Mallinella amblyrhyncha View in CoL sp. nov.

( Figs 862 View FIGURES 856–865. 856 , 891–894 View FIGURES 891–894. 891 )

Material examined. Holotype: ♂, MALAYSIA, Pahang State: 19 miles northeast of Kuala Lampur, Berlese extraction, debris along stream, 29 April 1977, leg. L.E. Watrous, AL–1872 ( AMNH) . Paratype: 1♀, same data as holotype ( AMNH) .

Diagnosis. The male of M. amblyrhyncha sp. nov. is recognized by the peculiar shape on the TA of the male palp, in combination with the strongly pronounced retrolateral margin of the male palpal tibia perpendicular to the

RTA ( Fig. 891 View FIGURES 891–894. 891 ). The female can be easily distinguished by the small spherical hump situated on the dorsal side of the spermathecae ( Fig. 892 View FIGURES 891–894. 891 ).

Etymology. The specific epithet, a noun in apposition, is derived from latinized Greek words (αµβλʋς = blunt; ρʋΎχος = snout, beak) meaning blunt beak and referring to the blunt apical fold on the TA.

Description. Male (holotype). Total length 7.34; prosoma 4.36 long, 3.20 wide. Eye sizes and interdistances: AME 0.30, ALE 0.22, PME 0.20, PLE 0.22, AME–AME 0.14, AME–ALE 0.32, PME–PME 0.24, PME–PLE 0.46; MOQ: 0.62 long, 0.50 anterior width, 0.48 posterior width. Leg measurements: I 17.78 (4.26, 5.58, 4.46, 3.46), II 14.75 (3.72, 4.64, 3.70, 2.68), III 14.84 (3.90, 4.46, 3.98, 2.48), IV 20.50 (4.96, 6.04, 6.40, 3.08).

Coloration. Carapace dark chestnut-brown. Sternum brown. Chelicerae yellowish brown. Legs yellowish brown, except for coxae whitish. Dorsum of opisthosoma dark sepia. Dorsal pattern: first and second pairs represented by pale oval spots obliquely arranged, distinctly larger than third and fourth pairs.

Palp ( Fig. 891 View FIGURES 891–894. 891 ). Retrolateral margin of palpal tibia triangular, strongly pronounced. RTA elongated, broad at base, gradually tapered towards sharply pointed apex. TA with blunt apical fold extending anteriorly; apico-prolateral fold sharply pointed, directed mesad; mesal ridge slightly elevated, occupying slightly less than half width of TA. Embolic base ovoid, aligned in oblique direction; membranous area broad, triangular, situated anteriorly. Embolus broad at base, gradually tapered towards apex, subterminally carrying small triangular denticle.

Female (paratype). Total length 6.96; prosoma 4.20 long, 3.10 wide. Eye sizes and interdistances: AME 0.30, ALE 0.20, PME 0.20, PLE 0.20, AME–AME 0.12, AME–ALE 0.30, PME–PME 0.24, PME–PLE 0.46; MOQ: 0.62 long, 0.50 anterior width, 0.48 posterior width. Leg measurements: I 16.84 (4.04, 5.28, 4.23, 3.28), II 13.97 (3.52, 4.38, 3.50, 2.54), III 14.05 (3.69, 4.22, 3.78, 2.36), IV 19.41 (4.68, 5.72, 6.06, 2.94).

Coloration. Carapace orange-brown. Sternum brown. Chelicerae yellowish brown. Dorsum of opisthosoma sepia. Dorsal pattern: first and second pairs represented by pale round spots, much larger than third and fourth pairs.

Genitalia ( Figs 862 View FIGURES 856–865. 856 , 892–894 View FIGURES 891–894. 891 ). Epigynal plate subquadrangular, longer than wide. Spermathecae in dorsal view divided into triangular base and spherical distal part visible in anterior view.

Natural history. The types were collected by sifting debris along a stream.

Distribution. Known only from the type locality on the Malay Peninsula.
