Pheidole nkomoana Forel - new status

return to key {link to the Hymenoptera Name Server} Type location Zare (Pheidole megacephala F. r nkomoana n. stirps, Forel, 1916: 415, all forms) from St Gabriel, collector H Kohl. .


Forel's (1916) description of nkomoana, which he felt might be a distinct species [and seems likely], is at {original description}. Forel noted Kohl had made several collections, always from in myrmecophile plants.

Minor, two specimens. Overall slender and elongated; very dark red-brown; funiculi, forecoxa, base of all femora and tarsi yellow. Elongated but ovoid head with frontal carinae distinctively raised and extending forwards in points (similar to those in Pheidole nimba). Clypeus smooth and paler. Head with faint lateral rugae rest shiny but surface uneven with indistinct sculpturation. Eyes moderate but convex and set forwards of the midline of the face. Scapes long and slender; funiculus with segment 9 unusually longer than 10 and almost as long as apical segment 11. Dorsum and lateral pronotum shiny and near unsculptured but uneven (as head); mesonotum, propodeum and pedicel with dense spiculation. Propodeal spines short and triangular with sharp forward angled tips. Petiole with a rectangular apex in frontal view. Gaster completely smooth and shiny. Legs long with very slender tarsi. Abundant long, fine, erect hairs on head, scapes, pedicel and gaster giving a bristly appearance.
