Morphological review of the freshwater fairy shrimp Dendrocephalus brasiliensis Pesta, 1921 (Anostraca: Thamnocephalidae)

Abstract

Information concerning the morphology of Dendrocephalus brasiliensis Pesta, 1921 is currently fragmented. Th is study reviewed the morphological structures described previously and new features (e.g., antenna-like structures and gonopod). We review the distribution of this species and also expand the geographic distribution of D. brasiliensis in the state of Alagoas. Th e specimens were obtained from fi sh-breeding tanks in Porto Real do Colégio, Alagoas, Brazil, in November 2012. Several morphological structures of D.

“…Other studied specimens were identified following adapted literature (Pereira 1983(Pereira , 1984Pereira & Belk 1987;Pereira & Ruiz 1995;Rabet & Thiéry 1996;Rabet 2006;Rogers et al 2012;Hirose et al 2015;Rogers & Volcan 2016;Barros-Alves et al 2016).…”

“…From the studied samples and the literature (Pesta 1921;Lutz 1929;Lemos de Castro & Lima 1986;Rabet & Thiéry 1996;Rabet 2006;Chaves et al 2011;Rogers et al 2012;Hirose et al 2015;Rogers & Volcan 2016;Barros-Alves et al 2016), we analysed the morphological characters shared by the frontal appendage and the limbs of all Brazilian species of Dendrocephalus and summarized these observations in Tables 1-3. All the known locations of Dendrocephalus are indicated on the map of Brazil (Fig.…”

“…In the future, we believe that genetic studies will be very useful in better delineating species of Dendrocephalus, especially widely distributed species such as D. brasiliensis (see Barros-Alves et al 2016), to detect possible cryptic species as well as to better understand the diversification of species with restricted distributions, such as D. aranai sp. nov. or D. xikrini sp.…”
