Abstract

Two new species of the genus Smaragdina Chevrolat from China are reported: S.hejingensis Duan, Wang & Zhou sp. nov. from Xinjiang, and S.magnipunctata Duan, Wang and Zhou sp. nov. from Yunnan. Six species, S.divisa (Jacoby), S.insulana Medvedev, S.kimotoi Lopatin, S.laboissierei (Pic), S.laosensis Kimoto & Gressitt, and S.oculata Medvedev are new country records for China. Color illustrations and line drawings of general habitus and morphological details are given. All types of two new species are deposited in the collection of Institute of Zoology, Chinese Academy of Sciences (IZ-CAS).

Highlights

The genus Smaragdina Chevrolat, 1836 has 350 recognized species (Warchałowski 2012; Wang and Zhou 2013), making it the most species-rich genus of the tribe Clytrini
The genus is distributed in the Palearctic, Oriental, and Afrotropical regions, with 64 species found in China
The Chinese species of Smaragdina have been studied by many specialists (e.g., Gressitt and Kimoto 1961; Tan et al 1980; Kimoto and Gressitt 1981; Lopatin and Konstantinov 2009; Regalin and Medvedev 2010), but most of these studies were comprehensive and included all or most of the family Chrysomelidae, and Smaragdina was treated as only a part in those broader studies

Summary

Introduction

The genus Smaragdina Chevrolat, 1836 has 350 recognized species (Warchałowski 2012; Wang and Zhou 2013), making it the most species-rich genus of the tribe Clytrini. Medvedev 2010; Warchałowski 2010, 2012; Wang and Zhou 2013) This genus is similar to Aetheomorpha Lacordaire, 1848 but can be distinguished by the slight epipleural lobe of elytra and the pygidium covered by the elytra (Warchałowski 2012). Some recent studies on Smaragdina have included excellent keys to the species from the Oriental and Palearctic regions and, are very important in identifying the Chinese species (Medvedev 2010; Warchałowski 2010). The most recent study on Smaragdina was by Wang and Zhou (2013), which is part of the series of publications concentrated on the Chinese leaf beetle fauna (Wang and Zhou 2011, 2012, 2013, 2020; Su and Zhou 2017; Duan and Zhou 2021; Duan et al 2021a, 2021b)
