TABLE 6. Comparison of morphological characters of selected species in Caymanostellidae. Descriptions of new species (except R, r and R/r) are based on shared characters among adult specimens. Crinitostella is synonymized here as Caymanostella. *Not discernable according to Dilman et al. (2022), but visible in Fig. 2E of Dilman et al. (2022) and Rowe (1989).
