| Summary: | Identifi cation of larval mesoplankton is essential to the study of the supply-side ecology of marine benthic or sessile organisms, such as barnacles. Combined morphological and molecular identifi cations of wild-caught
barnacle cyprids from Matang Mangrove Forest Reserve(MMFR), Malaysia were studied based on mitochondrial 12S-rRNA gene sequences of the unidentifi ed larvae and identifi ed adults. Six species of barnacle adults and cyprids had matched DNA sequences. These included Fistulobalanus pattellaris, Fistulobalanus sp., Amphibalanus reticulatus,
Amphibalanus variegatus, Amphibalanus amphitrite, and Euraphia withersi. Morphological characters of the identified cyprids were described, and used to develop a morphology-based classifi cation tree. Carapace sculpturing pattern on the cyprids was the most important morphological discriminator. Preliminary analysis of the diversity of barnacle cyprids in MMFR showed that the dominant species could be morphologically classifi ed with high accuracy. |
