Decapod crustaceans from the state of Ceará, northeastern Brazil: an updated checklist of marine and estuarine species, with 23 new records 

Abstract

The present study is the first major assessment of the marine decapod fauna of Ceará, northeastern Brazil, since contributions of J. Fausto-Filho in the 1960s-1970s. A fully updated checklist of all decapod crustaceans occurring in marine and estuarine habitats of Ceará is provided, based on literature records, specimens held in two carcinological collections of the Universidade Federal do Ceará (UFC), and material collected mainly by the authors between 2011 and 2014. A total of 337 decapod species are listed, distributed among the following taxa: Achelata (8 species), Anomura (42 species), Astacidea (1 species), Axiidea (11 species), Brachyura (162 species), Caridea (83 species), Dendrobranchiata (20 species), Gebiidea (9 species), and Stenopodidea (1 species). Among them, 23 species represent new records for Ceará, with 14 species, viz. Alpheus peasei (Armstrong, 1940), A. thomasi Hendrix & Gore, 1973, Ambidexter symmetricus Manning & Chace, 1971, Axianassa australis Rodrigues & Shimizu, 1992, Biffarius biformis (Biffar, 1971), B. fragilis (Biffar, 1970), Leptalpheus axianassae Dworschak & Coelho, 1999, L. forceps Williams, 1965, Lysmata bahia Rhyne & Lin, 2006, L. intermedia (Kingsley, 1878), Merhippolyte americana Holthuis, 1961, Neocallichirus maryae Karasawa, 2004, Ogyrides hayi Williams, 1981, and Typton carneus Holthuis, 1951, now having Ceará as the northern-most limit in their distribution range along the Brazilian coastline. One shrimp species, Lysmata lipkei Okuno & Fiedler, 2010, which was also found in the state of Rio Grande do Norte, possibly represents an invasive taxon in Brazil and the western Atlantic, originating from the Indo-West Pacific. Alpheus buckupi Almeida, Terossi, Araújo-Silva & Mantelatto, 2013, previously recorded from Ceará based on a colour photograph, is confirmed from this state, with specimens from several new localities. A few doubtful records from Ceará are briefly discussed. Colour photographs are provided for most of the taxa newly recorded from Ceará; some species are illustrated in colour for the first time.

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

“…intermedia (Kingsley, 1878) ( Rhyne, Calado & Dos Santos, 2012 ; Terossi et al, 2018 ); the Indo-Pacific L. vittata (Stimpson, 1860) improperly described as a new species (i.e., L. rauli Laubenheimer & Rhyne, 2010 ) ( Laubenheimer & Rhyne, 2010 ; Soledade et al, 2013 ); Lysmata cf. lipkei Okuno & Fiedler, 2010 , described from Japan ( Okuno & Fiedler, 2010 ) and likely representing a second nonindigenous species in the region ( Pachelle et al, 2016 ); and L. wurdemanni (Gibbes, 1850) ( Terossi et al, 2018 ).…”

Reproductive output of the ornamental shrimp Lysmata vittata (Stimpson, 1860) (Decapoda: Caridea) in wild populations and under different maturation diets

“…Furthermore, fecundity can also be affected by local environmental conditions (Pandian 2016). Therefore, to better understand the reasons for the low fecundity observed for L. vittata in this study, further studies are needed to investigate the fecundity of this shrimp in other regions, such as the Atlantic Ocean (where this shrimp is considered an invasive species) (Soledade et al 2013;Pachelle et al 2016) and the Pacific Ocean (Ahyong 2010). Notably, fecundity has only been in investigated in a small proportion of species of the Lysmata genus, despite the ecological (Calado 2006;Rosa et al 2014) and economic Rhyne et al 2017) importance of these shrimp.…”

The caridean shrimps of the genus Lysmata Risso, 1816 (Decapoda: Lysmatidae) from Madagascar collected during the Atimo-Vatae expedition: a new species and two new records

“…This is the seventh record of L. lipkei. After being originally described from Japan by Okuno & Fiedler (2010), reported again from Japan by De Grave et al (2012), and subsequently reported from Singapore by Anker & De Grave (2016); this species, based on morphological and genetic data, was recorded from the south-western Atlantic Ocean, Brazil, and classified as alien there by Alves et al (2018) as well two other records from Brazil (Pachelle et al 2016(Pachelle et al , 2020. The present report on L. lipkei from Madagascar significantly extends its known Indo-West Pacific range to the south-west Indian Ocean.…”
