& Fisher, 2012: 24, illustrated, worker) Kakamega Distr., Isecheno,

WORKER. HL 0.89, HW 0.57, SL 0.26, EL 0.24, PW 0.44, AIIW 0.43, AIIL
0.44, AIIIW 0.49, AIIIL 0.60, WL 1.00, MFL 0.48, CI 64, SI 46, EL/HW
0.42, EP 0.68, AIIW/AIIL 0.98, AIIIW/AIIIL 0.82.
With head in full-face view the midpoints of the outer margins of the
eyes just touch the outlines of the sides of the head. Eyes located
relatively far in front of midlength of head, EP 0.68. ES 0.21 and
width of head across broadest part of eyes 0.55; minimum distance
between eyes 0.24. Frontal carinae extend back to level of anterior
margins of eyes and are weakly divergent posteriorly. Cephalic dorsum
with scattered broad, shallow punctures. Sparse weak longitudinal
ground sculpture also present in places between the eyes, but this
fades out and vanishes behind the level of the posterior margins of the
eyes. 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 numerous curved setae.
Mesosoma in dorsal view narrowest across the mesonotum (maximum width
0.40), broadest across the propodeum (maximum width 0.44). Pronotum
marginate anteriorly; promesonotal suture almost effaced. Propodeum
with a fine weak carina between dorsum and declivity. Entire dorsum of
mesosoma with broad, shallow punctures that are irregularly spaced.
Mesopleuron almost smooth, with just 1–2 punctures and a distinct
transverse sulcus. In profile, dorsal surfaces of mesosoma and all
abdominal tergites with numerous short, posteriorly curved setae that
are subdecumbent to decumbent and densest on AII and AIII. Standing
short setae are sparsely present on middle and hind tibiae. AII
(petiole) in dorsal view with a weak transverse carina both anteriorly
and posteriorly; sides almost parallel, only extremely feebly convex,
the width across the anterior margin is almost the same as across the
posterior margin. Dorsum of AII with scattered, shallow punctures;
tergite of AIII with similar but more densely crowded punctures. On the
tergite of AIV punctures are smaller than on AIII but are about of
equal density. AII and AIII longer than broad, AIII distinctly so; AIV
slightly broader than long (width 0.58, length 0.56). Head capsule and
body blackish brown to black; scapes and funiculi dull yellow; legs
yellowish brown to light brown, the femora slightly darker than the
Holotype worker, Kenya: Kakamega Distr., Isecheno, Kakamega Forest,
0.24°N, 34.86°E, 1600 m, 22.iv.2003, #03-109, equatorial rainforest: in
live stem of plant [the word “plant” is overwritten by a partially
legible entry “.....caena”, perhaps Dracaena],
(R.R. Snelling) (LACM).
This small species has relatively small eyes that are located farther
forward on the head capsule than any other known member of the schoutedeni group. See notes under schoutedeni.
