“…A total of six recognized species occur on the Taiwan‐Ryukyu Archipelago. The Macrothele taiwanensis species group includes M. amamiensis (Amami Island), M. yaginumai (Ishigaki and Iriomote) and M. taiwanensis (Taiwan) (Shimojana & Haupt, ). These ground‐dwelling spiders have very limited dispersal capacities, and only adult males are migratory over short distances in association with reproductive effort.…”

“…These ground‐dwelling spiders have very limited dispersal capacities, and only adult males are migratory over short distances in association with reproductive effort. Morphologically, they are extremely conservative and are only identifiable by subtle differences in male genitalia (Shimojana & Haupt, ). Their multi‐island distribution and limited migratory abilities make the M. taiwanensis species group an ideal study system with which to test the impacts of palaeo‐geographical barriers on processes of evolutionary diversification in the Taiwan‐Ryukyu Archipelago.…”

Aim We tested the competing hypotheses concerning the relative importance of Pleistocene versus Miocene-Pliocene geological events for the formation of endemism in an Asian archipelago using the Macrothele taiwanensis (Hexathelidae) species group.Location Taiwan-Ryukyu Archipelago.Methods We estimated phylogenetic trees from cytochrome oxidase I subunit (COI) and 16S rRNA (16S) gene regions and employed Bayesian ancestral range reconstructions to investigate previously debated models of lineage diversification in the Taiwan-Ryukyu Archipelago. To evaluate alternative geological timeframes for their importance in shaping the genetic structure of funnel web spiders, we used five time calibration schemes to estimate timing of divergence, infer ancestral distributions, and to reconstruct historical demographic changes in each lineage. We tested taxonomic boundaries with two species delimitation procedures.Results Our results indicate a north-to-south isolation sequence of the M. taiwanensis group: the Amami lineage diverged first, then Yaeyama, and finally the Taiwanese lineages. Divergence time estimation and population demographic change analyses indicate that Pleistocene climate fluctuations minimally impacted the genetic structure of these spiders. Instead, estimated divergence events correspond to Miocene-Pliocene geological events, strongly supporting a much older timeframe for diversification. The results of species delimitation analyses coincide well with morphological differences observed among the island populations, reinforcing inferred species boundaries, and at least three potential cryptic species were statistically detected within Taiwan.Main conclusions Miocene-Pliocene geological events appear to have contributed disproportionately to diversification in the M. taiwanensis species group. The clear association between geographical area, genetic structure and statistical species delimitation strongly supports an interpretation of allopatric speciation. We advocate comparing our results with those derived from additional study organisms with similar life histories to further explore the Miocene-Pliocene diversification hypothesis.

“…Morphological differences in various island po-pulations are more or less obvious in whip scorpions (Haupt & Song 1996), Mesothelae (Haupt 1983(Haupt . 1990Ono 1996Ono , 1997, Hexathelidae (Shimojana & Haupt 1998) and Ctenizidae. In the last case, these differences have sometimes turned out to be slender and some characters show such great variation that they become useless for the distinction of species.…”

Japanese and Taiwanese species of the genus Latouchin are revised. Because of insular variability, trinary nomenclature has been introduced. Since body size and arrangements of setae and trichobothria are extremely variable, few characteristics can be used to distinguish species. Latouchin swinhoei swinhoei, L. japonica and L. formosensis formosensis are redescribcd. based on the type material, as far as available, and the female of L. swinhoei swinhoei. and the male of L. fiirrnoscnsis j?irmosen.si+ are also described. While the Yaeyama populations are newly described as L. formosensis hylo n. ssp., populations from Kumejima north to Honshu are considered as subspecies of L. swinhoei: L. s. kume n. ssp., L. s. ton& n. ssp.. L. s. keronrrr n. ssp., L. s. izena n. ssp., L. s. xena n. ssp., L. s. crypta n. ssp., L. swinhoei typica n. comb. L. parameleomene n. sp. is described from Okinawa on the basis of a particular setae pattern of the male pedipalpal tarsus. L. japonica is presently considered as incertae sedis, as the male remains unknown.Latouchia swinhoei typica n. comb. Figs 7i. 8 J a p a n e s e n a m e : Kishinouye totategumo.

“…They usually build funnel webs using crevices and cavities in slopes, occasionally build web in surface deciduous layers. So far, the family has 47 species of two genera reported worldwide ( World Spider Catalog 2022 ), of which 29 species are known from China ( Pocock 1901 , Saitô 1933 , Hu and Li 1986 , Shimojana and Haupt 1998 , Song et al 1999 , Zhu et al 2000 , Zhu and Song 2000 , Xu and Yin 2001 , Xu et al 2002 , Li and Zha 2013 , Shi et al 2018 , Yang et al 2018 , Yang et al 2019 , Wang et al 2019 , Tang et al 2020 , Chen et al 2020 , Lin et al 2021 , Tang et al 2022 ).…”

The family Macrothelidae Simon, 1892 belongs to the infraorder Mygalomorphae, currently contains two genera and 47 described species, from South Europe, South, and East Southeast Asia, Central, West, and North Africa. Two new species of the funnel-web spider genus Macrothele Ausserer, 1871 from Yunnan Province, China are described: Macrothele washanensis Wu & Yang, sp. n. (♂♀), and M. wuliangensis Wu & Yang, sp. n. (♂♀). Detailed descriptions, diagnostic illustrations and distribution map are provided. All specimens are deposited in the Institute of Entomoceutics Research, Dali University (DUIER).
