The name is from the Latin (angarius "mounted courier") after the tendency to ride weevils.

Its divergence from C. elegans is similar to the distance between humans and fish.

C. castelli is its closest relative, and the two species can produce F1 hybrids.

[3] C. angaria was isolated in Trinidad and Florida, found in association with palm and sugarcane weevils, Rhynchophorus palmarum and Metamasius hemipterus.

[3] This species groups with C. castelli in the 'Drosophilae' supergroup in phylogenetic studies.
