Description.
Male
(NHMSU-HA082). Total length 0.52. Carapace 0.28 long, 0.32 wide, 0.32 high. Clypeus 0.14 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.40 long, 0.32 wide, 0.36 high. Length of legs: I 1.00 (0.28, 0.12, 0.24, 0.16, 0.20); II 0.78 (0.18, 0.12, 0.18, 0.12, 0.18); III 0.58 (0.12, 0.08, 0.12, 0.10, 0.16); IV 0.80 (0.20, 0.12, 0.18, 0.12, 0.18).
Somatic characters
(Fig.
21A-C
).
Colouration
: carapace brown, sternum light brown ventrally. Legs light brown. Abdomen pale at middle, light brown laterally and ventrally.
Prosoma
: PME separated by ~ ⅓ their diameter. ALE protruded, PER slightly recurved. Clypeus concave, smooth. Sternum surface rugose, pitted, slightly plump.
Legs
: with long disto-dorsal spine on patella; 2 long dorsal spines on tibiae I and II, 1 on tibia III and IV.
Opisthosoma
: round dorsally, ovoid laterally, extended posteriorly beyond spinnerets, abdominal surface with sparse, long setae, with a postero-lateral scutum. Spinnerets light brown, surrounded by an annular plate.

Palp
(Fig.
22A
and
B
): bulb oblate, femur plump. Cymbium broad, with needle-like apical process and nodular distal one. Tegulum nearly rectangular. Median apophysis small, tubercle-like. Conductor long, wide basally, narrow mesally and distally. Embolus long, jutting out from prolateral margin of tegulum, curved upwards, extended beneath distal part of cymbium.

Female
(NHMSU-HA076). Total length 0.80. Carapace 0.32 long, 0.32 wide, 0.28 high. Clypeus 0.12 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.56 long, 0.56 wide, 0.60 high. Length of legs: I 0.84 (0.24, 0.12, 0.20, 0.12, 0.16); II 0.72 (0.18, 0.10, 0.16, 0.12, 0.16); III 0.60 (0.16, 0.10, 0.12, 0.10, 0.12); IV 0.78 (0.20, 0.10, 0.20, 0.12, 0.16).
Somatic characters
(Fig.
21D-F
).
Colouration
: prosoma and legs as in male. Abdomen pale dorsally and light grey ventrally. Carapace modified as in male. Cephalic part lower than in male.
Legs
: the spination same as in male, except tibia II lacking clasping spine.
Opisthosoma
: globose, with sparse, long setae, without posterolateral scutum. Other modifications same as in male.
Epigyne
(Fig.
22C-E
): sclerotised, cuticle weakly rugose. Epigynal posteromargin slightly protruded. Spermathecae separated by ca. 1.5 diameters. Copulatory openings adjacent. Copulatory ducts long, encircle spermathecae, forming ~
3/4
loop from posterior to anterolateral connecting with the inner middle margins of spermathecae. Fertilisation ducts short, starting at postero-lateral margin of spermathecae, extending to lateral of posterior epigynal margin.
