“…A detailed examination of osteological and myological features was not carried out on Simipercis; however it agrees well with the familial diagnosis and description of Rosa and Rosa, 1998 and with additional features of the family defi ned by Imamura and Matsuura, 2003 that were examined (eg. unique crest on the hyomandibular present, posterior margin of opercular bone moderately concave, six branchiostegal rays, lowermost ray of pectoral fi n branched, 15 branched caudal-fi n rays).…”

“…The Pinguipedidae currently contains fi ve genera: the monotypic Kochichthys Kamohara, 1961 from Japan and Taiwan, Pinguipes Cuvier, 1829 with one species from each of the south-eastern Pacifi c and south-western Atlantic, the monotypic Prolatilus Gill, 1865 from the south-eastern Pacifi c, Pseudopercis Miranda-Ribeiro, 1903 with two species from the south-eastern Atlantic, and Parapercis Bleeker, 1863 with about 54 recognised species, including 51 from the Indo-west Pacifi c and single representatives in the south-eastern Pacifi c, south-eastern Atlantic and north-eastern Atlantic (Rosa and Rosa, 1998;Randall and McCosker, 2002;Imamura and Matsuura, 2003;Randall, 2003;Randall and Yamakawa, 2006; this study).…”

Simipercis trispinosa is described as a new genus and species of pinguipedid fi sh from 93 specimens collected mostly by demersal trawl from the continental shelf of eastern Australia between Swain Reefs, Queensland and Broken Bay, New South Wales in depths from 51 to 170 m. The new genus is most closely related to Parapercis Bleeker, 1863, but is unique among pinguipedid fi shes in having a combination of vomer and palatines edentate, dorsal spines 3, no distinct exposed, pointed opercular spine, preopercle and subopercle entire, ten abdominal and 20-21 caudal vertebrae, low naked fl eshy nuchal crest, interorbital and suborbital with large ctenoid scales extending forward to near anterior margin of eye, and head and body moderately compressed.

“…T wo major arrangements have been shown for the trachinoid family Pinguipedidae: one includes the monotypic Cheimarrichthys von Haast, 1874, in the family (e.g., McDowall, 1973McDowall, , 2000Randall, 1984;Paulin et al, 1989;Eschmeyer, 1998); and another excludes the genus from the Pinguipedidae and places Cheimarrichthys in its own family, Cheimarrichthyidae (e.g., Pietsch, 1989;Nelson, 1994;Rosa and Rosa, 1997). However, no detailed revisionary studies have been carried out on the relationships of the Pinguipedidae and Cheimarrichthys.…”

The phylogenetic relationships of the family Pinguipedidae plus the genus Cheimarrichthys von Haast, 1874, were studied to redefine the family. Based on a phylogenetic analysis using derived characters belonging to 21 transformation series, accepting the monophyly of Pinguipedidae plus Cheimarrichthys provisionally for the operational procedure of the analysis, it was hypothesized that Cheimarrichthys is not closely related to Parapercis Bleeker, 1863, although these genera had been considered as having a close affinity. Although the Pinguipedidae and Cheimarrichthys share nine derived characters, it was determined that these characters are also found in other trachinoid families. In addition, several families, such as the Leptoscopidae, Uranoscopidae, and Trichodontidae, have many more derived characters in common with Cheimarrichthys than the pinguipedids have with that genus. The conclusion drawn here is that it is not parsimonious to recognize the monophyly of the Pinguipedidae and Cheimarrichthys based on these nine derived characters, and that these characters are not compelling enough to link these groups. The redefined Pinguipedidae is proposed to include the following five genera: Parapercis, Prolatilus Gill, 1865, Pinguipes Cuvier, 1829, Pseudopercis de Miranda-Ribeiro, 1903, and Kochichthys Kamohara, 1960. Cheimarrichthys, excluded from the Pinguipedidae, is put into its own family, Cheimarrichthyidae.

“…Along the Pacific coasts of South America, two species coexist: Pacific sandperch, Prolatilus jugularis (Valenciennes, 1833) and Chilean sandperch Pinguipes chilensis Valenciennes, 1833 (Rosa and Rosa 1997). P. jugularis is distributed from Huacho, Peru (11°11′S) to Chiloé, Chile (43°43′S), while P. chilensis is distributed from Tumbes, Peru (3°S), to the Magellan Strait (54°S).…”

Summary:Two species of sandperch (Pinguipedidae: Perciformes), Prolatilus jugularis and Pinguipes chilensis, inhabit the coastal waters of the South Pacific. Both species have pelagic larvae with similar morphology, but their diet preferences are unknown. Diet composition, feeding success, trophic niche breadth and dietary overlap were described during larval stages for both species. In the austral spring, larval P. jugularis (3.83-10.80 mm standard length [SL]) and P. chilensis (3.49-7.71 mm SL) during their first month of life had a high feeding incidence (>70%) and fed mostly on copepod nauplii (>80% IRI), Rhincalanus nasutus metanauplii and Paracalanus indicus copepodites. The number of prey ingested was low (mean: 4-5 prey per gut) and independent of larval size; total prey volume and maximum prey width increased as larvae grew. Mouth opening and ingested prey were greater in larval P. jugularis than in P. chilensis, leading to significant differences in prey composition among larval species, in terms of prey number and volume. Pearre's trophic niche breadth was narrow for both species (0.159±0.07 for P. jugularis; 0.156±0.03 for P. chilensis) and independent of larval size. Dietary overlap was high inter-and intra-species in larvae with a mouth gape <900 μm. These results suggest the relative importance of both larval species as primary consumers of the pelagic web in nearshore environments of rocky temperate areas.Keywords: Prolatilus jugularis; Pinguipes chilensis; sandperch, feeding; resource partitioning; Chile.Hábitos alimentarios y superposición de la dieta durante el desarrollo larval de dos blanquillos (Pisces: Pinguipedidae) Resumen: Existen dos especies de blanquillo (Pinguipedidae: Perciformes), Prolatilus jugularis y Pinguipes chilensis que habitan las aguas costeras del Pacífico Sur. Ambas especies tienen larvas pelágicas con morfología similar, pero se desconocen sus preferencias de la dieta. Se describen la composición de la dieta, amplitud del nicho trófico y superposición trófica durante los estados larvales de ambas especies. En primavera, las larvas de P. jugularis (3.83-10.80 mm LE) y P. chilensis (3.49-7.71 mm LE) durante su primer mes de vida tienen alta incidencia alimentaria (>70%) y se alimentan principalmente de nauplii de copépodos (>80%IRI), metanauplii de Rhincalanus nasutus y copepoditos de Paracalanus indicus. El número de presas ingeridas fue bajo (media: 4-5 presas por estómago) e independiente del tamaño larval; el volumen total de presas y el ancho máximo de las presas se incrementó a medida que crecían las larvas de ambas especies. El largo de la mandíbula y el tamaño de las presas fue más grande en larvas de P. jugularis comparado con las de P. chilensis. Esto generó diferencias significativas en la composición de las presas entre especies, en términos de número y volumen de las presas ingeridas. La amplitud del nicho trófico de Pearre fue bajo para ambas especies (0.159±0.07 para P. jugularis; 0.156±0.03 para P. chilensis) e independiente del tamaño larval. La superpos...
