Aptychopsis cylindrothecia is an endemic and poorly known species in the country. In the present study, information on its taxonomy, morphology, and ecology is presented. Taxonomic and morphological data were obtained through the analysis of nomenclatural types. For being a little known species with few records, distribution models were used to estimate areas with greater environmental suitability and locate new populations, using MaxEnt. The IUCN conservation status such as the extension of occurrence (EOO) and area of occupancy (AOO) was performed using R software. Two datasets are modeling in this research. The first dataset was using the primarily specimens deposited in herbarium collection. The results of on dataset, provided preliminary data on the most suitable places for its occurrence, thus making it possible to find new populations. The second dataset was performed using the data set1 and new populations were found. Currently, the AOO estimated 52km² and EOO 827.710 km², both estimates classified as Least Concern status. The models indicate the phytophysiognomies of Atlantic Forest in Southwest region of Brazil, preferentially high forest, such as the appropriate areas for the most probable occurrence of the A. cylindrothecia. These results could serve as guides for future survey expeditions, understand their ecology, and morphology.
