Crematogaster (Decacrema) costeboriensis
Santschi - new status
  Type location Ivory
Coast (Crematogaster (Decacrema)
solenopsoides Em. stirps
costeboriensis n. st., Santschi, 1919h: 86, worker) collected at
Region of
San Pedro, by C. Phore (on label as C. Thoiré, 1901)  .

Santschi's (1919h)
description is at  .
I have separated this from Crematogaster (Decacrema) solenopsides
as it is quite clearly different from the specimen of solenopsides that I have from
Tanzania. The overall colour is darker and the shape of the petiole is
quite distinct.
TL 2.0 mm; head slightly longer
than wide, laterally convex; eyes flat; promesonotum convex; propodeal
spines a little longer than one-third their basal separation;
propodeum laterally bordered; petiole trapezoidal, with the anterior
and posterior angles dentate, subtended by an almost horizontal tooth;
dark brown, gaster brown-black, appendages brownish-red.

Crematogaster (Decacrema) species T³
Nigeria specimens. WORKER. TL 1.87 mm, HL 0.54,
HW 0.50, SL 0.36, PW 0.31 (Taylor, 1979: 21)
Colour orange, darkening posteriorly, gastral apex near black. Shiny,
unsculptured. Erect hairs fine and sparse. Pilosity very sparse on the
head and gaster. Alitrunk convex in profile, metanotal grove slightly
impressed, propodeal spines long, acute and upturned. Petiole
trapezoidal in dorsal view, corners acute, subpetiolar spine relatively
long with a rounded apex. Postpetiole with a slight longitudinal
depression.
In Nigeria, it nests in dead wood and under dry
bark. Occasionally found on cocoa (rare) and native shrubs, also on
coffee. Entwistle (1972) lists a Crematogaster (Decacrema)
species as among the ants which tend mealybugs in Nigeria but he gives
no other details.
Previously thought by me to be Crematogaster
petiolidens.
