Diagnosis
This species may be separated from other species of Sarax in Southeast Asia and Oceania by the following combination of characters: carapace lateral margin slightly sinuous ventral to lateral eyes (Fig. 125A); sternal platelets formed by single segments (Fig. 125B); males with secondary sexual dimorphism on the pedipalp (Fig. 125D–E); basal segment of chelicerae without tooth on retrolateral margin; cheliceral claw with four teeth; pedipalp tarsus with two small spines (Fig. 125C); leg IV basitibia with four pseudo-articles.
Etymology
Although unspecified, the species name is evidently an adjective referring to the Malaysian state of Sarawak, in which the holotype was collected.

Remarks
Sarax sarawakensis was the first species of the genus to be described. Specimens collected across Southeast Asia were initially identified as this species over the course of many years. For example, Fage (1929), followed by others (e.g., Bristowe 1952; Weygoldt 1994), erroneously reported S. sarawakensis from the Batu Caves, in peninsular Malaysia, at a time when three other species, S. buxtoni, S. rimosus and S. singaporae, were already known from the vicinity. Delle Cave (1986) cited the presence of S. sarawakensis in Singapore, probably also a misidentification (three other species, S. gravelyi sp. nov., S. rimosus and S. singaporae, are currently recorded from Singapore).
See Rahmadi et al. (2010) for a redescription and discussion on the taxonomic history of S. sarawakensis.
