description: <b> <i>Arctosa danzhounensis</i> Barrion, Barrion-</b> <b>Dupo &amp; Heong, new species</b> [Figure 13 A-E] <i>MALE.</i> Holotype male, total length 4.90 mm. Cephalothorax length 2.65 mm, width 2.10 mm. Abdomen length 2.30 mm, width 1.50 mm. <i>Carapace.</i> Blackish red and sparsely covered with white hairs, 1.26 x longer than wide. Median carapace bears a reddish band slightly branching obliquely and laterally to PLE, submedian with quintuplet lateral branches radiating from fovea to posterior of fovea. Chelicerae dark maroon, subtriangular and finely striated transversely in front, narrows towards the fangs. Promargin bears two teeth, apical tooth the largest. Retromargin with two relatively small teeth. Pedipalp brownish yellow, darker towards base of cymbium and yellow towards apical one-half. Maxillae longer than wide, reddish brown with yellowish white anterior, apicolateral corner converging. Labium dark reddish brown except yellow truncate anterior margin. Sternum dark yellow brown with moderately rebordered margins, 1.16 x longer than wide. <i>Eyes</i>. In three rows of 4, 2 and 2. AER almost as long as PME row. PLE row 1.27 x wider than AER. Eye diameter (mm): PME (0.20)&gt; PLE (0.17)&gt; AME (0.13)&gt; ALE (0.10). Clypeus height narrow, approximately 0.6 AME diameter. <i>Legs</i>. Reddish brown on femora I-IV except yellow posterodorsal band on femora III-IV, patellae and tibiae annulated, metatarsi and tarsi yellow. Spination in femur I 2 -0- 0-1, III 3 -0- 0-1, IV 3 - 0-1 - 1; tibia I 2 (bristles)- 6 - 1-3, II 2 (bristles)- 4 - 2 - 2, IV 2 -6 - 2 - 2; metatarsus I 0-5 - 1-2, II 0-5 - 3 - 3, and IV 0-6 - 3 - 3. Leg formula 4123. <i>Abdomen</i>. Gray mottled yellow with an M-yellow band in the cardiac area. Venter whitish yellow clothed with gray hairs and a pair of brown rounded sigillae. Palpal organ with a long cymbium as long as combined length of tibia and patella. Median apophysis in lateral view with three arms (teeth), apical two bluntly rounded projected anteriorly and the third arm pointed posteriorly. Palea triangular. Cymbium 2 x longer than wide with two apical spines. <i>FEMALE</i>. Unknown. <i>Material Examined</i>. Holotype male (coll. No. Da 2010 - 3), CHINA, Hainan Island, Danzhou, 9-13 August 2010, ATBarrion, and SCVillareal. <i>Diagnostic Features</i>. This new species closely resembles the general body markings of <i>Arctosa hunanensis</i> Yin, Peng and Bao, 1997 but differs from the latter in (1) cheliceral dentation, (2) smaller body size (3) color pattern in the legs, carapace and abdomen, (4) leg spination,(5) shape of median apophysis, and (6) prominently triangular palea. <i>Etymology</i>. Named after the type locality.
