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’.
