Fore wing length 3.5–4.4 mm . Antenna of both sexes with 14–15 , rarely 16 flagellomeres. Face with punctures clearly distinct from the background sculpture. Mesopleuron smooth and polished with rather weak but quite frequent punctures. Propodeum with a full set of carinae enclosing basal, lateral and petiolar areas. Tergite 1 0.8–1.1 , tergite 2 0.5–0.6 times as long as wide; tergites 2 and 3 with large, distinct punctures on a rugose or on tergite 3 rather smooth and polished background, punctures with distinct margins. Transverse impressions deep on tergites 1 to 4 in females, 1 to 3 or 4 in males. Metasoma dorsoventrally depressed. Colouration of females. Antenna dark brown, sometimes paler below. Head and mesosoma black, face with yellow along inner orbits, without yellow central face patch, yellow on clypeus and mouthparts, hind corner of pronotum, tegula, subtegular ridge, shoulder mark, upper mesepimeron; scutellum at least with an apical spot, often largely yellow. Legs orange, coxae black, fore and mid coxae with yellow apices; femora orange; hind tibia blackwhite-black banded, sometimes apical band with an orange or orange-brown area, hind tarsus dark. Metasoma black, tergite 1 often with a white hind margin, tergites 2 and 3 sometimes with apical orange bands. Colouration of males. As in female, yellow colour largely reduced, usually without central yellow face patch. Material examined. New for Slovenia : Untersteiermark, Podčetrtek, leg. Dr.Jaeger, 3 .IX. 1935 . 1♀, at ZSM . France ( 1 ), Germany ( 1 ), Hungary ( 13 ), Russia ( 1 ), Sweden ( 2 ), Switzerland ( 14 ). Distribution. Palaearctic and Oriental. Figures. Metasoma ( Fig. 13 A ). Notes. The delimitation of D. multicolor has caused problems with identification in the past and has only been removed from synonymy with D. annulatus recently ( Klopfstein 2011 ). But the short antennae, stout metasoma and often characteristic colouration clearly separate D. multicolor from the otherwise similar D. annulatus .
