Female: figs 215-216 . Body size: 11-13 mm.

Black. Ferruginous: tip of last flagellomerus, tibiae and tarsi. Apex of fore wing slightly darkened.

Medially impressed p on head and N 1 disk, mostly with I larger than their diameter; more densely packed with I shorter than their diameter on Es 2 disk. Very weak p on Sc 1, Sc 2, coxae and metameri. P: weak p densely packed medially along the furrow, sparsely on anterior lateral corners;posterior areabipunctate by larger among many micro p. mR detectable only on metameri.

cOc complete event though a bit shortky irregular at the vertex. Gradulus on 3 rd and 4 th terga too. 6 th tergum mostly wrinkled.

Male (Holotype): figs 217-222. Body size: 13.5 mm.

Black. Yellow: mandible; the whole of clypeus but semitransparent ventral edge; subapical Tsa; apical four and three Pam and Pal respectively; subapical stripe (worn out at the middle) and anteroventral corner of N 1 disk; fore half tegula; ventral X 1 and X 2; most of fore leg; apical mid and hind tibiae; dorsal mid and hind femur; apical stripe on 1 st to 6 th terga; two small lateral apical spots on 2 nd and 3 rd terga, becoming narrow apical stripes on 4 th and 5 th sterna. Wings hyaline.

Suture of Pog expressed as prominent ridge. Well evident tyloida on last three flagellomeri, obscure one on 8 th element; mid flagellomeri with a ratio L / LA about 2.4. No acute keel along fore border nor prominent tooth on antero ventral corner of N 1 disk with a ratio LApos / Lmed about 3.2. Apical hind femur rounded. Tergal surface bipunctate by small shallow p among micro p. No p on apical surface of 1 st sternum. Epipygium without distinct notch and rounded laterally without strong carina. Volsella angled.

Variability mainly about size: males from 11 to 14 mm, females from 12 to 14 mm.

Derivatio nominis. From the Greek words ȠȜȓȖȠȢ = few and IJȪȜȘ = callosity, callus
