This is currently the sole member of the C. hamulatusHNS group and is quite widespread in the Malesian region. In morphological terms hamulatusHNS forms a striking intermediary between the Old World species of the bequaertiHNS group and the feaeHNS group, but it also has several apomorphies of its own.
i. Characters shared between workers of hamulatusHNS and bequaertiHNS 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 hamulatusHNS and feaeHNS 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 hamulatusHNS workers not shared by bequaertiHNS or feaeHNS 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.
