Mann also described C. schmeltzi var. loloma from Lau, and C. schmeltzi subsp. troterri from Taveuni. Here we are synonymizing C. loloma with C. schmeltzi, and C. trotteri withC. kadi. The propodeum of C. trotteri forms a distinct posterior tooth that is distinctly different from any of the material examined from Viti Levu or Gau, but the difference in pilosity as discussed by Mann is far more subtle. The propodeum variation found in C. loloma varies from being nearly identical to that of C. kadi from Viti Levu and Gau to a very close approximation of C. trotteri from Taveuni. If the various forms occurred in sympatry, it would be easier to justify raising each of them to species. However, the lack of sympatry combined with a demonstrated tendency towards morphological plasticity makes the matter more complicated, and thus the tentative decision to consider them geographic variants of a single species.
Even with the expanded definition of C. kadi, as proposed here, distinct differences can separate both the majors and minors from the larger C. schmeltzi. The minor workers ofC. schmeltzi are relatively large with the posterolateral corners of the head acutely angled, and the entire leg from coxa to femur is uniformly light brown to black. The minor workers of C. kadi are relatively small, the posterolateral corners of the head are evenly rounded, and the trochanter and distal portion of the coxa is a pale yellow that contrasts with the darker brown of the tibia and basal portion of the coxa. The major workers of C. schmeltzi are also larger, exhibit the same uniform color from coxa to the tibia as in seen in the minors, and series of strong well-defined longitudinal carinae are present on both the cheeks and clypeus. The majors of C. kadi (examined only from the Viti Levu and Gau population) are smaller, possess the same contrasting trochanters, and weak poorly defined carinulae are present on the cheeks and clypeus.
