Map showing the distribution of L. acuta in the Indian Ocean. It may be noted that most of the records are from coastel waters.
Nota: According to Fleminger (pers. comm.) the records from the Atlantic are based on misidentification. L. acuta is known at present from both neritic as well as island associated waters in the Pacific Ocean and the Indian Ocean. |

labidocera copepods of the Gulf of California and Baja California. Three 'Labidocera species, not closely related, which mix with both ''L. jollae group'' and ''L. trispinosa group. All have more offshore habitat preferences: two are oceanic, L. acutifrons being broadly tropical, whereas L. detruncata is equatorial; L. acuta is broadly neritic and equatorial. |

Sporadic in the Atlantic.
After Silas & P. Pillai (1969), Giesbrecht (1892) described and illustrated two types of variants as L. acuta from the Indian Ocean, Arabian Sea, Red Sea, Hong Kong and the Philippines. To the 1st type (Giesbrecht: Pl.41, figs.10, 19, 28) may be referred the typical L. acuta described by Dana and Brady. The 2nd type (Giesbrecht: Pl.41, fig.29) obtained from the Arabian Sea and the Red Sea, shows marked differences in the nature of the urosome, especially genital segment, caudal rami and disposition of the caudal setae and the structure of the inner 2nd and 3rd setae, and P5. Giesbrecht did not give a name for this variant. Breemen (1908) has reproduced Giesbrecht's drawings of P5 of the variant and called it: 'L. acuta var.'
