Enoplognatha angkora Barrion, Barrion-Dupo & Heong , new species [ Figure 43 A-D]

MALE. Holotype male, total length 2.14 mm. Cephalothorax length 0.94 mm., width 0.80 mm., height 0.80 mm. Abdomen length 1.20 mm., width 0.82 mm, height 0.86 mm.

Carapace. Yellow except brown eye margins, 1.18x longer than wide. Cephalic barely one-half the width of thoracic area at its widest point. Chelicerae, maxillae, labium and sternum darker yellow. Chelicerae long and slender, 4x longer than wide, frontobasal one-third swollen and promargin bears a small tooth. Maxillae longer than wide, apically converging, midpromargin and posteromargin each with a long seta twice the diameter of maxilla. Labium wider than long. Sternum almost as wide as long.

Eyes. In two rows, strongly recurved AER slightly shorter than procurved PER (0.40: 0.44mm). Eye diameter (mm.): PME (0.09)> PLE (0.08)> AME (0.07)> ALE (0.06). Eye separation (mm): AME-AME (0.09), AME-ALE (0.03), PME-PME (0.06), and PME-PLE (0.08). Clypeus height twice AME diameter.

Legs. Yellow with a black ring on anterior tip of tibia IV, without strong spines except strong bristles lining leg segments. Femur II nearly as long as femur IV. Leg formula 1423 based on femora only. Tibia, metatarsus and tarsus of leg I missing.

Barrion et al.

Palpal organ with a long 180 0 clockwise coil of the embolus and anchor-like median apophysis. Cymbium nearly globose.

FEMALE. Unknown.

Material Examined. Holotype male (coll. no. So2010-1), CHINA, Hainan Island, Panja town, Songtao Reservoir, 9-13 August 2010, ATBarrion, JLACatindig and SCVillareal.

Diagnostic Features. This new taxon resembles the general external features of Enoplognatha margarita Yaginuma, 1964 but differs from the latter in the following features (1) abdominal shape and band pattern dorsally and ventrally, (2) length of palpal tibia, (3) cheliceral dentation,and (4) structure of the palpal organ.

Etymology. Named after the anchor-like

(angkor +a) median apophysis in Tagalog.
