Tiger beetles are a popular group of insects amongst amateur naturalists, and are well-represented in museum and private collections. New species descriptions plateaued in the 19th century, but there is a recent resurgence of discoveries as integrative taxonomy methods, guided by molecular systematics, uncover “cryptic” tiger beetle diversity. In this paper, we describe a new species using multiple data types. This new species, Eunota mecocheila Duran and Roman n. sp., is in the tribe Cicindelini, and is described from specimens collected in saline muddy ditches in northern Mexico. This species is closely related to E. circumpicta (LaFerté-Sénectère, 1841), but is separated based on morphological differences, geographic range, and genetic differentiation. Little is known about the biology or distribution of this species and it has only been collected from two sites in the state of Coahuila. Given the location of this new species, and its genetic divergence from its closest relative, E. circumpicta, we discuss the historical biogeography that may have led to isolation and speciation. The male and female dorsal, lateral and frontal habitus and the male aedeagus are shown.
