Colour: Ferrugineous red, antennae and legs of light colour.
Sculpture and hair pattern: Whole body covered with dense, short and long hairs; long hairs erect and suberect, short hairs decumbent, most hairs curved at tip; anterior clypeal margin with 6 short median setae. Dorsal concave area of head and mandibles smooth, surrounding areas of head appear smooth in certain reflections, while faintly punctate with setigerous pits; region in between eyes and base of mandibles longitudinally striate; neck of pronotum shagreened; pronotum anteriorly with transversely arched striae, median portion smooth, posteriorly with faint longitudinal striae, sides of thorax finely punctate; propodeum finely punctate; upper region of propleura and a small area on mcsopleura smooth, metasternite above coxae striate and punctate; mesonotum rugoso punctate; post petiole dorsally smooth; gaster smooth.
Head: Distinctly longer than broad; posterior margin medially deeply emarginate; sides finely margined; frontal lobes extended forwards; lobes reaching vertex and join with posterior 'U' shaped margin of vertex; antennae arising from beneath anterior lamina of these lobes; in full face view cheeks hidden under frontal lamina; mandibles broad, massive, triangular, masticatory margin with 5 black teeth; clypeus very small, its posterior and lateral margins indistinct, anterior margin transverse with four short setae at its middle, clypeus a little depressed downwards; no distinct scrobe. Antennae very short, 11 jointed, club formed of apical two joints; terminal club segment longest, its length 0.6 x length of remaining segments of flagellum; F2-F7 transverse; FS subequal, F1 and club elongate; flagellum length 2.1 x scape; eyes very small consisting only two ommatidia; in profile, postero-dorsal edge ofhead finely angulate; ventromedian portion of head swollen and medially carinate, carinae starting from edge of' vertex end on either side of this median carina.
Thorax: Somewhat gibbous; pronotum with a short neck in front; antero-lateral corners rounded; mesotnetanotal suture distinct, propodeum posteriorly with two short teeth which project backwards and shorter than their basal width; propodeum medially concave; metathoracic spiracles almost at middle of stemites; metastemal teeth bluntly angulate, legs· short, stout; mid and bind ubiae without spurs; hind metatarsus 0.7 x length of femur.
Abdomen: Petiole with a short, stout peduncle in .front; node about 1.3 x length of peduncle; petiole distinctly transverse; sides straight, its length; breadth in dorsal view 3:7; postpetiole broader than petiole, transverse, flat above, postero-median part slightly depressed; length: breadth in dorsal view 5:10. Gaster broad; flat above, ventrally convex, T1 covering more than half its length.
Type Material
Holotype: Dealate female: India, Kerala, lritty Forest near Aaralamfann; Sheela. S; 16.xii.1995 (DZCU).
Etymology
Genus named after the genus Blepharidana and species name "napro" is taken from sanskrit word meaning eyes.
