Etymology: The species name is derived from Latin word “adnatus”, which means "jointed to; united with; adherent", and refers to the closely situated spermathecae; adjective.

Diagnosis: This new species is similar to D. wudangensis (Chen & Zhao 1997) and related species in having similar epigynum and palp, but can be distinguished by the small atrium in the female, and by the short distal extension of the cymbium, the short conductor, and the short embolic base in the male (Figs 16-19). The size of this new species (about 4-5 mm in body length) is much smaller than D. wudangensis , which is about 10 mm or more in body length.

Description: Female (holotype). Small sized Coelotinae , total length 4.83 (Fig. 25). Dorsal shield of prosoma 2.44 long, 1.60 wide; opisthosoma 2.39 long, 1.73 wide. AME smallest, approximately half the size of ALE; lateral eyes subequal in size, largest; PME slightly smaller than lateral eyes ( AME 0.05, ALE 0.10, PME 0.08, PLE 0.10); AME separated from each other by their diameter or slightly less, from ALE by less than AME diameter; PME separated from each other by slightly less than their diameter, from PLE by PME diameter (AME-AME 0.04, AME-ALE 0.03, PME-PME 0.07, PME-PLE 0.08, AME-PME 0.07) (Fig. 26). Chelicerae with 3 promarginal and 2 retromarginal teeth. Labium slightly longer than wide ( L / W =1.05) (Fig. 27). Epigynal teeth small, arising anterolaterally of atrium, separated by more than atrial width; atrium small, slightly wider than long, close to epigastric furrow, without distinct anterior and lateral margins; copulatory ducts long, originating posteriorly between spermathecae, extending and coiling anteriorly across middle part of spermathecae; spermathecal bases distinctly separated by about their width, stalks extending and converging anteriorly beyond spermathecal heads; spermathecal heads small, arising from middle part of spermathecae (Figs 16-17, 20-21).

Male (paratype measured). Small sized Coelotinae , total length 4.05 (Fig. 28). Dorsal shield of prosoma 2.05 long, 1.40 wide; opisthosoma 2.00 long, 1.28 wide. AME smallest, half the size of other eyes, which are subequal in size, or with ALE slightly larger ( AME 0.05, ALE 0.10, PME 0.08, PLE 0.09); anterior eyes equally separated by about half of AME diameter; posterior eyes equally separated by slightly less than their diameter (AME-AME 0.03, AME-ALE 0.03, PME-PME 0.06, PME-PLE 0.06, AME-PME 0.05) (Fig. 29). Chelicerae with 3 promarginal and 2 retromarginal teeth. Labium slightly wider than long ( L / W =0.96) (Fig. 30). Palp with a slender patellar apophysis; RTA more than half of tibial length, with a distinctly protruding distal end; lateral tibial apophysis large, close to RTA; cymbial furrow more than 2 /3 of cymbial length; conductor short, with a sharp apex, a large basal lamella, a broad dorsal edge, and a dorsal apophysis; median apophysis spoon-shaped, distinctly elongate, free-standing along anterior edge; embolus long, filiform, proximal in origin, with thread arising at 6- o’clock-position, running half an oval, extending posteriorly to distal part of tibia and anteriorly coiling beyond distal part of bulb (Figs 18-19, 22-24).

Distribution: China (Yunnan: Gongshan, Lushui) (Fig. 533)
