Taringa

Abstract: Received 12.03.2020; accepted 13.05.2020; published online 30.06.2020 In the present paper, two sea slug species, Biuve fulvipunctata (Baba, 1938) (Gastropoda Cephalaspidea) and Taringa tritorquis Ortea, Perez & Llera, 1982 (Gastropoda Nudibranchia), are reported for the second time in the Ionian coasts of Sicily (Italy). Biuve fulvipunctata is an Indo-West Pacific cefalaspidean, previously reported for Italian territorial waters only in Faro Lake (Messina, Sicily). Taringa tritorquis is a species originally described for Canary Islands and hitherto found in Sicily and probably in Madeira. Both species are easily identifiable for their characteristic external morphology. Indeed, B. fulvipunctata shows a W-shaped pattern of white pigment on the head, while T. tritorquis presents rhinophore and gill sheaths with spiculous tubercles crown-shaped and an orange-yellowish body coloring. Since B. fulvipuctata has been previously reported in Faro Lake, probably, the specimen reported in this note could have been taken in veliger stage through the Strait of Messina currents. Otherwise, the veliger has been carried attached to the keel of boats. Instead, it is still unclear if T. tritorquis could be a native or non-indigenous species of the Mediterranean Sea. Indeed, due to its small size and its sciaphilous behavior, it might be a rare species, overlooked until now.

Abstract: A new dorid nudibranch from the southern Iberian peninsula is described. Taringa tarifaensis n. sp. is subtidal and has been found under stones. A comparison between T. tarifaensis and the other known species of the genus is presented, as well as some remarks on the taxonomic status of the genus Taringa.

Abstract: It Nella presente nota vengono studiate la morfologia e la anatomia macroscopica di tre individui adulti di una nuova specie mediterranea di Nudibranchi doridiani: Taringa pinoi nov. sp. Viene descritta la morfologia del nidamento e sono esaminati numerosi aspetti comportamentali di Taringa pinoi. Segue una discussione comparata sul genere Taringa. Il genere viene collocato nella famiglia Discodorididae. En In the present paper the morphology and gross anatomy of three adult specimens of a new mediterranean species of dorid Nudibranchs, Taringa pinoi nov. sp., are studied. The morphology of an egg mass is here described and many aspects of the behaviour of Taringa pinoi are examined. A compared discussion on the genus Taringa is here reported. The genus has been placed in the family Discodorididae.
