Abstract

Background: Hogna Simon, 1885 is the second-largest genus in the family Lycosidae after Pardosa C. L. Koch, 1847 (517 species), including 232 species so far. This genus has a cosmopolitan distribution spanning multiple continents. However, only four species (Hogna rubetra (Schenkel, 1963), Hogna trunca Yin, Bao & Zhang, 1996, Hogna jiafui Peng, Yin, Zhang & Kim, 1997 and Hogna arborea Lo, Wei & Cheng, 2023) have been recorded in China.

New information: A new combination, Hogna bifasciata (Buchar, 1997), comb. nov. (from Yunnan and Sichuan Provinces in south-western China), is proposed with both morphological and molecular evidence. Detailed morphological descriptions, photographs, scanning electron micrographs and a distribution map are provided. This species is distinguished from congeners by the unique structure of the female epigyne and its somatic pattern. Molecular phylogenetic analyses suggest H. bifasciata (Buchar, 1997) and all analysed Hogna species cluster together within the subfamily Lycosinae and the species is sister to the group, including Hogna frondicola Emerton, 1885, Hogna carolinensis Walckenaer, 1805 and Hogna crispipes L. Koch, 1877.

Keywords: Lycosinae; DNA barcoding; morphology; new combination; phylogeny; taxonomy.

Phylogenetic tree reconstructed using the Maximum Likelihood method. A The Maximum Likelihood tree was reconstructed using the concatenated COI, 12S rRNA and 16S rRNA sequences of 329 species of Lycosidae; B The Maximum Likelihood tree was reconstructed using the concatenated COI, 12S rRNA and 16S rRNA sequences of 106 species of Lycosinae and Pardosinae. The numbers at the nodes represent bootstrap support values from the Maximum Likelihood analyses. The species Hogna bifasciata (Buchar, 1997) is shown with red colour in the phylogenetic trees.
