New Records of Species of Pontella Dana, 1849 and Ivellopsis Claus, 1893 and a Re-Examination of These Genera (Copepoda, Calanoida) Around Some Small Islands in Indonesian Waters
Five new Indonesian records of species of the genus Pontella Dana, 1849 and one species of the genus Ivellopsis Claus, 1893, i.e., Pontella diagonalis C. B. Wilson, 1950, Pontella forficula A. Scott, 1909, Pontella sewelli Heinrich, 1987, Pontella spinipes Giesbrecht, 1889, Pontella surrecta C. B. Wilson, 1950, and Ivellopsis elephas (Brady, 1883) are reported herein. All species are redescribed and figured from specimens collected from eight small islands and off Bojonegara in Indonesian waters. Descriptions of the males of P. diagonalis, P. forficula, and P. spinipes have been published previously by Mulyadi (2000). Subsequently, a misidentification, which resulted in wrong species identity, was discovered in P. forficula: A. Scott's P. forficula, which was only described from male specimens, is recognized to represent the male of I. elephas.Descriptions, measurements, and figures of those species are given, along with a review of their distribution over Indo-Pacific waters, and together with taxonomic remarks and restricted synonymies.
