The study of Onychiuridae from 42 caves of the north of the Iberian Peninsula and southwestern France has revealed the existence of 32 species inhabiting the caves of the Basque bio-speleological district, among which four new species are described: Deuteraphorura bizkaiensis sp. nov., Deuteraphorura bolivari sp. nov., Onychiurus arbailakensis sp. nov. and Protaphorura leitzaldeaensis sp. nov. Furthermore, three species, Deuteraphorura boneti (Gisin, 1953), Deuteraphorura akelaris (Jordana & Beruete, 1983) and Spinonychiurus vandeli (Cassagnau, 1960), are redescribed based on type and new material to furnish the description of some characters, especially concerning the chaetotaxy, not considered in the original description. Keys to the recorded species are also reported.

Incorrect Data

Two plant-inhabiting species of Mediolata were collected in the Iberian Peninsula during biodiversity assessments between 2000–2002. Mediolata roigi, sp. nov. and M. chanti Gonzalez were collected in Spain and Portugal respectively. The studies were conducted in citrus orchards in Portugal and apple orchards and vineyards in Spain. Because of some incorrect data in the original description of M. chanti, it is re-described. Eupalopsis vandergeesti Gomaa & Bolland is revealed to be a junior synonym of M. chanti and Mediolata mirus Chaudhri et al. is transferred to the family Eupalopsellidae under the genus Exthothoris. A key to the known species of the genus Mediolata is provided.

A New Species

Phymaraphiniidae Schrammen 1924 (Porifera: Astrophorina) is a family of lithistid demosponges that has received little attention in the past decades. The systematic problems within this family have not been addressed for a long time due to the absence of new records and material. The genus Exsuperantia Özdikmen 2009 was first described by Schmidt (1879) as Rimella to allocate the species Rimella clava, found in the Caribbean. In 1892, Topsent found what he thought to be the same species described by Schmidt in the Azores, and synonymized it with Racodiscula clava, as he thought this species belonged to the family Theonellidae Lendenfeld 1903. However, Rimella and Racodiscula belong to distinct families: Rimella to Phymaraphiniidae, and Racodiscula to Theonellidae. Due to the fact that the genus Rimella was already preoccupied by a gastropod, it was renamed as Exsuperantia. In result of the poor preservation of Schmidt’s material and the absence of new specimens, the attribution of Topsent’s specimens to the family level remained obscure. Here, we review the genus Exsuperantia based on the analysis of new material recently collected during various research expeditions in the northeast Atlantic Ocean. The comparison of these new specimens with Schmidt’s and Topsent’s type material, allowed us to assign Topsent’s specimens to a new species, Exsuperantia archipelagus sp. nov., and confirm its attribution to the family Phymaraphiniidae (not Theonellidae). Phylogenetic reconstructions using newly generated sequences of the cytochrome subunit (COI) marker also support the assignment of the new species to the family Phymaraphiniidae (not Theonellidae).

Stratigraphic Range

Silurian ramphoprionid polychaete annelids, represented by their jaws (scolecodonts), are described from extensive collections from Gotland, Sweden. The family Ramphoprionidae, monotypic at its original description, is sub-divided into four genera; Protarabellites Stauffer, 1933; Ramphoprion Kielan-Jaworowska, 1962; “Pararamphoprion” Männil and Zaslavskaya, 1985; and Megaramphoprion new genus. Identified species include “P.” cf. nordicus Männil and Zaslavskaya, 1985; P. rectangularis new species; P. staufferi new species; P. triangularis new species; and two Protarabellites species left in open nomenclature. Ramphoprion is represented by one new highly plastic species, R. gotlandensis, housing five distinguishable morphotypes showing gradual evolution. Megaramphoprion, which is most closely related to Ramphoprion, is represented by M. magnus new genus and species, a rare but distinctive taxon. Most species have long stratigraphic ranges within which important morphological changes can nonetheless be observed. The stratigraphic range of ramphoprionids includes, at least, the Ordovician to the Silurian. They are fairly rare in the Silurian of Gotland and where present they generally form less than 10 percent of the polychaete faunas, although occasionally reaching as much as 20 to 30 percent. Evolution, paleoecology, and surface structures of the investigated species are briefly discussed.

Two new species of Ischnomesidae, Haplomesus celticensis sp. nov. and Haplomesus hanseni sp. nov. are described from the southwest of Ireland and the Argentine Basin respectively. Both species lack the expression of pereopod VII, a characteristic that we argue is produced by progenesis, not neoteny as suggested by Brökeland & Brandt (2004). Haplomesus angustus Hansen, 1916 and Haplomesus tropicalis Menzies, 1962, also lack pereopod VII and are revised from the type material. The original description of Haplomesus angustus Hansen, 1916 describes the adult type specimen as a juvenile; the original description of Haplomesus tropicalis Menzies, 1962 fails to mention the lack of pereopod VII. Progenesis is discussed for the above species and within the family Ischnomesidae as a whole.

The discovery of a new genus of Heatherellidae in New Zealand has led us to revise this enigmatic family and its constituent genera. Aheatherella n. gen., based on A. mira n. sp. from the North Island of New Zealand, lacks some of the derived character states that link the Australian Heatherella, most notably the lack of sexual dimorphism in the dorsal shields and in the presence of peritremes in adult Aheatherella. Heatherella osleri n. sp. is described from New South Wales, extending the distribution of this genus beyond Queensland. New collection records of H. callimaulos and a key to the genera and species of the family are provided. We propose that the Heatherellidae—previously placed in its own cohort outside the Gamasina—are best considered a superfamily of gamasine mites within the subcohort Epicriiae.

Calathiscus tantillus new genus & new species (Scleractinia, Poritidae) is described from several specimens collected along the north coast of the Sultanate of Oman and Masirah Island. The zooxanthellate genus has a massive growth form, although colonies remain very small (< 40 mm). The skeletal characteristics are intermediate between Porites and Goniopora, with calices averaging 1.7 mm in diameter. The polyps, fully extended during the day in most specimens, have a long tubular column topped by a wide conical oral disc surrounded by 15 22 tentacles. The characteristics of this new species and genus are discussed in relation to other genera in the family: Porites, Goniopora, Stylarea, Alveopora and Poritipora.

The recent rediscovery of specimens of the Baikalian lumbriculid Pseudorhynchelmis olchonensis (Burow et Koshow, 1932) led to the re-examination of (1) Michaelsen’s hundred-year-old type specimens of Lycodrilus parvus, assumed, for a long time, to have been wrongly attributed to the Tubificidae instead of the Lumbriculidae, and of (2) type specimens used by Hrabě (1982) for his redescription of Lycodrilus parvus and its combination with the newly, subsequently created genus Pseudolycodrilus Hrabě, 1982. Surprisingly enough, the original description of Pseudolycodrilus parvus (Michaelsen, 1905) proved to be based on a mixing of two different species, P. parva and Pseudorhynchelmis semernoyi sp. nov., both of which are herein assigned to the recently re-established genus Pseudorhynchelmis Hrabě, 1982. As a result, the genus Pseudolycodrilus is invalidated and must be considered as a synonym of Pseudorhynchelmis. P. parva and P. olchonensis are re-described on the basis of neotypes and lectotypes, respectively. P. semernoyi sp. nov. is distinguished from other Pseudorhynchelmis by having a conical prostomium, a well-marked clitellum with a honeycomb-like structure, and genital, sucker-like papillae, associated with penial setae. The description of the new species P. semernoyi, plus a re-evaluation of P. olchonensis, called into question the taxonomical status of Pseudorhynchelmis dissimilis (Semernoy, 2004). This study provides new examples of genital setae in the Lumbriculidae although this character remains exceptional within the family.

Abstract Based on material collected during the BIOICE project off Iceland, the taxonomy and distribution of seventeen species (11 genera) of polychaetous annelids belonging to the family Ampharetidae (Annelida; Polychaeta) is reviewed. Eleven of these species were previously reported in the area or nearby areas: Amage auricula, Anobothrus gracilis, Glyp-hanostomum pallescens, Grubianella klugei, Lysippe fragilis, L. labiata, L. sexcirrata, L. vanelli, Samythella elongata, Sosane bathyalis and S. wireni. Five species, Amage benhami, Melinnampharete eoa, Noanelia hartmanae, Ymerana pteropoda and Zatsepinia rittichae, either never or only once reported after original description, are redescribed or discussed. A potentially new species, Amage sp., is described but not named because only one specimen is present. Several body characters of high taxonomic relevance in Ampha-retidae are reviewed using SEM. The distribution of each species off Iceland is provided.
