Centromyrmex hamulatus (Karavaiev) 

Typhloteras hamulatum Karavaiev, 1925: 129  (worker). [Combination in Centromyrmex  by Brown, 1953: 8. Description of queen and male: Karavaiev, 1926: 419.]

This is currently the sole member of the C. hamulatus  group and is quite widespread in the Malesian region. In morphological terms hamulatus  forms a striking intermediary between the Old World species of the bequaerti  group and the feae  group, but it also has several apomorphies of its own.

i. Characters shared between workers of hamulatus  and bequaerti  group: shape of head capsule; close proximity of frontal lobes medially; non-swollen protibiae; lack of hypertrophy of procoxae; lack of pronotal margination; elongate slit-like orifice of propodeal spiracle; presence of spiniform metasternal process.

ii. Characters shared between workers of hamulatus  and feae  group: structure of mandible; dorsal outline shape of mesonotum and propodeum; position of propodeal spiracle; bilaterally compressed propodeal dorsum; petiole anteriorly pedunculate; form of prora; distribution of setae; monomorphic worker caste.

iii. Characters of hamulatus  workers not shared by bequaerti  or feae  groups: mesotibia with 1 spur; metatibia with 1 spur; subpetiolar process a pair of stout teeth; mesopleuron with a weak transverse sulcus; constriction of second gastral segment strong and conspicuously cross-ribbed.
