Cyrnellus minimus Banks 1913: 88   (original description); Flint 1967: 5 (redescription of male lectotype); Flint 1971: 29 (as synonym of C. fraternus   ); Holzenthal & Calor 2017: 419 (catalogue, as synonym of C. fraternus   ).

Diagnosis. Cyrnellus minimus   is similar to C. fraternus   , C. marginalis   , C. boliviensis   n. sp., and C. zapateriensis   . Cyrnellus minimus   and C. zapateriensis   are most similar; these two species have similar subapicomesal spines on the inferior appendages, but with distinct insertion: subapical in C. minimus   ( Fig. 4B View FIGURE 4 , ap) but more nearly apical in C. zapateriensis   . The internal lobe of each inferior appendage is triangular in C. minimus   and rounded in C. zapateriensis   . Another difference from most of the other species is the near fusion of the posterior arms of the dorsal phallic sclerite ( Figs 4C, 4D View FIGURE 4 , ds). This character is also observed in C. ulmeri   , this latter species being distinguished by the presence of a second subapicomesal spine on each inferior appendage.
