Retromargin has four teeth smaller than those in promargin, apical tooth strongly triangular and broad basally, third tooth the smallest and basal tooth the largest. Pedipalp yellow with hairy and spinous tarsus, tarsal claws without teeth. Dorsum of pedipalp’s tibia bears three trichobothria in increasing length towards midlength, submedian trichobothrium the longest, approximately 0.75x tibial length and 3x longer than tibial diameter. Maxillae yellow brown, longer than wide and almost parallel-sided. Maxillae, labium, and sternum pattern as in the genus Leucauge .

Sternum lined with black hairs converging towards the middle, apical rows of hairs distinctly longer than those in posterior one-half.

Eye separation (mm): AME-ALE (0.29)> PME-PLE (0.26)> PME-PME (0.14)> AME-AME (0.11). Median ocular quad wider behind than in front (0.33: 0.39 mm) and posterior width slightly shorter than height (0.40 mm).

Legs. Yellow except black anterior tip of segments, long and slender. Spination in femur I 0-0-6-3, II 1 -0-4-3 and IV 3 -0-2-2; tibia I 2 -0-3-3, II and IV 2 -0-2-2; metatarsus I 1 -0-1-2, II with 1-0-1-1 and IV 1-1 -2-2.
