Etymology
The species is named after the Semira River which is close to the type locality.

Remarks
Comparison with similar species
The male genitalia of C. semira sp. nov., C. malava sp. nov. and C. eaerendili sp. nov. are very similar, but the species can be distinguished by non-genitalia characters. The head and the mesosoma are dark brown in C. semira and light brown or brown in C. malava and C. eaerendili. The flagellum is brown in C. semira and light brown or light brown-yellowish in C. malava and C. eaerendili. The scape is distinctly longer in comparison to the pedicel in C. semira, and the anteromedian projection of the metanoto-propodeo-metapecto-mesopectal complex is exceeding the end of the mesosoma in C. semira, whereas it is extending only to the end of the mesosoma in C. malava and C. eaerendili.
Condition of type material
In the holotype, the right F9 is deformed and the left hind wing is missing. The posterior half of the metasoma is deformed, thus the body length measurement is not precise.
