Body length. (paratypes). mm (holotype); , mm Description. Female. Body (Fig. 1A,B) oval in dorsal view. Cephalosome and first pedigerous somite separate; fourth and fifth pedigerous somites completely fused; poste- rior corner of prosome produced posteriorly into rounded lobe directed backwards, reaching half length of genital double-somite. Urosome (Fig. 1C) 4-segmented, one-third as long as prosome; genital double-somite (Figs 1D,E,2A,B) wider than long; pair of medial gonopores (Fig. 2C,D) located ventro-laterally near mid-level of double-somite; paired copulatory pores posterior to gonopores, each con- cealed beneath ventrolateral projection; remnants of diver- gent fertilization tubes of spermatophore (Fig. 3) still attached to genital double-somite of both paratypes, each connecting through posteroventral groove with copulatory pore beneath projection; copulatory duct swollen in ventro- lateral projection, almost horizontal, extending to large semi- nal receptacle; 1 medial and 2 pairs of lateral shallow chitinized pits anteriorly; anal somite small, anal operculum not developed; caudal ramus (Fig. 1C) longer than wide, fringed with long setules along inner margin, with vestigial seta I and developed setae II to VI, seta VII originating dorsally near base of seta VI; inner margin near anus with patch of minute spinules.
