“…Ophiocoma echinata from other localities occurred at depths from 0.1 to 49 m, occurring on substrates such as coral and sandstone reefs. In Brazil: Bahia (Tommasi, 1970; Manso et al ., 2008), Ceará (Albuquerque, 1986), Pernambuco (Tommasi, 1970; Lima and Fernandes, 2009), Alagoas (Miranda et al ., 2012) and Paraíba (Rathbun, 1879).

“…echinata was the only remaining Ophiocoma species recorded from the Brazilian coast so far, whose distribution ranges from Florida (~20°N) to Bahia (~12°S) (Tommasi, 1970; Manso, 1993). Localities along the Brazilian coast include the states of Ceará (Albuquerque, 1986), Paraíba (Rathbun, 1879), Pernambuco (Tommasi, 1970; Lima and Fernandes, 2009), Alagoas (Miranda et al ., 2012) and Bahia (Tommasi, 1970; Manso et al ., 2008).…”

The brittle stars of the family Ophiocomidae inhabit shallow waters and coral reefs of tropical regions. The species of Ophiocoma are difficult to identify due to high morphological variation, especially when different stages of development are observed. Here, based on morphological analyses, two Brazilian morphotypes of Ophiocoma were studied and characterized, Ophiocoma sp. NB (Northeastern Brazil) and Ophiocoma sp. TMV (Trindade and Martin Vaz Archipelago), and subsequently thoroughly analysed to confirm whether they were the same species or not. After the morphological studies, including external morphology, morphometry and microstructural characters, and analysis of molecular data, involving the 16S gene, it was concluded that Ophiocoma sp. NB and Ophiocoma sp. TMV do not correspond to the same species, the first being identified as Ophiocoma echinata (Lamarck, 1816) and the latter being a new species. This new species is characterized by two tentacle scales on the first arm segment and then one on all following segments, and the dorsalmost arm spines are robust and rounded, as wide as long or almost as wide as long.

ResumoMacrófitas aquáticas são organismos visíveis a olho nu e que apresentam partes fotossinteticamente ativas, permanente a temporariamente submersas ou flutuantes. Dada a relevância ecológica e fisionômica do grupo, este estudo objetivou determinar a riqueza de macrófitas aquáticas do Parque Estadual de Itaúnas, Espírito Santo, Brasil, e suas relações florísticas com outras sete áreas na Floresta Atlântica. Foram encontradas 66 espécies, 48 gêneros e 31 famílias de macrófitas aquáticas para o PEI, dessas, duas constituem registros inéditos para o Brasil (Sesbania herbacea e Utricularia biloba), cinco para o estado (Ipomoea bahiensis, Ludwigia cf. filiformis, Ludwigia hyssopifolia, Mollugo verticillata, Paspalum repens) e 49 novas ocorrências para o PEI. A grande maioria constitui-se por angiospermas e apenas três são pertencentes ao grupo das Samambaias e Licófitas. Os resultados da análise de agrupamento revelaram dois grupos, onde um é constituído exclusivamente por áreas cujas fitofisionomias são de restinga enquanto o outro é formado por áreas de fitofisionomias distintas. Dessa maneira, os novos registros aliados a baixa similaridade da composição de espécies, tornam evidente a importância da área para a conservação de macrófitas aquáticas dentro da Floresta Atlântica. Palavras-chave: florística, neotrópicos, plantas aquáticas, similaridade. AbstractMacrophytes are organisms that have active photosynthetic parts and may be permanently or seasonally submerged, or floating. Given the ecological and physiognomic relevance of the group, this study aimed to determine the richness of aquatic plants from the Parque Estadual de Itaúnas (PEI), Espírito Santo, Brazil, and its floristic links with other areas in the Atlantic Forest. A total of 66 species, 48 genera and 31 families of aquatic macrophytes were found for PEI, of which two are unpublished records for Brazil (Sesbania herbacea and Utricularia biloba), five for the state (Ipomoea bahiensis, Ludwigia cf filiformis, Ludwigia hyssopifolia, Mollugo verticillata, Paspalum repens) and 49 new occurrences for PEI. Most of species are represented by angiosperms and only three species belong to Ferns and Licophytes. The similarity analysis results revealed two groups, one formed exclusively by areas considered as "restingas" while another is composed by areas with different plant physiognomies. Thus, new records allied to the low similarity of species composition make evident the importance of the area for the conservation of aquatic macrophytes from the Atlantic Forest. Key words: floristics, neotropics, aquatic plants, similarity.

We updated the first checklist of aquatic macrophytes from Northeast Brazil (First Flora), which included data collected up to 2010, with a new checklist based on data from works published between 2011 and 2017 (New Flora). Together, these checklists record 637 species of 89 families, with an emphasis on strictly amphibious or emergent species, with 392 and 115 species, respectively. We found differences in observed richness between New Flora and First Flora, with an increase of 106 species in the New Flora. The rarefaction curve shows that a considerable increase in collection effort is necessary to determine the aquatic flora of the studied region. From the compiled data, we suggest new perspectives for floristic inventories of aquatic macrophytes, highlighting the prioritization of poorly studied areas; the exploration of ecological information of the species (e.g., endemism, rarity, threat of extinction or invasive potential); and the promotion of projects on a regional scale.
