Etymology. The specific name comes from Latin word renaria (kidney-shaped), in reference to the shape of the spermthecae.

Diagnosis. Deione renaria n. sp. is similar to D. ovata n. sp., but it can be easily distinguished from the latter by having the scape much longer and grooved (scape absent in ovata ); spermathecae kidney-shaped (ovoid in ovate ); median apophysis foliiform (hooked in ovate ); and anterior coxae having a cluster of setae in renaria (absent in ovata ).

Description. Male (holotype): Total length 3.45. Prosoma 1.70 long, 1.30 wide; ophisthosoma 2.00 long, 1.05 wide. Carapace dark brown, cervical groove obvious, cephalic region slightly elevated ( Fig. 2 ). Eye sizes and interdistances: ALE 0.08, PLE 0.09, AME 0.13, PME 0.10; AME-AME 0.11, AME-ALE 0.29, PME- PME 0.15, PME-PLE 0.33, MOA 0.38 long with front width 0.34 and back width 0.34. Sternum dark brown, chordate; chelicerae dark brow, with five promarginal and three retromarginal teeth; gnathocoxae and labium yellowish brown. Legs yellow with grayish brown annuli, with many setae and some macrosetae, coxa I hooked near distal edge, tibia II expanded with five macrosetae ( Fig. 3 ), leg measurements: I 4.35 (1.25, 1.60, 1.00, 0.50), II 3.95 (1.20, 1.50, 0.85, 0.40), III 3.05 (0.95, 1.00, 0.65, 0.45), IV 4.20 (1.25, 1.50, 0.95, 0.50). Opisthosoma yacht-shaped, pointed anteriorly, two pairs of lateral humps vertically arranged on posterior abdomen, dorsum grayish with dark pattern ( Fig. 2 ). Palpus with 2 patellar macrosetae ( Fig. 9 ); median apophysis foliiform ( Fig. 8 ); membranous conductor widely extended, curvedly; embolus slender and long; terminal apophysis small, pointed distally.

Female (paratype from YHY31): Total length 5.50. Prosoma 2.25 long, 1.50 wide; opisthosoma 3.65 long, 2.40 wide. Coloration as in male but with light colored portion before fovea ( Fig. 1 ). Eye sizes and interdistances: ALE 0.08, PLE 0.09, AME 0.13, PME 0.10; AME-AME 0.15, AME-ALE 0.48, PME-PME 0.21, PME-PLE 0.40, MOA 0.34 long with front width 0.39 and back width 0.41. Clypeus height 0.13. Leg coxae have a cluster of setae anteriorly, leg measurements: I 4.60 (1.30, 1.60, 1.15, 0.55), II 4.65 (1.30, 1.65, 1.15, 0.55), III 3.15 (0.90, 1.10, 0.65, 0.50), IV 4.80 (1.40, 1.75, 1.10, 0.55), formula: IV, II, I, III. Epigynum with grooved scape, scape originated from the anterior margin of epigynal plate, broad anteriorly, tapered to spoon-liked tip ( Figs 4, 5 ); copulatory ducts long ( Fig. 7 ); spermathecae kidney-shaped ( Figs 6, 7 ). Variation. Females, total length 5.00–6.25; males, total length 3.45–4.00.

Distribution. China (Yunnan Province).
