Redescription of Bedotella armata from Biscay Bay, northern Spain, the type species of Bedotella Stechow, 1913 (Cnidaria, Hydrozoa, Lafoeidae), with …

The circalittoral and bathyal genus Bedotella, comprising a unique known species endemic to the North European Atlantic (Lusitanian Province), Bedotella armata (Pictet, C. & M. Bedot, 1900) is redescribed based on a specimen from the Bay of Biscay, North Spain. As the holotype of the species, originally described as Campanularia armata, is sterile and incomplete, the present re-description includes new data concerning its morphometry, including gonothecae, and cnidom, as well as all the literature. The diagnostic characters of Bedotella armata are the presence of globular nematothecae, the campanuliform hydrothecae, and flabelliform, gigantic gonothecae. We corroborate the hypotheses of aff…
Partially disarticulated new Miocene burrower bug (Hemiptera: Heteroptera: Cydnidae) from Cerová (Slovakia) documents occasional preservation of terr…

The state of preservation of the bug Sehirus carpathiensis J.A. Lis, Vršanský & Schlögl, sp. n. (Hemiptera: Heteroptera: Cydnidae) from the Lakšárska Nová Ves Formation at Cerová (Slovakia) supports extremely rapid sinking and burial in upper bathyal Early Miocene sediments. The specimen originated from land at most a few kilometers away, but transport via a river can be excluded as the head and wings are still attached. Its most likely source based on fossil flora and the habitat of several living representatives of the genus is a riparian habitat in an adjacent area of land. Phylogenetically the new species is closely related to both Oligocene and living representatives of the genus, thus…
Late Quaternary marine ostracods of the Basque Basin (S Bay of Biscay): taxonomy and distribution
2018
Late Quaternary taxonomy and ecologic and age distributions of ostracods from the Basque Basin (S Bay of Biscay) are described. More than forty-four thousands ostracod specimens have been obtained from one hundred surface samples and core samples from six cores located in shelf and upper bathyal depths and other infrabathyal core as comparative deep reference. A total of 155 species have been taxonomically described, belonging to 67 genera. Most characteristic species (123) have been SEM figured, and ecologic-geographic distributions and ages have been provided for all species. The resulting database will be a useful help for palaeoceanographic and palaeoclimatologic studies of the region.
