Résumé. – Premiers signalements de deux Sparidae, Diplodus
omanensis et Pagellus affinis (Perciformes: Sparidae) en provenan-
ce de l’ouest du Pakistan.
un Diplodus omanensis Bauchot & Bianchi, 1984 et un Pagel-
lus affinis Boulenger, 1888, ont été recueillis sur le marché de
karachi, probablement en provenance de la côte ouest du Pakistan,
en mer d’Arabie. Ces spécimens représentent les premiers signale-
ments de ces deux espèces de sparidés dans les eaux pakistanaises.
Key words. – Sparidae - Diplodus omanensis - Pagellus affinis -
Pakistan - Arabian Sea - new records.
Pakistani fish fauna has been object of few general studies (Day,
1875; Bianchi, 1985; Hoda, 1988). Concerning sparids, our knowl-
edge of the distributional limits of most fishes of the Western Indian
Ocean is still poor. Hoda (1988) reported 10 species from Pakistan
waters: Acanthopagrus berda, A. bifasciatus, A. latus, Argyrops
spinifer, Cheimerius nufar, Crenidens crenidens, Diplodus sargus
kotschyi, Rhabdosargus sarba, R. haffara, and Sparidentex hasta.
recently a joint research was carried out by Pakistani and Japa-
nese fish researchers in the two landing ports of Karachi City and
keti Bandar (an estuary of the indus river of Sindh), and river
Basin, northwestern karachi, Pakistan from 19 may to 1 June 2012.
we secured a specimen of Oman Porgy, Diplodus omanensis Bau-
chot & Bianchi, 1984 and a specimen of Arabian Pandora, Pagellus
affinis Boulenger, 1888. The former is known only from southern
Oman and the latter is also known only from the “Gulf” to the Gulf
of Aden including southern Oman and northern coast of Somalia Figure 1. - A: Diplodus omanensis, 310 mm SL; B: Pagellus affinis, 183 mm
