Reshchikov A, Choi J-K, Xu Z-f, Pang H (2017) Two new species of the genus
The two new species from Northern Thailand were collected by Malaise traps during the TIGER project (
Landscape and type habitat of
The genus
1 | Lower mandible tooth distinctly longer than upper one (Fig. |
|
– | Lower mandible tooth as long as or slightly longer than upper one; lobe of oral carina weakly defined and weakly elevated behind mandible (Fig. |
|
2 | Face with strong central bulge (Fig. |
|
– | Face without central bulge (Fig. |

This species differs from other Oriental species by a combination of the following characteristics: lower mandible tooth slightly longer than upper; lobe of oral carina weakly elevated behind mandibles (Fig.
Female (holotype). Body length 6.0 mm. Fore wing length 5.5 mm. Flagellum with 35 flagellomeres, about as long as fore wing; two basal flagellomeres almost as long as maximum diameter of eye; first flagellomere 3.6 × as long as apical width. Head narrowed posteriorly (Fig.
Pronotum coarsely and densely punctate, with distinct epomia (Fig.
T1 1.5 × as long as apical width; its longitudinal carinae extending to 0.6 × its length; space between carinae smooth, with fine punctures; dorso-lateral carinae complete. T1 (beyond spiracles) and T2 completely smooth, more or less evenly covered with fine punctures (Fig.
Color. Antenna (except for basal flagellomeres ventrally), head, mesosoma, coxae, trochanters, most of fore and mid femora, apical part of hind tibia, hind tarsus, and pterostigma black (Figs
