Additionally we made a comparison of granulation pattern of the carapace of C. ruana sp. nov., C. balsasensis, C. infamatus, C. limpidus, and C. tecomanus using images in UV light. Differences in the patterns of granulation of central median carinae(cmc) and central lateral carinae (clc) as well as in the granulation located above the posterior transverse furrow (ptf) can be appreciated between species (Fig. 8).
