Bioacoustics of Tylorida flava

Diagnosis. Females of T. flava sp. nov. are most similar with the females of T. striata , but can be distinguished from the latter by the following combination of characters: Female opisthosoma oval with caudal tubercle and without shoulder humps (opisthosoma of female T. striata triangular with paired shoulder humps and without caudal tubercle), copulatory ducts with median twist less evident and less number of wrinkles (copulatory ducts of T. striata with sharp median twist and numerous wrinkles) and nearly uniformly enlarged spermathecal bulb ( T. striata with narrow spermathecal bulb) (compare Figs 3D–F , 4E–H with Figs 13D–F , 14E–F , Yin et al. 2012 : fig. 216b–c). Females of T. flava sp. nov. can be separated from the females of T. ventralis , the common representative of the genus with high intraspecific variations by the following combination of characters: copulatory ducts large, equally wide along the entire length ( T. ventralis with short copulatory ducts with narrow distal half) and enlarged spermathecal bulb (spermathecal bulb compact in T. ventralis ) (compare Fig. 4H with Fig. 18C, F, I, L, O ; Song et al. 1999 : fig. 129D; Yin et al. 1999: fig. 216c; Zhu et al. 2003 : fig. 172G; Jäger & Praxaysombath 2009 : fig. 25).
