description: <b> <i>Larinia duchengcaii</i> Barrion, Barrion-Dupo &amp; Heong, new species</b> [Figure 32 A-C] <i>FEMALE.</i> Holotype female, total length 7.30 mm. Cephalothorax length 2.30 mm, width 1.40 mm. Abdomen length 4.70 mm., width 1.90 mm. <i>Carapace.</i> Yellow with brown spot anterior of the brown fovea, 1.64 x longer than broad. Chelicerae yellow, frontally robust at midlength to base. Promargin bears five –two large and three minute teeth. Retromargin with three teeth. Pedipalps yellow with long bristles, patella bears two long bristles midapically. Sternum yellow 1.4 x longer than wide, lateral margins light brown and rebordered, entire plate with at least six vertical rows of bristles, subapical area with two transverse rows of brown bristles. Apical margin concave and anterolateral corner with a light brown spot. Labium and maxillae both yellow and shape as in <i>Larinia</i>. <i>Eyes.</i> In two rows of four each. AER slightly shorter than PER, more recurved than the latter. Eye diameter (mm): AME (0.11)&gt; ALE = PME (0.10)&gt; PLE (0.09). Eye separation (mm): PME-PLE (0.29)&gt; ALE-PME (0.20)&gt; AME-ALE (0.19)&gt; AME-AME (0.13). Clypeus bears two long setae below edge of AME, height 1.3 x wider than AME diameter. Chilum hardly separated from the clypeus. <i>Legs.</i> Yellow except brownish spines and bases of spines. Spination in femur I 4 - 0-3 -0 and IV 3 - 0-1 -0; tibia I 3-6 - 3-5, II 2-6 - 4 - 4, III with three ventral bristles, and IV 1-5 - 4 - 4; metatarsus I 2-6 -0-0 and II 2-6 - 3 - 2. Retrolateral side of femur II with eight setae arranged obliquely from basolateral to apicolateral. Pedipalp spination in femur 1 -0-0-0, patella 2 -0-0-0, tibia 2 - 0-1 - 1 and tarsus with at least 10 spines. Leg formula 1423. <i>Abdomen.</i> Long and distinctly elongate, 2.47 x longer than wide, yellow with whitish tinge and five pairs of small black spots, anteriorly pointed and posteriorly rounded. Venter with a median gray band towards the spinnerets and forms an elongated U-band anteriorly. Brown spinnerets located subposteriorly. Epigynum with a long scape, 2.4 x longer than wide and lateral lobes extended outside edge of scape by as much as half scape diameter. <i>MALE.</i> Unknown. <i>Material Examined.</i> Holotype female (coll. no. Li 2010 - 1), CHINA, Hainan Island, Lingshui, 9- 13 August 2010, ATBarrion and SCVillareal. <i>Diagnostic features.</i> Closely resembles <i>L. triprovina</i> Yin, Wang, Xie and Peng, 1990 but differs from the latter in terms of (1) different leg formula and spination, (2) femur IV&gt; I&gt; II, (3) tarsus I&gt; II and IV&gt; III, (4) more acute anterior tip of abdomen, and fewer black spots in the abdomen. The new species differs from <i>L. phthisica</i> (L. Koch, 1871) in possessing a longer scape and a gray U-band in the abdominal venter. <i>Etymology.</i> Patronym, in recognition of Dr. Cai Ducheng for his assistance in the implementation of the arthropod biodiversity exploration and ecological Hainan Island, China. engineering project
