Comments. Coelinius canastra was described from a single female specimen collected in 2009. Here we report the morphological variation from two additional specimens, one male and one female, both collected in 2019 from rupestrian grassland physiognomies, near to the area where it was collected the holotype (Chapadão da Canastra).
