Mallinella callicera View in CoL sp. nov.
( Figs 161 View FIGURES 156–161. 156 , 194–197 View FIGURES 194–201. 194–197 )
Material examined. Holotype: ♂, THAILAND, Kampaeng Phet Province: Mae Wong NP, lowland evergreen forest near waterfall, 12 August 2006, leg. P. Dankittipakul ( MHNG) . Paratypes: 5♂, same data as holotype ( MHNG, TNHM) .
Diagnosis. Mallinella callicera sp. nov. shares with M. cryptocera sp. nov. the pronounced triangular elevation on retrolateral side of the male palpal tibia and the filiform embolus ( Figs 194–197 View FIGURES 194–201. 194–197 ). It can be easily distinguished from the latter species by the possession of a large triangular fold on the prolateral side of TA. This is the largest species among members of the cryptocera -group.
Etymology. The specific epithet is a latinized combination of the Greek words (καλλος = beauty; κƐρας = horn, antler) meaning ‘beautiful horn’. Noun in apposition.
Description. Male (holotype). Total length 7.37; prosoma 3.63 long, 2.97 wide; opisthosoma 3.74 long, 2.75 wide. Eye sizes and interdistances: AME 0.13, ALE 0.14, PME 0.15, PLE 0.14, AME–AME 0.14, AME–ALE 0.24, PME–PME 0.18, PME–PLE 0.32; MOQ: 0.50 long, 0.36 anterior width, 0.46 posterior width. Leg measurements: I 10.01 (2.75, 3.08, 2.20, 1.98), II 9.79 (2.53, 3.08, 2.42, 1.76), III 9.68 (2.64, 2.97, 2.53, 1.54), IV 11.79 (2.75, 3.85, 3.63, 1.56).
Coloration ( Fig. 161 View FIGURES 156–161. 156 ). Carapace uniform dark brown. Sternum reddish brown. Chelicerae brown. Coxae whitish, other segments yellowish, proximal part of femora and tibiae slightly darker. Dorsum of opisthosoma dark brown, mottled with minute pale spots. Dorsal pattern: first and second pairs fused, forming reniform patches; third to fifth pairs represented by paired oblong bands; sixth pair by short transverse band. Dorsal scutum brown, edge sharply defined.
Palp ( Figs 194–197 View FIGURES 194–201. 194–197 ). Palpal tibia with strongly pronounced triangular retrolateral elevation perpendicular to RTA. RTA digitiform, relatively long and narrowed, gradually tapered towards blunt apex. TA distinctive, anteriorly with short, sharply pointed apico-prolateral fold and elevated apical ridge; apico-prolateral process absent; meso-prolateral fold triangular, distinctly large. Embolus filiform, originating at 270°.
Female. Unknown.
Natural history. Types of M. callicera sp. nov. were found in a remnant patch of evergreen lowland forest nourished by streams and waterfalls.
