Habitus (Figures 21-22): Head brownish red; compound eyes black, rounded, arranged transversally; vertex smooth, rectangular, with a prominent median carina; ocelli closer to each other than to compound eyes; tylus smooth and rectangular with a prominent median carina; antennae brownish red, pedicel sparsely setose, basal body of flagellum ovoid with one arista as long as pedicel; postclypeus brownish red, inflated, angulose
in profile, with one longitudinal carina strongly marked and prominent, lateral grooves strongly marked; rostrum extending to mesocoxae.
Epiphylls and hypophylls differ in their adult epidermal patterns: epiphylls have larger cells, nearly isodiametric, sinuous to sinuous-angulose walls, with stellate appearance, whereas hypophylls have cells 2-3 times longer than wide, with irregular undulations, shallow and deep, angulose
