In this study, the area of occurrence of the species is reported to extend to a Cerrado area in Maranhão state, northeastern Brazil. Digital collections from Brazilian and international herbaria were consulted. The species original description is complemented herein with illustrations and information on the species phenology, ecology, and conservation status. The discovery of D. racemosa in Maranhão demonstrates the importance of floristic studies and the need for further research of this nature in that Brazilian state.

Este grupo é constituído por dois gêneros monoespecíficos, Eithea (E. blumenavia) e Eusarcops (E. reticulata), sendo que neste artigo é proposto o restabelecimento do último. São discutidas as relações morfológicas e filogenéticas dos táxons deste grupo dentre as Hippeastrinae, apresentando-se uma chave para identificação dos gêneros desta subtribo que ocorrem no Brasil.

Descriptions, illustrations and data on etymology, ecology, conservation status, distribution and habitat of the species are provided. The taxonomic placement of the genus in morphological and phylogenetic aspects is discussed.

Data one its habitat, cology, geographic distribution is provided and its threat status is evaluated according to IUCN criteria. The new species has morphological affinity with H. sanctaecatharinae and H. breviflorum, the last one has not been correctly typified up to date, being lectotyped here to correctly define the circumscription of this taxonomic entity in comparison to the new species.

ABSTRACT [Taxonomic-nomenclatural disambiguation and typification of species of the Sealyana group (Amaryllidaceae, Amaryllidoideae), and their synonyms]. A nomenclatural revision of the taxa belonging to the Sealyana group is provided and typifications proposed. This group consists of two monospecific genera, Eithea (E. blumenavia) and Eusarcops (E. reticulata), and in this article the reestablishment of the latter is proposed. Morphological and Phylogenetic relationships of the taxa of this group among the Hippeastrinae are discussed, presenting a key for identification of the genera of this subtribe that occur in Brazil.
