(

). All deposited in
SMF
.
Etymology
. The specific name refers to the
type
locality.
Diagnosis
. This species can be recognized by the presence of a conductor in the male palp, long embolus with distinct stylus, short slightly bent retrolateral apophysis, cymbium longer than femur, and lack of vulval diverticula. In comparison to
P. sinensis
sp. n.
, the epigyne of this species has a more procurved (convex) posterior margin (
Fig. 27
).

Paratus sinensis
sp. n.
(15–18) and
P. indicus

Epigyne of
Paratus sinensis
sp. n.
(22–26) and
P. indicus

(27–29). 22, 27—not detached epigyne, ventral; 23, 28—after maceration, ventral; 24–25—ditto, ventro-caudal; 26—ditto, caudal; 29—ditto, dorsal.
Palp as in
Figs. 8–11
,
19–21
. Femur long and thin, slightly shorter than cymbium, middle part of femur with dark ring, prolateral side with long strong spine (1/2 of femur length), dorsal side with two small terminal spines, prolateral side with one small terminal spine as long as femur diameter. Patella and tibia subequal in size, and each more than 2 times shorter than femur. Tibia with one prolateral spine, tibial apophysis small, less than tibia diameter, claw-like, slightly bent backwards. Cymbium without spines, tegulum bulbous, round in frontal view. Tegulum bears embolus and conductor, both arising near center of tegulum. Conductor membranous, weakly sclerotized, lying on embolus base. Embolus gradually tapering, with distinct stylus (

). Thick part of seminal duct makes closed loop, thin part makes a 360º loop near base of embolus.
Female. Total length 3.13–3.75. Carapace: 1.29–1.50 long, 1.23–1.37 wide, length/width 1.01–1.12, coloured as in
