Etymology.

The specific name is after Mr. Yunhu Mo, one of the collectors of the type specimens; noun (name) in genitive case.

Diagnosis.

Heliophanoides moi sp. nov. resembles that of Phintella tengchongensis Lei & Peng, 2013 in having similar palp structure, but it can be easily distinguished by the RTA, which is extending anteroventrally, and slightly less than tibia length in retrolateral view (Fig. 5C ), vs. extending anteriorly, and ~ 1.5 × longer than tibia in P. tengchongensis ( Lei and Peng 2013: fig. 8b). It also somewhat resembles that of Echinussa imerinensis Simon, 1901 in the general shape of palpal structure, but it can be easily distinguished by the tapered RTA, which does not extend ventrally beyond the bulb prolateral margin in retrolateral view (Fig. 5C ), vs. the RTA narrowest medio-posteriorly, and extends beyond the bulb prolateral margin in E. imerinensis (see the figure in Prószyński 1987).

Description.

Male (Fig. 5 ). Total length 4.70. Carapace 2.03 long, 1.73 wide. Abdomen 2.70 long, 1.24 wide. Clypeus 0.10 high. Eye sizes and inter-distances: AME 0.49, ALE 0.27, PLE 0.24, AERW 1.57, PERW 1.51, EFL 0.92. Legs: I 5.96 (1.80, 1.00, 1.58, 1.03, 0.55), II 3.70 (1.13, 0.58, 0.88, 0.68, 0.43), III 4.19 (1.30, 0.63, 0.73, 0.98, 0.55), IV 4.81 (1.40, 0.60, 1.13, 1.15, 053). Carapace red-brown, covered with sparse colourful scale-like setae and thin setae; fovea dark red, longitudinal, linear. Chelicerae red-brown, each with two promarginal teeth and one retromarginal tooth. Endites paler than chelicerae and widened distally. Labium red-brown, bearing brown setae at anterior margin. Sternum slightly longer than wide, with straight anterior margin. Legs pale yellow to red-brown, with strongest legs I bearing three and two pairs of ventral spines on the tibiae and metatarsi. Abdomen elongated, dorsum yellow to brown, with alternate yellow and brown transverse bands, covered wholly by scutum; venter pale, with longitudinal, broad, brown band medially. Palp (Fig. 5A-C ). Tibia slightly wider than long in ventral view; RTA slightly less than tibia length, extending anteroventrally, tapered to pointed tip in retrolateral view; DTA flat, almost triangular in ventral view, almost square, and extending anterodorsally in retrolateral view; cymbium ~ 2 × longer than wide, setose; bulb elongated, with sub-triangular posterior lobe, medio-retrolaterally located, lamellar tegular bump; embolus strongly sclerotized, short, curved retrolaterally with blunt tip, accompanied by lamellar process more than four times longer than wide, and with arc-shaped out-margin.

Female. Unknown.

Distribution.

Known only from the type locality in Hainan, China.
