With head in full-face view the outlines of the outer margins of the
eyes very nearly touch the outlines of the sides of the head. ES 0.25
and width of head across broadest part of eyes 0.49. Cephalic dorsum
with scattered broad, shallow punctures. Ground sculpture almost
effaced between the eyes, here and there with vestiges but without
longitudinal fine striolae. Leading edge of scape with a few setae,
inclined toward the scape apex. Sides of head below and behind eyes
with projecting short setae, inclined anteriorly. Cephalic dorsum with
a number of short setae and with a few pairs of longer setae present on
the frontal carinae and above the eye. Ventral surface of head with
short setae. Mesosoma in dorsal view narrowest across the mesonotum
(maximum width 0.38), broadest across the propodeum (maximum width
0.39). Anterior margin of pronotum weakly marginate. Propodeal carina
between dorsum and declivity extremely feebly developed, almost
effaced. Entire dorsum of mesosoma with widely spaced broad, shallow
punctures that are most widely spaced on the pronotum. Mesopleuron with
a few punctures and a distinct transverse sulcus. In profile, dorsal
surfaces of mesosoma and all abdominal tergites with numerous
posteriorly curved setae. Standing setae present on middle and hind
tibiae. AII (petiole) in dorsal view with a weak transverse carina both
anteriorly and posteriorly; sides almost straight so that the width
across the anterior margin is almost exactly the same as across the
posterior margin. Dorsum of AII with scattered, shallow punctures.
Tergite of AIII with more crowded punctures, so that some are adjacent;
diameters of punctures always greater than the distances between them.
AII and AIII longer than broad, AIV broader than long (width 0.54,
length 0.47; AIVW/AIVL 1.15). Head capsule and body blackish brown to
black; scapes and funiculi light Holotype worker, Gabon: Prov.

10°23.7’E, 14.iii.2000, 640 m. 2246(25), CASENT0004519, beating low
vegetation, rainforest (B.L. Fisher) (CASC).
This small species appears closely related to amana, but its eyes are
located farther forward on the head and there is no dense, longitudinal
striolate ground sculpture between the eyes. See notes under schoutedeni. Brown; femora and
