An updated checklist of the freshwater decapod species of Puerto Rico is presented based on records of shrimp and crab species whose presence has been confirmed in Puerto Rico as a result of extensive field collections, examination of carcinological collections, literature review, and personal communications from researchers. The freshwater decapods fauna of Puerto Rico consists of 18 species o...

Mantis shrimps (Crustacea: Stomatopoda) are rather rare in the fossil record. Nineteen species have been assigned to Squillidae, of which 12 species have been recorded from the Miocene. We describe herein a squillid, Squilla taulinanus n. sp., from the Miocene of Taulignan, south-eastern France. The exceptionally well-preserved specimen is remarkable in apparently having abdominal somites 5–6 c...

Laevicaudatan branchiopods, also called ‘smooth clam shrimps’ or ’pea shrimps’, are rare crustaceans found exclusively in temporary, small freshwater bodies, which stay dry most of the year. Only 42 laevicaudatan species have been described so far, 90% belong to genus Lynceus. The first multilocus phylogeny group is provided here, based on 15 Lynceus from North and South America, Europe, Africa...

The present study is the first revision of the western Atlantic peppermint shrimp complex Lysmata wurdemanni (Gibbes). Lysmata wurdemanni, originally described from Florida and South Carolina, is redescribed. Gibbes' types of L. wurdemanni are considered as lost, therefore, a neotype is selected from specimens collected near Key West, Florida. Lysmata rathbunae Chace is rediagnosed; the localit...

This study evaluated the effect of thermal fluctuation on susceptibility Pacific White Shrimp to infection with Spot Syndrome Virus (WSSV). The shrimps were divided into two treatments: infected and subjected from 28°C 18°C for 48 h back (TF); kept at a constant temperature (CT).
