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.
Leptoneta, Leptonetela, new combination, taxonomy
Leptonetids are small in size, usually less than 3 mm, with the body color entirely pale or yellowish (sometimes color varying between pale and yellowish) (
All specimens examined in this study are deposited in the College of Life Sciences, Hunan Normal University (

The family Leptonetidae comprises 353 species belonging to 21 genera worldwide. Only three genera, Leptoneta, Leptonetela, and the monotypic genus, Rhyssoleptoneta Tong & Li, 2007, are distributed in China (WSC 2020).
Chinese Leptoneta species have diverse morphological characteristics of the male palp and
The genus Leptonetela is mainly distributed in China. Nighty-eight species (including two new combinations in the current study) are described from China and only 12 from regions outside China including nine from Greece, one from Vietnam, one from Turkey and one from the Caucasus.
The quick increase of the number of Chinese Leptonetela species is mainly due to two excellent studies:
