Diagnosis.
Mallinella pectinata
sp. nov.
is easily distinguished by the elongated and sharply pointed posterior ventral spines (
Figs 390–391
). The male has a peculiar TA with a grooved apex, and a well-developed prolateral extension carrying a sharply pointed terminal tooth (
Figs 396, 398
). The female is very similar to that of
M. decorata
in possessing strongly convoluted apical ducts but the spermathecae do not bend downwards (
Figs 399–401
) as in
M. decorata
.
Etymology.
The specific epithet ‘
pectinata’
is a Latin adjective meaning ‘provided with a comb’.

Description.
Male
(
holotype
). Total length 6.28; prosoma 3.14 long, 2.20 wide.

Leg measurements: I 8.62 (2.34, 3.14, 1.82, 1.30), II 7.38 (1.96, 2.66, 1.58, 1.20), III 6.24 (1.80, 1.78, 1.56, 1.00), IV 9.56 (2.50, 2.98, 2.66, 1.42).
Coloration
(

Opisthosoma dark brown. Dorsum with greatly reduced dorsal pattern: anteriorly with two pairs of faint oblong spots. Dorsal scutum brown, coriaceous, broader in front than behind, medially excavated.
Palp
(
Figs 392–394
,
396–398
). Tibia with small ventral ridge. RTA gradually tapered towards bluntly pointed apex, with distinctly broad dorsal flange. Cymbial fold relatively broad, occupying approximately 3/4 length of cymbium. TA terminally excavated; apico-promarginal ridge provided with small, triangular tooth (
Fig. 398
); meso-prolateral prong pronounced, extending mesad, carrying sharply pointed terminal tooth (
Fig. 398
); basal ridge simple. Tegular spine indistinct. Embolic base arranged in longitudinal direction, strongly excavated on both margins, tapered distally to form elongated, filiform embolus.
Female
(
