The aptly-named Camponotus termitarius ^HNS is most commonly collected from old termite mounds in low-lying pastures and pastizales. This ant should be treated as a full species. Camponotus termitarius ^HNS is locally sympatric with C. punctulatus ^HNS (syntype w examined, NHMW), shows consistent differences in nesting site ( C. punctulatus ^HNS is a generalist groundnesting ant), and is morphological distinct in a number of characters. First, C. termitarius ^HNS is more pilose, being intermediate in this regard between the relatively hirsute C. hispidus ^HNS and the relatively bare C. punctulatus ^HNS, lacking extensive standing hairs on the side of the head but bearing>8 between the eye and the mandibular insertions. Second, the propodeum of C. termitarius ^HNS is lower, more elongate, and with a shorter declivitous face than that of C. punctulatus ^HNS. Third, the microsculpture of the gastric tergites is more extensive, giving the gaster a duller appearance than in either C. hispidus ^HNS or C. termitarius ^HNS. Finally, the pubescence is more extensive in C. termitarius ^HNS than in either C. hispidus ^HNS or C. termitarius ^HNS, with the fine appressed setae on the first gastric tergite separated by distances much shorter than the length of the setae and overlapping in places.
