A NEW SPECIES OF ODONTOMACHUS ANT (HYMENOPTERA: FORMICIDAE) FROM INLAND RIDGES OF FLORIDA, WITH A KEY TO ODONTOMACHUS OF THE UNITED STATES

Mark Deyrup, Stefan Cover

Abstract


The ponerine ant Odontomachus relictus n. sp. is described from specimens collected in scrub and sandhill habitats on several ancient sand ridges in Florida. It appears to be a relict species from dry periods in the Pleistocene. Workers are similar to the western species O. clarus Roger, but males of the two species are strongly divergent. Keys and natural history notes are provided for workers and males of the four Odontomachus species known from the U.S. Examination of males might help clarify the taxonomic status of Odontomachus of Central and South America.
