Description of male: Habitus as in Fig. 1D . Total length 5.45. Carapace 2.34 long, 1.63 wide. Eye sizes and PME interdistance: AME: 0.11, ALE: 0.14, PME: 0.13, PLE: 0.14, PME–PME: 0.07. Chelicera with 2 prolateral and 3 retrolateral teeth. Carapace, sternum, labium, chelicera, and maxilla light brown. Carapace with two patches of light gray setae on pars thoracica. Legs the same colour as the carapace, without annulations. Abdomen light cream without any pattern. Spinnerets uniformly light yellow. Leg I measurements: 6.14 (1.64, 0.31, 1.41, 1.47, 1.31).

Palp as in Figs. 4C , 5 E–F. Patellar apophysis ca 1.5× longer than wide, with subparallel margins, rounded at tip. Tibia with thin retrolateral apophysis, slightly bent ventrally, and small knob-like dorso-retrolateral apophysis. Cymbium with long tip (as long as tegulum length). Tegulum ovoid, slightly longer than wide; tegular apophysis strongly bent (90°) in retrolateral view; base of conductor very broad, 1/3 of the tegulum width, terminus of conductor gently bent, abrupt, with extended tip of the dorsal ridge (Dr). Embolus with wide base and stick-like embolus proper.

Description of female: Total length 6.55. Carapace 3.01 long, 1.91 wide. Eye sizes and PME interdistance: AME: 0.11, ALE: 0.16, PME: 0.11, PLE: 0.15, PME–PME: 0.10. Body colouration as in male. Leg I measurements: 7.53 (1.98, 0.91, 1.59, 1.70, 1.35).
