Diplazon bachmaieri Diller 1986 (syn. nov.)

Diagnosis. Fore wing length 5.2–6.5 mm. Antenna of both sexes with 16–18 flagellomeres. Face with punctures clearly distinct from the background sculpture, at least centrally. Mesopleuron smooth and shining and strongly punctate also on upper half. Propodeum with a full set of carinae enclosing basal, lateral and petiolar areas. Tergite 1 0.95–1.15, tergite 2 0.6–0.7 times as long as wide; tergites 2 and 3 with obvious coriaceous sculpture between the rather indistinct punctures, this sculpture often extending across transverse impressions. Transverse impressions deep on tergites 1 to 2, often still distinct on tergite 3 and sometimes indicated on tergite 4. Metasoma dorsoventrally depressed.

Colouration of females. Antenna dark brown. 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, only rarely a spot on subtegular ridge, small shoulder mark, upper mesepimeron; scutellum with a yellow tip. Legs orange, coxae black with a tinge of orange or entirely orange, in which case at least the trochanters are dark; femora orange; hind tibia narrowly white between the dark basal and apical bands, hind tarsus dark. Metasoma black.

Colouration of males. As in females but with yellow ventrally on scape and pedicel, entire face, subtegular ridge and some irregular area around epicnemial carina. Fore and mid coxae yellow. Tergites 1 to 3 sometimes with posterior margins dark orange.
