Description
Male (Figs 3–5)
PROSOMA. 1.88 long; maximum width 1.47; minimum width 0.95. Uniformly red; slightly wrinkled, anterior region smooth. Frontal border roughly round, ca ½ of carapace length; anterior lateral borders convergent; rounded at maximum dorsal width, posterior lateral borders rounded; posterior margin narrow, rounded. Eye diameters: AME 0.12; PLE 0.11; PME 0.10; AMEs on edge of frontal border, separated from one another by ca 1 diameter, touching PLEs; PMEs ca one-quarter of diameter apart, less than ¼ of PME diameter from PLEs. Labium trapezoid-shaped, its base wider than its distal part, borders slightly curved; longer than wide at base; semi-circular notch at tip. Sternum orange, frontally darker, becoming lighter posteriorly; smooth; uniformly covered with slender black setae.
CHELICERAE. 0.84 long, ca ½ of carapace length in dorsal view; fang 0.80 long; paturon proximal dorsal and ventral side scantly covered with piligerous granulations. Cheliceral inner groove short, ca ⅓ of cheliceral length; armed with three teeth and lamina at base; B= M> D; D triangular, located roughly at centre of groove; B close to basal lamina; M close to B.
LEGS. Orange. Lengths of leg segments (leg 2 missing): fe1 1.45; pa1 0.91; ti1 1.11; me1 1.14; ta1 0.42; total 5.05; fe3 0.98; pa3 0.58; ti3 0.60; me3 0.85; ta3 0.29; total 3.30; fe4 1.33; pa4 0.78; ti4 1.01; me4 1.21; ta4 0.38; total 4.73; fe Pdp 0.88; pa Pdp 0.54; ti Pdp 0.42; ta Pdp 0.53; total 2.37; leg formula: 1>4>3. Fe3d spineless; pa3 spineless; tb3d spines arranged in one band; proximal 0; medial-proximal 0; medial-distal 0; distal 1.0.0; tb3v spineless; with one terminal spine on forward margin. Fe4d spineless; pa4 spineless; tb4d spineless; tb4v spineless; with one terminal spine at anterior border. Dorsal side of frontal legs covered with small thin grains; ventral side of pedipalp covered with setae, lacking grains. Claws with 8 teeth or less.
OPISTHOSOMA. Cream-coloured. Abdominal dorsal hairs 0.03 long; thin, slightly curved, not compressed, pointed; uniformly and thickly distributed.
PALP (FIGS 3–5). T markedly shorter than ED; external distal border straight; internal sloped backward. ED slightly bent in lateral view; internal distal border not expanded. IS and ES equally developed, fused basally; IS and ES continuous to tip, bent ventrally. ED tip straight in lateral view. C present, long; distal border rounded, smooth, slightly expanded, projected over ED external part. AC absent. LF absent. L poorly developed; external border sclerotized, not folded. LA absent. F present, distally curved. AL present, very poorly developed; proximal border in posterior view fused with DH. Base of P fused to T; slightly sloped upwards; lateral length from ⅓ to ⅖ of T width; ridge present, perpendicular to T; not expanded, upper margin smooth; not distally projected; posterior margin not folded.
