| Abstract |
Based on adult morphological characters, the more than 300 species of Alpheus were divided into seven informal species groups, but some groups are not supported by molecular data. The aim here was to describe the zoea I of Alpheus bouvieri, and to do a review of the larval descriptions available in the literature, analysing whether the morphological groups proposed for adults are supported by larval data. The new larvae were obtained from females sampled in Pernambuco and Rio Grande do Norte, Brazil. Alpheus bouvieri zoea I shares a combination of characters with most larvae in the genus, but with some diagnostic characteristics: endopod of the maxillule and maxilla with 3 and 4 setae, respectively, the base of the first maxilliped with 9 setae, endopod of the second and third maxilliped with 5 and 6 segments, respectively. In our review, 23 species were analysed from five groups: edwardsi (thirteen), sulcatus (four), brevirostris (three), macrocheles (two), and obesomanus (one) group; the zoea I of species from diadema and crinitus groups are unknown. Based on this review, many issues regarding mistakes in the zoea I description of Alpheus are pointed out, and the hypothesis that the morphological groups proposed for adults are supported by larval data has been rejected. |
