description: <b> <i>Thomisus magaspangus</i> Barrion, Barrion-</b> <b>Dupo &amp; Heong, new species</b> [Figure 47 A-H] <i>MALE.</i> Holotype male, total length 3.25 mm. Cephalothorax length 1.70 mm, width 1.55 mm., width across eye tubercle 1.65 mm. Abdomen length 1.80 mm, width 2.15 mm. <i>Carapace.</i> Crab-like, 1.1 x longer than wide, reddish brown with white transverse band on the posterior eye row tubercle. Dorsum and lateral margins of carapace rough, anterolateral margins bluntly serrated and posterolaterals bear swollen peg-like spines. Chelicerae dark reddish brown, longer than wide with broad base and narrow apically. Pedipalp, maxillae and labium reddish brown. Maxillae indented midprolaterally and slightly converging apically. Labium longer than wide and narrow apically. Sternum yellowish brown, heart-shaped, margins rebordered with truncate apex and pointed posterior end. <i>Eyes.</i> In two rows with LE and PME on the transverse ridge. AER strongly recurved and longer than PER. ALE higher than AME. Eye diameter (mm.): ALE (0.12)&gt; AME (0.11)&gt; PME=PLE (0.09). Eye separation (mm.): AME-AME (0.20), AME-ALE (0.30), PME-PLE (0.40), PME-PME (0.49), PME-ALE (0.20). Clypeus height twice AME diameter. <i>Legs.</i> Dark reddish brown with yellow metatarsi and tarsi, basal third of femur II, and basal three-fourths of femur III and IV. Spination in femur I 1 - 0-4 -0 and femur II 3 -0-0-0; tibia I 2 - 2 -0-0, II 1-2 - 0-0 and III 2 -0-0-0; metatarsus I and II 0-6 -0-0. Leg formula 1243. <i>Abdomen.</i> Subquadrate with slightly convex to straight anterior margin, rounded posterior end and with straight and converging lateral one-half, broadest point just below midlength. Dorsum bears nine sigillae. Posterodorsal end with seven transversely concave ridges lined with short spines. Venter yellow brown with a rectangular sclerotized plate anterior of epigastric furrow and two longitudinal rows of sigillae (in four pairs) posterior of the furrow. Palpal organ with a distinctly downcurved base of RTA, transparent and bluntly rounded tip of ventral apophysis, and a long midventral spine in tibia. Patella with distinct tooth retrolaterally. <i>FEMALE.</i> Unknown. <i>Material Examined.</i> Holotype male (coll. No.Da 2010 - 2), CHINA, Hainan Island, Danzhou, 9-13 August 2010, ATBarrion, JLACatindig and SCVillareal. <i>Diagnostic Features.</i> <i>Thomisus magaspangus</i> Barrion, Barrion-Dupo &amp; Heong new species closely resembles the general facies of <i>T. labefactus</i> Karsch, 1881 but differs from the latter in (1) the roughness and bulbous spines in the sides of carapace, (2) strongly curved base of RTA, (3) transparent and bluntly rounded tip VTA, and (4) distinct retrolateral tooth on patella. <i>Etymology.</i> Named after the roughness (means "magaspang") of the carapace in Tagalog.
