Body length: 680 ( lectotype , male), 680–747 (measured seven specimens); notogaster width: 531 ( lectotype ), 514–547 (measured five specimens). Body color light brown. Body surface densely microgranulate (visible only under high magnification). Prodorsum with several short longitudinal striae laterobasally. Rostrum rounded. Lamellar and sublamellar lines thin, parallel, curving backwards at ventral ends. Rostral and lamellar setae approximately similar in length, long, setiform, slightly barbed. Interlamellar setae very short, setiform, smooth. Bothridial setae long, setiform, barbed. Sejugal porose areas elongate oval, transversely oriented, located posterolateral to interlamellar setae. Dorsophragmata distinctly elongated. Dorsosejugal suture present, simple. With 10 pairs of setal alveoli and four pairs of porose areas, Aa elongate triangular, transversely oriented, close to pteromorphal hinges, located anterior to la , others ( A1 , A2 , A3 ) oval. Median pore represented by single pore between A 2 in both sexes. Lyrifissures im located close and anterior to A1 . Opisthonotal gland openings located lateral or posterolateral to A1 . Four pairs of epimeral setae observed. Epimeral, genital, aggenital, anal and adanal setae short, setiform, thin, slightly barbed. Anterior edge of genital plates with two setae, but third pair located close to this edge. Aggenital setae inserted closer to genital plates than to anal plates. Circumpedal carinae of medium length, directed to insertions of setae 3b , but not reaching them. Adanal lyrifissures located close and parallel to anal plates. Adanal setae ad 1 and ad 2 posterior, ad 3 lateral to anal plates. Distance ad 1 – ad 2 similar or slightly shorter than ad 2 – ad 3 . Postanal porose area elongate oval. Median claw of legs distinctly thicker than laterals, all slightly barbed on dorsal side. Famulus on tarsi I inserted slightly anterolateral to solenidion ω 1 . Solenidion inserted in anterior part of tibiae IV.
