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).

). 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.
