( Figs 52–55 ) Diagnosis. Males of this species are similar to D. umbrophila Tanikawa, 1991 by the slender embolus and curved ectobasal cymbial process. Females have wide copulatory duct. However, this new species can be distinguished by having the base and the end of the embolus with the same thickness ( vs. base of embolus significantly thicker than the end in D. umbrophila ) and the ectobasal cymbial process is directed laterally ( vs. directed ventrally in D. umbrophila ). Females can be distinguished by the terminus of the spermatheca directed laterally ( vs. directed dorsally in D. umbrophila ). Description. Male ( holotype , Fig. 54A ). Total length 2.05. Carapace 1.11 long, 0.75 wide. Abdomen 0.97 long, 0.88 wide. Dorsum of carapace yellow-brown, with grey-brown markings. Cervical groove distinct. Eye sizes and interdistances: AME 0.13, ALE 0.11, PME 0.08, PLE 0.08, AME–AME 0.05, AME–ALE 0.01, PME–PME 0, PME–PLE 0.04, ALE–PLE 0.04. Chelicerae long and strong, brown, with 3 promarginal and 4 retromarginal teeth. Gnathocoxae and labium brown. Sternum yellow-brown, with sparse black setae. Legs yellow-brown, with black pigmentation. Leg measurements: I 4.14 (1.27, 1.41, 0.98, 0.48), II 3.37 (1.07, 1.14, 0.77, 0.39), III 1.96 (0.63, 0.62, 0.39, 0.32), IV 2.25 (0.79, 0.66, 0.51, 0.29). Leg formula 1243. Abdomen oval. Both dorsum and venter brown, with black pattern. Palp ( Fig. 52 ). Embolus slender, basal part resting in groove of conductor. Conductor large. Paracymbium small and oval, with long setae. Ectobasal cymbial process hook-like, widest basally. Female (IZCAS-Ar43321, Figs 54B–C ). Total length 2.12. Carapace 1.02 long, 0.75 wide; Abdomen 0.97 long, 0.88 wide. Eye sizes and interdistances: AME 0.11, ALE 0.10, PME 0.08, PLE 0.08, AME–AME 0.04, AME–ALE 0.03, PME– PME 0, PME–PLE 0.09, ALE–PLE 0.04. Chelicerae with 2 promarginal teeth. Leg measurements: I 3.61 (1.14, 1.19, 0.84, 0.44), II 3.13 (1.02, 1.02, 0.71, 0.38), III 1.76 (0.62, 0.51, 0.37, 0.26), IV 2.22 (0.80, 0.66, 0.48, 0.28).
