Diagnosis:
this species is easily recognized by the broadly interrupted apical bands of white pilosity on T2 to T5 contrasting with the black hairs elsewhere on the metasoma.
HOLOTYPE
(MALE):
Dimensions
: Approximate total length: 8.04; head width: 3.08; forewing length: 6.86; length of F1: 0.27; length of F2: 0.74; length of F3: 0.65.
Coloration
: Black, basitarsi dark brown, rest of tarsi light brown. F1 to F10 dark brown with anteroventrally area light brown. Clypeus yellow with two black laterobasal spots near the epistomal suture. Labrum yellow with dark brown margin. Mandible with yellow basal spot. Veins dark brown. Pygidial plate orange apically. Claws dark brown. Wings hyaline.
Punctation
: strong and relatively not very dense on clypeus, dense on labrum, paraocular area and especially on ocellocular area. Mesosoma finely reticulate and with dense punctation, except on mesoscutum. Metasoma with dense and relatively uniform punctation, with smooth apical impressed areas on T1 to T5.
Pubescence
: occipital area, labrum, mesepisternum, propodeum and femora with white pilosity. T1 to T4 with a distal band of white hairs widely interrupted medially. Rest of the head and legs, mesoscutum and scutellum with yellowish pilosity. Rest of the metasoma covered with black pilosity on terga, and light brown on sterna, being darker on S6.
Structure:
Vein 1°m-cu of forewing sharply angled at the base of the 2nd submarginal cell. Tibial spur of middle legs almost straight, with apex slightly curved. Basitibial plate present, rounded and flat. Pygidial plate elevated and with open apex, confluent with distal margin of the tergum. Distal edge of T7 rounded and carinate. Claws with a well-developed internal tooth.
