Luzonacera chang Li & Li , sp. nov. ( Figs 1–2 View Figure 1 View Figure 2 , 15 View Figure 15 )
Material examined. Holotype male, Philippines, Rizal Province, Antipolo City, San Jose Village , Mystical Cave (large cave with a bird colony, 14º36.353’N, 121º12.521’E; elev. 212 m), 04 June 2015, leg. F. Ballarin & Y. Li. GoogleMaps Paratypes. 1 male, 2 females, same data as holotype ( IZCAS) GoogleMaps .
Etymology. The species name is a noun in apposition derived from the Chinese pinyin "cháng" ("long") and refers to the long embolus.
Diagnosis. Specimens of the two species of Luzonacera are very similar but can be distinguished as follows. The carapace in both sexes of L. chang Li & Li , sp. nov. has a medial rounded brown area (versus three longitudinal bands in both sexes of L. duan Li & Li , sp. nov.). The male of this species is easily recognized by the long spiral embolus (versus shorter in L. duan Li & Li , sp. nov.) and the relatively light constriction of the central part of the bulb (versus constriction more pronounced in L. duan Li & Li , sp. nov.). The female is diagnosed by the two pairs of curved, elongate, distally swollen spermathecae (versus curves of spermathecae relatively more twisted in L. duan Li & Li , sp. nov.).
Description. Male (holotype). Total length 2.72; carapace 0.85 long, 0.92 wide; abdomen 1.70 long, 0.66 wide. Carapace round, pale yellow, with rounded brown patch medially and triangular brown patch posterior to ocular area ( Fig. 2C View Figure 2 ). Fovea shallow, dark brown. Anterior margin of thoracic region distinctly elevated. Chelicerae brown with lamina, promargin with one tooth, retromargin with two small teeth, posterior surface of fang with 25 small denticles. Clypeus slanting, brown with two pale rounded areas laterally. Labium slanting, yellow. Sternum yellow, with large brown spots medially. Abdomen elongate, with complex patterns dorsally and ventrally. Legs brown; measurements: I 15.75 (4.00, 0.30, 4.10, 4.75, 2.60), II 10.97 (3.03, 0.33, 3.13, 3.40, 1.08), III 7.27 (2.13, 0.35, 2.04, 1.92, 0.83), IV 11.69 (3.44, 0.32, 3.36, 3.52, 1.05). Palp ( Figs 1 View Figure 1 A–D): tibia remarkably swollen, cymbium with distal protrusion; bulb yellow, pyriform; conductor absent; embolus a slender spiral extending subapically from bulb.
Female (paratype). Similar to male in coloration and general features but slightly larger ( Figs 2 View Figure 2 D–E). Measurements: total length 3.00; carapace 0.86 long, 0.88 wide; abdomen 1.90 long, 1.02 wide. Leg measurements: I - (3.72, 0.19, -, -, -), II 9.25 (2.56, 0.26, 2.80, 2.60, 1.03), III 9.92 (2.81, 0.28, 2.94, 3.06, 0.83), IV 6.24 (1.48, 0.31, 1.84, 1.80, 0.81). Vulva with two pairs of elongate, curved spermathecae with distal ends swollen ( Fig. 2A View Figure 2 ).
Distribution. Known only from the type locality ( Fig. 15 View Figure 15 ).
