Enizemum nigricorne  ( Thomson 1890, Homotropus  )

Diagnosis. (Male unknown). Fore wing length 5.1–6.8mm. Antenna in females with 23–24 flagellomeres, dark brown, with ventral surface of apical flagellomeres covered with a velvety pile, devoid of multiporous plate sensilla which are restricted to lateral and dorsal sides. Mesoscutum and mesopleuron with punctures small and very dense, interspaces finely coriaceous. Propodeum with pleural and lateral longitudinal carinae present, median longitudinal and transverse carinae present only as traces. First tergite with median dorsal carinae converging over entire length of the tergite, thus rather evenly curved ( Fig. 14View FIGURE 14. A F). Second tergite with basal carinae weak.

Colouration of females. Antenna dark brown, sometimes paler below. Head and mesosoma black, face with or without yellow central face patch, often orange on clypeus and mouthparts, often yellow on hind corner of pronotum, tegula, subtegular ridge, small shoulder mark and upper mesepimeron; scutellum sometimes with yellow tip. Legs and coxae orange; femora orange; hind tibia with a white base, remainder dark, hind tarsus dark. Metasoma black.

Figures. First tergite ♀ ( Fig. 14View FIGURE 14. A F).

Notes. Manukyan (1995) synonymized Homocidus rubiginosum Schmiedeknecht  , a species described from a single male from Germany, with E. nigricorne  . Homocidus rubiginosum  is, however, conspecific with E. scutellare (Lange)  (syn. nov.), according to Erich Diller who examined the male type in Berlin (personal communication). Males of E. nigricorne  thus remain unknown.
