On the occurrence of the tropical caprellid Paracaprella pusilla Mayer, 1890 (Crustacea: Amphipoda) in Europe

“…The morphological characteristics used to define P. pusilla were: (1) the large anterolateral projection of pereonite 2; (2) the small dorsal tubercle on pereonite 2; (3) the proximal knob on the basis of gnathopod 2; and (4) the lateral pleura in pereonites 3 and 4, more specially developed in pereonite 3 (shown in plate 2, figures 36 and 37 from Mayer, 1903). The specimens collected in Cadiz were found to display these features.…”

“…Paracaprella pusilla, originally described by Mayer (1890) from Brazil (type locality: Rio de Janeiro), is one of the most abundant caprellid species found along the Caribbean coast of Venezuela and Colombia (Díaz et al, 2005;Guerra-García, 2006). The species' natural distribution is along the Atlantic coasts of Central and South America (Mayer, 1903), with most of the records from the coasts in the Gulf of Mexico and the Caribbean (Fig. 1).…”

Description of two species of Caprella (Crustacea: Amphipoda: Caprellidae) from the North Pacific; C. californica Stimpson, 1857 and C. scauroides Mayer, 1903, with a new appraisal of species ranking for C. scauroides

“…Mayer (1890Mayer ( , 1903 recognized 6 ''formae'' (=varieties), that is, Caprella scaura f. californica Stimpson from California, C. scaura f. cornuta Mayer, 1890 from Brazil, C. scaura f. diceros Mayer, 1890 from Japan, C. scaura f. scauroides Mayer, 1903 from Hong Kong, China and Japan, C. scaura f. spinirostris Mayer, 1903 from Chile, and C. scaura f. typica Mayer, 1890 from Brazil, under Caprella scaura Templeton, 1836 originally reported from Mauritius in the south Indian Ocean. According to recent rules of nomenclature, these ''formae'' are now treated as subspecies, and the nominal subspecies of C. scaura from Mauritius, the type locality, should be regarded as Caprella scaura scaura Templeton (see Krapp et al 2006).…”

Notes on the occurrence of Orthoprotella spinigera Mori, 1996 (Crustacea: Amphipoda: Caprellidae) from Okinawa Island, Japan

“…These specimens appeared similar to Metaprotella sandalensis Mayer, 1898, which is widely distributed in shallow waters of the tropical Indo-West Pacific coasts (see Mayer 1898, 1903, McCain & Steinberg 1970, Müller 1990, Laubitz 1991, Lim & Takeuchi 2012. However, closer inspection of these specimens revealed that they are Orthoprotella spinigera Mori, 1996, previously known only from Tomioka, Amakusa Islands, on the west coast of Kyushu.…”
