In Table 2 View Table 2 we compare B. enigmaticus sp. nov., B. paradoxus , Chronoxenus wroughtoni and an undescribed species of Arnoldius to data collected from a morphometric study of Palearctic Bothriomyrmex conducted by Seifert (2012). In this context, some very general observations can be made about the morphological affinities of B. enigmaticus sp. nov.: the eyes of B. enigmaticus sp. nov., relative to cephalic size are the largest in this dataset, similar to the large-eyed B. paradoxus , C. wroughtoni , and B. corsicus . The antennal scapes are short as well, a feature shared by B. paradoxus , C. wroughtoni and A. AU01. Finally, the propodeum is compact and delineated by a deep metanotal groove, much like B. paradoxus , C. wroughtoni , A. AU01, and to a lesser degree B. corsicsus .
