Validation of Chrysina valentini Zubov and Ivshin, 2019 (Coleoptera: Scarabaeidae: Rutelinae) by morphometric and cuticular reflectance analyses
- Micromorphometric analyses of genital capsules and comparison of adult cuticular reflectance of two species of Chrysina Kirby (Coleoptera: Scarabaeidae: Rutelinae) support the status of C. valentini Zubov and Ivshin, 2019 as a valid species. Compared with its closest relative C. optima (Bates, 1888), capsules of C. valentini are proportionately wider at the base of the parameres than those of C. optima, and taper toward the apex more abruptly. Reflectance of C. valentini under natural light appears slightly greenish while C. optima is uniformly reddish. The number of teeth on the protibia and the shape of the mesosternal process, characters cited by Zubov et al. (2019) to distinguish the two species, did not prove reliable.
- Los análisis micromorfométricos de cápsulas genitales y la comparación de la reflectancia cuticular adulta de dos especies de Chrysina Kirby (Coleoptera: Scarabaeidae: Rutelinae) apoyan a C. valentini Zubov e Ivshin, 2019 como especies válidas. En comparación con su pariente más cercano C. optima (Bates, 1888), las cápsulas de C. valentini son proporcionalmente más anchas en la base de los parameres que las de C. optima, y se estrechan hacia el ápice más abruptamente. La reflectancia de C. valentini bajo luz natural aparece ligeramente verdosa mientras que C. optima es uniformemente rojiza. Número de dientes en la tibia de la pata delantera y forma de la apófisis mesoesternal, caracteres citados por Zubov et al. (2019) para distinguir las dos especies, no resultó confiable.
