Four new troglophilous species of the genus Belisana Thorell, 1898 (Araneae, Pholcidae) from Guizhou Province, China Author Chen, Hui-Ming Author Zhu, Ming-Sheng text Zootaxa 2009 2092 58 68 journal article 10.5281/zenodo.187505 117b46d8-6e77-4c15-918e-c32282748f14 1175-5326 187505 Belisana daji sp. nov. Figs. 13–21 Holotype . Male from Zhijin Cave (26° 46΄N, 105° 54΄E, alt. 1342 m ), Minzhai town, Zhijin County, Guizhou Province, 19 January 2008 , collected by H.M. Chen (HBU) and Y.Q. Zhang (MLR). Paratypes . Two males and one female, data are same as holotype (HBU). Diagnosis. Relatively large, long-legged species with globular opisthosoma; distinguished from relatives by the shapes of procursus ( Figs. 16–18 ), bulbal projections ( Fig. 17 ) on the male, and the female genitalia (external aspect and internal structures, Figs. 15, 16 ). The new species is similar to B. douqing sp. nov. , but distinguished by the procursus with spine less than procursus tip ( Figs. 16, 17 ) and proximolateral apophysis on male chelicerae close to clypeus ( Fig. 15 ). Description. Male ( holotype ): Total length 1.8 (2.0 with clypeus), carapace width 0.73. Leg I: 26.58 (6.73 + 0.38 + 6.83 + 10.51 + 2.15), tibia II: 4.44, tibia III: 2.65, tibia IV: 3.57; tibia I L/d: 68. Habitus as in Figs. 13 and 14 . Carapace pale yellowish, light-yellow margins laterally, dark spots on middle part, thoracic furrow absent, only a darker median line ( Fig. 13 ), sternum yellowish, legs ochre-yellow, without darker rings, opisthosoma yellowish, without darker spots, with sparse hairs. Ocular area slightly elevated six eyes in two triads, distance PME-PME 0.10; diameter PME 0.075; distance PME-ALE 0.013. Clypeus unmodified. Sternum 0.55 long, 0.60 wide. Chelicerae as in Fig. 15 , with pair of curved apophyses, tips unmodified, 0.18 mm apart. Palps as in Figs. 16, 17 and 18 ; trochanter with retrolateral apophysis, femur with proximo-dorsal apophysis, procursus with spine ( Fig. 16 ) and with ventral membranous flap, bulb with hooked apophysis ( Fig. 17 ). Retrolateral trichobothrium of tibia I at 7.7%; legs without spines and curved hairs; tarsus I with ~24 pseudosegments. FIGURES 13–21. B. daji sp. nov. , male holotype and female paratype: 13, male habitus, dorsal view; 14, male habitus, lateral view; 15, male prosoma frontal view; 16, male left palp, prolateral view; 17, male left palp, dorsal view; 18, male left palp, retrolateral view; 19, male left palp trochanter and apophysis, retrolateral view; 20, female genitalia, ventral view; 21, female genitalia, dorsal view. Scale bar: 13–14, 0.4 mm; 15, 0.2 mm; 16–21, 0.1 mm. FIGURES 22–30. B. xishui sp. nov. , male holotype and female paratype: 22, male habitus, dorsal view; 23, male habitus, lateral view; 24, male prosoma frontal view; 25, male left palp, prolateral view; 26, male left palp, dorsal view; 27, male left palp, retrolateral view; 28, male left palp trochanter and apophysis, retrolateral view; 29, female genitalia, ventral view; 30, female genitalia, dorsal view. Scale bar: 22–28, 0.2 mm; 29–30, 0.1 mm. Female ( Paratypes ): In general similar to holotype . Epigynum simple externally ( Fig. 20 ), pockets 0.38 apart. Dorsal view as in Fig. 21 . Opisthosoma yellowish, with some slightly darker spots visible through cuticle dorso-laterally. Distribution: The species is known only from the type locality in Guizhou Province, China ( Fig. 12 ). Etymology. The specific name refers to the type locality. “ Daji ” was the original name of Zhijin Cave. Gender feminine. Natural history. Troglophilous, collected from entirely dark parts of one moist cave. Cave is large, arguably the best cave in China . Spiders were found on the cave walls.
