Diagnosis

Eye large, in lateral view 2.1× as wide as temple ( Fig. 31D); vein 2-SR of fore wing strongly bent and subparallel with posterior margin of pterostigma ( Fig. 31G); first and second tergites of metasoma coarsely and sparsely rugose ( Fig. 31I); hypopygium apically truncate ( Fig. 31M); clypeus rather protruding ventrally ( Fig. 31E); lower tooth of mandible indistinct and very small ( Fig. 31L); third tergite in dorsal view densely rugose and truncate ( Fig. 31I); vein 1-M of fore wing brown, darker than yellowish vein M+CU ( Fig. 31G); hind tibia with brownish yellow patch subbasally and apically ( Fig. 31K).

Etymology

Named after its conspicuous tegulae, from the Latin ‘ tegula ’ for ‘shingle’.
