Protodasyapha (P.) hirtuosa (Philippi)

MALE

Mandibles: Absent.

Lacinia : ( Fig. 8 ). Total mean length = 60 µm (n = 10). Greatest mean width = 49 µm (n = 10). Dorsomedial surface totally covered with abundant micropilosity oriented towards the apex; apex acute, without teeth. Ventral surface bare, without teeth.

Labrum ( Fig. 9 ). Total mean length = 462 µm (n = 10). Greatest mean width = 83.4 µm (n = 10). Dorsal surface with longitudinal swelling, approximately to within 30 µm of the apex, with a smooth, bare region, laterally with microtrichiae oriented towards the apex, diminished in number near the margins and apex, replaced by long and abundant micropilosity. Apex acute with long micropilosity, and without microteeth. Ventral surface smooth, with long and sparse micropilosity along the margin; bare medially.

Hypopharynx: ( Fig. 10 ). Total mean length = 549 µm (n = 10). Greatest mean width = 90.8 µm (n = 10). Apex acute, with sparse micropilosity. Dorsal surface smooth, salivary duct opening approximately 100 um before the apex, sides straight. Ventral surface smooth.

FEMALE

Mandibles: Absent.

Lacinia : ( Fig. 11 ). Total mean length = 763 µm (n = 10). Greatest mean width = 65.3 µm (n = 10). Apex rounded, without teeth. Dorsal surface totally covered by abundant, uniform micropilosity, oriented medially and toward the apex. Ventral surface bare.

Labrum: ( Fig. 12 ). Total mean length = 536.1 µm (n = 10). Greatest mean width = 111 µm (n = 10). Dorsomedial surface with evident swelling that is flattened approximately 35 um before the apex. Microtrichiae of the dorsal surface sparse, more abundant towards the apex. Apex acute, lateral edges with long, abundant micropilosity oriented toward the apex, without microteeth. Ventral surface bare medially.

Hypopharynx: ( Fig. 13 ). Total mean length = 659 µm (n = 10). Greatest mean width = 84.4 µm (n = 10). Apex acute. Dorsal surface smooth, bare. Salivary duct opening approximately 200 µm before the apex, without microtrichiae or micropilosity. Ventral surface smooth, bare.
