Diagnosis

The male of C. sawadee sp. nov. can be recognized by the modiFed third leg with dense spination and very short tibia, and by the characters of the palp, of which the tooth on the ventral margin of the RTA is the most conspicuous. That character is shared with C. griswoldorum , which has a shorter dorsal tibial apophysis, the shape of the RTA is triangular rather than rectangular and the abdominal pattern consists of one pale spot on a dark background.

Etymology

The species name is a noun in apposition taken from the type locality.
