Myrmopytia

Supermodel Carpenter Ants

Diagnosis. Emery (1925). - "Worker. Caste dimorphism weak. Head elongate, narrowed as or curve or in ogive (missile-shape) posterior to eyes, or in minors, head extended as small collar. Clypeus subcarinate, produced anteriorly as short, truncate lobe. Mandibles slightly curved, with 6 teeth. Mesosoma very long and narrow; dorsum rounded; meso-metanotum very long, narrow, descending in a straight line to propodeum; propodeum forming high rounded bump. No vestige of sutures between mesonotum, metanotum, and propodeum; metanotal spiracles situated dorsally and prominent in profile view. Petiolar scale thick. Limbs very long.

Rasoamanana et al. 2017 - Minor workers of this subgenus can be recognized by the combination of the following characters: maxillary palps particularly long with respect to head length, extending past a point on line with posterior margin of eye; mesosoma slender, mesonotum elongated and constricted at midlength, propodeum a protruding rounded hump; mesothoracic spiracles prominent, pointing upward; propodeum protuberant. The major worker can be recognized by the distinct form of the mesosoma. The propodeum is dome-like or subrectangular in lateral view and the metanotum is elongate and impressed, and the upper mesopleuron is laterally pinched

Queen and male. - Unknown.

Geographical distribution of the species. - The only known species lives in Madagascar.

Note: The shape of the head and mesosoma of C. imitator, Forel, is characteristic; it calls to mind those of C. (Myrmosaulus) camelinus and singularis, but much exaggerated, and rather reminiscent of Prenolepis melanogaster, Emery. Perhaps this species should be excluded from the genus Camponotus. Forel points out the striking mimicry of C. imitator with Aphaenogaster (Deromyrma) swammerdami, Forel (hence the specific epithet). For the reports of C. imitator with shellac[!], see Forel, in Grandidier, ''Hist. Nat. Madagascar'', Vol. 20 (2), p. 210-218 (1891)."
