The state of the art of Xyalidae (Nematoda, Monhysterida) with reference to the Brazilian records

“…The first records of Xyalidae along Brazilian coastline were done by Sebastian Gerlach (Gerlach , 1956a(Gerlach , b, 1957a Bik et al 2009), the large majority (32 species) were recorded at one region. This would support high levels of endemism along the Brazilian coast.…”
