Thelcticopis is a genus of huntsman spiders that occurs almost exclusively in the area India to Japan to New Guinea and Fiji. However, one species (T. pestai) occurs in Costa Rica, and another (T. humilithorax) in Congo basin, although the latter species is probably misplaced in this genus. This genus is distinguished by the abdomen narrowing behind and ending in terminal spinnerets which are borne on a tubular stalk separated at the base by a membranous ring. They are often brownish-red, the abdomen is either of uniform color or shows paired spots. However, some species are black, yellow or green.
