“…Two studies (Ledford and Griswold 2010;Ledford et al 2011) assessed the phylogeny of North American leptonetids using nucleotide sequence data and better defined the genera. During the past 10 years, the most striking advances in leptonetid taxonomy have been in Asia where over 100 new species have been described from China and South Korea (Chen et al 2010;Lin and Li 2010;Li 2010, 2011;Seo 2015aSeo , 2015bSeo , 2016aSeo , 2016bGuo et al 2016;He et al 2019;Xu et al 2019). Although most of these studies do not include phylogenetic or biogeographic analyses (but see Wang et al 2017), they have greatly improved our understanding of the Asian fauna.…”

Leptonetidae are rarely encountered spiders, usually associated with caves and mesic habitats, and are disjunctly distributed across the Holarctic. Data from ultraconserved elements (UCEs) were used in concatenated and coalescent-based analyses to estimate the phylogenetic history of the family. Our taxon sample included close outgroups, and 90% of described leptonetid genera, with denser sampling in North America and Mediterranean Europe. Two data matrices were assembled and analysed; the first ‘relaxed’ matrix includes the maximum number of loci and the second ‘strict’ matrix is limited to the same set of core orthologs but with flanking introns mostly removed. A molecular dating analysis incorporating fossil and geological calibration points was used to estimate divergence times, and dispersal–extinction–cladogenesis analysis (DEC) was used to infer ancestral distributions. Analysis of both data matrices using maximum likelihood and coalescent-based methods supports the monophyly of Archoleptonetinae and Leptonetinae. However, relationships among Archoleptonetinae, Leptonetinae, and Austrochiloidea are poorly supported and remain unresolved. Archoleptonetinae is elevated to family rank Archoleptonetidae (new rank) and Leptonetidae (new status) is restricted to include only members of the subfamily Leptonetinae; a taxonomic review with morphological diagnoses is provided for both families. Four well supported lineages within Leptonetidae (new status) are recovered: (1) the Calileptoneta group, (2) the Leptoneta group, (3) the Paraleptoneta group, and (4) the Protoleptoneta group. Most genera within Leptonetidae are monophyletic, although Barusia, Cataleptoneta, and Leptoneta include misplaced species and require taxonomic revision. The origin of Archoleptonetidae (new rank), Leptonetidae, and the four main lineages within Leptonetidae date to the Cretaceous. DEC analysis infers the Leptoneta and Paraleptoneta groups to have ancestral distributions restricted to Mediterranean Europe, whereas the Calileptoneta and Protoleptoneta groups include genera with ancestral distributions spanning eastern and western North America, Mediterranean Europe, and east Asia. Based on a combination of biology, estimated divergence times, and inferred ancestral distributions we hypothesise that Leptonetidae was once widespread across the Holarctic and their present distributions are largely the result of vicariance. Given the wide disjunctions between taxa, we broadly interpret the family as a Holarctic relict fauna and hypothesise that they were once part of the Boreotropical forest ecosystem.

“…Twenty-seven and 46 new species were reported by Wang and Li (2011) and Wang et al (2017), respectively. With three exceptions (Leptonetela pungitia Wang & Li, 2011;Leptonetela trispinosa;Leptonetela unispinosa), nearly all Chinese Leptonetela species are endemic to either a single cave or a cave system (Wang et al 2017;He et al 2019;WSC 2020). Study of additional caves in China may result in the discovery of more undescribed caveassociated Leptonetela species, but this still needs to be confirmed by future collecting.…”

“…Terminology in the present paper follows Wang et al (2017) and He et al (2019). The abbreviations used in the text and figures are as follows: Chen et al, 1982 in having a long tibial apophysis (TA) of palp, but differs by the detailed characters of TA (claviform, gradually more transparent from the base to the tip, with a small spine on its tip in this species vs finger-shaped and bifurcate distally in L. huanglongensis) (compare Figs 1B, C, E, 2B, 3A, B with Chen et al 1982: fig.…”

Three species of the genus Leptoneta Simon, 1872 deposited at Hunan Normal University, Changsha, China, are examined and redescribed. Two species are transferred from Leptoneta Simon, 1872 to Leptonetela Kratochvíl, 1978, and the following new combinations are proposed: Leptonetela trispinosa (Yin, Wang & Wang, 1984), comb. nov. (♀♂), and Leptonetela unispinosa (Yin, Wang & Wang, 1984), comb. nov. (♂). The generic placement of Leptoneta monodactyla Yin, Wang & Wang, 1984 is maintained. Detailed descriptions, illustrations, and a distribution map for all three species are provided.
