RESUMEN
We describe a new species of Eulimnadia from the Caribbean using fresh material from the island of St Thomas. Originally reported in 2003 as a Eulimnadia cf. texana (Packard, 1871) based on egg morphology, this species egg distinctly differs from E. texana by the number of lateral grooves and by the single domed end.
RESUMEN
As part of preparation for identification keys to the branchiopod crustaceans of the Neotropical Region, we re-examined many species of Anostraca that appeared to be closely related. Our examination caused us to re-evaluate the status and relationship of two branchinectid species.

Branchinecta uruguayensis, a new species of fairy shrimp, is described from a single seasonally astatic aquatic habitat in coastal Uruguay. This is the first record of an anostracan from the nation of Uruguay. Male B. uruguayensis n. sp. are separated from other Branchinecta species by the form of the second antennae. Branchinecta uruguayensis n. sp. share the distal antennomere lobiform projection with B. papillata Rogers, De los Rios, & Zúñiga, 2008 and B. achalensis César, 1985. Branchinecta uruguayensis n. sp. females are readily separated from all other Branchinecta by the presence of posteriolateral thoracic spines and lateral crenulations on the first abdomen segment margins. A key is provided to the Branchinectidae of South America.
