Diplazon annulatus ( Gravenhorst 1829, Bassus )

Bassus lapponicus Zetterstedt 1838

Diagnosis. Fore wing length 4.2–4.7 mm. Antenna of both sexes with 16–17 flagellomeres. Face with punctures distinct from the background sculpture only on central, elevated part. Mesopleuron smooth and polished, strongly punctate over lower half and along anterior margin. Propodeum with a full set of carinae enclosing basal, lateral and petiolar areas. Tergite 1 1.1–1.3, tergite 2 0.6–0.7 times as long as wide; tergites 2 and 3 mainly rugose, usually with some distinct punctures at least on tergite 3, the rugose sculpture not extending across transverse impressions. Transverse impressions distinct on tergites 1–3. Female metasoma dorsoventrally depressed, laterally compressed only at the tip.

Colouration of females. Antenna dark brown or black. Head and mesosoma black, face with yellow along inner orbits, without yellow central face patch, yellow centrally on clypeus and mouthparts, hind corner of pronotum, tegula, shoulder mark, upper mesepimeron; scutellum usually only with a yellow tip. Legs orange, coxae black, fore coxa often with a yellow apex, trochanters and part of trochantelli black; femora orange, not marked with black below; hind tibia black-white-black banded, hind tarsus dark. Metasoma black.

Colouration of males. As in females but with yellow ventrally on scape and pedicel or entire antenna, central yellow face patch or entire face. Fore and mid coxae and trochanters often largely yellow. Fore and mid legs often yellow.

Material examined. Lectotype of Bassus lapponicus Zetterstedt : Sweden, Södermanland, Björkvik. 1 ♀, at ZIL.

Finland (1), Germany (1), Sweden (3), Switzerland (25). Distribution. Holarctic.

Figures. Habitus ( Fig. 28 View FIGURE 28 E).

Notes. The type of Diplazon annulatus Gravenhorst is unfortunately lost ( Townes et al. 1965) and the specimens reported under this name by other authors in the past included additional species, such as D. multicolor , D. varicoxa and the newly described D. flixi (see those for diagnostic characters). I here use the most common interpretation of the species ( Schmiedeknecht 1926; Beirne 1941). As it also corresponds to the lectotype of the synonym D. lapponicus , it is unnecessary to fix a neotype at this point.
