Diagnosis

Frons punctate-rugose and coriaceous (Fig. 17C); head in lateral view protruding dorsally and ocelli invisible (Fig. 17D); two apical antennal segments of female much longer than six subapical segments (Fig. 17K); vein 1-R1 of fore wing 1.5× as long as pterostigma (Fig. 17G), vein 1-CU1 0.6× as long as vein 2-CU1; hypopygium acute apically, lacking an up-curved triangle or apical spine (Fig. 17I).

Etymology

Named after the long lower tooth of the mandible, from the Greek ‘ makros ’ for ‘long’ and the Latin ‘ dens ’ for ‘tooth’.
