Tetramorium (Triglyphothrix) new species
Cameroun FK sp 20
  Type location Cameroun
TL ca 3.8 mm, HL 0.90 HW 0.75 CI 84 SL 0.67 SI 87 PW
0.58 EL 0.20 OI 25
This appears close to Tetramorium osiris with which
the following comparisons, but is significantly larger, TL ca 3.3 mm, cf
TL 2.8-2.9. The erect hairs also are shorter but are still longer
than the maximum eye diameter; the tibia hairs are about as long as the
maximum width of the tibia. Mandibles appearing to have fine spiculate
sculpturation. This has a
well defined median carina on
the clypeus, absent in magnificumand
lateral carinae.
The alitrunk profile less convex. Propodeal spines narrow and sharp but
straight not curved. The petiole
profile is lower. Head with slightly stronger sculpture, especially the
spiculation in the antennal scrobe. Form of erect hairs difficult to
ascertain as rather matted, all seemingly at least trifid, other than
longer simple hairs on the occiput; scapes without erect hair but
abundant sub-erect pubesence. This is medium yellow-brown, with the
gaster only a
little darker (osiris brown,
gaster very dark brown). Bolton
(1976: 332) compared osiris also
with Tetramorium
lanuginosum but this is more slender and elongated than
that (TL 2.2-3.0). It also has minute but distinct hair pits on the
gaster and seemingly at least trifid hairs.
