Eurhopalothrix

The genus Eurhopalothrix occurs throughout the Neotropics and Indo-Australian tropics, where it is an inhabitant of forest leaf litter and soil.

Identification
Eurhopalothrix are characterized as basicerotines with 7-segmented antennae and triangular mandibles (Brown and Kempf, 1960; Bolton, 2003). The tribe basicerotini is taxonomically problematic as there is no single accepted classification of its species into genera. Baroni Urbani and de Andrade (2007) synonymized the tribe Basicerotini with the Dacetini and proposed that all basicerotine genera be placed in the genus Basiceros. Longino (2013) revised the New World basicerotine species with 7-segmented antennae and triangular mandibles, as Eurhopalothrix, and recognized 28 species. Other Eurhopalothrix species are found in Australia and southeast Asia.

Nomenclature

 *  EURHOPALOTHRIX [Myrmicinae: Basicerotini]
 * Eurhopalothrix Brown & Kempf, 1961: 44. Type-species: Rhopalothrix bolaui, by original designation.
 * [Eurhopalothrix Brown & Kempf, 1960: 202; unavailable name, proposed without designation of type-species.]
 * Eurhopalothrix junior synonym of Basiceros: Baroni Urbani & De Andrade, 2007: 88.

Taxonomic Notes
All taxa of genera Eurhopalothrix, Octostruma, Protalaridris, Rhopalothrix and Talaridris were combined in Basiceros, sensu Baroni Urbani & De Andrade, 2007: 90-93. Synonymy of all basicerotine genera under Basiceros, by Baroni Urbani & De Andrade, 2007: 88, is incorrect procedure as Rhopalothrix has priority. Basicerotine genus-rank taxonomy documented in Bolton, 2003: 183-185, is retained.
