DIAGNOSIS. The species is close to T. nigrus Shi, 1992 and T. hoanganus . It can be separated from T. nigrus by the black piles on the presutural area of the scutum and the subrectangular epandrium (yellow piles on scutum and epandrium slender and slightly curved in T. nigrus ); from T. hoanganus by the epandrium deeply notched at distal part (epandrium not notched distally in T. hoanganus ).
ETYMOLOGY. The species epithet is formed from the greeks words ορος, ορεος, meaning mountain, and φιλος, meaning “friend of”. It refers to the mountainous habitat where the species was collected.
