Challenging Wallacean and Linnean shortfalls: <i>Ectatosticta</i> spiders (Araneae, Hypochilidae) from China

Abstract

A: Phylogeny of 505 specimens inferred from IQTree and MrBayes using seven genetic markers. Support for each branch is shown at the nodes, with bootstrap percentages given first, followed by posterior probabilities. Different species delimitation methods are shown on the right.

B: Genitalia of females (a: Ectatosticta xuanzang ; b: Ectatosticta dapeng ; c: Ectatosticta davidi ; d: Ectatosticta baixiang sp. nov. ; e: Ectatosticta qingshi sp. nov. ; f: Ectatosticta helii sp. nov. ; g: Ectatosticta bajie ; h: Ectatosticta shaseng sp. nov. ; i: Ectatosticta rulai ; j: Ectatosticta yukuni ; k: Ectatosticta puxian sp. nov. ; l: Ectatosticta wukong ; m: Ectatosticta baima sp. nov. ; n: Ectatosticta deltshevi ; o: Ectatosticta wenshu sp. nov. ). C: Distribution of Ectatosticta spiders in China. Dark spots represent locations of samples and correspond to Supplemnetary Table S1. The asterisk represents the species Ectatosticta shennongjiaensis .

Phylogenomics of paleoendemic lampshade spiders (Araneae, Hypochilidae, Hypochilus), with the description of a new species from montane California

“…Specimens representing the genus Ectatosticta Simon, 1892 from China, the sister genus to Hypochilus (and the only other hypochilid genus described), were used to root all phylogenies (UCE data from Ramírez et al 2021). The monophyly of the family, and two constituent genera, is strongly supported by both morphology (Forster et al 1987;Alberti and Coyle 1991;Catley 1994;Li et al 2021) and phylogenomics (Fernández et al 2018;Ramírez et al 2021). Phylogenomic data were gathered for forty-three Hypochilus specimens, representing all ten described species (see Suppl.…”

Taxonomic notes on the genus Phrynarachne from China (Araneae, Thomisidae)

“…Seven Phrynarachne species were known from China before the current study; only two species, i.e., P. ceylonica (O. Pickard-Cambridge, 1884) and P. katoi Chikuni, 1955, are described by both sexes. All endemic Chinese Phrynarachne species are only described by few single-sex specimens, and the species in the surrounding areas of China, except Japan, are not well revised and most of them have only initial descriptions ( Li et al 2021 ; WSC 2021 ; Yao et al 2021 ).…”

On eleven species of jumping spiders from Xishuangbanna, China (Araneae, Salticidae)

“…To date, the list of salticids from Xishuangbanna, including the eight new species described here, comprises at least 145 species, which is more than the number of species in several adjacent countries and regions (Logunov 2021;Wang and Li 2021;WSC 2022). However, there is no doubt that new records and species will be discovered in this biodiversity hotspot and the list of species will be increased further because most area of this region remains insufficiently surveyed (Wang et al 2020;Li et al 2021;Yao et al 2021).…”
