Cyclosa parangdives Barrion, Barrion-Dupo & Heong , new species [ Figure 1 A-E]

MALE. Holotype male, total length 3.65mm. Cephalothorax length 1.85mm, width 1.40mm. Abdomen length 2.00mm, width 1.10mm.

Carapace. 1.32x longer than wide, dark brown with two rows of white hairs running from deep fovea to PLE, yellow band on each side of arrow-shaped fovea. Cephalic area barely half the width of thoracic area at broadest point. Chelicerae longer than wide, dark brown frontally and yellow at the rear; hidden underneath protruding cephalic area, dark brown. Pedipalps dark reddish brown with yellow patella and femur. Maxillae glossy dark reddish brown, as long as wide with convex to truncated anterior and convex retrolateral margins. Labium wider than long, dark brown and slightly yellow along rebordered apex, median area with a transversely rough groove and basal margin rebordered. Sternum heart-shaped, dark brown except yellow band on apical margin, 1.36x wider than long.

Eyes. Both eye rows subequal in length, AER more strongly recurved than PER. Eye diameter AME (0.14)>ALE (0.09)> PME (0.07)> PLE (0.06). Eye separation (mm): PME-PLE (0.17)> AME-AME (0.13)> AME-AME (0.11). Clypeus height 1AME diameter.

Legs. Brown with yellow bands, subbasal and apical yellow bands in femora I and IV, 2 subbasal in femur II and III prolaterally but reduced to single band retrolaterally; tibiae I-IV with alternating brown and yellow bands; metatarsi I-IV with a submedian and apical brown bands; tarsi I-IV with no brown band. Spination in tibia II 1-6 -0-7. Four trichobothria present in tibia II. Pedipalp about as long as tibia I. Leg formula 1243.

Abdomen. Oblong, 1.82x longer than wide, a pair of interrupted white longitudinal bands present dorsally, medially the bands extend anterolaterally and posterolaterally. Posterior end of abdomen bears three small protrusions. Subposterolateral slightly bulbous.

Palpal organ with shoe-shaped median apophysis and apically knob-like paracymbium indented subapically. Embolus and tegular apophysis almost subequal in reach.

FEMALE. Unknown.

Material Examined. Holotype male (coll. no. So 55), CHINA, Hainan Island, Panja Town, Songtao Reservoir area, 0 3 April 2011, AT Barrion, JLA Catindig, SC Villareal.

Diagnostic Features. This new species is very similar to C. dives Simon, 1877 and C. albisternis Simon,1888 , but readily separated from the two latter species by (1) abdominal shape and color pattern, (2) shoe-shape median apophysis, (3) leg coloration, and (4) spination in tibia II.

Etymology. Derived from the Tagalog word,

"parang" (like) + dives .
