New species, notes on the biology of Scaptolenus LeConte (Coleoptera: Elateridae), and a key to the ``vagans-group{''}

Abstract

Two new species of the genus Scaptolenus LeConte (Coleoptera: Elateridae: Elaterinae: Cebrionini) from Mexico are described and illustrated: Scaptolenus pacofierroi sp. nov., found in the municipality of Aldama, in the state of Tamaulipas and Scaptolenus zuritai sp. nov., collected from the Chamela-UNAM Biological Station, in the state of Jalisco. Their segregation is based on the morphological configuration of their antennae, aedeagus, protibiae and metacoxal lamina. These new species fit well within the vagans-group and a key is presented to distinguish these new species within the vagans group. Additionally, distribution data of these new species are provided and biological data of the genus Scaptolenus are presented and analyzed.
