Updated checklist of estuarine caridean shrimps (Decapoda: Caridea) from the southern region of Laguna Madre, Tamaulipas, Mexico, with new records and a key for taxonomic identification

Abstract

We provide an updated list of the caridean shrimp species from the southern region of the Laguna Madre, Tamaulipas, Mexico, along with a key for taxonomic identification. The survey was conducted in 3 sites during 3 temporal seasons. A total of 2,989 specimens were collected belonging to 12 species, 6 genera, and to the following 4 families: Alpheidae, Hippolytidae, Palaemonidae, and Processidae. Hippolytidae was the most abundant family, followed by Palaemonidae, Alpheidae, and Processidae. The hippolytid Hippolyte obliquimanus Dana, 1852, the palaemonids Palaemon floridanus Chace, 1942, and P. northropi (Rankin, 1898), and the alpheid Alpheus cf. packardii Kingsley, 1880 represent new records for the Laguna Madre and selected areas of the Gulf of Mexico.

Delimitation of sympatric Palaemon (Decapoda, Palaemonidae) species of the Laguna Madre, Mexico

“…However, two specimens identified from a morphological basis as P. pugio and P. mundusnovus were observed exhibiting this feature. Similarly, other American species with two teeth in the carapace are P. paivai , P. ritteri , P. schmitti and P. northropi , the latter having been recently reported in Laguna Madre of Tamaulipas by Herrera‐Barquín, Leija‐Tristán, and Favela‐Lara (), differentiating it from P. vulgaris , P. pugio and P. mundusnovus , as teeth are not divided regularly on the entire rostrum and a mandibular palp is present, among other characteristics, disclaiming that it is a fourth species that may be confused by its sympatric distribution. Although this characteristic is included in the aggregate dorsal teeth of the rostrum in most studies, we do not rule out that individually it might be a shared feature among some Palaemon species with phylogenetic utility.…”
