Head elongate, developed posteriorly eye. T2 with pair of subrounded lateral depressions, each one small setay tubercle, margins of anterior half of depression with many long setae. Posterior hypopygeal margin concave. Genitalia: paramere wide; digitus smooth upper margin; aedeagal ventral ramus very elongate, surpassing paramere apex, filamentous apically; dorsal body with two pairs apical lobes; outer pair laminar, vertical surfaces, wide base, narrowing apically in lateral view, apex inclined downward; inner lobe stout, membranous, densely setay; basal process with long and thick dorsal median filament; basal ring much developed in ventral side.
