New record of the Six-holed Keyhole Urchin, Leodia sexiesperforata (Leske, 1778) (Clypeasteroida, Mellitidae), from the Brazilian coast, with an updated distribution map

Abstract

A new record of Leodia sexiesperforata is reported from the coast of Rio Grande do Norte state, northeastern Brazil. An updated distribution map based on data collected from literature, museums, and scientific collections is also presented. This new report fills a distribution gap on the coast of northeastern Brazil. Leodia sexiesperforata has a continuous range between the states of Ceará and Alagoas.

New records, extended and updated geographic distribution of the South American native antlion Dimares elegans (Perty, 1833) (Neuroptera, Myrmeleontidae)

“…In addition, the specimen records in the iNaturalist were analyzed by the authors of the present study together with the observation of the primarily collected specimens and the compared material. Records with inaccurate taxonomy, invalid geographic coordinates, or missing information from the collections and institutions to which they belonged, were disregarded as proposed by Alencar et al (2017).…”

“…Then, confirmation of the coordinate was performed in the Google Earth satellite mapping software considering the geographic coordinate system in WGS84. The procedures for compiling and validating secondary data and estimating geographic coordinates by records with only a description of the locality followed the procedure proposed by Alencar et al (2017).…”

Niche modeling remarks of Luidia senegalensis (Lamarck, 1816) (Asteroidea, Luidiidae) after 30 years of its first capture in the northeastern Brazilian coast

“…In Porto do Mangue, the sampling was quarterly, according to rainy and dry seasons determined by a historical compilation of rainfall data in 10 years (1992-2012) (EMPARN -Empresa de Pesquisa Agropecuária do Rio Grande do Norte, Brazil). Therefore, there were two samplings by season (dry, March-May and June-August; and rainy, September-November and December-February) by year (Alencar et al, 2017). Sampling was occasional in Ponta do Mel through escorting a beach trawling in August 2015.…”

“…Data were evaluated regarding reliability and, when needed, some were excluded due to information repetition and doubtful locations. All species records were analyzed according to Alencar et al (2017) procedures.…”

“…The continental shelf of Rio Grande do Norte State is still underexplored regarding its biodiversity, showing information gaps. Over the past years, new occurrences for many benthic organisms have been reported (Alencar et al, 2013(Alencar et al, , 2017Manso et al, 2014;Gondim et al, 2015;Moraes et al, 2015) and new ecological interactions (Alencar et al, 2014), which shows that the development of scientific research involving the local marine biodiversity is required in the state. More studies and monitoring programs focused on marine faunal biodiversity are essential subsidies for future assessment plans and reevaluation of L. senegalensis threat status, especially on the coast of northeast Brazil, where macrofaunal diversity knowledge is scarce and needs more investment when compared to south and southeast Brazilian regions.…”
