Cephalothorax length 1.71 mm., width 1.30 mm. Abdomen length 2.10 mm, width 1.30 mm. Carapace dark reddish brown, parallel-sided with relatively short white hairs, 1.30 x longer than wide, eye margins light reddish brown and whitish eye tubercles. Chelicerae brown, longer than wide with very short fang. Promargin and retromargin both toothless. Retrolateral side of chelicerae rebordered and indented subbasally, dorsum finely punctuated medially but rugose submedially. Pedipalp whitish yellow with brown embolus. Maxillae whitish yellow, longer than wide, apical margins converging and serrula black. Labium yellow brown, 2 x longer than wide, broadest medially and narrows on both ends. Sternum yellow and heart-shaped, four pairs of long bristles on apical one-fourth, apical margin straight and posterior margin blunt. <i>Eyes.</i> In two rows of four. AER more recurved and shorter than PER (0.98: 1.30 mm.). Lateral eyes on a tubercle. Eye diameter (mm): PLE (0.14)&gt; ALE (0.13)&gt; PME (0.09)&gt; AME (0.06). Eye separation (mm): PLE-PLE (0.37)&gt; PME-PME (0.34)&gt; AME-AME (0.29)&gt; AME-PME (0.23)&gt; ALE-PLE (0.21)&gt; AME-ALE (0.17). Clypeus height very wide, 7 x AME diameter. <i>Legs.</i> Uniformly whitish yellow with black spines, tarsal claws, and claw tufts. Spination in femora I and II 3 - 0-1 -0, III and IV 3 -0-0-0; tibia I 2-3 - 3 - 3, II 2 - 2 -3- 3,; metatarsi I and II 0-6 - 2 - 1, III 0-1 -0-0 and IV 0-2 -0-0. Metatarsus I with a long trichobothrium on apical one-sixth and two shorter ones located anterior and posterior of the long one. Leg formula 2134. <i>Abdomen.</i> Black with brownish tinge and covered with short white hairs, oblong with thin anterior part overhanging thoracic area, lateral margins with five white longitudinal ridges and posterior one-third lined with 9-10 transverse white ridges. Venter grayish brown marked with four light brownish yellow longitudinal bands bulging anterior of the epigastric furrow and two rounded brown spots on each side of the bulge. Spinnerets brownish yellow encircled by a white ring. Palpal organ with the seminal duct sigmoid and obliquely centered in the cymbium, pars pendula globose and apical coil of embolus around it, VTA with a blunt tip and RTA sharply pointed and needle-like. Dorsum of cymbium with two dorsal and one retrolateral spines. Tibia bears five trichobothria and four long prolateral spines. <i>FEMALE.</i> Unknown. <i>Material Examined.</i> Holotype male (coll. no. Ha 2011 - 2), CHINA, Hainan Island, Haikou, 9 April 2011, ATBarrion, JLACatindig and SCVillareal. Barrion et al. <i>Diagnostic Features.</i> Closely resembles <i>Tmarus qinlingensis</i> Song and Wang, 1994 and <i>T. piger</i> (Walckenaer, 1802) in terms of general appearance but differs from both in the (1) shape of VTA and RTA, (2) globose pars pendula, (3) median position of the sigmoid seminal duct, (4) abdominal band pattern, (5) number and position of trichobothria in metatarsus I and palpal patella, and (6) leg spination and length. <i>Etymology.</i> Patronym, in honor Dr. Shuqiang Li, for his contributions strengthening the foundation of knowledge Chinese arachnology. of in on
