Abstract

Three new species of the spider genus Cicurina Menge, 1871, C. jinyun sp. nov. (♂♀), C. yinhe sp. nov. (♂♀) and C. zhangfui sp. nov. (♂), are described from Chongqing, China. Morphological descriptions, photographs, and illustrations of copulatory organs are provided. The number of documented Cicurina species in Chongqing increases from 10 to 13.

Introduction

The spider genus Cicurina Menge, 1871 has a complex taxonomic history, having been moved from Agelenidae to Dictynidae (Lehtinen, 1967), then to Hahniidae (Wheeler et al. 2017), before finally being placed in its own designated family, Cicurinidae (Gorneau et al. 2023). It comprises 86% (154 out of 179) of the species in the entire family, predominantly distributed across the Holarctic region, of which 114 species are distributed in North America (WSC 2025).

Cicurina spiders, characterized by their small size and secretive behavior, are typically found in leaf litter, under stones, and in caves, where they construct intricate small funnel webs that function as both shelters and hunting grounds (Gertsch 1992; Wang et al. 2019; Liao et al. 2022). Recent studies suggest that its diversity has been significantly underestimated, particularly in China where 31 species (10 in Chongqing Mun., 8 in Guizhou Prov., 5 in Hunan Prov., 3 in Guangdong Prov., 2 in Anhui Prov., 2 in Hubei Prov., 1 in Zhejiang Prov.) have been recorded (Chen 1986; Wang and Xu 1989; Song and Kim 1991; Wang 1994; Peng et al. 1996; Yin et al. 2012; Li and Wang 2017; Wang et al. 2019; Liao et al. 2022; Wang et al. 2024; Wang and Zhang 2025; WSC 2025). Based on our field experience, we speculate that numerous unknown Cicurina species likely exist in southern China, particularly in southwestern mountain areas.

In this paper, we describe and illustrate three new Cicurina species from Chongqing Municipality, China, with living specimen photos of two species. This work represents the third contribution to the study of Cicurina spiders in Chongqing, following Wang et al. (2024) and Wang and Zhang (2025).

Material and methods

All specimens were preserved in 75% ethanol and examined, illustrated, photographed and measured using a Leica M205A stereomicroscope equipped with a drawing tube, a Leica DFC450 camera and LAS software (ver. 4.6). Male palps and epigynes were examined and illustrated after they were dissected. Epigynes were cleared by immersing them in pancreatin (Álvarez-Padilla and Hormiga 2007). Eye sizes were measured as the maximum dorsal diameter. Leg measurements are shown as: total length (femur, patella and tibia, metatarsus, tarsus). All measurements are in millimetres. Specimens examined here are deposited in the spider collection at the School of Life Sciences, Southwest University, Chongqing, China (SWUC).
