History and classification
When described Agroecomyrmex was known only from five separate fossils, the
Description
The new genus was described from a full alate female and four workers, all of the workers being preserved in a curled up position, obscuring details. Overall it is estimated the female would have been around 5.5 millimetres (0.22 in) long while the workers range between 4 and 5 millimetres (0.16 and 0.20 in). A. duisburgi individuals have heads which are nearly square, being just slightly longer than wide, and slightly wider behind than in front. Individuals have small, very convexly shaped eyes which are placed near the back edge of the head capsule and completely lack ocelli. The mandibles are short and rounded, and have 5 unequal teeth. The antennae are composed of thirteen segments, the terminal three forming a distinct club shape. The head and thorax have a strongly reticulated structuring to the exoskeleton and having an overall black coloration.[1] Agroecomyrmex can be separated from Eulithomyrmex based on the features of the head, with Agroecomyrmex displaying larger mandibles and a smaller antennal club.[4]
