New records of decapod crustaceans from the coast of Sergipe state, Brazil

Abstract

The objective of this study is to report seven decapod crustacean species for the first time from Sergipe state, northeastern Brazil. The specimens were sampled from January 2012 to June 2015, on continental shelf and estuaries. Alpheus buckupi,Synalpheus ul, Lysmata bahia, L. cf. intermedia, Paguristes tortugae, Macrocoeloma laevigatum and Pilumnoides coelhoi are reported. This study records fill gaps in the geographical distribution of these decapods that have previous records for adjacent areas.

Lysmata arvoredensisnov. sp. a new species of shrimp from the south coast of Brazil with a key to species ofLysmata(Caridea: Lysmatidae) recorded in the southwestern Atlantic

“…These specimens were collected and identified by Thais P. Macedo and are deposited at the Zoological Collection of the UFSC (LCP/UFSC- 113). The color pattern exhibited by other species present in Brazil was taken from Gordon (1935) , Hayashi (1975) , D’Acoz (2000) , Rhyne & Lin (2006) , Coelho et al (2006) , Baeza (2010) , Okuno & Fiedler (2010) , Fiedler et al (2010) , Laubenheimer & Rhyne (2010) , Rhyne, Calado & Dos Santos (2012) , Soledade et al (2013) , Barros-Alves et al (2015) , Giraldes & Freire (2015) , Kassuga, Diele & Hostim-Silva (2015) , and Terossi et al (2018) . It must be highlighted that the color pattern of most species likely becomes less intense when specimens are subject to high intensity illumination ( Wear & Holthuis, 1977 ; Calvo et al, 2016 ).…”

Refining southwestern Atlantic peppermint shrimp biodiversity: description of a new species ofLysmata(Decapoda: Lysmatidae) using an integrative systematic approach

“…This new species is close (based on morphology, genetics, and colour pattern) to the eastern Pacific L. holthuisi , and both western Atlantic L. intermedia and L. jundalini . Lysmata intermedia was described from USA (Florida) and has been extensively recorded along the Brazilian coast (Ceará to São Paulo; Christoffersen, 1980; Ramos-Porto et al ., 1995; Almeida et al ., 2007; Santos et al ., 2012; Barros-Alves et al ., 2015, 2016; Pachelle et al ., 2016, 2020). Lysmata jundalini was described from Puerto Rico and first recorded off the Brazilian coast (Couves Island, São Paulo) in 2018 after reanalysis of material previously identified as L. cf.…”

“…Historically, L . intermedia and L. moorei were the only two long-branch species inhabiting the southwestern Atlantic (Christoffersen, 1980, 1998; Ramos-Porto et al ., 1995; Coelho Filho, 2006; Almeida et al ., 2007; Santos et al ., 2012; Barros-Alves et al ., 2015, 2016; Pachelle et al ., 2016, 2020). Recently, an individual collected along the coast of Espírito Santo, southeastern Brazil, was tentatively identified as L. jundalini after detailed morphological analysis, which increases the number of long-branch species in the region (Pachelle et al ., 2020).…”

Two new marine hermit crabs allied with the Paguristes tortugae complex (Crustacea: Decapoda: Anomura) from the western Atlantic

“…Numerous checklists, observational accounts, ecological studies, and taxonomic keys do not address details of coloration or morphology among the specimens they designate as P. tortugae s.l. (Schmitt 1935;Wass 1955;Provenzano 1961;Soto 1980;Holmquist 1989;Martinez-Iglesias & Gomez 1989;Mantelatto & Sousa 2000;Majon-Cabezas et al 2002;Mantelatto & Garcia 2002a, 2002b, 2002cRaz-Guzman et al 2004;Rahayu 2005;Tagliafico et al 2005;Barros-Alves et al 2015;Lemaitre & Tavares 2015;Poupin 2018). Thus, our herein reported synonymies applicable to P. karenae n. sp.…”
