W. Wang , L. Zhang & M. Xu , HBUARA#2022-84 . Etymology. The specific epithet is in honor of Dr. Christa L. Deeleman-Reinhold (Ossendrecht, Netherlands ), who has contributed greatly to exploring the spider diversity in Southeast Asia, and has given us much assistance in our studies of jumping spider taxonomy. Diagnosis. Male resembles O. pakse sp. nov. and O. keyserlingi in the relatively flat tip of RTA, but it can be distinguished from O. pakse by the relatively short RTA that does not extend beyond the tip of lobe-like protrusion of tegulum ( Figs 76 , 80 ), and can be distinguished from O. keyserlingi by the more concave prolateral margin of embolic disc in ventral view ( Figs 75 , 79 ). Females can be distinguished from O. keyserlingi by the distance between atria that is three times longer than the diameter of atria ( Fig. 81 ; vs. in O. keyserlingi , the distance between atria is almost as long as the diameter of atria). Description. Male ( holotype ). Habitus as shown in Fig. 72 . Carapace length 2.63; abdomen length 2.38; measurements of eyes: AME 0.44, ALE 0.29, PME 0.08, PLE 0.24; measurements of legs: I 4.30 (1.31, 0.83, 1.00, 0.65, 0.51), II 2.93 (0.89, 0.48, 0.58, 0.54, 0.44), III 2.46 (0.17, 0.50, 0.68, 0.67, 0.44), IV 4.01 (1.28, 0.60, 0.86, 0.80, 0.47); leg formula 1432. Carapace dark, cephalon and dorsal abdomen covered by relatively dense pale-yellow setae; setae near eye lens slightly red; front edge of clypeus with one row of white setae; yellow setae on legs III–IV relatively sparse than I–II; leg I, patella II and tibia II all dark; femora II–IV, tibiae III–IV and metatarsi III–IV dark in distal half, other parts of legs light-colored. Palp ( Figs 74–76 ): palpal bulb swollen, lobe-like protrusion of tegulum relatively long, with tip pointing prolaterally; embolus slender, about S-shaped in ventral view, basal part of embolus with many shallow grooves along the extending direction of embolus; RTA bent basally, tip of RTA flat, boundary of lobe on tip of RTA not well defined. Female. Habitus as shown in Fig. 73 . Measurements of paratype : carapace length 2.43; abdomen length 2.56; measurements of eyes: AME 0.45, ALE 0.31, PME 0.09, PLE 0.23; measurements of legs: I 3.62 (1.17, 0.72, 0.78, 0.48, 0.47), II 3.35 (1.10, 0.69, 0.63, 0.46, 0.47), III 3.77 (1.31, 0.67, 0.70, 0.55, 0.54), IV 4.20 (1.35, 0.61, 0.92, 0.81, 0.51); leg formula 4132. Coloration like male but pale-yellow setae sparse, metatarsus II and tarsus II dark. Epigynum ( Fig. 77 ): atria small, far from each other with distance ca. three times longer than their diameter.Vulva ( Fig. 78 ): median part of copulatory ducts close to each other, covering inner margins of spermathecae in ventral view, bottom margin of copulatory ducts almost at same level to bottom margin of spermathecae; spermathecae subspherical, external lower margin slightly concave in ventral view. Natural history. Type specimens were collected by beating bushlands while they were subadults (penultimate); one female (MHBU-ARA-00023559) was found in cracks of handrails. Distribution. China ( Yunnan ).
