Abstract
Cahara Ghauri from China with three species is reviewed here. Two of them, Cahara incisura sp. n. and Cahara nodula sp. n. are described here. Key to the three Chinese species, habitus photographs and illustrations of genitalia are also provided. All examined materials including the types of three species mentioned are deposited in the Institute of Entomology, Nankai University, Tianjin, China (NKUM).
Highlights
Ghauri (1978) erected a new genus Cahara of Halyini to accommodate three species formerly belonged to genus Dalpada Amyot & Serville, 1843, and the other six new species
Xu and Zheng (1993) discussed the phylogenetic relationships of the nine genera of Dalpada-group including Cahara based on 18 morphological characters
Memon et al (2011) make a phylogenetic analysis using 61 morphological characters from 31 genera of south Asian Halyini, and the single most parsimonious tree shows that Ameridalpa Ghauri, 1982 is the sister group to Cahara, while the bootstrap support value is under 50%
Summary
Ghauri (1978) erected a new genus Cahara of Halyini to accommodate three species formerly belonged to genus Dalpada Amyot & Serville, 1843, and the other six new species. Later in 1986, Zheng and Liu (1986) reported one new species C. tibetana found in China. Xu and Zheng (1993) discussed the phylogenetic relationships of the nine genera of Dalpada-group including Cahara based on 18 morphological characters. Memon et al (2011) make a phylogenetic analysis using 61 morphological characters from 31 genera of south Asian Halyini, and the single most parsimonious tree shows that Ameridalpa Ghauri, 1982 is the sister group to Cahara, while the bootstrap support value is under 50%. Memon et al (2011) only define the south Asian Halyini, and indicate that the inclusions in the Halyini of many genera from other parts of the world is under discussion, but Cahara has always been placed in Halyini (Ghauri 1978, Zheng and Liu 1986, Xu and Zheng 1993, Memon 2002, Rider 2006, Memon et al 2011).
