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.

Highlights

Calleida Latreille, 1824 is a genus of Lebiini Calleidina (Coleoptera, Carabidae) with rich species diversity mainly distributed in tropical and subtropical regions of the Americas, Sub-Saharan Africa and Southeast Asia (Casale 1998)
When studying morphologies of each species, we found that the female reproductive tract has very important value of inferring species relationships of the Oriental Calleida
In the cladogram generated with the successive weighting (SW) method, the monophyly for each species group was corroborated with the exception of the C. discoidalis group which was posited as a polyphyletic group

Summary

Introduction

Calleida Latreille, 1824 is a genus of Lebiini Calleidina (Coleoptera, Carabidae) with rich species diversity mainly distributed in tropical and subtropical regions of the Americas, Sub-Saharan Africa and Southeast Asia (Casale 1998). As the second part of our contributions to the Oriental species of Calleida, the present paper is mainly dedicated to revision of the C. discoidalis species group This group is defined as follows: abdominal sternite VII with four or more setae in males (two or more on each side), six or more setae in females (three or more on each side); abdominal sternite VII notched in males (Figs 2, 5); endophallus with two short copulatory pieces. Two of them were described previously, and four are here described as new species
