Abstract

The large orb-weaving spider genus Araneus consists of numerous species with highly variable morphologies and behaviors, and phylogenetic analyses have suggested that the genus is polyphyletic. Here, we investigated the specimens of Araneus viridiventris Yaginuma 1969, A. noegeatus (Thorell 1895), and an undescribed species. They were morphologically similar to each other but differed from the type species of Araneus. Following our molecular phylogenetic analysis using the sequencing data of five genes, we describe a new genus, Leviaraneus n. gen., which contains these species. They are small spiders with a broad, green abdomen. Moreover, we described the unknown species as a new species, Leviaraneus halabala n. sp. Additionally, Leviaraneus noegeatus n. comb. is newly recorded from Thailand, and its male is described for the first time.
