Nomenclature

 *  satrapus. Camponotus (Myrmepomis) sericeiventris var. satrapa Wheeler, W.M. 1931c: 92 (s.w.q.) PANAMA.

Worker
 maxima Length 14-15 mm.; head 4.8 mm. long, 4.4 mm. wide ; hind tibia 5 mm.

Very similar to the typical sericeiventris but somewhat smaller and with more brilliant, golden pubescence, longer and denser on the vertex, thorax and petiole; hairs blackish at base, with yellow tips. Sides of head blackish or dark brown, smoother and more shining, their punctures sparser. Border of petiole usually produced or subdentate in the middle.

major, media and minor Length 6-13 mm.

Very similar to the corresponding phases of the typical sericeiventris but the pubescence is more golden, as in the maxima, and the petiolar border is usually more or less distinctly subdentate in the middle.

Queen
Length about 16 mm.

Closely resembling the female of the typical sericeiventris but with entirely black head and thorax, the former more deeply excised behind and with much smoother and more shining sides, the petiolar border without a median notch and with less produced lateral corners. Wing membranes distinctly more deeply infuscated. Appressed pubescence more golden as in the worker satrapa, and the convergence of the pubescence on the second and third gastric segments even more pronounced than in the typical sericeiventris.
