distal process shorter, broad-based and with fewer setulae, and gonites overall (Fig. 28) shorter. Female. Differing from P. terminalis by being extensively brownish black in ground-colour; only lower portion of frontal vitta and tibiae to varying extent orange-brown. Abdomen with black shine through thin layer of grey dusting, without any indication of a mid-dorsal stripe. Readily separated from P. granadensis by smaller size, absence of discal setae on tergite V and fewer hind marginal setae on sternite V. Oviscapt (Figs. 30, 31) with cerci distinctive: relatively large, discoid, with a cutting edge formed along inner apical margins. Material examined. Type material.
