Bioacoustics of Weintrauboa yele

Diagnosis . Males of W. insularis can be distinguished from other Weintrauboa species by the shape of the ectal cymbial process ( Fig. 6 ) combined with sinuous apophysis of the first metatarsus which is less pronounced than in W. contortipes but more than in W. chikunii and W. yunnan ( Hormiga 2003: figs. 3I and 3J, labeled as “ W. chikunii ” ). The shape of the epigynal scape, with its rounded apical end ( Figs. 7 and 8 ), is diagnostic for the species. Additional morphological data. Male: See Hormiga (2003: 276) under “ W. chikunii .” Female (from Sakhalin, Krilyon Peninsula, Ulyanovka river valley). Total length 5.56. Cephalothorax 2.62 long, 2.01 wide, 1.66 high. Abdomen 2.77 long, 1.55 wide. Femur I 2.84 long. Cheliceral stridulatory striae absent. Epigynum illustrated in Figs. 7–9 . Specimens examined : RUSSIA , Sakhalin Island, Aniva Dist., Krilyon Peninsula, Ulyanovka river valley, 1–5.xi.1989 . A.M. Basarukin, 2 males , 1 female (specimens poorly preserved, partially covered with fungal hypha; deposited at California Academy of Sciences). Sakhalin Island, Juzhno-Sakhalinsk, Tourist valley, 18.x.1985 , A.M. Basarukin, 2 males (handwritten label in Russian; K. Eskov Personal Collection). JAPAN , Northern Honshu, Akia-Shi, Mt. Taiheizan, 800 m . , Akito Fukushima, 1 female (deposited at California Academy of Sciences).

Additional morphological data. Weintrauboa yele new species has been recently described and illustrated in detail by Xu & Li (2007) as W. chikunii (see Diagnosis). The description and illustrations presented here complement their description and are provided to help distinguishing W. yele new species from other species in the genus. Male ( holotype , Yele Nature Reserve). Total length 4.31. Cephalothorax 2.25 long, 1.75 wide, 1.4 high. Abdomen 2.25 long, 1.78 wide. Femur I 2.5 long. Cheliceral stridulatory striae absent. Palp illustrated in Figs. 2 and 3 . Modified setae at the base of the cymbium are present but fewer and smaller in size compared to other species in the genus (e.g., see Hormiga 2003 : fig. 5E for W. contortipes ). Female ( paratype , same locality as male). Total length 4.66. Cephalothorax 2.1 long, 1.56 wide, 1.15 high. Abdomen 3.1 long, 2.17 wide. Femur I 2.25 long. Cheliceral stridulatory striae absent. Epigynum illustrated in Figs. 1 C–D, 4 and 5. Variation. Xu & Li (2007: 499) examined 20 males and reported variation in the metatarsus morphology, ranging from having a conspicuously modified basal process to a slightly modified process.
