Abstract
BACKGROUND: The genus Rhodotritoma Arrow, 1925 (Coleoptera, Erotylidae, Erotylinae, Tritomini) includes 12 known species worldwide, including three species distributed in China. In the last four decades, no work was conducted on Rhodotritoma in China. In this paper, we review the taxonomy of this genus for Chinese fauna and redescribe a newly-recorded species in China. NEW INFORMATION: Rhodotritomamanipurica Arrow, 1925 is recorded from China for the first time. The morphological characters of the adult are redescribed in detail and illustrated. A key to species of the genus Rhodotritoma Arrow, 1925 in China is provided. Chinese specimens were collected from Tibet Autonomous Region and Yunnan Province, which were then deposited in the Museum of Hebei University. The holotype examined is kept in the Natural History Museum.
