The Rediscovery of Camponotus (Myrmaphaenus) Yogi Wheeler (Hymenoptera: Formicidae)

the basis for the treatment of yogi in The Ants of North America (2). Unfortunately, one of the key features chosen (the length of the antennal scape) was incorrectly described by Wheeler; hence the key for yogi in the above publication is confusing rather than helpful. It appears that yogi has been saved from even greater confusion only because so little additional material has been taken. In 2958 F. Raney found a few specimens at the Oak Creek Ranger Station in San Diego County, California. In 1963 the junior author took three colonies of yogi at Etiwanda, in San Bernardino County, California. The se.fior author at first refused to believe that this material could be yogi because it so. obviously failed to, agree with SVheeler’s descriptio.n. Then, in 1964, the two types .of yogi were discovered in the collection of the American Museum of Natural History. These established the fact that the Oak Creek and Etiwanda specimens are yogi. Several of the shortcomings of Wheeler’s description can be, attributed to his attempt to relate yogi to the subgenus Co[obopsis. Whether he realized it or not, Wheeler described important features of the head of the major of yogi from a position where it most closely resembled that of a Colobopsis major. That is to say, the head was not viewed in full face. but tilted forward until the truncated anterior portion and the mandibles were barely visible. There is no possible doubt about this for the. "broadly excised posterior border" which SVheeler described for the head of the’ yogi major
