Holotype female, total length 9.55 mm . Cephalothorax length 2.80 mm , width 1.90 mm . Abdomen length 6.50 mm , width 2.00 mm. Carapace. Yellow with a brown X-like fovea and black eye margins. Cephalic parallel-sided, barely 0.7 x thoracic width ( 1.37 : 1.97 mm ) and lateral margins of thoracic area lined with short brown setae. Chelicerae yellow with brown fangs and bases of teeth, 1.8 x longer than wide and swollen frontomedially. Promargin has three teeth, middle one the largest. Retromargin has four teeth smaller than those in promargin, apical tooth strongly triangular and broad basally, third tooth the smallest and basal tooth the largest. Pedipalp yellow with hairy and spinous tarsus, tarsal claws without teeth. Dorsum of pedipalp’s tibia bears three trichobothria in increasing length towards midlength, submedian trichobothrium the longest, approximately 0.75 x tibial length and 3 x longer than tibial diameter. Maxillae yellow brown, longer than wide and almost parallel-sided. Maxillae, labium, and sternum pattern as in the genus Leucauge . Labium brown in basal two-thirds and yellow in the rebordered margins. Sternum lined with black hairs converging towards the middle, apical rows of hairs distinctly longer than those in posterior one-half. Eyes. In two rows of four. AER recurved and slightly shorter than PER ( 1.04 : 1.06 mm ). Eye diameter (mm): AME ( 0.13 )> ALE=PME=PLE ( 0.11 ). Clypeus height 1.45 x AME diameter. Eye separation (mm): AME-ALE ( 0.29 )> PME-PLE ( 0.26 )> PME-PME ( 0.14 )> AME-AME ( 0.11 ). Median ocular quad wider behind than in front ( 0.33 : 0.39 mm ) and posterior width slightly shorter than height ( 0.40 mm ). Legs. Yellow except black anterior tip of segments, long and slender. Spination in femur I 0- 0-6 - 3 , II 1 - 0-4 - 3 and IV 3 - 0-2 - 2 ; tibia I 2 - 0-3 - 3 , II and IV 2 - 0-2 - 2 ; metatarsus I 1 - 0-1 - 2 , II with 1 - 0-1 - 1 and IV 1 - 1 -2- 2 .

Material Examined . Holotype female (coll. no. S093), CHINA , Hainan Island, Panja town, Songtao Reservoir, 3 April 2011 , ATBarrion, JLA- Catindig and SCVillareal. Paratypes : four females (coll. nos. S095-S- 97 ) and one subadult female (coll. no. S094), same data as for holotype . Etymology. Named derived from amalgamated Tagalog expression "talagang meaning really different. the iba" 34 .
