P5-bearing somite largely as in previous somite. Second (genital somite) and third urosomites separated dorsolaterally but fully fused ventrally forming genital double-somite; both halves with tube-pores and posterior sensilla as shown, with posterior margin coarsely serrated; ventral surface of anterior half —genital somite— with P6, and one patch of small spinules close to lateral margin and one outer distal pointed projection on each side; each side of ventral surface of posterior half —third urosomite— with patch of small spinules at the base of outer distal projection, and short row of long slender spinules between pair of sensilla as depicted, medially with transverse row of small spinules between innermost pair of sensilla. Fourth urosomite largely as posterior half of genital double-somite dorsally and laterally; ventrally with additional pair of tube-pores and pattern of four crescentic sets of spinules between innermost pair of sensilla. Fifth urosomite largely as previous somite but without medial tube-pore dorsally, without sensilla; ventrally without tubepores or sensilla, with pattern of surface minute spinules on posterior half, and with pattern of long posterior spinules as shown. Anal somite slightly wider than long; with one dorsolateral tube-pore on each side; with well-developed semicircular anal operculum ornamented with small denticles on surface and along posterior margin giving a serrated appearance and flanked by pair of sensilla; ventrally cleft medially, with pair of tube-pores medially and subdistally close to joint with caudal rami, with inner small spinules along inner margin of medial cleft and larger ones close to joint of caudal rami. Caudal rami twice as long as wide; dorsally with inner row of small spinules medially and at base of seta III, and with subdistal tube-pore; ventrally with comparatively longer spinules along posterior margin, and with two tube-pores as shown; with seven setae as follows: setae I and II aligned, issuing midway lateral margin, the former ventral to and about half as long as the latter; seta III displaced ventrally, slightly posterior to setae I and II, visibly longer than the latter; seta IV about half the length of seta V, slightly longer than supporting ramus; seta V nearly as long as anal somite and caudal ramus combined, posterior half rat-tail-like; seta VI issuing at inner distal corner, as long as seta II; dorsal seta VII triarticulated, as long as seta III.
