“…The present material differs in only two characters from other records of S. mamillata (see e.g. Hayward and McKinney 2002;Reverter-Gil et al 2015): the species typically presents a peristome developed as a thin rim, most pronounced on each side of sinus. In our material the peristome is absent, but it seems to be broken, perhaps eroded (Figure 3(f)).…”

Although the bryozoological fauna of Galicia (NW Spain) is probably the best known of the whole Iberian Peninsula, and perhaps one of the better known in Europe, new studies continue to provide new knowledge. A new species, Schizotheca galaica sp. nov., is described. Eleven species are newly recorded in Galicia: Aetea longicollis, Parellisina curvirostris, Copidozoum planum, Glabrilaria corbula, Haplopoma sciaphilum, Schizomavella (Schizomavella) mamillata, Fenestrulina asturiasensis, Fenestrulina barrosoi, Buffonellaria muriella, Schizotheca divisa and Dentiporella saldanhai; two of them (B. muriella and S. divisa) are also reported for the first time in Iberian waters; four others (Antarctothoa galaica, F. asturiasensis, F. barrosoi and D. saldanhai) are reported for the first time since their original descriptions, and SEM images of A. longicollis and F. asturiasensis are provided for the first time. Moreover, the range of geographical distribution of some species is expanded: the record of S. divisa is the southernmost to date, while the records of S. mamillata, F. barrosoi and D. saldanhai are the most northerly to date. The presence of other four species in Galician waters is confirmed and we document the permanence and range extension of two species recently introduced into our waters (Tricellaria inopinata and A. galaica).

“…The species attribution of this northern material, however, was not clearly defined and the opinion of Bishop (1994) that it may belong to C. balzaci despite some morphological variations predominated afterwards. Examination of material or SEM photos corresponding to records of C. balzaci in the NE Atlantic (Bishop 1994;Reverter et al 1995;Reverter & Fernández 1996;Hayward & Ryland 1998;De Blauwe 2006, 2009Souto et al 2010) showed that these specimens presented all discriminant characters of C. gautieri Harmelin, n. sp. In the Mediterranean, the record of Collarina punctata at Marseille by Gautier (1962) was based on a few colonies encrusting shells and tests of echinoids in the 50 m depth zone, a habitat typical of C. gautieri Harmelin, n.…”

Unexpected diversity of the genus Collarina Jullien, 1886 (Bryozoa, Cheilostomatida) in the NE Atlantic-Mediterranean region: new species and reappraisal of C. balzaci (Audouin, 1826) and C. fayalensis Harmelin, 1978

The genus Collarina Jullien, 1886 (Cribrilinidae Hincks, 1879) has until now been known from the Atlantic-Mediterranean region as just two species, C. balzaci (Audouin, 1826), synonym of Collarina cribrosa Jullien, 1886, type species of the genus, considered to be widely distributed from the northern British Isles to the SE Mediterranean, and C. fayalensis Harmelin, 1978 from the Macaronesian Isles. Abundant material collected in the Mediterranean and the NE Atlantic, coupled with examination of museum specimens, allowed better definition of the species-specific morphological features in this genus and some generic traits (ooecium formation, avicularia with nested cystids). Besides the redescription of C. balzaci and C. fayalensis, this study led to the description of four new species: C. denticulata Harmelin, n. sp., recorded only in the Mediterranean, C. gautieri Harmelin, n. sp., present in both the NE Atlantic and the Mediterranean, C. macaronensis Harmelin, n. sp., from Madeira, Azores and

“…The absence of Schizomavella species is all the more surprising in that this genus is one of the most species-rich in the Mediterranean (Rosso, 2003;Reverter-Gil et al, 2016) and that several species [e.g. S. mamillata (Hincks, 1880), S. cornuta (Heller, 1867)] are major components of the landscape of coastal rocky bottoms in the western Mediterranean.…”

High xenodiversity versus low native diversity in the south-eastern Mediterranean: bryozoans from the coastal zone of Lebanon

Because of its location in the warmest corner of the Mediterranean, its proximity to the northern entrance of the Suez Canal, i.e. the gateway for massive exotic biota introduction into the Mediterranean, the occurrence of high shipping activity and strong human pressure, the Lebanese coastal zone is an area that is exceptionally well-suited for investigating the effects of these extreme conditions on Mediterranean biodiversity. Bryozoans, which are among the main components of sessile communities, reflect dramatically the impact of these particular conditions. Their assemblages, sampled by diving along the whole coast of Lebanon during a pluriannual programme, mainly between 1999 and 2003, consist of 93 species (12 Cyclostomata, 2 Ctenostomata, 79 Cheilostomata). The native part of this bryozoan fauna exhibits low diversity, with an unexpected absence of many taxa, from family to species level, which are very common in the rest of the Mediterranean. It is also characterized by a high proportion of endemic species, in contrast with the general eastward trend of decreasing endemicity observed in the Mediterranean, and by the strong presence of 'southern' thermophilic species. With 27 non-indigenous species, xenodiversity is exceptionally high, particularly in the cheilostome pool (26 species), but was likely undersampled. Moreover, one may assume that new non-indigenous bryozoans (NIB) are now established along the Levantine coasts. This trend is expected to increase in the near future with the intensification of surface water warming and boost of shipping activity and propagule flux generated by the expansion of the Suez Canal.
