Identification

Fernández and Guerrero (2008) - This extinct species is characterized by long scape, metanotum longitudinally striate, petiole very long and slender and the presence of one pair of long setae on vertex.

Nomenclature

The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • hispaniolae. †Iridomyrmex hispaniolae Wilson, 1985c: 32, fig. 10 (w.) DOMINICAN AMBER (Miocene). Combination in Linepithema: Shattuck, 1992a: 16; in Techomyrmex: Brandão, Baroni Urbani, Wagensberg & Yamamoto, 1999: 414. Incertae sedis in Technomyrmex: Bolton, 2007a: 123.

Type Material

  • Holotype, worker, Las Bocas del Licey, in amber, Dominican Amber (Miocene), Museum of Comparative Zoology; see Bolton (2007).
  • Paratype workers. (32 amber pieces) Dominican Republic: Carlos Diaz, El Valle, La Toca, Llaroa, Los Cacaos, Palo Quemado and Bayaguana (Museum of Comparative Zoology).

Fernández and Guerrero (2008) - There are two dolichoderine species described from Dominican amber that are ascribed to Technomyrmex (Brandão et al. 1999). However, Bolton (2007:122) points out that both species “lack some critical diagnostic characters of the genus, the absence of which would argue for their exclusion”. Bolton also questioned the classification of Technomyrmex hispaniolae in Iridomyrmex or Linepithema, leaving both taxa as incertae sedis in Technomyrmex.
