Revision of the Oriental species of Calleida Latreille (sensu lato). Part 2: the C. discoidalis species group (Coleoptera, Carabidae, Lebiini)

Abstract

The C. discoidalis species group of the genus Calleida Latreille from Asia (in the sense of Casale and Shi 2018) is revised with six species recognized. Four new species are described: C. piligera Shi & Casale, sp. n. (type locality: Taiwan: Siling, 24.65°N, 121.42°E); C. cochinchinae Casale & Shi, sp. n. (type locality: Vietnam: “Cochinchina”); C. yunnanensis Shi & Casale, sp. n. (type locality: Yunnan: Caiyanghe, 22.60°N, 101.12°E); and C. luzonensis Casale & Shi, sp. n. (type locality: Philippines: Nagtipunan, 16.22°N, 121.60°E). C. fukiensis Jedlička, 1963 is confirmed as an available and valid species name, and C. suensoni Kirschenhofer, 1986 is newly synonymized with it. A phylogenetic analysis of Oriental Calleida species, based on adult morphological characters, is performed. The results show that the monophyly of most species groups in Oriental Calleida is accepted, but the C. discoidalis group appears polyphyletic and comprises three lineages. However, because many species relationships in the cladogram lack significant supporting, presently the C. discoidalis group was remained to use for morphological convenience. Five types of female reproductive tracts were recognized, corresponding to five branches in the cladogram.
