A new species of Macrelmis Motschulsky, 1859 (Coleoptera: Elmidae) and new records of Elmidae from Roraima State, northern Brazil

Abstract

A new species of Macrelmis Motschulsky, 1859 (Macrelmis rodrigoi sp. nov.) is described and illustrated based on specimens found in mountainous areas of the northern Roraima State, Brazil. Pagelmis amazonica Spangler, 1981, Potamophilops bostrychophallus Maier, 2013 and Stegoelmis geayi Spangler, 1990 are recorded in Brazil for the first time and new records for Gyrelmis obesa Hinton, 1940, Macrelmis thorpei Hinton, 1945 and Neolimnius palpalis Hinton, 1939 are presented.

La familia Elmidae (Insecta: Coleoptera: Byrrhoidea) en Colombia: riqueza taxonómica y distribución

“…En la región neotropical se han descrito 48 géneros de Elmidae y 43 en Suramérica, siendo Colombia el país con mayor registro de géneros, seguido por Venezuela con 27 (Spangler, 1990;Jäch, et al, 2016;Barr, 2019;Polizei & Barclay, 2019 b), Brasil con 25 (Segura, et al, 2011, Almeida, et al, 2020, Perú con 22 (Springer & Acosta-Rivas, 2003;Shepard & Chaboo, 2015;Jäch, et al, 2016;Barr, 2018) y Guayana Francesa y Ecuador con 21 (Monte & Mascagni, 2012;Jäch, et al, 2016;Barr, 2018;Ciampor, et al, 2019;Shepard, et al, 2020). A nivel panamericano, Estados Unidos también cuenta con 29 géneros registrados, de los cuales Ampumixis, Atractelmis, Bryelmis, Rhizelmis y Typhloelmis son endémicos de ese territorio (Jäch, et al, 2016;Barr, et al, 2015).…”

“…Es un género ampliamente distribuido en América, desde Estados Unidos hasta Argentina, y cuenta con 53 especies descritas, dos de ellas con material tipo de Colombia, pero sin localidad definida (Brown, 1984;Passos, et al, 2015;Almeida, et al, 2020) y otras tres registradas en los departamentos de Antioquia y Tolima (Hincapié-Montoya & Uribe-Soto, 2018, 2019; Lozano-Bravo, et al, 2018). Es uno de los géneros con más especies del Neotrópico, junto con Cylloepus y Neoelmis (Manzo, 2013;Jäch, et al, 2016).…”

Spanglerelmis, a new genus of Elmidae (Insecta: Coleoptera) from Brazil with new species and biological notes

“…The knowledge of Neotropical Elmidae has increased in recent years with the description of several new species (Polizei & Barclay 2018, 2019a, 2019bLinský et al 2019Linský et al , 2021Polizei et al 2020aPolizei et al , 2020bČiampor et al 2021), and two new genera: Amazonopsis Barr, 2018 from Peru, Venezuela, and French Guiana; and Ictelmis Čiampor, Linský & Čiamporová-Zaťovičová reported from Ecuador. In Brazil, although new species have been regularly described in recent years (Polizei 2018a(Polizei , 2018bAlmeida et al 2020;Polizei et al 2020b;Polizei & Fernandes 2020;Polizei & Hamada 2021), the last genera, Tolmerelmis Hinton, 1972 andTyletelmis (Hinton, 1972), were described approximately 50 years ago.…”

“…Therefore, the current richness of Elmidae in Brazil is likely underestimated. Fortunately, in recent years the sampling effort in different Brazilian regions has increased, resulting in both ecological (Segura et al 2012;Braun et al 2014Braun et al , 2018a and taxonomic studies (Polizei 2018a;Almeida et al 2020;Polizei et al 2020aPolizei et al , 2020bPolizei & Fernandes 2020;Polizei & Hamada 2021), which have expanded knowledge about Elmidae.…”

“…Thus, it is highly likely that the richness of species of Elmidae within Brazil has been strongly underestimated. Despite this, knowledge has advanced, including the description of new species and the development of taxonomic keys (Fernandes et al 2011;Fernandes & Hamada 2012;Sampaio et al 2012;Barbosa et al 2013;Ferreira-Jr et al 2014;Passos et al 2015;Polizei 2018aPolizei , 2018bPolizei & Barclay 2018, 2019a, 2019bLinský et al 2019;Almeida et al 2020;Polizei et al 2020aPolizei et al , 2020bPolizei & Fernandes 2020).…”
