Etymology.
The specific name is derived from the Latin adjective
ovatus
, -
a
, -
um
, meaning “oval” referring to the shape of oval posterior parts of spermathecae.
Diagnosis.
This new species resembles
Sinopoda triangula
Liu, Li & Jäger, 2008
(
Liu
et al
. 2008
: figs 7A–H) and
S. yaanensis
sp. nov.
(
Figs 56
A–C, 57A–D, 58A–B) in having the distal embolus with triangular apophysis, stout vRTA and spermathecae bulging laterally. The male differs from
S. yaanensis
by: palp with embolic tip distinctly shorter than embolic apophysis (with same length in
S. yaanensis
); from
S. triangula
by: palp with dRTA slender, pointed distally (blunt in
S. triangula
). Female differs from
S. triangula
by: epigyne with lobal septum moderately wide (narrower in
S. triangula
); from
S. yaanensis
sp. nov.
by: vulva with ends of glandular appendages narrow (distinctly swollen in
S. yaanensis
sp. nov.
).
