Type material.

Holotype ♂ (IZCAS-Ar44506), China: Hainan: Lingshui County, Diaoluoshan Resort (18°43.51′N, 108°52.10′E, ca. 920 m), 20.iv.2011, Y.Y. Zhou leg. Paratypes 3♂ (IZCAS-Ar44507-44509), same data as holotype.

Etymology.

The specific name is after Mr. Fu Du (712-770), a famous ancient Chinese poet, who was crowned as Poetry Sage; noun (name) in genitive case.

Diagnosis.

Logunattus dufui sp. nov. resembles that of L. libaii sp. nov. in having similar habitus and palpal structure, but it can be easily distinguished by the embolus, which is straight and with spinous proximal apophysis (Fig. 8B ), vs. curved and without apophysis in L. libaii (Fig. 9B ).

Description.

Male (Fig. 8 ). Total length 3.32. Carapace 1.79 long, 1.28 wide. Abdomen 1.47 long, 1.10 wide. Clypeus 0.05 high. Eye sizes and inter-distances: AME 0.38, ALE 0.26, PLE 0.20, AERW 1.22, PERW 1.10, EFL 0.76. Legs: I 4.08 (1.19, 0.68, 1.00, 0.73, 0.48), II 2.93 (0.93, 0.50, 0.60, 0.55, 0.35), III 3.48 (1.13, 0.45, 0.75, 0.75, 0.40), IV 3.59 (1.08, 0.50, 0.75, 0.83, 0.43). Carapace red-brown, covered with yellow setae on face and white setae on thorax; fovea dark, longitudinal, linear. Chelicerae each with two promarginal teeth and one retromarginal tooth. Endites broadened medio-distally. Labium linguiform. Sternum longer than wide, with straight anterior margin. Legs yellow to brown, with three and two pairs of ventral spines on tibiae and metatarsi I and II, respectively. Abdomen suboval, dorsum pale to brown, covered with sparse white and brown setae, with two pairs of anterior muscle depressions and anteromedian scutum ca. half the abdominal width and length; venter yellow to pale yellow, with pair of longitudinal, dotted lines medially. Palp (Fig. 8A-C, E ). Tibia very short, with ventro-prolateral bump, and dagger-axe-shaped RTA; cymbium ~ 2 × longer than wide in ventral view, covered with dense white setae dorso-proximally; bulb elongated, with tapered, downward extending posterior lobe; embolus short and straight, forming disc and with spinous apophysis at base, and blunt apically.

Female. Unknown.

Known only from the type locality in Hainan Island, China.
