“…The valid name for this species has been debated although there is a consensus among recent authors on using the name radiata for the Red Sea/Mediterranean species (WADA & T MKIN, 2008). The type locality was nevertheless stated, with a question mark, as Caribbean and the name is also used for the very similar, if not identical, Western Atlantic species otherwise known as P. imbricata (Röding, 1798).…”

One hundred years after Pinctada: an update on alien Mollusca in Tunisia

et al. 2011

The occurrences of non-indigenous marine molluscs in Tunisia are reviewed, based both on a literature survey and on original material. Species are accepted as established if there are two independent reports, either geographically separate or at least one month apart in time. On these grounds, fourteen species are accepted (twelve alien and two expanding their range from elsewhere in the Mediterranean), three aliens need confirmation but are likely to meet the standards for acceptance in the near future, and five records are rebutted or questioned. Two more species may be considered as cryptogenic, the reports are reliable but there is no clear indication that they are not indigenous. Two of the alien species are reported for the first time in Tunisian waters: the nudibranch Polycerella emertoni qualifies as established, and the bivalve Anadara transversa is tentatively identified from a live juvenile specimen, which awaits further confirmation.The occurrence of aliens in Tunisia is balanced between presumably Lessepsian species of tropical Indo-Pacific origin, and species from other sources including species from the tropical Atlantic introduced through shipping. Nevertheless there is a prevalence of Lessepsian species towards the Gulf of Gabès in the south, while the shipping activity in Tunis harbour may be the main pathway of introduction in the north.

“…The Akoya pearl oyster has a broad Indo-Pacific distribution and is also found in the Mediterranean Sea and Caribbean (Wada & Temkin 2008). Within this range it supports large cultured pearl industries in China and Japan (Southgate et al 2008) that contribute around 22% of global cultured pearl production, with a value of approximately US$135 million per annum or 21% of the global industry value (Southgate 2007).…”

“…The general outline resembles Pinctada radiata (Leach, 1814) from the Red Sea and Mediterranean and the Indo-Pacific P. fucata. Overall similarities have led some authors to gather P. imbricata and several several Indo-Pacific species in a so called large species complex named Pinctada fucata /martensii /radiata/ imbricata complex by WADA and TËMKIN (2008). Alternatively, some authors consider them a single species with a cosmopolitan range (e.g.…”

In the present study, we compared the internal and external anatomy of pearl oyster (Pinctada imbricata Röding, 1798) from some South American localities, including Venezuela and several regions of Brazil. The anatomical data shows non-geographical variations characterized by variable outline in adults, different degrees of posterior auricle shell development and mantle papillae ranging from normal to digitiform. The geographical variations can be divided into two major groups: the Venezuelan group presents a more folded mantle; pallial muscle grouped in anterior and median-posterior sets; poorly-developed perpendicular mantle groove; inner lamella not extended into the anterior mantle. Brazilian group specimens present a smoother mantle, with less clear separation between anterior and posterior mantle muscle groups; externally-developed perpendicular groove; inner lamella extension developed in anterior mantle. These differences may represent ecophenotypes or differences among isolated South American populations, which may be elucidated by subsequent phylogeographic studies.Keywords: Bivalvia; Pteriomorphia; pearl oyster; anatomy; intraspecific variation DIFERENÇAS ANATÔMICAS ENTRE ESPÉCIMES DE Pinctada imbricata RÖDING, 1798 DE DIFERENTES LOCALIDADES DA AMÉRICA DO SUL RESUMONo presente estudo comparou-se a anatomia da ostra perlífera (Pinctada imbricata Röding, 1798) de algumas localidades da América do Sul, incluindo a Venezuela e várias regiões do Brasil. Foram encontradas variações não geográficas e geográficas. As variações não geográficas foram caracterizadas por adultos com contorno bem variável, diferentes graus de desenvolvimento da aurícula posterior e papilas da lamela interna do manto variando de normal a digitiformes. Variações geográficas podem ser divididas em dois grandes grupos: o grupo venezuelano apresentou um manto mais pregueado; musculatura palial agrupada em dois conjuntos de feixes -um anterior e outro mediano-posterior; sulco perpendicular do manto pouco desenvolvido. Espécimes dos grupos brasileiros apresentaram um manto menos pregueado, com separação menos nítida entre os feixes musculares paliais anterior e posterior do manto; sulco perpendicular do manto bem desenvolvido; lamela interna do manto se estendendo externamente na região do manto anterior. Essas diferenças podem ser ecofenótipos ou diferenças entre as populações com certo grau de isolamento da América do Sul, que podem ser elucidados por estudos filogeográficos subsequentes.
