A new species of the ant genus Bothriomyrmex Emery, 1869 (Hymenoptera: Formicidae) from the Caribbean region Author Matthew Prebus Author David Lubertazzi text European Journal of Taxonomy 2016 211 1 12 journal article 10.5852/ejt.2016.211 5868b656-a0c2-4f5f-a132-7daf9e0b2eb4 269330 9A706453-A104-45FB-8B9C-92C8D18723A4 Arnoldius ( Dubovikoff, 2005 ) AU01 AUSTRALIA : 1 worker , Queensland , Smithfield Conservation Park 16.8167° S , 145.6833° E , 70 m , 9 Mar. 2006 , rainforest, sifted litter (leaf mold, rotten wood), A.

In 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 .
