Type material. Holotype: Male, MALAYSIA: Malaya Peninsula, Pahang State, Fraser's Hill, Mager and Abu Suradi Trail , 3°42'35.13"N, 101°44'0.96"E, 1250 m altitude, Peter Jäger leg. 18.VI.2013, disturbed primary forest, by hand, at night ( SMF) GoogleMaps .

Etymology. The specific name is derived from the Latin word "spiralis" meaning "spiral" and refers to the helical wrinkles on the distal part of the conductor; adjective.

Diagnosis. This new species can be easily recognised from all the other Althepus species by the shorter conductor (Fig. 36) and the helical wrinkles on the distal part of the conductor (Figs 35-40).

Description. Male (holotype). Total length 4.06; prosoma 1.50 long, 1.32 wide; opisthosoma 2.56 long, 1.25 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 yellow, with two oval brown patches separated medially. Cheliceral lamina reduced, promargin with three teeth, retromargin with two small teeth, posterior surface of fang with 18 small denticles. Labium brown. Sternum yellow, with two brown lines on each side. Opisthosoma elongate, with complex patterns dorsally and ventrally. Legs brown, femur and tibia annulated with white. Leg measurements: I 33.34 (8.65, 0.54, 8.85, 14.05, 1.25), II 21.52 (5.95, 0.45, 5.62, 7.82, 1.68), III 14.15 (4.15, 0.44, 3.85, 4.61, 1.10), IV missing; leg formula: 1 2 3; palp 1.62 (0.60, 0.16, 0.38, 0.48), bulb 0.25 long, 0.33 wide. Male palp (Figs 35-40): tarsus with three slightly curved, serrated bristles distally and one hooked spine with tip proximad; lateral protrusion slender; bulb yellow, sub-oval; conductor (Fig. 36) arising distally from bulb, short embolus (Fig. 36) arising distally from bulb, cambered, prolaterad; embolus and conductor slightly separated (the distance is less than one third of diameter of bulb). Female: Unknown.

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