Both species mentioned above are very active in open areas between 11:00 a.m. Dorymyrmex insanus and Dorymyrmex pyramicus are sympatric in the northern part of its distributional range. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.Ĭuezzo and Guerrero (2011) - The nest, briefly described by Wilson (1957), has a small entrance hall with more regularly formed craters than Dorymyrmex insanus. Neotropical Region: Belize, Colombia, El Salvador, Honduras, Jamaica, Mexico, Peru.Ĭheck data from AntWeb Countries Occupied Number of countries occupied by this species based on AntWiki Regional Taxon Lists. Nearctic Region: United States ( type locality). The identity of this complex could be solved with a more detailed and extensive research, especially comparing nest series from the west part of USA.ĭistribution based on Regional Taxon Lists bicolor belongs to a complex of species, as observed by Forel (1911). pyramicus has a promesonotal profile continuous, convex in lateral view). bicolor) and mesonotum interrupted in lateral view, with a well-defined dorsal and declivitous faces, often descending vertically or nearly so, into mesopropodeal suture, (as described below, D. pyramicus, because of its pattern of colors (orange head, mesosoma and petiole with dark gaster), but two main characters are useful to identify and to differentiate both species: head width (larger in workers and queens of D. Several species of Dorymyrmex ( Dorymyrmex pyramicus, Dorymyrmex thoracicus, etc.) have the same pattern of colors and could be confused with D. Maximum diameter the head behind of compound eyes. Queen Head slightly wider than long with the posterior margin of head strongly concave. Mesonotal profile continuous with pronotum, with a distinct dorsal and declivitous face before mesopropodeal suture. Dorsal face of pronotum with no erect setae. Posterior margin of the head slightly concave in frontal view. Feeds on living and dead insects and honeydew.Ĭuezzo and Guerrero (2011) - Worker CI equal or over 90. Nests in unshaded areas surmounted by a crater of fine sand. A desert species with common desert ant behaviors fast moving and forages at high temperatures. ![]()
