Etymology:
The specific name is a Latin adjective, referring to the two strong horn-like tips in retrolateral tibial apophysis (RTA) of the male palp.
Diagnosis:
Males of the new species resemble
Oxytate bhutanica
Ono, 2001
,
O. capitulata
Tang & Li, 2009
,
O. subvirens
(
Strand, 1907
)
and

in the developed retrolateral tibial apophysis (RTA), but can be clearly distinguished by two strong horn-like tips in RTA and the spine-like embolus (
