Redescription.

Female (holotype) MNB 13860.

Habitus (Figs 7-10). Integument of carapace moderately rugose in cephalic portion and coarsely rugose in thoracic part, abdomen uniformly covered with dense fine microsetae. Measurements: TL ca. 7.20 (abdomen and petiole separated from prosoma), CL 3.36, CW 2.43, CyH 0.32 (0.25 margins), tibia I L/W 1.55 (2.09/1.35). Eyes: AME 0.16, ALE 0.11, PLE 0.09, PME 0.10, AME–AME 0.10, AME–ALE 0.11, ALE–PLE 0.55, PLE–PME 0.39, PME–PME 0.36. Colour in alcohol: Carapace and chelicerae intense dark red, ventral prosoma and leg I segments from femur to metatarsus and abdominal scuta scarlet red, other leg segments yellowish-orange, unsclerotised part of abdomen pale yellowish-brown with few small dark brown marks on ventral side near spinnerets. Legs: formula 4123. Coxa I dorsally, patella and tibia I ventrally with numerous and dense small granules. Thin undivided scopula on entire ventral and proventral surface of tibia I; very thin and prolateral on metatarsus and tarsus I, elsewhere absent. Palpal tarsus, metatarsi and tarsi II–IV with ventral brushes of dense setae. PTC each with 2-4 small teeth.

Leg measurements:

Abdomen: dorsal scutum (Ds) hexagonal (Fig. 12), not fused with postgastral one, as long as wide, closely separated with epigastral scutum basally. Epigastral scutum (Fig. 11) with distinct petiolar tube (Pt) covered with transversal wrinkles, concavity shallow and not wide; postgastral scutum not solid, represented by at least 3 pairs of separate scuta, stripe-like (Ss) along book-lung slit and 2 pairs of sigilla-like scuta (Si), one pair in concavity and one pair posteriorly.

Copulatory organs (Figs 13-16): endogyne with large membranous receptacles (Re) lacking pore glands; basolateral fold (Rf) distinct; 3 pairs of grape shape glands (Gg) on each side, stalks relatively short, pore glands absent; fine threads (Ft) distinct and short.
