Mallinella cuspidatissima Dankittipakul & Jocqué & Singtripop 2012, sp. nov.

Description

Mallinella cuspidatissima sp. nov.

(Figs 488–489, 495–496, 521–528)

Material examined. Holotype: ♂, INDONESIA, Sumatra, North Sumatra Province: Gunung Leuser NP, north part around Bohorok, rehabiliation center, primary rainforest on hills, 200 m, 19 May 1985, leaf litter, leg. Suh. Djojosudharmo (RMHN). Paratypes: 2♀, same data as holotype (RMHN). INDONESIA, Sumatra, North Sumatra Province: 2♀, Gunung Leuser NP, Ketambe, 2–4 March 1983, leaf litter, leg. Suh. Djojosudharmo (RMHN); 1♀, 19 May 1985 (RMHN).

Etymology. The superlative cuspidatissima (= most pointed) refers to the sharply pointed processes on the TA of the male palp.

Diagnosis. Mallinella cuspidatissima sp. nov. can be easily distinguished from other members of the sciophana -group by the shape of the TA in which all three processes are sharply pointed (Figs 521–523). Females can be recognized by their spermathecae with internal duct system with fewer coils (Fig. 496). The opisthosoma is entirely covered with elongated bristles. The ventral side of all legs is also clothed with long bristles (Figs 488–489).

Description. Male (holotype). Total length 6.02; prosoma 3.82 long, 2.72 wide. Eye sizes and interdistances: AME 0.18, ALE 0.12, PME 0.12, PLE 0.12, AME–AME 0.06, AME–ALE 0.20, PME–PME 0.12, PME–PLE 0.26; MOQ: 0.48 long, 0.38 anterior width, 0.36 posterior width. Leg measurements: I 15.36 (3.63, 4.85, 4.27, 2.60), II 12.88 (3.22, 3.98, 3.58, 2.06), III 11.04 (2.88, 3.40, 3.10, 1.62), IV 15.56 (3.90, 3.63, 4.96, 3.06).

Coloration (Fig. 488). Carapace uniform reddish brown. Chelicerae dark brown. Sternum dark reddish brown. Legs yellowish, except for femora yellowish brown. Opisthosoma sepia, posteriorly with white anal patch.

Palp (Figs 521–524). RTA digitiform, short and stout, gradually tapered towards bluntly pointed apex. Cymbium with broad cymbial fold, almost reaching apex. Membranous area on tegulum with distinct anterior triangular elevation. TA with three processes: triangular basal process curved outwards in ventral view, terminally bluntly pointed; meso-retrolateral process longest, with bifurcation at half its length; terminal process gradually tapered towards sharply pointed apex. Embolic base arranged in transverse position, anterior margin slightly excavated; membranous area triangular, broad. Embolus filiform, originating at 270°, gradually tapered towards pointed apex.

Female (paratype). Total length 6.13; prosoma 3.89 long, 2.76 wide. Eye sizes and interdistances: AME 0.16, ALE 0.12, PME 0.12, PLE 0.12, AME–AME 0.08, AME–ALE 0.18, PME–PME 0.12, PME–PLE 0.24; MOQ: 0.46 long, 0.38 anterior width, 0.34 posterior width. Leg measurements: I 15.64 (3.68, 4.92, 4.35, 2.65), II 13.12 (3.28, 4.06, 3.66, 2.12), III 11.04 (2.89, 3.42, 3.10, 1.62), IV 15.84 (3.96, 3.68, 5.06, 3.12).

Coloration (Fig. 489). Carapace uniform reddish brown. Chelicerae dark brown. Sternum dark reddish brown. Coxae yellowish; femora brown; other leg segments yellowish brown. Opisthosoma sepia, mottled with numerous pale round spots, posteriorly with white anal patch.

Genitalia (Figs 495–496, 526–528). Epigynal plate with deep posterior median incision, median hump triangular, posterior margin strongly rebordered. Lateral borders retracted. Insemination ducts short. Proximal part of spermathecae more or less cylindrical, apical part short, spherical, with one large internal coil.

Natural history. Mallinella cuspidatissima sp. nov. inhabits primary evergreen forests.

Distribution. Northern Sumatra.
