Sinopoda parva spec. nov.

Figs 32 a–c, 61 e–f

Type material: Holotype: male ( SD 1466 ), MALAYSIA: Pahang Province: Fraser’s Hill, Telecom loop, close to N3°43’6.3’’, E101°45’9.86’’, 1300 m, secondary forest, embankments along road, by night, by hand, 17 February 2015, P. Jäger & T. Laufs leg. ( SMF).

Etymology: The species name is derived from the Latin word “parvus, -a, -um“ meaning “small/little” and referring to the small body size of the male; adjective.

Diagnosis: Males of S. parva spec. nov. are similar to those of S. nuda , S. tanikawai Jäger & Ono, 2000 , S. longshan Yin et al., 2000 and S. derivata Jäger & Ono, 2002 in having no embolic apophysis. They can be distinguished from S. nuda by 1. smaller body size reaching 4.00 (14.90 in S. nuda ), 2. conductor with distal part narrower than proximal part in ventral view (distal part significant wider than proximal part in ventral view in S. nuda ), 3. dRTA tapering and slightly curved and vRTA tapering (dRTA slender and distinctly curved and vRTA stout in S. nuda ) and 4. brush of stiff setae at the base of the RTA absent (present in S. nuda ); from S. tanikawai by 1. spermophore curved in ventral view (nearly straight in S. tanikawai ), 2. conductor with distal part narrower than proximal part in ventral view (distal part wider than proximal part in ventral view in S. tanikawai ) and 3. vRTA long and tapering and dRTA tapering and narrow (vRTA rounded and stout and dRTA rounded and wide in S. tanikawai ); from S. longshan by 1. proximal part of embolus nearly twice the size as distal part (proximal part of embolus clearly thicker than distal part in S. longshan ), 2. conductor stout (elongated in S. longshan ), 3. tegulum not bulging laterally (bulging prolaterally in S. longshan ) 4. sperm duct curved (nearly straight in S. longshan ) and 5. dRTA longer than vRTA and vRTA tapering (dRTA nearly as long as vRTA and vRTA rounded in S. longshan ); from S. derivata by 1. spermophore curved in ventral view (straight in ventral view in S. derivata ), 2. conductor with distal part narrower than proximal part in ventral view (distal part wider than proximal part in ventral view in S. derivata ), 3. vRTA long and tapering (vRTA short and stout in S. derivata ) and 4. brush of stiff setae at the base of the RTA absent (present in S. derivata ).

Description: Male (holotype): Total length 4.00; prosoma 2.00 long, 2.00 wide, anterior width of prosoma 1.05; opisthosoma 2.00 long, 1.10 wide. Eye measurements: AME 0.11; ALE 0.18; PME 0.11; PLE 0.24; AME– AME 0.11; AME–ALE 0.02; PME–PME 0.14; PME–PLE 0.19; AME–PME 0.19; ALE–PLE 0.18; clypeus AME 0.16; clypeus ALE 0.14. Measurements of palp and legs [II: missing]: palp: 2.90 (0.90, 0.50, 0.60, 0.90); I: 8.40 (2.10, 0.95, 2.25, 2.20, 0.90); III: 8.45 (2.40, 0.90, 2.20, 2.15, 0.80); IV: 9.25 (2.50, 0.85, 2.40, 2.50, 1.00). Spination: palp: 131, 101, 2111; legs: Fe I–III 323, IV 321; Pa I&III–IV 000; Ti I 2026, III 2126, IV 2226; Mt I 1016, III–IV 3036. Cheliceral furrow with 3 anterior and 5 posterior teeth.

Colouration in ethanol: Prosoma medially yellow with conspicuous pattern, laterally brown with three yellow dots on each side, posteriorly with yellow transversal stripe. Sternum yellowish-white. Opisthosoma greyish-white with brown spots, ventrally yellowish-grey, posterior greyish-brown, laterally brown with yellow spots. Chelicerae yellow. Palps yellow; Fe distally with brown band, Pa laterally brown. Legs yellow; Fe distally and proximally with wide brown band, Pa prolaterally brown, Ti distally and proximally with pale brown band, Mt distally reddishbrown.

Palp as in diagnosis. Distal part of embolus slender. Spermophore S-shaped in ventral view. Conductor arising from 1-o’clock-position, short with wide base. dRTA longer than vRTA, slightly curved in retrolateral view, tapering and narrow in ventral view. vRTA triangular in ventral view, wide and short in retrolateral view.

Female: Unknown.

Distribution: Known only from the type locality.
