A Taxonomic Review of the Genus Telsimia Casey (Coleoptera, Coccinellidae) from China, with Descriptions of Eight New Species.

Simple Summary: The Telsimia species are known as important predators of diaspidine scale insects that infest citrus, coconut, camphor, and bamboo plants, among others. A clear understanding of Telsimia species diversity and their geographical distribution forms the basis for the introduction and utilization of these natural enemies. At present, 48 species (subspecies) are known around the world, and studies on Chinese Telsimia species are relatively scarce. In this paper, 20 species of the genus Telsimia from China are reviewed, including eight new species and two new records. This taxonomic study can provide a theoretical basis for the development and utilization of Telsimia species for biological control of diaspidine scale insects. Twenty species of the genus Telsimia from China are reviewed herein. Among them, eight species are described as new to science: Telsimia chayuensis, T. forcipata, T. latus, T. lobatus, T. lunata, T. menglaensis, T. parascymnoides, and T. parvus spp. nov.; two species are reported from China for the first time: T. darjeelingensis Kapur, 1969 and T. elongate Hoàng, 1985. All species are provided with nomenclatural history, diagnoses, detailed descriptions (except for the 10 previously described species), colored illustrations, and distributions. The female genitalia of five described species are provided for the first time. A distribution map and a key to all the Chinese species are also provided. [ABSTRACT FROM AUTHOR]
