Two new species of Araneus Clerck, 1757 (Araneae, Araneidae) and first description of A. wulongensis male from China Author Liu, Ping Author Irfan, Muhammad Author Yang, Su-Fang Author Peng, Xian-Jin text ZooKeys 2019 886 61 77 http://dx.doi.org/10.3897/zookeys.886.31163 journal article http://dx.doi.org/10.3897/zookeys.886.31163 1313-2970-886-61 512BB3C93B884A34977061F3845770BA E3765D62384D5A6B9CB55987C04EA58E Araneus digitatus sp. nov. Figs 6 , 7 , 8 , 12 Type material. Holotype, ♂, China, Hubei Province : Badong County, Yanduhe Town, Songziyuan Village, Wagang Creek, 31.35067N , 110.42625E , 1340 m, 28.04.2016, W. Liu, C. Zeng and T. Tian leg (20160428). Paratypes: 1♀, same data as holotype (20160428); 1♂, same locality, Tiansheng Valley, 31.35279N , 110.39937E , 1836 m, 27.04.2016, W. Liu et al. leg. (20160427). Etymology. The specific name is derived from the Latin adjective digitatus (finger-shaped), referring to the finger-shaped terminal apophysis. Diagnosis. The new species resembles A. ryukyuanus Tanikawa, 2001 ( Tanikawa 2001 : figs 5-8, 19-21), but can be distinguished by: 1) embolus with pointed and straight tip in A. digitatus sp. nov. vs with blunt and bended tip in A. ryukyuanus ; 2) tip of scape about 2/3 of epigyne width in ventral view in A. digitatus sp. nov. vs only 1/3 of the width of epigyne in A. ryukyuanus ; 3) epignal lateral plates expanded laterally in A. digitatus sp. nov. vs tube-shaped in A. ryukyuanus ; 4) abdomen with dark brown folium in both sexes in A. digitatus sp. nov. vs female abdomen mid-dorsally with broad, yellowish band and black in male in A. ryukyuanus . The new species also resembles A. zhaoi Zhang & Zhang, 2002 ( Zhang and Zhang 2002 : fig. 1), but can be distinguished by: 1) embolus hook-shaped, distal part slender in A. digitatus sp. nov. vs sickle-shaped, distal part not slender in A. zhaoi ; 2) tegular rim almost straight in ventral view in A. digitatus sp. nov. vs waved in A. zhaoi ; 3) copulatory openings distinct in ventral view in A. digitatus sp. nov. vs indistinct in A. zhaoi .
