A review of the ant genus Adelomyrmex Emery 1897 (Hymenoptera, Formicidae) in Central America Author Longino, John T. text Zootaxa 2012 3456 1 35 journal article 10.5281/zenodo.282199 3e327a0c-9af2-4d20-bd5e-80f6e5f2f250 1175-5326 282199 7F5C6597-DCE6-45CA-9DD8-ED64139177E7 Adelomyrmex cristiani Fernández, 2003 Adelomyrmex cristiani Fernández, 2003: 16 , figs. 36, 75. Holotype worker: Colombia , Cordillera Occidental, transecto Tatamá, 1650 m , 1983 (Th. van der Hammen et al ., TAT 205) [ICN] (not examined). Geographic range. Colombia , Ecuador . Comments. The holotype of A. cristiani came from a series of Berlese samples from the Tatamá elevational transect studied by van der Hammen et al . (van der Hammen & Ward 2005 ). I examined three additional workers provided by P. S. Ward. Two were from two additional sites on the Tatamá transect (TATA206 and TATA212, at 1540 m and 1950 m elevation, respectively), and one was from a wet forest site in Pichincha Province, Ecuador , at 1500 m (PSW11503.9). The specimens showed discordant character variation. The Ecuador and TAT 212 specimens have similar mandibular dentition: there are three main apical teeth, two or three small denticles, and a broad triangular tooth that is near the basal tooth. Thus, these specimens exhibit the character of the Central American species A. dentivagans , A. mackayi , A. nortenyo , and A. quetzal . The mandibles on TAT206 are difficult to observe, but one partially open mandible appears to have a more typical dentition, lacking the large triangular tooth on the basal margin. The Ecuador and TAT 206 specimens have the petiolar node smooth and shiny; the TAT 212 specimen has the node irregularly rugose.
