A redescription of a common euryhaline cumacean from southern Brazil: Diastylis sympterygiae Bacescu & Queiroz, 1985 (Crustacea: Cumacea)

Diastylis sympterygiae Bacescu & Queiroz (1985) has been reported in many ecological studies conducted in the Patos Lagoon, southern Brazil. However, the original description of this species is based on damaged specimens from stomach contents of rays, and therefore insufficient for a confident identification. In the present contribution, based on a large number of well-preserved specimens now available from the type locality area, the description of this common euryhaline species is completed and its range of distribution as far north as Sao Paulo is extended.Red de Macrouniversidades Publicas de America Latina y el CaribeRed de Macrouniversidades Publicas de America Latina y el CaribeGrupo SantanderGrupo SantanderFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)[2008/55842-8]Consejo Nacional de Investigaciones Cientificas y Tecnicas, Argentina (CONICET)Consejo Nacional de Investigaciones Cientificas y Tecnicas, Argentina (CONICET)Universidad de Buenos Aires UBACyT, ArgentinaUniversidad de Buenos Aires (UBACyT)[X-190], Argentin
