The first record of the thomisid genus Ibana Benjamin, 2014 (Araneae, Thomisidae) from China, with the description of a new species

Abstract

The genus Ibana Benjamin, 2014 was established, based on the type species Ibana senagang Benjamin, 2014 from Borneo, Malaysia. No species of this genus has been recorded from China. A new species of Ibana is described and illustrated, representing the first record of the genus for China. Ibana gan sp. n. differs from its congener by the yellowishbrown longitudinal band on the abdomen and the round, contiguous spermathecae. The distribution of the new species in Jiangxi Province is mapped.

A new species of Mallinella Strand, 1906 (Araneae, Zodariidae) from South China

“…In the last three years, collections in Jiangxi Province in China led to the discovery of some new spider taxa, such as Agelenidae ( Liu et al 2021 , Liu et al 2020a ), Corinnidae ( Liu et al 2022b ), Phrurolithidae ( Liu et al 2020b , Liu et al 2020c , Liu et al 2021 , Liu et al 2022f ), Salticidae ( Liu et al 2022a ), Thomisidae ( Liu et al 2022c , Liu et al 2022e , Li et al 2022 ), Gnaphosidae ( Liu et al 2022d ), Trachelidae ( Zhang et al 2022 ) and now Zodariidae (this study). These discoveries support the fact that this Province still has distributions of many unknown species because of the lack of systematic research and attention.…”

Two new thomisid species (Arachnida, Araneae, Thomisidae) from China and Vietnam, with the first descriptions of the males of Borboropactus longidens Tang & Li, 2010 and Stephanopis xiangzhouica Liu, 2022

“…More than 50% of the Chinese species are from southern provinces of this country, such as Yunnan, Hainan and Hunan. Only a few percent of the total Chinese number of species have been reported in the past ten years ( Li and Lin 2016 ; Liu et al 2017 , 2022b , 2022c ; Yu and Zhang 2017 ; Yu et al 2017 ; Tian et al 2018 ; Lin et al 2019 , 2022 ; Huang and Lin 2020 ; Wang et al 2020 ; Liu et al 2021 ; Zhang et al 2022 ). China not only has the most species- and genus-rich thomisid fauna, but for approximately 65%, only one of the sexes has been described, which represents a challenge for future taxonomic revisions ( Li 2020 ).…”
