Abstract: Four species complexes have been recognized for >20 yr; one is monotypic, and the compositions of the others have changed because of new descriptions and synonymy. An early prediction concerning the proper placement of one species is confirmed, and with this proviso, the three modified complexes are shown to be monophyletic. Two undescribed species are placed, resolutions of problematic relationships are offered, a new species complex is defined, range extensions are recorded, and a scanning elec

Although the ant-fauna of Texas, New Mexico and Arizona comprises a greater number of species than that of the whole remaining portion of America north of Mexico, it has never been made the subject of systematic investigation. In the following study I have brought together the scattered and rather meager materials published by previous authors and have added several new forms, especially of Pheidole
, a cosmopolitan genus represented by a great number of species in tropical and subtropical America. A residence of four years (1899-1903) in central Texas, several excursions to the Trans Pecos deserts of that State, and a journey through New Mexico and Arizona during the spring of 1905, have enabled me not only to secure the large series of specimens now deposited in the American Museum of Natural History, but also to observe the living ants in their natural environment. This, as every myrmecologist knows, is often of the greatest importance in determining the status of species, subspecies and varieties.

The distribution of 291 known species of Texas ants was recorded from published literature and examination of identified museum specimens. For each species, all counties of known occurrence are given as well as a distribution map...
