Cochlostoma bicostulatum Gofas 1989
No full textCochlostoma bicostulatum Gofas, 1989 (®gures 31±34) Cochlostoma bicostulatum Gofas, 1989: 45 ±46, ®gure 6±9. Type locality: Seldesuto, near Matienzo (Santander)ÐHOLOTYPE MNHN. PARATYPES MNHN, MNCN, MZB, UPV. Manuscript names in Museum collections: Pomatias bicostulatum Aguiar-Amat`des®ladero de Beyos, Asturias, D. Quatrecasas leg. et det.’ MZB 80.0047. Cochlostoma azpeitianum Ortiz de Zarate in coll. Altimira (®de Raven, 1990). Cochlostoma cantabricum Raven in coll. UPV. Description Shell up to 12.5 Ö 5 mm with 7.5 to 8.5 quite rounded whorls. Early whorls with a peripheral angle which is slightly apparent next to it; body whorl de®nitely constricted, well rounded. Sculpture of weak wrinkles on the ®rst embryonic half whorl, then grading to crowded (25±30/mm) ribs on the second whorl. Spire whorls with alternating very strong ribs (9±11 ribs/mm) with 1± 4 ®ner ones; ribs de®nitely thickened at their termination along the suture, so as to give it a crenulated aspect. Aperture strongly thickened and expanded into a collar, with a very distinct rim forming a sharp angle inside the outer lip. Peristome distinctly auriculated, gradually narrowing at the columellar insertion; collar usually contained in a plane, not distorted. Shell colour of a uniform pale brown to tan. Peristome white. Female and male genital systems as in general description. Remarks This species is easily recognized by its pattern of alternating strong and thin ribs. Cochlostoma asturicum, which is found sympatrically in the Picos de Europa area, is similar in general shape and size, but has equal ribs and a darker shell colour. Several characters are shared with the eastern Pyrenean species C. nouleti: the alternating sculpture, the wrinkled pattern on the very early part of the spire, the de®nite inner rim of the aperture, and among the allozymic characters the SOD and MPI patterns. Habitat Among limestone, mostly among mounds of loose large stones in shaded places. The partitioning of the habitat is clearcut where the species is sympatric with C. hidalgoi; the latter living higher on exposed surfaces (®gure 34). Cochlostoma bicostulatum is more ubiquitous and sometimes very abundant in the coastal area, where it is often found alone. Distribution The coastal areas of the Basque country, Cantabrian range and Asturias. This species is predominant at lower altitudes, and can be found only a few metres away from the maritime splash zone if limestone is present.Published as part of Gofas, Serge, 2001, The systematics of Pyrenean and Cantabrian Cochlostoma (Gastropoda, Cyclophoroidea) revisited, pp. 1277-1369 in Journal of Natural History 35 (9) on pages 1317-1319, DOI: 10.1080/002229301750384301, http://zenodo.org/record/527727
Teretia megalembryon Ortega & Gofas 2019, n. comb.

Mangilia sericifila var. strongyla Dall, 1927: 29, n. syn. MATERIAL EXAMINED. — 8 sh., DW130. REMARKS Apart from being slightly larger, we cannot see any speciesspecific difference between the syntype of Teretia strongyla figured by Horro & Rolán (2017: 147), the Azorean type specimen of Pleurotomella megalembryon figured by Dautzenberg & H. Fischer (1896) and our material and therefore consider these as synonyms. This is therefore another amphiatlantic species, recorded from off Georgia (Dall 1927), the Azores (Dautzenberg & Fischer 1896) and the northern part of Bay of Biscay (Bouchet & Warén 1980), and new to Spanish waters.Published as part of Ortega, José Rafael & Gofas, Serge, 2019, The unknown bathyal of the Canaries: new species and new records of deep-sea Mollusca, pp. 513-551 in Zoosystema 41 (26) on page 540, DOI: 10.5252/zoosystema2019v41a26, http://zenodo.org/record/372602

Microvoluta tessellata Ortega & Gofas 2019, n. sp.

Paratypes. 5 immature sh., MNHN-IM-2000-34270, all from SEAMOUNT 2 DW130. TYPE LOCALITY. — Off NW Gran Canaria, 28°08.95’N, 15°53.11’W / 28°09.06’N, 15°52.92’W, 655- 660 m. ETYMOLOGY. — From the Latin tessella, a piece of mosaic, alluding to the sculpture. DESCRIPTION Shell whitish, consisting of 4.5 quite convex whorls, with a well marked, almost channelled suture; protoconch of one globular smooth whorl; teleoconch with oblique axial ribs of which 24 on the last whorl; spiral sculpture of rather deep grooves, rather obsolete on the first whorl and becoming more accentuated on the last whorl; grooves regularly spaced and forming granules at their intersections with the axial ribs. Aperture rather wide, somewhat arched. Three columellar folds, bulging into the aperture, occupying more that 3/4 of the apertural height, the remaining area in the adapical part of the columella somewhat concave; the adapical columellar fold is most developed and the abapical one is very slight; outer lip thin, siphonal canal short. Dimensions of holotype: 6.7 mm height × 2.8 mm diameter. REMARKS This species resembles in many respects Microvoluta superste s Bouchet & Warén, 1985, described from Gorringe Bank, off SW Portugal, but is less slender, more fusiform with the whorls not definitely shouldered as in M. superstes. Spiral sculpture is evenly developed over all the surface of the teleoconch, contrary to M. superstes which has smooth ribs in the median part of the whorls in most specimens. All shells are empty. A preliminary sorting of a large material from Ampère seamount, Josephine seamount and the Meteor group of seamounts collected during the SEAMOUNT 1 and SEAMOUNT 2 cruises revealed several undescribed congeneric species which are currently under study, with a differentiation between banks which may parallel that of Trituba Jousseaume, 1884, as described by Gofas (2003). Because no animal is available, the generic placement is only tentative.Published as part of Ortega, José Rafael & Gofas, Serge, 2019, The unknown bathyal of the Canaries: new species and new records of deep-sea Mollusca, pp. 513-551 in Zoosystema 41 (26) on page 536, DOI: 10.5252/zoosystema2019v41a26, http://zenodo.org/record/372602
