description: <b> <i>Pardosa villarealae</i> Barrion, Barrion-Dupo &amp; Heong, new species</b> [Figure 18 A-E] <i>MALE.</i> Holotype male, total length 5.90 mm. Cephalothorax length 3.20 mm, width 2.30 mm. Abdomen length 2.80 mm, width 1.60 mm. <i>Carapace.</i> Yellow brown with broad dark brown submedian longitudinal bands running from clypeus, anterior eyes, posterior eye margins and sides of cephalic to thoracic area. Anterior end of yellow median carapace band pointed. Lateral brownish yellow carapace bands continuous with no interruptions. Anterolateral corner of carapace with a bright yellow spot. Chelicerae brown with three retromarginal and two minute promarginal teeth. Pedipalp brown to blackish brown with acutely pointed black cymbium bearing two apical spines. Maxillae yellow, twice longer than broad, prolaterals straight and moderately rounded apically. Labium light brown, slightly longer than wide, and truncate apical margin yellow. Sternum yellow with U-shaped gray band medially, slightly longer than wide. <i>Eyes.</i> In three rows of 4, 2 and 2 with row length(mm) of PLE (1.37)&gt; PME (1.00)&gt; AE (0.51). Eye diameter (mm): PME (0.40)&gt; PLE (0.34)&gt; AME (0.14)&gt; ALE (0.11). Eye separation (mm): PLE-PLE (0.77)&gt; PME-PLE (0.34)&gt; PME-PME (0.26)&gt; AME-AME (0. 10)&gt; AME-ALE (0.05). Clypeus height relatively wide, 1.4 x AME diameter. <i>Legs.</i> Yellowish brown with light gray oblique bands on femora, tibiae and metatarsi. Tibial spination in legs I-IV uniform and similar to each other except for dorsal bristles in tibia I and II 2-6 - 2 - 2. Metatarsus I with two very long bristles dorso-posteriorly and posteroprolaterally, each bristle four times longer than the metatarsal diameter. Leg fomula 4132. <i>Abdomen.</i> 1.75 x longer than wide, dull brown with blackish anterior margin, transverse submedian band and a pair of subglobose spots subposteriorly. Venter whitish yellow with a yellow V-shape sclerotized plate anterior of the epigastric furrow. Palpal organ with a 180 &amp;cir; half-coiled embolus, sigmoid apophysis bluntly rounded apically and basal tegular opening G-shaped. Conductor at 90 &amp;cir; angle from sigmoid median apophysis. Cymbium moderately slender, acute apically with two stout hooked spines and subapically enlarged. <i>FEMALE.</i> Unknown. <i>Material Examined.</i> Holotype male (coll. no. DAP 48), CHINA, Hainan Island, Dapo town, Dapo village, 25 March- 9 April 2011, ATBarrion, JLACatindig and SCVillareal. <i>Diagnostic Features.</i> This lycosid spider is similar to <i>Pardosa jambaruensis</i> Tikader, 1990 but distinguished from the latter by the (1) different structure of the palpal organ, and (2) markings on the sternum and clypeus, and median carapacial band. <i>Etymology.</i> Patronym, in recognition of Miss Sylvia C. Villareal’s support in the arthropod biodiversity exploration in Hainan Island.
