Costa Rica: Meseta Central.
At LACM there are two old collections by A. Alfaro in 1936. One is from "La Fuente" and one from Atenas, both Central Valley sites. Roy Snelling identified these as elevatus. I briefly examined them in 1995 and concluded that they were a "shiny abscisus."
Roy Snelling compared material of dolabratus Menozzi with elevatus and concluded that the former was a junior synonym of the latter. During a type trip to Europe in 1990 I found a long worker series of dolabratus in the entomological museum in Eberswalde, Germany. The label data were "San Josˇ (C.R.) Heinr. Schmidt." One major had a red typus label. My notes on the types were:
These are unlike any other Camponotus I have examined. Major worker: head is almost exactly like my #1577 [cuneidorsus], a bit more bristly on cheeks, and yellow more extensive; same in side view, including curvature of the clypeus to form slight truncation of anterior portion of clypeus; mesosoma entirely different, dorsally flattened (like brevis rather than linnaei), not carinate, and with very deep, broad propodeal suture; dorsal face of propodeum prominently projecting; black and shiny, legs orange; a bit like a larger, more exagerated striatus, but without the striate sculpture and without the carinate propodeum; mesosomal dorsum long pilose; petiole broadly lenticular, thin, but not dorsally carinate.
