Etymology.

The specific name is derived from the Chinese pinyin dēng pào, which means 'lamp bulb’, referring to the atrium which is shaped like a light bulb; noun in apposition.

Diagnosis.

This new species is similar to C. cochlearis (Figs 1A-E, 73A, 81A, 89A) and C. yejiei sp. nov. (Figs 23A-E, 73C, 81C, 89C) in having a large atrium and long, tubular and sinuous spermathecae but can be easily distinguished by the light bulb-shaped atrium (Figs 2A-C, 73B, 81B) (vs. apple-shaped in C. cochlearis and ellipsoid in C. yejiei; Figs 1A-C, 73A, 81A, 23A-C, 73C, 81C), and by lacking a fovea (Fig. 2F) (vs. fovea present in C. cochlearis and C. yejiei; Figs 1F, 23F).

Description.

Female. Holotype (Fig. 2F, G): Total length 7.86; carapace 3.98 long, 2.51 wide; opisthosoma 3.87 long, 2.36 wide. Carapace greyish white, without pattern, fovea absent; pars cephalica slightly narrowed, cervical groove and radial grooves indistinguishable; tegument smooth, marginally clothed with dense setae. Eyes: AER slightly recurved, PER slightly wider than AER, almost straight in dorsal view. Eye sizes and interdistances: AME 0.11, ALE 0.19, PME 0.18, PLE 0.14, AME-AME 0.18, AME-ALE 0.15, PME-PME 0.44, PME-PLE 0.28, MOQL 0.52, MOQA 0.49, MOQP 0.79. Chelicerae coloured as carapace, with four teeth on promargin and three teeth on retromargin. Sternum nearly pure white, 1.99 long, 1.15 wide. Labium and endites coloured as carapace, sparsely covered with setae. Legs coloured as carapace, dorsally covered with black setae, without markings. Leg measurements: I 6.85 (2.01, 2.67, 1.33, 0.85), II 7.21 (2.19, 2.82, 1.45, 0.75), III 6.57 (2.07, 2.22, 1.64, 0.65), IV 8.94 (2.65, 2.79, 2.58, 0.93). Abdomen oval, dorsum light grey, anteriorly and marginally with conspicuous tuft of brown setae, heart mark and muscle depressions indistinct; venter coloured as dorsum, without pattern.

Epigyne (Figs 2A-E, 73B, 81B, 89B). Epigynal plate slightly longer than wide, margin not rebordered; copulatory ducts, spermathecae and bursae indistinctly visible through transparent integument. Atrium large, shaped like a tungsten lamp bulb, ca. 1.2 × longer than wide, ca. 1/3 of epigyne length. Copulatory openings indistinct, close together, located at posterior atrial margin. Copulatory ducts short and thick, heavily sclerotised, descend obliquely, then connect to spermathecae. Spermathecae long and wrinkled, consisting of tubular proximal part and sac-like distal part, with thin fertilisation ducts terminally. Bursae large, ovoid, 1.3 × longer than wide, surface translucent and wrinkled.
