Is Ellipura Monophyletic? a Combined Analysis of Basal Hexapod
ARTICLE IN PRESS Organisms, Diversity & Evolution 4 (2004) 319–340 www.elsevier.de/ode Is Ellipura monophyletic?

Biodiversity Journal, 2020, 11 (4): 861–870 https://doi.org/10.31396/Biodiv.Jour.2020.11.4.861.870 The biodiversity of the marine Heterobranchia fauna along the central-eastern coast of Sicily, Ionian Sea Andrea Lombardo* & Giuliana Marletta Department of Biological, Geological and Environmental Sciences - Section of Animal Biology, University of Catania, via Androne 81, 95124 Catania, Italy *Corresponding author: [email protected] ABSTRACT The first updated list of the marine Heterobranchia for the central-eastern coast of Sicily (Italy) is here reported. This study was carried out, through a total of 271 scuba dives, from 2017 to the beginning of 2020 in four sites located along the Ionian coasts of Sicily: Catania, Aci Trezza, Santa Maria La Scala and Santa Tecla. Through a photographic data collection, 95 taxa, representing 17.27% of all Mediterranean marine Heterobranchia, were reported. The order with the highest number of found species was that of Nudibranchia. Among the study areas, Catania, Santa Maria La Scala and Santa Tecla had not a remarkable difference in the number of species, while Aci Trezza had the lowest number of species. Moreover, among the 95 taxa, four species considered rare and six non-indigenous species have been recorded. Since the presence of a high diversity of sea slugs in a relatively small area, the central-eastern coast of Sicily could be considered a zone of high biodiversity for the marine Heterobranchia fauna.

For more information, please contact [email protected]. INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. -

On a New Genus and Some New Species of Opisthobranchiate Gastropods of the Family Eubranchidae from the Gulf of Mannar^
ON A NEW GENUS AND SOME NEW SPECIES OF OPISTHOBRANCHIATE GASTROPODS OF THE FAMILY EUBRANCHIDAE FROM THE GULF OF MANNAR^ K. PRABHAKARA RAO* Central Marine Fisheries Research Institute, Mandapam Camp, India ABSTRACT A new genus Annulorhina based on the type species A.mandapamensis and three new species mmely Eubranchus mannaremis, Capellinia fuscanmdata, and Eubranchopsis indicus of the ftmily EtbKr.chidae are <lNaJbed from the Indian Ocean.

Chan Members of the nudibranch genus Phestilla are common predators of scleractinian corals, but currently this genus has 10 described species only. Here we describe Phestilla goniophaga sp. nov., the first formally named predatory nudibranch species of the stony corals from the genus Goniopora. The new species can be distinguished from its congeneric species by the large number of long cerata (up to 16 rows and 23 cerata per row), and white rounded hump on the notum. The hump resembles the mouth of the coral poly, while the cerata resemble the coral tentacles. The egg masses of P. goniophaga sp. nov. are unique among Phestilla spp. egg masses in being bright orange in color, and forming a coiled ribbon. -

BOUCHER2 ABSTRACT: The rich opisthobranch fauna of the Marshall Islands has re mained largely unstudied because of the geographic remoteness of these Pacific islands. We report on a long-term collection ofOpisthobranchia assembled from the atolls of Bikini, Enewetak, Kwajalein, Rongelap, and Ujelang . Fifty-seven new records for the Marshall Islands are recorded, raising to 103 the number of species reported from these islands. Aspects ofthe morphology, ecology, devel opment, and systematics of 76 of these species are discussed. THE OPISTHOBRANCH FAUNA OF THE Marshall viously named species are discussed, 57 of Islands, a group of 29 atolls and five single which are new records for the Marshall islands situated 3500 to 4400 km west south Islands (Table 1). west of Honolulu, Hawaii, is rich and varied but has not been reported on in any detail.

Runcina Ferruginea N.Sp. (Cephalaspidea: Opisthobranchia: Gastropoda), a New Runcinid from Great Britain

U.K. (1977) 57, 201-211 201 Printed in Great Britain RUNCINA FERRUGINEA N.SP. (CEPHALASPIDEA: OPISTHOBRANCHIA: GASTROPODA), A NEW RUNCINID FROM GREAT BRITAIN ANNETRUDI KRESS Department of Anatomy, University of Basle, Switzerland (Plates I-II, Figs. 1-4) A new species of the family Runcinidae is described. The name ferruginea reflects the fact that the animal displays a uniform reddish-brown colour. The central tooth of the radula of R. ferruginea is bilobed and each lobe bears about ten slender denticles. The lateral teeth are hook-shaped and show smooth edges. The central tooth of Runcina coronata, the type species, is bilobed also, each lobe carrying only about five denticles but these being of a more prominent character. The lateral teeth have highly denticulated edges. The male copulatory organ consists of three parts. A short penis protruding into an atrium, a prostate gland and a seminal vesicle. The hermaphroditic and female part of the reproductive system consists of ovotestis, spermoviduct, spherical ampulla, fertilization chamber, uterus, albumen gland, mucous gland and a common genital duct leading to the exterior. From this duct a ciliated duct leads to the fertilization chamber. The organization of the reproductive system is basically the same as in R. coronata, the only differences are in the proportions of the different parts mentioned. INTRODUCTION Members of the small suborder Runcinacea have recently been reviewed and efforts have been made to group new findings (Burn, 1963; Baba, 1967; Miller & Rudman, 1968).
