Thrissina katana sp. nov., a new thryssa from the western Pacific Ocean, and redescription of Thrissina hamiltonii (Gray, 1835) (Teleostei: Clupeiformes: Engraulidae)

A New Species of Thrissina from the Andaman Sea and Re-assessment of the Taxonomic Status of Thrissina cuvierii (Swainson, 1839) and Thrissina malabarica (Bloch, 1795) (Teleostei: Clupeiformes: Engraulidae: Coiliinae)

“…The only species of the genus reported from the Indian coast with a moderate maxilla (just reaching or extending slightly beyond the opercular margin) and elongate body are Thrissina gautamiensis (Babu Rao, 1971), Thrissina hamiltonii (Gray, 1835), Thrissina kammalensoides (Wongratana, 1983), Thrissina polybranchialis (Wongratana, 1983), Thrissina purava (Hamilton, 1822), and Thrissina spinidens (Jordan and Seale, 1925). Moreover, the illustration given in Bloch's ( 1795 anal-fin rays) is also thought to be a different species (Wongratana, 1983;Whitehead et al, 1988;Wongratana et al, 1999;Hata et al, , 2022this study). For these reasons, C. malabaricus described by Bloch (1795) appeared to be either T. hamiltonii (redescribed by Hata et al, 2022) or T. gautamiensis (redescribed by Whitehead et al, 1988).…”

For these reasons, C. malabaricus described by Bloch (1795) appeared to be either T. hamiltonii (redescribed by Hata et al, 2022) or T. gautamiensis (redescribed by Whitehead et al, 1988). In the original description of the former, Bloch (1795) also noted, "Der Mund ift mit zarten Zahnen verfehen [the mouth has fine teeth]".…”

“…Because the teeth on both jaws of T. gautamiensis are enlarged (cf. teeth on both jaws of T. hamiltonii-small and conical; Whitehead et al, 1988;Hata et al, 2022), C. malabaricus Bloch ( 1795) is now considered to be a senior synonym of T. hamiltonii. Because the type specimens of C. malabaricus are no longer extant (above), the neotype of Thrissa hamiltonii Gray, 1835(BMNH 1979 Valenciennes's (1848) description of an engraulid species collected from Bombay (currently Mumbai), India as "Engraulis malabaricus," included meristics and morphological features, plus an informative illustration (pl.…”

“…Among them, an Indian Ocean species with a distinctly deep body has been treated as Thrissina malabarica (Bloch, 1795;e.g., Nair, 1953;Misra, 1976;Whitehead et al, 1988;Psomadakis et al, 2015). However, examination of the original description of T. malabarica revealed that name to be a senior synonym of Thrissina hamiltonii (Gray, 1835), recently re-described by Hata et al (2022). Consequently, the applicable name for the species formerly regarded as T. malabarica is Thrissina cuvierii (Swainson, 1839), previously considered to have been a junior synonym of T. malabarica (Whitehead et al, 1988).…”

Redescription of Anchoviella cayennensis (Puyo, 1945) (Clupeiformes: Engraulidae), with the synonymization of Anchoviella sanfranciscana Barbosa, Gomes da Silva, da Rocha Araújo & Carvalho, 2017 and remarks on Anchoviella perfasciata (Poey, 1860)

“…The Engraulidae includes 17 genera and c . 170 species of the typically small‐ to medium‐sized coastal and schooling fishes commonly known as anchovies (Hata et al ., 2022; Loeb et al ., 2018; Whitehead et al ., 1988). Anchovies are relevant to artisanal and industrial fisheries on a global scale ( e.g ., Birge et al ., 2021), with recent catches of just a single species, Engraulis ringens (eastern Pacific of South America), reaching up to 12 million tonnes (FAO, 2020).…”
