Flabellina rubrolineata was believed to have a wide distribution range, being reported from the Mediterranean Sea (non-native), the Red Sea, the Indian Ocean and adjacent seas, and the Indo-West Pacific and from Australia to Hawaii. In the present paper, we provide a redescription of Flabellina rubrolineata, based on specimens collected near the type locality of this species in the Red Sea. The morphology of this species was studied using anatomical dissections and scanning electron microscopy. To place this species in the phylogenetic framework and test the identity of other specimens of F. rubrolineata from the Indo-West Pacific we sequenced COI, H3, 16S and 28S gene fragments and obtained phylogenetic trees based on Bayesian and Maximum likelihood inferences. Our morphological and molecular results show a clear separation of F. rubrolineata from the Red Sea from its relatives in the Indo-West Pacific. We suggest that F. rubrolineata is restricted to only the Red Sea, the Arabian Sea and the Mediterranean Sea and to West Indian Ocean, while specimens from other regions belong to a complex of pseudocryptic species.

FRANSEN Naturalis Biodiversity Center, P.O. Box 9517, 2300 RA Leiden, The Netherlands. E-mail: [email protected] Abstract A new species of pontoniine shrimp belonging to the ‘Periclimenes obscurus species group’ is described from the Berau Islands, North East Kalimantan, Indonesia. Specimens were obtained from aglaopheniid hydrozoans of the genus Macro- rhynchia. The new species is here described and figured. Its affinities with related species are discussed and a DNA-bar- code is provided. Key words: Crustacea, Decapoda, Palaemonidae, Pontoniinae, Periclimenes, new species, Hydrozoa, East Kalimantan, DNA-barcode, symbiont Introduction Within the large pontoniine genus Periclimenes Costa comprising over 150 species (De Grave & Fransen 2011), several species groups have been recognized. For some of these groups new genera were erected, e.g. Ancylomenes Okuno & Bruce, 2010 for the ‘Periclimenes aesopius species group’. For several of these species groups however, no solid morphological synapomorphies have been found to classify them in their own genus. Examples are the ‘Periclimenes iridescens species group’ known from the Atlantic and first distinguished by Heard & Spotte (1991), the ‘Periclimenes diversipes species group’ designated by Bruce (1989), the ‘Periclimenes granulimanus species group’ designated by Ďuriš (2010), and the ‘Periclimenes obscurus species group’ which was designated by Bruce (1987).

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.

In comparison to other invertebrates, TAXONOMIC ENUMERATION hydroids are one of the least known groups of marine animals from the coast of Pakistan Haque Family BOUGAINVILLIIDAE (1977) reported a few Cnidaria from the Pakistani Genus HYDRACTINIA Van Beneden, 1841 coast including two hydroids i.e. Plumularia flabellum Allman, 1883 (= P. insignis Allman, 1. Hydractinia epidocleensis Leloup, 1931 1883) and Campanularia juncea Allman, 1874 (= (Fig. 1) Thyroscyphus junceus (Allman, 1876) from Keamari and Bhit Island, Karachi, respectively. Ahmed and Hameed (1999), Ahmed et al. (1978) and Haq et al. (1978) have mentioned the presence of hydroids in various habitats along the coast of Pakistan.
