3.2. Subgenus Eutanycerus Foerster

Eutanycerus Foerster, 1862: 251 . Type species (by original designation). Eutanycerus halidayanus Foerster, 1862 .

Villocera Chen and van Achterberg, 1997: 123 . Type species Streblocera villosa Papp, 1985 .

Diagnosis: Eutanycerus differs from all other subgenera of Streblocera in having antenna of female not distinctly or distinctly geniculated at ninth segment, sometimes at eighth or tenth segment; scapus of female long, with or without basal horn, inner concave side usually less setose, at most apically densely setose; third segment normal, slightly longer than fourth segment; basal 7 flagellomeres usually fused; face distinctly wider than long, more or less convex, medially without an acute horn; mandible normal, without wide ventral lamella; occipital carina nearly complete, ventrally usually joining hypostomal carina; first metasomal tergite usually with dorsope, rarely without; fifth metasomal sternite of female without pair of teeth; ovipositor long, distinctly extending beyond sternites.

Remarks: Streblocera macroscapa (Ruthe) was recorded from India by Haider et al. (2003), but specimens of S. macroscapa are not found in the ZDAMU collection. Hence, this species should be treated as a doubtful record from India.

In this paper, 9 new species of subgenus Eutanycerus are described and illustrated. A key to the Indian species of Eutanycerus is also given.
