ORTEGA-DE SANTIAGO, José Luis  and  VASQUEZ-BOLANOS, Miguel. A new species of Dolichoderus (Hymenoptera: Formicidae) from Puerto Vallarta, Jalisco, and new records for Mexico. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.4, pp.1004-1008. ISSN 2007-8706.  https://doi.org/10.7550/rmb.30508.

We describe Dolichoderus tridentanodus sp. nov. collected in Puerto Vallarta, Jalisco, Mexico based on workers, which is placed in the lugens complex. This species can be distinguished from D. lugens by the presence of 6 teeth in the internal margin of the mandible, 2 spines on the dorsal face of the propodeum, 2 lateral projections on the petiole and 1 central spine; body with abundant golden pubescence, densely and uniformly covered with coarse punctures; dark color, with yellow mandibles, clipeus, antenna and legs. This species is known for the states of Jalisco, Nayarit and San Luis Potosí. We provide a key for all the species of Dolichoderus in Mexico, and data of distribution with new records for some states.
