Diagnosis.
Cheliceroides longipalpis
differs from members of
Hasariini
by the presence of iridescent scales on the body (Figs
4
,
6
,
7
,
12
), the elongate male chelicera, the male palp with long and whip-like embolus originating at 2
o'clock
(left palp) and coiling around the rounded tegulum (Figs
9-11
,
16
), and the female epigynum with anterior window-like structure and relatively long and coiled copulatory ducts (Figs
14
,
15
,
17
,
18
). It is similar to
Colopsus
species in having modified and elongate male chelicera and a relatively long male palpal tibia (equal to or longer than the cymbium) (
Zabka
1985
: 210;
Logunov 2021
: 1023-1024;
Kanesharatnam and Benjamin 2021
: 54; Fig.
3
), but it can be distinguished by the S-shaped trajectory of the sperm duct on the tegulum of the male palp (vs C-shaped in
Colopsus
; compare Figs
16
,
19
), the longer embolus coiling in a circle around the tegulum (vs shorter and coiling in half a circle at most in
Colopsus
; compare Figs
16
,
19
), the absence of epigynal coupling pocket on epigynum (vs with two pockets in
Colopsus
; compare Figs
17
,
20
), and the long, coiled copulatory ducts (vs short and not obviously coiled in
Colopsus
; compare Figs
18
,
21
).
