Diagnosis.
The male of this new species can be easily recognized by the apico-prolateral fold on the TA being larger than the meso-prolateral tooth, as well as the presence of a terminal flange on the embolus (
Fig. 895
). The female can be identified by the internal genitalia with short spermathecae (
Fig. 900
).
Etymology.
The specific epithet is derived from Greek (ακρος = pointed, high) and refers to the modification on the TA of the palp.

Description.
Male
(
holotype
). Total length 7.20; prosoma 4.30 long, 3.20 wide. Eye sizes and interdistances: AME 0.30, ALE 0.22, PME 0.20, PLE 0.22, AME–AME 0.12, AME–ALE 0.30, PME–PME 0.24, PME–PLE 0.46; MOQ: 0.60 long, 0.56 anterior width, 0.54 posterior width. Leg measurements: I 17.44 (4.18, 5.46, 4.38, 3.40), II 14.46 (3.64, 4.54, 3.62, 2.62), III 14.54 (3.82, 4.38, 3.90, 2.42), IV 20.10 (4.86, 5.92, 6.26, 3.02).
Coloration
. Carapace reddish brown. Sternum brown. Chelicerae yellowish brown. Legs yellowish. Dorsum of opisthosoma sepia. Dorsal pattern: anteriorly with paired reniform patches, followed by two ovoid spots, and two transverse bands. Dorsal scutum broad, ovoid, posteriorly rounded, extending about half length of opisthosoma.
Palp
(
Figs 895–897
). Retrolateral margin of palpal tibia triangular, strongly pronounced. RTA digitiform, broad at base, gradually tapered towards sharply pointed apex. TA with enlarged triangular apico-prolateral fold and smaller meso-prolateral tooth; apico-prolateral process spiniform, hidden behind apico-prolateral fold. Embolic base aligned in transverse direction; membranous area triangular, situated anteriorly. Embolus simple, broad at base, gradually tapered towards apex, terminally with semi-transparent flange.
Female
(
paratype
).
Total length 7.80; prosoma 4.30 long, 3.30 wide. Eye sizes and interdistances: AME 0.28, ALE 0.20, PME 0.20, PLE 0.20, AME–AME 0.10, AME–ALE 0.28, PME–PME 0.24, PME–PLE 0.38; MOQ: 0.58 long, 0.50 anterior width, 0.48 posterior width. Leg measurements: I 17.42 (4.18, 5.46, 4.36, 3.38), II 14.44 (3.64, 4.54, 3.62, 2.62), III 14.52 (3.80, 4.36, 3.92, 2.42), IV 20.06 (4.84, 5.90, 6.26, 3.02).
Coloration
. Similar to male
holotype
but with more elongated patches.
Genitalia
(
Figs 860
,
898–900
). Epigynal plate oblong, both margins slightly curved. Lateral borders more or less digitiform, terminally blunt, projecting inwards. Spermathecae relatively short, slightly larger than insemination ducts, triangular in dorsal view.
