Dupo & Heong, new species [ Figure 5 A-E]

FEMALE. Holotype female, total length 6.70 mm. Cephalothorax length 2.40 mm., width 1.75 mm. Abdomen length 4.20 mm, width 2.50 mm.

Carapace. Dark yellow with black eye margins, brown fovea and a light brown longitudinal line anterior of fovea, 1.37x longer than wide. Chelicerae concolorous with carapace. Promargin bears four teeth, subbasal tooth the largest. Retromargin has three minute and seven very minute teeth. Midventral half of chelicerae with eight long hairs arranged obliquely. Pedipalps yellow except yellow brown spines, tibia and tarsus. Maxillae yellow to dark yellow, 2.28x longer than wide, almost parallel-sided with rounded apex. Labium dark yellow, 1.28x longer than wide, lateral margins straight and and apical yellow margin cleft. Sternum yellow, 1.4x longer than wide, apical margin straight and obliquely cut anterolaterally opposite coxa I. Posterior tip of sternum protruded and truncately tongue-like.

Eyes. In two rows with slightly recurved AER shorter than straight PER (0.49: 0.73 mm). Eye diameter (mm): ALE=PLE (0.14)> PME (0.13)> AME (0.06). Eye separation (mm): PME-PME (0.14)> PME-PLE (0.11)> ALE-PLE (0.09)> AME – AME = AME-ALE (0.03). Clypeus height as long as one AME diameter.

Legs. Yellow with brown bases of spines, moderately slender. Spination in femur I 3 -0-2-2, II 3 -0-1-2, III 2 -0-2-2 and IV 3 -0-1-1; tibia I 2 b-6-2-2, II 2 b-4-3-3 and IV 2-3 -2-2; and metatarsus I 0-4-3-1, II 0-4-3-3 and IV 0-6-3-3. Leg formula 1423.

Abdomen. Yellow mottled with gray brown spots, medially with two pairs of gray brown subrectangular spots. Venter dull yellow with yellow spinnerets.

Epigynum with a distinctly convex hood. Basal spermathecae close to the posterior epigynal margin and transversely oblong. Copulatory tube long, coiled anteriorly from base and entwined medially. A broad transparent membrane present on each side of the copulatory tube.

MALE. Unknown.

Material Examined. Holotype female (coll. No. Ha2011 -7), CHINA, Hainan Island, Haiko, 9 April 2011, ATBarrion, JLACatindig and SCVillareal.

Diagnostic Features. Very similar to C. filicata Cambridge, 1874 but differs from the latter in the following characters, (1) promargin with four teeth and retromargin bears 10 minute to very minute teeth, (2) spotted abdominal markings, (3) leg formula, and (4) blunt posterior tip of abdomen.

MALE. Unknown.

Material Examined. Holotype female (coll. no. Ha2011 -7), CHINA, Hainan Island, Haiko, 9 April 2011, ATBarrion, JLACatindig and SCVillareal.

Diagnostic Features. Very similar to the external features of C. filicata Cambridge, 1874 but differs from the latter in the following characters, (1) promargin with four teeth and retromargin bears 10 minute to very minute teeth, (2) spotted abdominal markings, (3) leg formula, and (4) blunt posterior tip of abdomen.

Etymology. Derived from the spotted ("batikan" + oides) gray brown markings in the abdominal dorsum in Tagalog.
