Prosoma: with distinct granulation; chelicerae relatively slender, armed with one discrete promarginal tooth.

Opisthosoma: with indistinct pattern, general cream colouring, with three more or less distinct median white spots, a brown band on the flanks running backwards over the spinnerets, ringed with brown; ventrally, a white spot behind the epigastric furrow surrounded by a dark band.

Palp: cymbium distinctly longer than palpal tibia; bulbus with two tegular apophyses, TTA 1 at prolateral side, very wide at the base, relatively short, barely extending beyond the distal edge of the bulbus, curved, the terminal part slightly pointing ventrally; TTA 2 at retrolateral side, base wide, extending below the embolus by a thin curved lamellar projection; embolus curved and almost reaching tip of cymbium; conductor membranous, ovoid in lateral views, with bluntly rounded tip reaching tip of cymbium; retrolateral distal edge of alveolus with internal projection.

Body length male: 3.3–3.5 mm

Prosoma: smooth, cephalic part with long setae.

Opisthosoma: purple, dorsally with a white anterior belt and several series of white spots (one median line of three spots almost touching, two lateral lines consisting of three clearly separated spots, laterally one line of two spots, sometimes less clearly visible); ventrally, a
white spot behind the epigastric furrow.
