A precautionary tale when describing species in a world of invaders: morphology, coloration and genetics demonstrate that Lysmata rauli is not a new species endemic to Brazil but a junior synonym of the Indo-Pacific L. vittata

Morphological remarks on the peppermint shrimp Lysmata ankeri (Decapoda, Hippolytidae): implications for species identification of the L. wurdemanni complex

“…Burukovsky, 2000;Rhyne and Anker, 2007;Okuno and Fiedler, 2010). For example, Laubenheimer and Rhyne (2010) described a new species of peppermint shrimp, Lysmata rauli, and in a subsequent study, Soledade et al (2013) showed, based on morphological characters, color pattern and genetics, that L. rauli is not a new species endemic to Brazil but rather is a junior synonym of Lysmata vittata (Stimpson, 1860) from the Indo-Pacific. This study contributes to the expansion of the variation limits of the number of teeth on the dorsal margin of the rostrum and the number of spines on the flexor margin of the dactyli in L. ankeri.…”

First record of exotic Lysmatid shrimp Lysmata vittata (Stimpson, 1860) (Decapoda: Caridea: Lysmatidae) from the Egyptian Mediterranean coast

“…The genus Lysmata Risso, 1816, a member of the family Lysmatidae Dana, 1852, contains more than 48 described species (e.g., Anker et al, 2009;De Grave & Fransen, 2011;De Grave et al, 2014;WoRMS, http:// www.marinespecies.org/aphia.php?p=taxlist, March 30, 2018), including the species previously placed in Hippolysmata Stimpson, 1860. There is a rather confusing synonymy of several taxa, based on variations of some morphological characteristics (Chace, 1997;d' Udekem d'Acoz, 2000;Soledade et al, 2013;Alves et al, 2015), as well as portraying new species (e.g. Zhibin & Xinzheng, 2016;Prakash & Baeza, 2017).…”

New records of the striped cleaner shrimp Lysmata grabhami (Gordon, 1935) from Brazil, Southwestern Atlantic

“…Most of them dwell in shallow tropical waters and are associated with seagrass or reef environments (Bauer, 2004). Forty-two species belong to the genus Lysmata Risso, 1816 (De Grave and Fransen, 2011), 14 of which are known to occur in the Atlantic Ocean (Rhyne and Lin, 2006;Soledade et al, 2013). The genus contains several so called cleaner shrimp species that are highly valued by the marine ornamental trade, due to their striking coloration, little aggressiveness and interesting cleaning behavior (Calado et al, 2003).…”
