  Notes on the identity of the orb-weaver spider Araneus nox Simon, 1877 (Araneae: Araneidae) from India, including its transfer to Eriovixia Archer, 1951 and one new synonymy The orb-weaver genus Araneus Clerck, 1757 has historically served as a heterogeneous assemblage for numerous araneid spiders lacking clear generic placement, and several Asian species formerly assigned to Araneus have subsequently been transferred to more narrowly defined genera. One species that still needs further investigation on its true identity is Araneus nox (Simon, 1877), originally described as Epeira nox Simon, 1877 from Basilan Island, Philippines, and later transferred to Araneus by Simon (1905). In the same year as the description of Epeira nox, Thorell (1877) described Epeira pilula from the Moluccas (Indonesia), which was subsequently synonymised under Epeira nox by Simon (1880). Despite its broad Oriental distribution, the taxonomic identity and generic placement of A. nox have remained insuff...

Two new species of the genus Trilacuna Tong & Li, 2007 (Araneae, Oonopidae) from the Nangunhe Nature Reserve, Yunnan Province, China

Abstract

Background

The spider genus Trilacuna Tong & Li, 2007, currently comprises 32 species known from China, of which 15 species are from Yunnan and one species, i.e. T. wumanshan Tong, Yang & Zhang, 2023 is recorded from the Nangunhe Nature Reserve, Yunnan.

New information

Two new Trilacuna species, Trilacuna jimengi Dai & Tong, sp. nov. (♂♀) and Trilacuna nangunhe Dai & Tong, sp. nov. (♂♀), are described, based on specimens collected from the Nangunhe Nature Reserve, Yunnan Province. Morphological descriptions and photomicroscopy images of the new species are given.
