14. Hippasa sinsiloides Barrion, Barrion-Dupo & Heong View in CoL , new species [ Figure 14 View Figure 14 A-G]
MALE. Holotype male, total length 6.40 mm. Cephalothorax length 2.90 mm, width 2.10 mm. Abdomen length 3.50 mm, width 1.50 mm. Paratype females, total length 6.50-8.50 mm (n=5, x = 7.52 ±0.81).
hairs,
Carapace. Yellow clothed with short gray black eye margins gray lateral margins and dorsum with at least 10 radiating thin lines converging towards the long yellow brown fovea. Cephalic distinctly narrower than thoracic area and possess a V-shaped thin gray lines forming a triangle behind posterolaterals of PLE. Chelicerae yellow brown, frontally clothed with long brown and short white hairs. Promargin and retromargin of chelicerae each with three teeth. Middle tooth the largest in promargin and apical tooth in the retromargin. Pedipalp long and yellow except brownish palpal organ. Maxillae yellow, longer than wide and broadest subapically. Labium black along basal half and yellow apically, wider than long and strongly convex laterally. Sternum dull yellow lined medially with a relatively wide longitudinal black band running from anterior margin to anterior abdominal venter where it forms an inverted U-band.
Eyes. In three rows of 4, 2 and 2 with distinct black margins. AER recurved viewed frontally, long- er than PME row (0.63: 0.57 mm) but one-fourth shorter than PLE row (0.83 mm). Eye diameter (mm): PME (0.21)> ALE=PLE (0.17)> AME (0.14). Eye separation (mm): AME-AME (0.09), AME-ALE (0.03), PME-PME (0.14), PLE-PLE (0.51), PME- PLE (0.02). ALE slightly oblique and partially divided at midlength. Clypeus height narrow, barely 0.78x AME diameter.
Legs. Yellowish brown, long and slender with long spines and bristles. Two longest dorsal bristles in tibia I about one-half length of tibia I and almost as long as longest ventral tibia I spine. Femur I and II subequal. Tibia I as long as II. Tibia I 1.7x thicker than metatarsus I and tibia II 2.14x thicker than metatarsus II. Tarsi I-II-III equally long. Long bristles in metatarsus I-II and tarsi I-II very prominent, longest bristle 3-5.6x longer than diameter of metatarsus. Spination in femur I 2 -0-2-3 and IV 3 -0-3 -0; tibia I 2 b-6-1-1, II 2 b-5-1-2, III 2-5 -2-2 and IV 2- 6 -2-2; and metatarsus I 0-4-2-2 and IV 0-8-1-1. Metatarsus IV bears six dorsolateral setae. Leg formula 4312.
Abdomen. Dorsally light yellow mottled with grayish black spots, dull yellow brown with parallel longitudinal bands on each side of cardiac area, and four pairs of circular yellow spots with a small black dot in the center just posterior of the cardiac area. Venter whitish yellow with an inverted gray brown U-band anteriorly and three pairs of black bands posteriorly. Spinnerets robust with posterior pair prominently longer than anterior pair.
Palpal organ has a hook-shaped median apophysis with a rounded tip; pars pendula strongly cleft anteromedially with right side rough; inner base of tegulum truncated; subtegulum crescent-shape; tegular apophysis with three pointed prongs and cymbium with long hairs. Ventrobasal cymbium with three very long bristles about 0.63x length of cymbium.
FEMALE. Similar to male except for larger body size and more plump abdomen. Anterior part bears a pair of white longitudinal bands on each side of cardiac area. Midposterior one-half with four pairs of yellow spots with a central dot forming four transverse rectangular closed cells. Posterior spinnerets distinctly visible dorsally with basal segment yellow brown and anterior segment black and rounded. Posterior spinnerets twice longer than the anterior spinnerets. Venter of abdomen white with grayish black epigynum and a squarish gray to black band dorsad of the epigynum.
Epigynum bears a moderately pointed to bluntly rounded tip of tongue-like scape with an oblong and tranverse copulatory openings on each side. Spermathecae oblique and bean-shaped, 2.5x longer than wide (0.14: 0.07 mm).
Material Examined. Holotype male (coll. no. So 85), CHINA, Hainan Island, Panja town, Songtao Reservoir, 3 April 2011, ATBarrion, JLACatindig and SCVillareal. Paratypes: two females (coll. no. So 86), 1 female (coll. no. So 87),and two females (coll. no. So 88),same data as holotype.
Diagnostic Features. Allied to Hippasa holmerae Thorell, 1895 but differs from the latter in the following features (1) bluntly pointed scape similar to a chisel, (2) hook-shaped median apophysis, (3) cleft apicomedian pars pendula with one rough side, (4) three prong tegular apophysis, (5) truncate inner base of tegulum, (6) femur I as long as II, (7) tibiae I-II, and equally long tarsi I-II- III, and (8) sternum median band extended to anteroventral abdomen.
Etymology. Named after the chisel-like
("sinsil" + oides) scape in Tagalog.
