Diagnosis.
The male of
S
.
raffrayi
comb. nov.
are most similar to those of
S. murphyorum
Zonstein & Marusik, 2022
from
Kenya
as both have a slender prolateral branch of tegular apophysis, and a similarly long tegular process, but it can be distinguished by the absence of a tegular spur (
vs
. present), slightly curved distal part of retrolateral branch of tegular apophysis (
vs
. U-shaped), and inclined basal process of embolus (
vs
. directed upward) (
Fig. 3E–F
cf
.
Zonstein & Marusik 2022
: figs 11, 29).
Supplementary description of the
holotype
male (
Fig. 3A
).
After
Simon (1893)
: carapace blackish red, legs rufous chestnut, opisthosoma tawny chestnut; carapace wrinkled, covered with setae; sternum rugous; opisthosoma oblong, hirsute; body length 7.00.
Palp
(
Fig. 3E–H
). Tibia swollen (
Fig. 3H
). Cymbium narrow, with short retrobasal projection (
Fig. 3H
). Bulb ovoid, without tegular spur (
Fig. 3F, H
). Tegular apophysis (TA) stout, slightly curved, with narrow, slender, slightly curved prolateral (Tp) and retrolateral (Tr), and flat, strongly curved intermediate (Ti) branches (
Fig. 3E–F
). Dorsal tegular process (Dp) moderately long, broader at base, gradually narrowing towards apex, distally curved; embolus (E) thin and fragile, with short and inclined rod-like process (Ep) at base (
Fig. 3E
).
Female
. Unknown.
Distribution.
Known only from the
type
locality. The record of this species from
India
(
Gravely 1921
) is doubtful and refers most likely to a different species (see
Tripathi
et al.
2023
).
Justification of the transfer.
An examination of the
holotype
male of
S
.
raffrayi
revealed that
Simon (1893)
misplaced this species in
Sarascelis
Simon, 1887
as its male palp has partly fused tegular sclerites, which are completely fused and integrated in
Sarascelis
species
(
Fig. 3E–F
cf
.
Zonstein & Marusik 2022
: figs 25–26). Instead, it shows similarities with the species of
Sceliraptor
: cymbium with a retrobasal projection, stout tegular apophysis with several branches, and thin embolus with a basal process (
Fig. 3E–H
cf
.
Zonstein & Marusik 2022
: figs 8, 20, 26, 35). Based on these observations, we consider the transfer of
Sarascelis raffrayi
to
Sceliraptor
justified.
