Abdominal terga rough, slightly varying in length. Median segment with anterior margin convex and posterior margin almost truncate. Second tergum longer than wide, slightly narrowing towards the posterior, about 1.3 times as long as median segment. Third to fifth terga equal in length, with indistinct median longitudinal carina and lateral margins broadly concave. Fourth and fifth terga thickened and with a pair of humps posteromedially, posterior one larger. Sixth to seventh terga equal in width, shorter than fifth tergum, with median longitudinal carina and lateral margins broadly concave. Eighth to ninth terga gradually increasing in width. Ninth tergum with distinct median longitudinal carina gradually ascending, present as ridge-like structure posteromedially. Anal segment square in outline, dorsoventrally flattened, notched posteromedially, equal in length to ninth tergum; posterolateral angles rounded. Poculum more or less triangular in lateral view, with numerous granules of irregular sizes; posterior rim flattened dorsoventrally and notched posteromedially; posterolateral angles rounded. Cerci small and flattened, not reaching posterior margin of the anal segment, with apex rounded.

Profemora slightly curved basally; antero-dorsal carina distinct and undulate; postero-ventral carina with three indistinct elevations. Postero-dorsal carina of mesofemora with two fin-like teeth; postero-dorsal carina of metafemora with three fin-like teeth, median one largest. Antero-dorsal carina of meso- and metafemora indistinct and unarmed. Antero-ventral and postero-ventral carinae of meso- and metafemora with two small teeth subapically, and with two indistinct elevations medially and basally. Tibiae with indistinct carinae except for protibiae, shorter than corresponding femora. Protibiae with distinct dorsal carinae with an indistinct elevation medially. Meso- and metatibiae with indistinct postero-dorsal carina with an indistinct elevation medially.

). Capsule brown to dark brown, with small brownish elevations. Capsule and operculum covered with very sparse, short dark setae and densely punctulate. Micropylar plate trilobate with one anterior expansion and with two posterior expansions; anterior expansion slightly widening towards the capsule; posterior arms laterally directed and faded, not reaching ventral margin. Margin of micropylar plate elevated and widened. Micropylar cup distinct, placed near the posterior end of the micropylar plate. Operculum oval, elevated centrally; outer rim dark, with brownish elevations of irregular shape. Median line dark and indistinctly raised. Ventral margin oblique in lateral view.
