Mallinella sumatrana sp. nov.

( Figs 975–978 )

Material examined. Holotype: ♂, INDONESIA, Sumatra, Lampung Province: Mt. Barisan Selatan NP, road Krui – Liwa, 2 km southwest of Kubuprahu , 480–540 m, disturbed evergreen rainforest and secondary forest, 4 March 2000, leg. P.J. Schwendinger ( MHNG, Sum–00/25) . Paratype: 1♂, same data as holotype ( MHNG, Sum–00/25) .

Diagnosis. The male of this new species is distinguished from those of the closely related M. murphyorum sp. nov. by the embolus bearing a broad apical flange which is distinctly larger than in M. murphyorum sp. nov.; the embolus is also significantly broader ( Fig. 975 ).

Etymology. The specific epithet is the latinized adjective of Sumatra.

Description. Male (holotype). Total length 8.30; prosoma 5.30 long, 3.80 wide. Eye sizes and interdistances: AME 0.32, ALE 0.22, PME 0.20, PLE 0.22, AME–AME 0.16, AME–ALE 0.38, PME–PME 0.24, PME–PLE 0.58; MOQ: 0.24 long, 0.56 anterior width, 0.52 posterior width. Leg measurements: I 19.12 (4.58, 6.00, 4.80, 3.72), II 15.84 (4.00, 4.98, 3.98, 2.88), III 15.96 (4.20, 4.80, 4.28, 2.66), IV 22.00 (5.32, 6.48, 6.88, 3.30).

Coloration. Carapace and chelicerae dark chestnut-brown, slightly paler posterirorly. Sternum brown. Legs yellowish brown. Dorsum of opisthosoma dark brown. Dorsal pattern: paired anterior reniform patches followed by three pairs of round spots and transverse median band.

Palp ( Figs 975–978 ). RTA digitiform, gradually tapered anteriorly, apex sharply pointed. TA rostrated; apicoprolateral fold triangular, apex blunt; apico-prolateral process sharply pointed, directed mesad; basal tooth situated baso-retrolaterally, distally blunt. Embolic base ovoid, aligned in transverse direction, posterior margin straight; membranous area triangular, narrowed. Embolus broad proximally, gradually tapered towards apex, semi-transparent subapical flange occupying approximately 1/3 of embolic length.

Female. Unknown.

Natural history. Mallinella sumatrana sp. nov. was collected by means of sifting decomposed organic litter in disturbed evergreen rainforest and secondary forest.

Distribution. Known only from the type locality in southern Sumatra.
