Fig. 1 Type material. Holotype ♂ (TRU-JS 0622), China: Hainan: Lingshui County, Diaoluoshan National Nature Reserve, 01-05.v.2021, F.E. Li leg. Etymology. The specific name is a patronym of Ms Feng'E Li, the collector of the type specimen; noun (name) in genitive case. Diagnosis. Irura liae sp. nov. closely resembles I. bidenticulata Guo, Zhang & Zhu, 2011 known from Hainan, and Hongkong of China in having a short embolus and a weakly sclerotized RTA, but it can be easily distinguished by the following characters: (1) the RTA is almost disciform in ventral view (Fig. 1A ), whereas it is elongated in I. bidenticulata ( Guo et al. 2011 : fig. 8); (2) the embolus is ~ 3/5 of the bulb length (Fig. 1A ), whereas it is ca. as long as the bulb in I. bidenticulata ( Guo et al. 2011 : fig. 8). Figure 1. Irura liae sp. nov., male holotype A palp, ventral B ditto, retrolateral C ditto, dorsal D habitus, dorsal E ditto, ventral F carapace, frontal G chelicera, posterior. Scale bars: 0.1 mm ( A-C, G ); 0.5 mm ( D-F ). Abbreviations: CA - cymbial apophysis; E - embolus; RTA - retrolateral tibial apophysis; SD - sperm duct. Description. Male (Fig. 1 ). Total length 3.89. Carapace 2.05 long, 2.17 wide. Abdomen 2.06 long, 1.96 wide. Eye sizes and inter-distances: AME 0.44, ALE 0.22, PLE 0.21, AERW 1.67, PERW 2.03, EFL 0.92. Leg measurements: I 7.56 (2.38, 1.60, 1.70, 1.13, 0.75), II 3.51 (1.25, 0.48, 0.75, 0.63, 0.40), III 3.02 (1.01, 0.48, 0.50, 0.63, 0.40), IV 3.71 (1.25, 0.63, 0.68, 0.75, 0.40). Carapace almost oval, red-brown to dark brown, covered with dense, pale setae, with dark double-humped patch medially in eye field. Chelicerae red-brown, with two promarginal teeth and one retromarginal fissidental tooth with two cusps. Endites longer than wide, with dense, dark setae on inner margins. Labium almost linguiform, paler distally, bearing dark setae at anterior edge. Sternum red-brown to dark brown, bearing pale setae of varying lengths. Legs I robust, with two pairs of macrosetae ventrally on tibiae and metatarsi, respectively; other legs pale to brown. Abdomen oval, dorsum dark brown, covered with pale, thin setae, with three pairs of muscle depressions medially, and transverse, undulate, earthy yellow streaks posteriorly, covered entirely by a large scutum; venter dark brown medially, with anterolateral pale areas. Palp (Fig. 1A-C ): tibia longer than wide, with weakly sclerotized, disciform RTA; cymbium acutely narrowed distally, with baso-retrolateral apophysis slightly curved medially and slightly pointed at distal end; bulb flat, almost round, with tapered sperm duct extending along margin; embolus filiform, strongly sclerotized, straight, originates at ~ 10:30 o'clock position on bulb, ~ 3/5 the bulb length. Female . Unknown. Distribution. Only known from the type locality on Hainan Island, China.
