Ten species fall into these three species groups: exigua trigonidiine genus Anaxipha (OSFO 2013), but Otte & Perez-Gelabert group (exigua Say, scia Hebard and n. spp. thomasi, tinnulacita, tinnulenta, (2009, p. 127) suggest that the genus is "in serious need of revi- and tinnula); delicatula group (delicatula Scudder and vernalis n. sp.); litarena sion" and that "the taxonomy of the Trigonidiinae as a whole is in a group (litarena Fulton and rosamacula n.sp.).
