( Figs 777–778 View FIGURES 773–781. 773 , 794–795 View FIGURES 794–799. 794–795 , 800–804 View FIGURES 800–804. 800–801 )
Material examined. Holotype: ♂, MALAYSIA, Perak State: Maxwell Hill , 1,290–1,320 m, 7–8 January 1996,
leg. P.J. Schwendinger ( MHNG, PM2 x). Paratypes: 2♂, 3♀, same data as holotype ( MHNG, TNHM); 1♀, from the type locality, 1,200 m, 5 February 1991 , leg. P.J. Schwendinger ( MHNG) .
Diagnosis. Males are similar to those of M. angulosa sp. nov. They share the following characters of the palp: the rostrated TA with a baso-retrolateral tooth and a filiform embolus ( Fig. 800 View FIGURES 800–804. 800–801 ). In the present species the embolus is provided with a triangular subterminal flange ( Fig. 801 View FIGURES 800–804. 800–801 ). Females can be distinguished by the rather simple internal genitalia, the ducts of which consist of simple loops ( Fig. 795 View FIGURES 794–799. 794–795 ).
Etymology. The specific epithet brachyrhyncha is latinized adjective of Greek βpαχDς (= short) and ρʋΎχος (= trunk), meaning short beak which refers to the shape of the TA.
Description. Male (holotype). Total length 6.29; prosoma 3.87 long, 2.47 wide. Eye sizes and interdistances: AME 0.30, ALE 0.22, PME 0.16, PLE 0.22, AME–AME 0.10, AME–ALE 0.26, PME–PME 0.18, PME–PLE 0.40; MOQ: 0.58 long, 0.46 anterior width, 0.40 posterior width. Leg measurements: I 15.82 (3.82, 4.81, 4.44, 2.78), II 13.95 (3.58, 4.10, 3.78, 2.48), III 13.26 (3.36, 3.86, 3.88, 2.14), IV 17.78 (3.91, 5.22, 5.86, 2.78).
Coloration ( Fig. 777 View FIGURES 773–781. 773 ). Carapace orange-brown. Chelicerae brown. Sternum orange-brown. Legs yellowish, except for coxae whitish. Dorsum of opisthosoma brown. Dorsal pattern: first and second pairs forming reniform patches situated anteriorly; third to sixth pairs represented by four pairs of pale round patches, medially with three small irregular patches running longitudinally in between.
Palp ( Figs 800–801 View FIGURES 800–804. 800–801 ). Retrolateral margin of palpal tibia strongly elevated, terminally pointed. RTA broad at base, gradually tapered towards bluntly pointed apex. TA rostrated, anterior margin horizontal; apico-prolateral process slender, sharply pointed, directed posteromesad; baso-retrolateral tooth minute. Embolic base aligned in transverse direction, anterior membranous area triangular, relatively broad. Embolus linear, broader at base, tapered towards apex, subterminally with triangular semi-transparent flange.
Female (paratype). Total length 6.01; prosoma 3.70 long, 2.50 wide. Eye sizes and interdistances: AME 0.28, ALE 0.22, PME 0.18, PLE 0.22, AME–AME 0.10, AME–ALE 0.24, PME–PME 0.18, PME–PLE 0.38; MOQ: 0.56 long, 0.44 anterior width, 0.40 posterior width. Leg measurements: I 15.38 (3.66, 4.60, 4.26, 2.60), II 13.34 (3.42, 3.90, 3.62, 2.36), III 12.68 (3.22, 3.69, 3.70, 2.04), IV 17.01 (3.74, 4.98, 5.60, 2.66).
Coloration ( Fig. 778 View FIGURES 773–781. 773 ). Carapace orange-brown. Chelicerae brown. Sternum orange-brown. Legs yellowish, except for coxae yellowish whitish. Dorsum of opisthosoma sepia, mottled with numerous minute pale spots. Dorsal pattern: first and second pairs forming reniform patches situated anteriorly; third to sixth pairs represented by four pairs of pale round patches obliquely arranged, medially with three small irregular patches running longitudinally in between.
Genitalia ( Figs 794–795 View FIGURES 794–799. 794–795 , 802–804 View FIGURES 800–804. 800–801 ). Epigynal plate tongue-shaped, without anterior incision, posterior margin protruded, extending over epigastric furrow. Spermathecae broadest medially, apically rounded.
Natural history. Mallinella brachyrhyncha sp. nov. inhabits the forest floor of relatively high altitude (approximately 1,200 –1,300 m asl).
Distribution. Known only from the type locality on the Malay Peninsula.
