Clubiona milingae Barrion-Dupo, Barrion & Heong , new species [ Figure 7 A-E]

MALE. Holotype male, total length 2.90 mm. Cephalothorax length 1.35 mm., width 0.90 mm. Abdomen length 1.60 mm, width 0.80 mm.

Carapace. Dark yellow with black eye margins, brown fovea and a transverse gray band anterior of fovea, 1.5x longer than wide. Three short hairs on each side of the lateral eyes and another one posterolateral of PLE present. Chelicerae dark yellow with a bulbous base seen dorsally. Promargin bears a single tooth and retromargin with three to four very minute teeth. Pedipalps yellow except dark brown sperm duct, RTA and VTA and basolateral tooth of cymbium. Maxillae yellow, 2x longer than wide and prominently concave prolaterally. Labium dark yellow, longer than wide. Sternum yellow, cup-like with straight anterior margin, broad medially and bluntly rounded posteriorly.

Eyes. In two rows of four each. AER shorter than straight PER (0.43: 0.59 mm). Eye diameter (mm): PME (0.08)> PLE (0.07)> ALE (0.06)> AME (0.05). AME closer to ALE than to each other. PME-PME most widely separated of all eyes and PME much closer to PLE.

Legs. Uniformly yellow with brownish bases of spines. Spination in femur I 1 -0-1-0, II 2 -0-1-0, III 2 -0-0-0 and IV 2 -0-1-1; tibiae I and II 0-6-0-0, III 0-1 -2-2 and IV 0-3-2-2; metatarsi I and II 0-2-0-0, III 0-3 -2-2 and IV 0-3-4-2. Tibia II as long as tibia IV. Leg formula 4213.

Abdomen. Yellow with pale transverse lines posteriorly, oblong and twice longer than wide. Vent- er pale yellow with five to six lateral longitudinal lines visible laterally. Spinnerets yellow and both pairs nearly twice longer than wide.

smaller than the outer tooth. VTA dark brown, short but plump, apically pointed and higher than ITA, bears two long bristles. Midlateral margin of RTA has a long bristle. Cymbium yellow, convex laterally with a bluntly rounded basolateral tooth.

FEMALE. Unknown.

Material Examined. Holotype male (coll. no. Yu 11), CHINA, Hainan Island, Jianfenglin , Yulingu , 31 March-1 April 2011, ATBarrion, JLACatindig and SCVillareal.

Diagnostic Features. Very closely related to Clubiona corrugata Boesenberg & Strand, 1906 in having a large RTA but differs from the latter in the following respect, (1) shape of RTA having parallel sides and bifurcate tip with unequal sizes of teeth, (2) robust VTA and ITA, (3) widely separated PME, (4) spot in the carapace, (5) leg length and spination, and (6) smaller body length.

Etymology. Patronym, in honor of Dr. Emiliana C. Bernardo fondly called by friends as "Miling", an excellent teacher in insect morphology and the mother of insect host plant resistance in the Philippines.
