Male

Prosoma olive green, dorsal with dark grey reticulations and striae. Chelicerae light olive green. Sternum with dark reticulations at margins. Dorsum of abdomen olive green, dark grey marking anteriorly followed by chevrons broken in to dark blotches along midline. Legs whitish, very slightly darkened apically on tibia IV and metatarsi I–IV. Terminal part of conductor forms an open spiral with well separated, slender windings. The section at the very tip relatively long, straight and parallel with palpal tibia in retrolateral view. Palpal patella without an extension. Base of embolus in 7 o'clock position when viewing detached bulb dorsally. Seminal duct relatively wide and of uniform thickness, lacking a seminal loop.

Body length male: 2.1–2.6 mm
Female

Colouration as in male except for prosomal markings in front of fovea forming longitudinal cells, quite distinct in some specimens. The epigynal openings approximately circular and separated by 0.8–1.2 diameter. The round spermathecae, inseminations ducts and fertilization ducts are partly visible through the cuticle.

Body length female: 1.6–2.2 mm
Additional information
