A New Species in Notobitiella Hsiao in China Confirmed by Morphological and Molecular Data (Hemiptera: Heteroptera: Coreidae)

Abstract

To date, only one species of genus Notobitiella, N. elegans Hsiao, was found in Yunnan, China. Recently, we confirmed a new species, Notobitiella bispinasp. nov., by morphological and molecular data based on new specimens collected from Yunnan, China. The new species is morphologically similar to N. elegans except for the male genitalia and the sternum of the seventh abdominal segment of the female. The extraordinary difference of the genitalia between these two species inspired us to erect a new genus for this new species. However, considering their sister group relationship to other genera in tribe Cloresmini and the 12.56~12.64% genetic distance (meeting the interspecific genetic distance within genus of tribe Cloresmini) by a complete COI gene, this species was more reasonable as a new species of the genus Notobitiella, and the diagnosis of the genus was revised. The photos of the body and critical morphological characteristics for both male and female were provided for accurate identification.

Keywords: Cloresmini; Notobitiella; bamboo; monotypic genus; species delimitation by COI.
