Male: Length: 14.6–15.1 mm. Head width: 2.4–2.9 mm. Thorax width: 2.8–3.5 mm. Abdominal width 3.2–3.4 mm tapering to 1.2–1.4 mm on anal segment. Coloration: light brown; cephalic and anal tubercles and abdominal chitinous rods dark brown, darker apically; setae yellowish brown.

Head. Cephalic tubercles armed with three pairs of spines fused basally; first pair same length as second pair and placed above them; third pair ½ length of the others, placed laterally on the tubercle ( Figs. 27 and 28 ). Central pair of spines with two pairs of setae, first pair on dorsal surface, near its base, second placed laterally on basal half of spine ( Fig. 28 ). In ventral view, both anterior and posterior facial tubercles are present and totally fused, the first one with a pair of setae placed laterally, additional pair on the posterior margin ( Fig. 29 ).

Thorax. With four pairs of setae, two pairs on dorsal surface placed close together, two pairs on lateral surface; prothoracic spiracle heavily sclerotized, dark brown, raised above surface and located immediately behind head ( Fig. 26 ).

Abdomen. Segment I with transverse row of long setae, darker on apex and base, interrupted in center; segments II–V with transverse rows of chitinous rods intercalated with long, thin setae, row of setae interrupted in center; segments VI–VII with reduced chitinous rods, resembling small spines, intercalated with thin setae; segment VIII with only reduced chitinous rods; pleura and sternites with rows of strong and long setae ( Fig. 26 ), sternites I–VII with complete rows of strong setae, located in middle of the segments; anal tubercle with three pairs of spines; central pair not fused and with two pairs of projections; first pair on apical third, converging to center, second pair on the middle third and directed downwards; second and third pairs of spines are tiny and located on base of first pair, on dorsal and ventral surfaces respectively; additional single spine on dorsal base of the tubercle ( Figs. 30 and 31 ); abdominal spiracles slightly darker and more sclerotized than surrounding area, raised above surface and placed laterally on segments I–VII.
