Type material. Holotype: Male, LAOS: Houaphan Province, Vieng Thong district, Tham Mak Sak , 20°27 ’0L8” N, 103°23 ’34.7” E, 840 m altitude, Helmut Steiner leg. 20.I.2012, F48-123-008 , Northern LaoEuropean cave project 2010 ( SMF) GoogleMaps .

Etymology. The specific name is derived from the Latin word “erectus” meaning "upright, straight" and refers to the upright conductor of the male; adjective.

Diagnosis. This new species can be easily recognised from all the other species by the straight conductor (Fig. 2) and the triple of lamellar structures on the distal conductor (Figs 1-6).

Description. Male (holotype). Total length 5.24; prosoma 1.96 long, 1.67 wide; opisthosoma 3.28 long, 1.80 wide. Dorsal prosoma round, yellow, with three longitudinal brown bands of different width, among them, the middle shortened to triangular band around eyes. Anterior margin of thoracic region distinctly elevated. Clypeus reddish-brown. Cheliceral lamina reduced, promargin with three teeth, retromargin with two small teeth, posterior surface of fang with 23 small denticles. Labium brown. Sternum yellow, with two brown lines each side. Opisthosoma elongate, with complex patterns dorsally and ventrally. Legs brown, femur and tibia annulated with white. Leg measurements: I-(9.95, 0.69, 10.75, 10.85, -), II-(7.35, 0.65, 7.25, 10.35, -), III 18.86 (5.42, 0.62, 4.85, 6.24, 1.73), IV 26.26 (7.62, 0.62, 7.32, 8.84, 1.88); palp 2.03 (0.85, 0.24, 0.39, 0.55), bulb 0.25 long, 0.26 wide. Male palp (Figs 1-6): tarsus with three slightly curved, serrated bristles distally and one twisty spine with tip directed towards proximally; bulb bright yellow, ovate; conductor (Fig. 2) arising distally from bulb, straight, distad; embolus (Fig. 2) arising retrolatero-proximally from bulb, slightly sigmoid, distad; embolus and conductor widely separated (distance almost equal to diameter of bulb).

Female: Unknown.

Distribution. Known only from the type locality (Fig. 47).
