The Bolboceratidae, Geotrupidae (Coleoptera, Scarabaeoidea), and Scarabaeinae (Coleoptera, Scarabaeoidea, Scarabaeidae) fauna of Honduras: Taxonomy and distribution

A biodiversity and distribution analysis of the beetle families Bolboceratidae and Geotrupidae, and the subfamily Scarabaeinae (Scarabaeidae) of Honduras is presented for the first time. The checklist contains 98 species: two Bolboceratidae, one Geotrupidae, and 95 Scarabaeinae. The fauna of Honduras includes two genera of Bolboceratidae, one genus of Geotrupidae, and 22 of Scarabaeinae. <i>Onthophagus</i> is the most speciose genus, with 21 species, followed by <i>Canthon</i> (10 species) and <i>Copris</i> (9 species). Valid names and synonyms are provided. First country records, notes on presently recognized species, distribution maps, and biodiversity comparisons are included, and nomenclatural problems associated with species in question are discussed. <i>Phanaeus lempira</i> Kohlmann, Solís and Rivera, <b>sp. nov.</b> (Coleoptera: Scarabaeidae) is described as a new species. <i>Canthon sallei</i> Harold, 1863 and <i>Canthon spinosus</i> Harold, 1863 are reinstated as valid species. <i>Canthon cyanellus</i> LeConte, 1859 does not contain any subspecies. Two new synonymies are established: <i>Canthon cyanellus violetae</i> Halffter, 1961, <b>syn. nov.</b> of <i>Canthon sallei</i> Harold, 1863; <i>Canthon speciosus</i> Harold, 1868, <b>syn. nov.</b> of <i>Canthon spinosus</i> Harold, 1863.
