Hm. Banford et Bb. Collette, HYPORHAMPHUS-MEEKI, A NEW SPECIES OF HALFBEAK (TELEOSTEI, HEMIRAMPHIDAE) FROM THE ATLANTIC AND GULF COASTS OF THE UNITED-STATES, Proceedings of the Biological Society of Washington, 106(2), 1993, pp. 369-384
Hyporhamphus meeki is described from the Atlantic and Gulf of Mexico c
oasts of the United States. It has been confused previously with H. un
ifasciatus (Ranzani) which occurs from southern Florida, Bermuda, the
West Indies, and Mexico south to southern Brazil. Hyporhamphus meeki h
as more gill rakers, usually 33-39 on the first gill arch and 26-29 on
the second arch compared to 28-32 on the first arch and 19-25 on the
second arch in H. unifascialus. Pectoral-fin rays are usually 11 or 12
vs. 10 or 11 in H. unifasciatus. The ratio of preorbital length to or
bit diameter is usually greater than 0.70 in H. meeki, less than 0.70
in H. unifasciatus.
