Description: Chrysina karenrobackerae Robacker and Hawks and C. queretaroensis Robacker and Hawks (Coleoptera: Scarabaeidae: Rutelinae) are described as new species from the northeastern Mexican states of Nuevo León and Querétaro, respectively, based on morphometric comparisons of adults and genitalia with those of C. adelaida (Hope, 1841) and C. occidentalis Robacker and Hawks, 2022. Both new species were previously regarded as C. adelaida and remain in the adelaida group (sensu Hawks 2001). Te primary diagnostic characters that defne these species are genitalic, including male-capsule enantiomorphy, a character not previously used in Chrysina Kirby identifcation.

Ambas especies nuevas se consideraban previamente como C. adelaida y permanecen en el grupo adelaida (sensu Hawks 2001). Los caracteres diagnósticos primarios que defnen a estas especies son genitálicos, incluida la enantiomorfía de la cápsula masculina, un carácter no utilizado previamente en la identifcación de Chrysina Kirby.
