Description of a new species of the carabid genus Harpalus Latr. from the Southwestern United States, with remarks on the composition of the subgenus Glanodes Casey (Coleoptera, Carabidae)

Abstract

Harpalus apache sp. n. is described from the eastern part of New Mexico, USA (type locality: Hwy I 40, near Santa Rosa, Guadalupe Co). The new species is very similar in appearance to H. cordatus (Le-Conte, 1853) but readily distinguished from it by the male genitalia structure. These two species constitute a natural taxon which is included as the “cordatus” group (= Opadius Casey, 1914) in the subgenus Glanodes Casey, 1914. Distinctive characters, distribution and composition of the subgenus Glanodes and two its species groups (“obliquus” and “cordatus”) are provided. Two names, H. cordatus (LeConte, 1853) (= H. tadorcus Ball, 1972) and H. puncticeps (Casey, 1914) (= H. cunctipeps Ball, 1973), rejected because of the secondary homonymy, are reinstated as valid since they are not homonyms of Ophonus cordatus (Duftschmid, 1812) and Ophonus puncticeps Stephens, 1828, respectively.
