The Ants of
Africa Genus Camponotus subgenus Myrmopiromis |
Genus Camponotus |
Genus definition - Wheeler (1921a: 17) gave this as a replacement name for the Old World Myrmepomis, because Emery (1920b: 237) had set up Myrmolophus as a the new subgenus for the New World species but that was an error and Wheeler subjugated the latter as a junior synonym of Myrmepomis, necessitating the creation of a new subgenus name.
Head as in Orthonotomyrmex,
major very broad posteriorly,
minor trapezoidal, broadened posteriorly; genae without deep pits or
fossettes, on major and queen; most with coarse, fairly abundant,
obtuse hairs of a pale colour, sometimes forming a fur-coating on
gaster.
NOTE - Emery (1925b: 129) had - medium-sized, alitrunk dorsum with an impression anterior to propodeum - chrysurus-group (chrysurus & scalaris) but chrysurus moved by Santschi (1926a) to Myrmopelta and Camponotus scalaris Forel has been transferred by me to subgenus Myrmenosites as clearly quite distinct from any member of C (Myrmopiromis). I have also transferred Camponotus tameri (Weber) to subgenus Myrmacrhaphe as it is very similar to Camponotus (Myrmacrhaphe) rotundinodis.
Robertson & Zachariades (2007) revised the Camponotus fulvopilosus species-group.
