Males of  Otoniela lupercioi  sp. nov.resemble those  O. chica  sp. nov.by having a robust, subtriangular ventral tegular projection ( Fig. 6C). They differ by the large base of the ventral tegular projection, smaller retrolateral patellar apophysis and truncated embolar basal apophysis ( Figs 4D, E; 5G, H). Narrow base of ventral tegular projection and oblique sperm duct in  O. chica  sp. nov.( Figs 6C, E). Females of  Otoniela lupercioi  sp. nov.are similar to those of  O. chica  sp. nov.by the ample epigynal atrium and rounded, large spermathecae ( Figs 5I; 6F, G). They differ by the arc-shaped posterior border ( Fig. 4G). Posterior lateral borders sub-rectangular and a anterior invagination in  O. chica  sp. nov.( Figs 6G, H).   Description. Male(IBSP 29716).
