Female: a, habitus (left side); b, c, urosome (dorsal, left, respectively); d, e, f, genital somite (ventral, left, right, respectively); g, genital somite (left, tilted clockwise); h, genital somite with operculum open. gfl = genital flange.

Nota: Length ratios of 4 urosomal somites and left caudal ramus 38.9 : 16.5 : 12.9 : 8.2 : 23.5 = 100.
Dorsal appendicular seta of left caudal ramus approximately 1.5 times longer than that of right ramus. Anteriorly, each caudal ramus with 2 pores.
