Lachnomyrmex scrobiculatus Wheeler ^HNS.

Chiapas, one specimen, soil. In Wheeler's original description and figure, the number of antennal segments is given as twelve. Dr. M. R. Smith and Dr. K. Yasumatsu have both called this count to question (in litt.), and the types in the Museum of Comparative Zoology show that there are really only eleven segments. The specimen taken by Dr. Goodnight compares well with the types in every respect. Wheeler related this genus to Agraecomyrmex ^HNS from the Baltic Amber, but Agroecomyrmex ^HNS seems entirely different, and possibly intermediate between the Ectatommini and the Myrmicini ^HNS. Lachnomyrmex ^HNS seems more closely related to Rogeria ^HNS by virtue of the thoracic structure and the eyes, sculpture, and pilosity.
