Etymology. The specific name comes from Latin word ovata (ovoid), in reference to the shape of the spermathecae.
Diagnosis. Deione ovate n. sp. is similar to D. renaria n. sp., but it can be distinguished from the latter by having the median apophysis hooked (foliiform in renaria); a much longer terminal apophysis; an epigynum without scape and the ovoid spermathecae (kidney-shaped in renaria).
Description. Male (holotype): Total length 3.70. Prosoma 1.90 long, 1.60 wide; ophisthosoma 1.80 long, 1.55 wide. Carapace longer than wide, dark brown, cervical groove obvious, cephalic region slightly elevated (Fig. 11). Eye sizes and interdistances: ALE 0.09, PLE 0.09, AME 0.15, PME 0.13; AME-AME 0.13, AME- ALE 0.30, PME-PME 0.18, PME-PLE 0.33, MOA 0.34 long with front width 0.39 and back width 0.36. Clypeus height 0.15. Sternum dark brown, cordate; chelicerae dark brown, with five promarginal and three retromarginal teeth; gnathocoxae and labium yellowish brown. Legs yellow with grayish brown alluli, with many setae and some macrosetae, coxa I hooked near distal edge, tibia II expanded, with five macrosetae distally (Fig. 12), leg measurements: I 5.40 (1.55, 2.15, 1.10, 0.60), II 5.05 (1.40, 2.05, 1.05, 0.55), III 3.30 (1.05, 1.25, 0.55, 0.45), IV 4.55 (1.35, 1.65, 1.05, 0.50), formula: I, II, IV, III. Opisthosoma longer than wide, with a pair of macrosetae anteriorly and two pairs of lateral humps posteriorly, dorsum grayish with black pattern (Fig. 11).Palpus with 2 patellar macrosetae; median apophysis hooked (Fig. 15); membranous conductor wrapped the embolus (Fig. 15); embolus slender and long (Fig. 15); terminal apophysis long, cylindrical (Figs 15, 16).
Female (paratype from GKJ026): Total length 4.90. Prosoma 2.00 long, 1.90 wide; opisthosoma 3.40 long, 2.10 wide. Coloration as in male, but lighter (Fig. 10). Eye sizes and interdistances: ALE 0.09, PLE 0.10, AME 0.14, PME 0.13; AME-AME 0.13, AME-ALE 0.35, PME-PME 0.18, PME-PLE 0.40, MOA 0.35 long with front width 0.36 and back width 0.38. Clypeus height 0.14. Leg measurements: I 4.75 (1.40, 1.80, 1.05, 0.50), II 4.40 (1.35, 1.60, 0.95, 0.50), III 2.95 (0.95, 1.05, 0.50, 0.45), IV 4.30 (1.25, 1.60, 0.95, 0.50), formula: I, II, IV, III.
