Lycosa hawigvittata Barrion, Barrion-Dupo & Heong , new species [ Figure 15 A-H]

MALE. Holotype male, total length 10.50 mm. Cephalothorax length 5.40 mm, width 3.90 mm. Abdomen length 5.10 mm, width 2.50 mm. Paratype male, total length 9.00 mm. Cephalothorax length 5.00 mm, width 3.50 mm. Abdomen length 4.50 mm, width 2.50 mm.

Carapace. 1.4x longer than wide, brown with a white median and two longitudinal sublateral bands, and white posterolaterals of carapace; cephalic area squarish laterally and distinctly narrower than thoracic area. Fovea distinctly long and deeply grooved. Chelicerae 2.2x longer than wide, dark brown frontally except orange yellow outer half towards fang, dentation with three retromarginal and two promarginal teeth. Labium wider than long, dark brown with a V-shaped yellow apical margin. Sternum uniformly yellow brown without gray band.

Eyes. In three rows of four, two and two. AER straight to slightly procurved as long as PME row but shorter than PLE row. Eye diameter (mm.): PME (0.45)> PLE (0.35)> AME (0.25)> ALE (0.20).

Legs. Uniformly brownish yellow except venter of metatarsi I and II and tarsi I and II with thick mat of white hairs. Tibia I and III subequal. Tibia IV spination 2-6-2-1, subdorsomedian with a long trichobothrium and three posterolaterally. Leg formula 4123.

Abdomen. Oblongate, 2x longer than wide, dark brown with a pair of white longitudinal bands aborted subposteriorly, venter clothed with white hairs. Spinnerets uniformly black.

Palpal organ with median apophysis slightly sigmoid and apex bluntly rounded, ratio of its width (a) over length (b) = 0.40, thin and needle-like embolus arises at 90 0 angle from conductor plate.

FEMALE. Unknown.

Material Examined. Holotype male (coll. no. DAP 11a), CHINA, Hainan Island, Dapo, Dapo Village, 25 March-9 April 2011, ATBarrion, JLACatindig and SCVillareal; paratype male (coll. no. DAP 11b), same data as holotype.

Diagnostic Features. This new species is similar to Lycosa vittata Yin, Bao and Zhang, 1995 but separated from the latter in the following characters, (1) spination and number of trichobothrium in tibia IV, (2) subequal length of tibia I and III, (3) blunt tip and sigmoid median apophysis, (4) ratio of width [a] over length [b] of median apophysis =0.40, (5) 90 0 position of thin and needle-like embolus, and (6) V-shaped yellow apical margin of the labium.

Etymology. Named after its close similarity

with L. vittata in Tagalog (hawig=like) + vittata .
