Diagnosis.
The species resembles
Philoponella nasuta
(
Thorell, 1895
)
, but can be distinguished by the broad region of anterio-basal protrusion of median apophysis spur (slightly tapering in
P. nasuta
) and thinner median hematodocha (broader in
P. nasuta
); the females can be easily distinguished by the long, thin copulatory ducts (spiral in
P. nasuta
) (cf.
Figs 3–5, 6–7
with figs
3–11 in
Zhou
et al.
, 2020
).
Description.
For detailed description, see

Female
(
Figs 2, 6–7
). Total length 4.27. Prosoma 1.47 long, 1.2 wide; abdomen 2.80 long, 2.13 wide. Carapace greyish and slightly convex. Eye sizes and interdistances: AME 0.05; ALE 0.09; PME 0.06; PLE 0.03; AME-AME 0.08, AME-ALE 0.14, ALE-PLE 0.15, PME-PME 0.06, PME-PLE 0.10. Clypeus 0.08 high.

Measurement of palp and legs: palp 1.81 (0.71, 0.29, 0.35, 0.46), leg I 3.17 (1.15, 0.16, 1.12, 0.90, 0.38); II 2.49 (0.85, 0.11, 0.80, 0.39, 0.34); III 1.71 (0.72, 0.13, 0.30, 0.29, 0.27); IV 2.63 (1.12, 0.14, 0.71, 0.37, 0.29). Opisthosoma slightly broad in front and arched in the middle region, with three pairs of white spots. Epigynum with large atrium, slightly triangular anteriorly; copulatory openings present along the posterior margin on either sides of atrium; copulatory ducts long, convoluted and meandering; spermathecae small and globular (
Figs 6–7
).
Natural history.
One to several individuals of
Philoponella feroka
were found on the webs of the social spider
Stegodyphus sarasinorum
. Sometimes they were also seen on their own webs built in the gaps of
S. sarasinorum
webs. Individuals were seen capturing and consuming small prey that were trapped on the webs of
S. sarasinorum
. Adult males, females and juveniles of
P. feroka
were seen on
S. sarasinorum
webs in different habitats including paddy fields, fences, and shrubs found next to the highway in
Kerala
,
Karnataka
,
Andhra Pradesh
and
Gujarat
(
Fig. 8
).
Distribution.
Previously known only from
Kerala State
,
India
. The present study reveals its presence in three more Indian States (
Andhra Pradesh
,
Gujarat
and
Karnataka
) (
Fig. 8
) and may perhaps occur throughout the Deccan peninsula.
Justification for transfer.
The species has the following characters of the genus
Philoponella
: males with oval carapace, enlarged cephalic region (
Fig. 1
), transverse thoracic groove and well-developed conductor spike (
Figs 4–5
); females with epigynal atrium (
Fig. 6
).
