Bioacoustics of Latouchia fossoria

Notes The L. fossoria Pocock, 1901 was originally described, based on a female specimen collected from Kuatun ( 117.64 ° E , 27.73 ° N ) in Fujian Province , China . The original illustrations of this species consisted solely of the female's ocular area and sternum ( Pocock (1901) : pl. 21, figs. 2 and 2 a). Song, Zhu & Chen (1999 : figs. 16 Q – R) provided illustrations of the alleged palp of this species, which has been cited as the male description by the World Spider Catalog ( World Spider Catalog 2024 ). However, the illustrations of the alleged male L. fossoria by Song, Zhu & Chen closely match those of the palp of L. swinhoei illustrated by Pocock (see Pocock (1901) : figs. 3 and 3 a), suggesting that the former may be a copy of the latter (Fig. 4 ). Given the Song, Zhu & Chen cite the right figure numbers from Pocock and as they are not misunderstanding the numbers, we suspect that they have simply reversed the images on the plates, contrary to the intention of the text - the ones said to be (or alleged to be) L. swinhoei Pocock, 1901 (figs. 17 A-B) are actually the ' missing' images for the female holotype of L. fossoria . We believe it is important to highlight this issue, especially considering the significance of L. fossoria as the type species for Latouchia ( Decae and Caranhac 2020 ) . Therefore, the male of Latouchia fossoria should currently be considered unknown, requiring further investigation and supplementary descriptions in the future.
