Review of the harvestfishes, genus Peprilus (Perciformes: Stromateidae), <br />of the Atlantic coast of South America

Abstract

Currently, seven valid species are recognized in the genus Peprilus. Found from United States to Argentina, Peprilus paru has a complex nomenclatural history, with seven junior synonyms, three from North America and four from South America. As there has been no recent research, it remains unclear whether species representatives in the north-south axis represent different populations of a single species or distinct species. By comparison of type specimens as well as a comprehensive collection of non-type specimens, this paper aims to clarify the taxonomic status of the nominal species listed as junior synonyms of Peprilus paru in the Atlantic side of South America. Based on morphological data and DNA barcoding, Peprilus crenulatus Cuvier, 1829 and P. xanthurus (Quoy & Gaimard, 1825) are resurrected, while Rhombus argentipinnis Cuvier, 1833 and Rhombus orbicularis Guichenot, 1866, are considered to be junior synonyms of P. crenulatus.

Fish species caught by shrimp trawlers off the coast of Sergipe, in north-eastern Brazil, and their length–weight relations

“…These values may also be influenced by differences among seasons (Pauly 2010), localities, and feeding habits (Wootton 1998). This is the first time that an LWR is presented for G. cavifrons, and P. crenulatus under their revised scientific names (Tavera et al 2011, Marceniuk et al 2016.…”

“…Length-weight relations (LWRs) for all fish species caught by shrimp trawlers off the coast of Sergipe, Brazil (with n ≥ 20) n = number of individuals, TL = total length observed, TL max = total length reported in FishBase, L m = length at first maturity reported in FishBase; a and b = parameters of the LWR, SE = standard error, r 2 = coefficient of determination; only species with more than 20 specimens examined and the maximum observed length representing more than 70% of the maximum size reported in FishBase (Froese and Pauly 2018) or significantly higher than L m are presented; 1 no LWR found for Brazil, 2 LWR not found for NE Brazil; 3 new species name according to Tavera et al (2011) and Marceniuk et al (2016), 4 TL max obtained in this study higher than currently reported in FishBase, 5 b statistically different from 3.…”

Observations on the ontogeny of butterfish <i>Stromateus stellatus</i> larvae (Pisces: Stromateidae) off central Chile

“…The butterfish family Stromateidae contains 3 genera, Pampus, Peprilus and Stromateus, with about 17 species (Nelson 2006, Marceniuk et al 2016. This clade is supported by several synapomorphies, such as pterosphenoid expanding anteriorly, slightly separating from lateral ethmoid by a small cartilage; no teeth on palatine; anterior ends of bilateral fifth ceratobranchials articulating with one another via cartilaginous basibranchial; a single pair of uroneurals; proximal radials of first and second pterygiophores of the anal fin greatly elongated posterodorsally, flanking second to third, or fourth hemal spines; ventral arm of coracoid articulates with cleithrum above its ventral end; single dorsal fin; and pelvic fins always absent or rarely present only in young (Doiuchi et al 2004).…”
