Sarax undetermined

description: Sarax sp.
Diagnosis
This undescribed species may be separated from other species of Sarax in Southeast Asia and Oceania by the following combination of characters: juveniles with distinct dark bands on carapace and legs; median and lateral eyes well developed; lateral eyes near lateral margin of carapace; carapace lateral carina present; pentasternum with four setae; ventral sacs cover well developed; male gonopod with base of LoL2 sclerotized; cheliceral claw with three or four teeth; basal segment without tooth on retrolateral surface; pedipalp femur with four dorsal spines, three ventral spines, and spine between ventral spine 1 and proximal margin; pedipalp patella with four dorsal spines, long spine between dorsal spine I and distal margin, three ventral spines, setiferous tubercle between ventral spine I and distal margin; pedipalp tibia with two setae between ventral spine and distal margin; pedipalp tarsus with two short, subequal dorsal spines, cleaning brush with 29–31 setae; tibia of leg I with 23 articles, tarsus I with 41 articles; leg IV basitibia with four pseudo-articles; trichobothrium bt situated in medial third; distitibia trichobothrium bc situated closer to bf than to sbf; sc and sf series each with six setae, proximal two trichobothria displaced from row.
