NOTES ON SOME ALPHEID SHRIMPS FROM THE COAST OF PARÁ STATE: NEW RECORD AND FILLING DISTRIBUTION GAPS

Abstract

The objective of this study is to report new occurrence of snapping shrimps Alpheus chacei Carvacho, 1979 on the coast of Pará State, Northern region of Brazil, contribute to the knowledge of their zoogeography, since there was a divergence between their upper limit of distribution. A. chacei was recorded in the Urindeua river in August and December of 2013. It is verified that, after a bibliographic review, records of 14 alfeídeos in the Pará State, corresponding to three genera: Alpheus (seven spp.), Synalpheus Spence Bate, 1888 (six spp.) and Automate Man, 1888 (one sp.). This study contributes to the knowledge of the decapod fauna occurring in the state, but there is a need for more samplings in order to register new species, given the high diversity of (unregistered) species of the Alpheidae family worldwide.
