on anal segment. Coloration: light brown; cephalic and anal tubercles and abdominal chitinous rods dark brown, darker apically; setae yellowish.
Head. Cephalic tubercles armed with three pairs of spines fused basally. First pair same length as second pair, directed downwards; third pair 2/3 length of others, and placed laterally (
Figs. 2 and 3
). Central pair of spines with two pairs of setae, first pair on dorsal surface, near its base, second placed laterally on the basal half of the spine (
Fig. 3
). In ventral view, anterior facial tubercle half length of central pair, with a pair of setae placed laterally, additional pair on posterior margin; posterior facial tubercle missing (
Fig. 4
).
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. 1
).
Abdomen. Segment I with transverse row of long setae interrupted in center; segments II–V with transverse row of chitinous rods, gradually shorter beyond lateral margins, intercalated with long, thin setae, row of setae interrupted medially; segments VI–VII with reduced chitinous rods, resembling small spines, intercalated with thin setae; segment VIII only with row of reduced chitinous rods; pleura and sternites with row of strong and long setae, sternites with a complete transverse row located in middle of the segments (
Fig. 1
); anal tubercle with three pairs of spines, central pair completely fused, except at apex; the second and third pairs tiny and located on the base of the first pair, on dorsal and ventral surfaces respectively; additional single spine on dorsal base of the tubercle (
Figs. 5 and 6
); abdominal spiracles slightly darker and more sclerotized than surrounding area, raised above surface and placed laterally on segments I–VII.
