Diagnosis.
Leptonetela microdonta
is similar to
L. hangzhouensis
(
Chen
et al.
, 1984
)
, but can be distinguished by the presence of eight promarginal cheliceral teeth and five small retromarginal teeth (
Fig. 31C
); five spines on the retrolateral surface of palpal tibia, with the distal one longest (
Figs 28D
,
30B
); the fork-shaped median apophysis, and the presence of five teeth on median apophysis, with the first and fifth teeth stronger than others in the male (
Figs 28B
,
31D
).
Description.
Male:
total length 2.15 (
Fig. 28A
). Prosoma 1.12 long, 0.87 wide. Opisthosoma 1.20 long, 0.75 wide. Sternum 0.65 long, 0.50 wide. Prosoma yellow, quadrate, with a pair of setae retrolateral of PME. Median groove needle-shaped, pale brown. Cervical grooves and radial furrow distinct, pale brown. Eyes six, eye measurements: ALE 0.08, PLE 0.06, PME 0.05; ALE-PME 0.13, PLE-PLE 0.08, PLE-PME 0.06; AER 0.15, PER 0.20. Clypeus 0.12 high, slightly sloped anteriorly. Chelicera (
Fig. 31C
) yellow, with nine promarginal teeth, the basal one and distal one stronger than others, the distal three wider spaced and five small retromarginal teeth. Endites and labium yellow. Sternum and legs yellowish. Leg measurements: I 8.76 (2.37, 0.37, 2.50, 2.12, 1.40); II 7.17 (2.00, 0.35, 2.00, 1.62, 1.20); III 5.57 (1.50, 0.25, 1.50, 1.37, 0.95); IV 7.84 (2.15, 0.37, 2.25, 1.87, 1.20). Leg formula: I- IV-II-III. Femur I–IV with one long setae ventrally and basally. Tibia III IV with two short spines dorsally (0.3 and 0.6). Male palp (
Figs 28C–D
,
30A–B
): tibia with two trichobothria dorsally, one long seta and five spines retrolaterally, with the distal spine longest. Tip of the bulb (
Figs 28B
,
31D
): median apophysis fork-shaped, with five teeth distally, the first and fifth teeth much stronger than others, conductor lamellar, embolus triangular.
Female:
similar to male in coloration and general features, but with a larger body size and shorter legs. Total length 2.25 (
Figs 29A–B
). Prosoma 0.95 long, 0.87 wide. Opisthosoma 1.62 long, 1.15 wide. Sternum 0.70 long, 0.60 wide. Clypeus 0.12 high. Eye measurements: ALE 0.10, PLE 0.08, PME 0.07; ALE-PME 0.14, PLE-PLE 0.08, PLE-PME 0.06; AER 0.20, PER 0.22. Leg measurements: I 7.01 (1.87, 0.37, 2.00, 1.65, 1.12); II 5.57 (1.40, 0.37, 1.50, 1.40, 0.90); III 4.52 (1.00, 0.25, 1.15, 1.25, 0.87); IV 6.44 (1.62, 0.37, 1.80, 1.50, 1.15). Internal genitalia (
