Etymology.
The specific epithet is a noun in apposition, referring to the harvest festival known as ‘the 100 drums festival’ among the Garo community of
Meghalaya
. This festival is held in honour of Saljong, the Sun-God of fertility, marking the end of a period of toil, and indicating the beginning of the winter season.
Diagnosis.
The female of
S
.
wangala
sp. nov.
is most similar to those of
S. benjamini
Zonstein & Marusik, 2023
, the only known Indian congener, as both have well developed median, unpaired scutum, and long connective stalks of grape-shaped glands with single loop, but it can be distinguished by closely spaced dot-like scuta (
vs
. widely spaced), presence of stripe-like lateral scuta (
vs
. absent), and medially placed and closely spaced anterior globular parts of receptacles (
vs
. basolaterally placed and widely spaced) (cf.
Figs 1F–H
,
2A–B
and
Zonstein & Marusik, 2023
: figs 17, 21).
Description.
Female
(
holotype
). Habitus and somatic structures as in
Fig. 1A–E
. Carapace, clypeus, sternum, mouthparts and legs scarlet red, with orange shades on legs II–IV and spinnerets; opisthosoma creamy white. Cheliceral furrow with 8–10 peg teeth; promargin lacks true tooth, retromargin with two (
Fig. 1E
, arrows). Opisthosoma ovate (
Fig. 1A, C
); epigastric scutum nearly circular (
Fig. 1B
); venter with seven thin scuta lying near epigastric scutum, one pair of lateral, one pair of stripe-like and one pair of dot-like lateral, and one patch-like median, unpaired and posteriorly with pair of dot-like scuta on both sides of tracheal spiracle (
Fig. 1B
). Body length 7.36. Carapace 2.66 long, 2.09 wide. Opisthosoma 4.69 long, 3.08 wide. Eye sizes and interdistances: ALE 0.07, AME 0.13, PLE 0.08, PME 0.08; AME–ALE 0.14, AME–AME 0.12, AME–PME 0.10, PME–PLE 0.19, PME–PME 0.18. Clypeus height at ALEs 0.48, at AMEs 0.47. Chelicerae 1.06 long. Measurements of palp and legs: palp 1.61 [0.50, 0.19, 0.38, 0.54], I 6.42 [2.02, 1.63, 1.31, 0.70, 0.76], II 5.88 [1.75, 0.89, 1.62, 0.93, 0.69], III 5.00 [1.63, 0.69, 1.15, 1.05, 0.48], IV 8.38 [2.24, 0.94, 1.73, 1.78, 1.69].
Copulatory organs
as in
Figs 1F–H
,
2A–B
. Epigastric scutum moderately sclerotised, with internally thick posterior edge having median concavity (
Figs 1F–G
,
2A
). Median transverse plate (MTP) of epigastric scutum sclerotised, remained internal to epigastric scutum (
Fig. 2B
). Receptacles (Re) long, sclerotised, spiralled remained contiguous posteriorly, whereas medially placed blunt anterior parts lying close to each other, but not contiguous (
Figs 1H
,
2B
). Grape-shaped glands (GG) lying adjacent to anterior parts, with long thread-like twisted connective stalks (
Figs 1H
,
2B
).
Male
. Unknown.
Distribution.
Known only from the
type
locality.
Note.
With the description of this species, the known palpimanid fauna in
India
is increased from seven to eight species belonging to four genera (
Tripathi
et al.
2023
;
Zonstein & Marusik 2023
).
