Ho/ocoryzoAlluaud, 1919, sea-side beetles of the Indian, Atlantic (sensu lato), and Pacific Oceans: a generic synopsis and description of a remarkable new species from Baja California Sur, Mexico (Coleoptera, Carabidae, Scaritini, Clivinina)

Information on the three previously described species of Halocoryza Alluaud is updated and a new species for the genus from Isla Carmen, Sea of Cortes, Baja California Sur, Mexico is described. Halocoryza whiteheadiana sp. n. was found at UV light on a beach of that island. This species does not fit the profile of the other three species, i.e., living on coralline beach sands, or in the Mangrove intertidal zone. Two alternative possibilities as to why this is so are suggested and a study plan for testing these possibilities is proposed. Resumen Information de las tres especies de Halocoryza Alluaud previamente descritas se actualiza y una especie nueva para el genero se describe de la Isla de Carmen, Mar de Cortes, Baja California Sur, Mexico. Halocoryza whiteheadiana sp. n. se encontro a luz UV en la playa de esa isla. Esta especie no corresponde con los perfiles de las otras tres especies (por ejemplo, viviendo en arenas coralinas de playa o en la zona intermareal en el manglar. Dos posibles alternativas para la razon de esto son sugeridas y un plan de estudio para probar estas posibilidades se propone. Copyright Terry L Erwin.
