Further record of the shallow water mysid Heteromysis proxima W. M. Tattersall, 1922 (Mysida) from the Malacca Strait

抄録

Heteromysis proxima W. M. Tattersall, 1922 (Mysida) was first reported from the Gulf of Manaar, off the south-eastern coast of India. A recent sledge net survey conducted on the north-western coast of Malaysia yielded several specimens of this little-known mysid from a sandy beach located in the mouth area of Merbok River, facing the Malacca Strait. Although the Malaysian specimens have a comparatively smaller body size than those recorded from India, the morphological features of these specimens essentially agree with the typical ones. This paper provides further information on the morphological characteristics of H. proxima on the basis of newly obtained specimens and extends its geographical range to the Malacca Strait.
