Etymology. The specific name comes from the Latin clavellatus , meaning small and stick-like and referring to the shape of the embolus, adjective.
Diagnosis. The new species is similar to L. transversus sp. nov. ( Figs 19 a–c View FIGURES 19 a – i ) in general appearance, but can be separated from the latter by: the palp with 2 tibial apophyses versus 3 in L. transversus ; embolus small stick-like (tube-shaped and twisted basally in L. transversus ); epigynum without visible atrium versus with large atrium in L. transversus .
Description. Male (holotype): Total length 3.10. Prosoma 1.40 long, 1.28 wide; opisthosoma 1.80 long, 1.15 wide. Dorsal shield of prosoma yellow with a bilateral pair of longitudinal blackish brown stripes. Ocular area blackish brown, eye sizes and interdistances: ALE 0.15, PLE 0.10, AME 0.08, PME 0.05; AME-AME 0.12, AME-ALE 0.12, PME-PME 0.20, PME-PLE 0.22, MOA 0.25 long with front width 0.29 and back width 0.30. Sternum yellow. Chelicerae, gnathocoxae, labium yellowish brown. Legs yellow, distal parts of femora, tibiae and metatarsi blackish brown. Leg measurements: I 6.35 (1.95, 2.00, 1.40, 1.00), II 6.70 (2.00, 2.10, 1.50, 1.10), III 3.50 (1.10, 1.20, 0.60, 0.60), IV 3.80 (1.20, 1.30, 0.70, 0.60); formula 2, 1, 4, 3. Legs with many spines, including femora I with 3 prolateral spines, femora I–III with 4 dorsal spines, femora IV with 3 dorsal spines; tibiae I, II with 2 pairs of ventral spines and 2 prolateral, retrolateral dorsal spines, tibiae III, IV with 1 pair of ventral spines. Opisthosoma dorsum yellow, covered with longitudinal black markings; laterally yellow with a black ring; venter yellow with a pair of small stripes before spinnerets.
Palp ( Figs 3 e–g, j View FIGURES 3 a – l ). palp with VTA and RTA, VTA apically curved, RTA small digitiform, distal parts strongly sclerotized, bulb flat with a small ATA, embolus twisted and nail-shaped.
Female (one of the paratypes, HNU-PWH 06051505): Total length 3.20. Prosoma 1.40 long, 1.26 wide; opisthosoma 1.80 long, 1.50 wide. Body color lighter than in male, markings as in male. Eye sizes and interdistances: ALE 0.14, PLE 0.11, AME 0.09, PME 0.06, AME-AME 0.15, AME-ALE 0.13, PME-PME 0.21, PME-PLE 0.23; MOA 0.25 long, front width 0.30, back width 0.31. Sternum, chelicerae, gnathocoxae, labium yellow. Legs yellow with short spines, femora I with 3 prolateral spines, femora I–III with 3 (1-1-0-1) dorsal spines; tibiae I, II with 2 pairs of ventral spines, tibiae III, IV with 1 ventral spines. Leg measurements: I 4.00 (1.40, 1.40, 0.60, 0.60), II 4.20 (1.40, 1.50, 0.70, 0.60), III 2.80 (1.00, 1.00, 0.50, 0.30), IV 3.00 0 (1.00, 1.10, 0.50, 0.40); formula 2, 1, 4, 3. Opisthosoma grayish yellow with black bilateral stripes and some small white spots; the lateral with black lines; venter yellow with a pair of small blackish brown stripes before spinnerets. Epigyne-vulva ( Figs 3 h–i, k–l View FIGURES 3 a – l ). Atrium invisible; copulatory opening anterior; copulatory ducts short, spermathecae pyriform.
Variation. Total length: males 2.60–3.10 (n = 8); females 2.80–3.40 (n = 46). The female abdominal markings vary greatly in size and pigmentation: one specimen yellow with gray markings, another grayish yellow with black markings ( Figs 3 b–d View FIGURES 3 a – l ).
Distribution. China (recorded from three counties in Yunnan Province: Tengchong, Gongshan and Fugong).
