description: <i>Ischnothyreus campanaceus</i>, new species (Fig. 1A–I) <i>Holotype. –</i> Male (IZCAS), Mountain Wuzhishan (18 <b>°</b> 49'N 109 <b>°</b> 39'E), Wuzhishan City, Hainan Island, China, coll. Y. Song, X. Han and Y. Tong, 16 Apr.2005. <b> <i>Paratypes.</i> –</b> 2 males, 4 females (IZCAS), same data as holotype. <b> <i>Diagnosis.</i> –</b> The female of the new species is similar to <i>I. linzhiensis</i> Hu, 2001 (male unknown), but can be distinguished by the distinctly short and clearly winding tube in the middle line of the postepigastric scutum, and the distinctly long abdominal dorsal scutum; the male is similar to <i>I. shillongensis</i> Tikader, 1968 (Brignoli, 1978), but can be distinguished by the modifications on base of cheliceral fang and the outgrowths on apical part of embolus. <b> <i>Description.</i> – Male.</b> Body length 1.47; carapace 0.80 length, 0.64 width; abdomen 0.70 length, 0.44 width. Sides of carapace yellowish-brown, dorsally yellow, scutum yellow, chelicerae, sternum, legs and ventral scutum light yellow. Carapace with pair of dark brown, egg-shaped patches behind eyes; dorsally with three rows of short hairs. Eyes six in two rows, quite compactly arranged; ALE slightly separated; posterior eyes in a straight row, touching each other. Base of fang with prominent processes; retromargin of fang furrow with a small tooth. Labium wider than long, endites with pointed tip. Leg I: femur with 2 prolateral and 1 small retrolateral spine, patella spineless, tibia with 4 pairs, metatarsus with 2 pairs of long ventral spines. Leg II spinatoin is similar to leg I except that femur with only one prolateral spine. Legs III and IV spineless. Measurements of legs: I 1.89 (0.56, 0.25, 0.47, 0.39, 0.22); II 1.83 (0.55, 0.24, 0.44, 0.39, 0.21); III 1.61 (0.49, 0.23, 0.26, 0.39, 0.24); IV 2.33 (0.67, 0.32, 0.49, 0.56, 0.29). Leg formula: 4&gt; 1&gt; 2&gt; 3. Dorsal scutum of abdomen oval-shaped, covering nearly entirely abdominal length. Bulbus of palp elongated, gradually tapering apically, obtusely bent before apex. Embolic part not divided into distinct lobes, bearing some membranous outgrowths. <b>Female.</b> Similar to male, but sides of carapace deeper in colour, without dorsal egg-shaped patches, base of fang unmodified, tip of endites truncated, dorsal scutum of abdomen shorter, about five-sixths abdominal length. Body length 1.52–1.57; carapace 0.70–0.78 length, 0.62–0.65 width; abdomen 0.85–0.94 length, 0.55–0.57 width. Measurements of legs: I 2.04 (0.61, 0.27, 0.54, 0.41, 0.21); II 2.04 (0.61, 0.27, 0.51, 0.43, 0.22); III 1.74 (0.49, 0.26, 0.35, 0.42, 0.22); IV 2.48 (0.69, 0.40, 0.54, 0.56, 0.29). Postepigastric scutum elongated hexagonal. A strongly winding tube visible through cuticle, originated from near the middle of epigastric sulcus and running posteriorly into the bell-shaped atrium. Internal course of tube explicit, same as the course when see from ventral view. <b> <i>Etymology.</i> –</b> Specific name comes from the Latin “ <i>campanaceus</i> = bell-shaped”, in reference to the bell-shaped atrium in female.
