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.
