Five new species of the trapdoor spider genus Latouchia Pocock, 1901 (Araneae, Halonoproctidae) from China

Five new species of the trapdoor spider genus <i>Latouchia</i> Pocock, 1901 are described from southern China based on both morphological and molecular evidence: <i>L. jihe</i> <b>sp. nov.</b> (♂♀), <i>L. wufeng</i> <b>sp. nov.</b> (♂♀), <i>L. wuhan</i> <b>sp. nov.</b> (♂♀), <i>L. yinggen</i> <b>sp. nov.</b> (♂♀), and <i>L. zhangping</i> <b>sp. nov.</b> (♂♀). The male and female of <i>L. jinyun</i> Hao, Yu & Zhang, 2025 are also redescribed from specimens collected in Nanchong City, Sichuan Province, China, located over 100 km from the type locality in Chongqing Municipality. Species delimitation is supported by genetic distance analyses of the mitochondrial DNA barcode gene (cytochrome c oxidase subunit I, COI), comparing the five new species with five previously described taxa. GenBank accession codes for the five new species and <i>L. jinyun</i> are provided to facilitate future identification and taxonomic research.
