Male palp: RTA with large dorsal branch, distally truncated and strongly sclerotized; lateral branch developed as a weakly sclerotized point; ventrally bearing a weakly developed rounded ridge. Embolus originating (free apex) between 7 and 8 o’clock position; length (only free apex) less than 1.75 times cymbium width; distal tip between 2 and 3 o’clock position. Conductor lamella-like, distally elongated (parallel to cymbium), arcuated and laterally folded along the whole length; as long as alveolus, distally reaching beyond alveolus margin; terminal end forming sclerotized peak, pointing ventrally (in lateral view). Connection of conductor and tegulum membranous. Median apophysis originating between 4 and 5 o’clock position. Tegular apophysis absent. Prosoma length: 4.47 mm.
Epigynum and vulva: Epigynal plate sclerotized with distinct atrium, transversely oval in shape; anterior margin of atrium sclerotized at epigynal plate, gradually becoming membranous. Ground plate of atrium transversally subdivided by straight groove: anterior part membranous or weakly sclerotized, semicircular in shape; posterior part sclerotized, forming semicircular bar. Copulatory openings barely visible, located medially of atrium. Copulatory duct short and straight. Receptacula small, globular; fertilization ducts long and strongly convoluted. Prosoma length: 4.14–5.07 mm.
Eyes: Diameter: PME: 0.17–0.18; PLE: 0.18–0.21; AME: 0.13–0.18; ALE: 0.19–0.21. Distances: PME–PME less than diameter of PME; PME–AME less than or equal to diameter of PME; PME–PLE less than or equal to diameter of PME; PME–ALE less than 1.5 diameter of PME; AME–AME about 0.5 diameter of AME. Clypeus height (measured under AME) less than 2.5 times diameter of AME; (measured under ALE) about 1.5 times diameter of ALE.
Coloration: Two longitudinal symmetrical dark bands present on carapace, interrupted, sometimes reduced to triangular dots, intensified by white and black plumose hairs. Opisthosoma dark green-brownish, at the cardiac mark yellowish with dots on the sides, continuing in broad chevrons posteriorly. Legs not annulated.
Additional somatic characters: Tarsus I with 7–8 dorsal trichobothria, tarsi II–IV with 7. Colulus dark, sometimes only partially. Both segments of PLS very weakly darkened. PMS slightly smaller than ALS.
