Inproceedings Reference The meiofauna paradox unresolved: Cryptic speciation in Gyratrix hermaphroditus (Kalyptorhynchia, Platyhelminthes).
Inproceedings Reference There’s more than meets the eye: population structure in the Ceratitis “FAR complex”.
Analyses of mitochondrial and nuclear DNA sequences hitherto failed to resolve the three morphospecies of the so-called Ceratitis “FAR complex” (C. fasciventris, C. anonae, C. rosa). Therefore, we developed a set of microsatellite markers for a first population genetic survey of this species complex. Specimens of C. fasciventris, C. anonae, and C. rosa (27 populations, n=621) collected across their respective distribution ranges were genotyped at 16 polymorphic microsats. Genetic distance analyses distinguished at least five bootstrap supported population groups, each including samples from one of the three morphospecies. The Bayesian assignments implemented in STRUCTURE show that (1) C. rosa is represented by at least two clusters of individuals (R1, R2) that can occur in sympatry/parapatry, but that may have different developmental thresholds, (2) C. fasciventris is represented by at least two, geographically separated, clusters (F1, F2), and (3) C. anonae is genetically more homogeneous and doesn’t show a clear intraspecific structuring (cluster A). The differentiation of the C. rosa and C. fasciventris clusters is supported by morphological differences in the male secondary sexual characters. Genetic divergences between the C. rosa clusters and between the C. fasciventris clusters are comparable to the interspecific divergences among C. fasciventris, C. anonae, and C. rosa. Higher genetic distances were observed between the morphologically similar C. rosa and C. fasciventris, while C. anonae appears as closely related to both F1 and R2. The microsats used in this study thus unmasked a complex, and partly cryptic, population genetic structure within the FAR morphospecies. Keywords: Tephritidae, population genetics, microsats

Article Reference The genus Pradoxa Fernandes & Rolán, 1993 (Gastropoda: Muricidae) in SãoTomé, Príncipe and Annobón.
The genus Pradoxa is revised and all the species are described, compared and illustrated. Two new species are described from São Tomé, Pradoxa gorii spec. nov. and P. urdambideli spec. nov. The radula is illustrated for P. confirmata (Fernandes & Rolán, 1990), P. thomensis (Fernandes & Rolán, 1990) and P. gorii spec. nov. The subfamilial classification is discussed and a comparative table is added in the appendix.
Article Reference Description of Muricopsis (Muricopsis) gorii (Gastropoda: Muricidae: Muricopsinae) from southern São Tomé.
A new species of Muricopsis is described from Sete Pedras Island, São Tomé. It is compared with Muricopsis matildeae Rolán & Fernandes, 1991.
Article Reference Description of a new Murexsul (Gastropoda: Muricidae: Muricopsinae) from the Sultanate of Oman.
A new species, Murexsul khareefae, is described from the southern province of Dhofar, Oman. Key words: Sultanate of Oman, Indian Ocean, Gulf of Oman, Muricidae, Murexsul, new species.
Article Reference Description of a new species of Siratus (Gastropoda: Muricidae) from Guadeloupe, Lesser Antilles.
Siratus michelae is described from six specimens dredged in about 70 m depth off Martinique, French Antilles. It is compared with S. cailleti (Petit, 1856) and S. kugleri (Clench & Pérez Farfante, 1945), both also occurring in the same area, but at greater depth.
Article Reference New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.
Fourteen species of Muricidae referable to the (sub)genera Promurex Ponder & Vokes, 1988, Pygmaepterys Vokes, 1978, Murexsul Iredale, 1915, Pazinotus Vokes, 1970, Prototyphis Ponder, 1972, Ponderia Houart, 1986, Gemixystus Iredale, 1929, Leptotrophon Houart, 1995 and Scabrotrophon McLean, 1996 are reported from New Caledonia, the Solomon Islands and Taiwan, to depths down to 1750 m. Five new species are described: Favartia (Pygmaepterys) lifouensis n. sp. from New Caledonia with range extension to the Solomon Islands, Pazinotus chionodes n. sp. and Gemixystus calcareus n. sp. from New Caledonia, Leptotrophon wareni n. sp. from the Solomon Islands and Favartia (Pygmaepterys) circinata n. sp. from Taiwan.

Article Reference Cenozoic evolution of Muricidae (Mollusca, Neogastropoda) in the Southern Ocean, with the description of a new subfamily
Gastropods are among the most studied group in Antarctica, and taxa with an advanced status of systematic knowledge can be used as a model to study how oceanographic and climatic patterns shaped Recent faunal assemblages. Within the ongoing study of the muricid phylogeny, we have analysed molecular and morphological data from species traditionally ascribed to the muricid subfamily Trophoninae. Particularly, the availability of specimens collected in the Southern Ocean and surrounding basins allowed to demonstrate as the genera Pagodula, Xymenopsis, Xymene and Trophonella, which are traditionally classified in the Trophoninae, actually belong to a distinct lineage, for which the new subfamily Pagodulinae is herein introduced. We propose and discuss a possible framework for the origin and radiation of Antarctic muricids.
