This and the previous species are similar, including the size of the genital apparatus, but few characters are distinctive (Pl. 15: Fig. 5–6): i) the tergal lobe in C. claudia sp. nov. is not differentiated, while in C. mirna sp. nov. there is a protrusion ventro-posteriorly (Pl. 15: Fig. 6; see upper arrow), ii) the valvae in C. claudia sp. nov. are clearly more robust, and iii) the pseudotegumen are not reinforced anteriorly in C. claudia sp. nov., but reinforced in C. mirna sp. nov. (Pl. 15: Figs 6; see lower arrow).
