Preliminary Phylogenetic Analysis

New sponge species belonging to the closely related fistular genera Zyzzya, Cornulella, Damiria, and Acheliderma are described from reef habitats off the coasts of Colombia, Bonaire and Curaçao in the southern Caribbean. With very few exceptions these sponges are small to tiny specimens inhabiting crevices and other cryptic habitats; some may be excavating. For comparison both published and unpublished material belonging to these genera from other parts of the world was examined, and this yielded several nomenclatorial changes and a further three new species from the Indian Ocean. The new species are: Zyzzya invemar (Caribbean), Cornulella santamartae (Caribbean), C. tyro (Seychelles), C. amirantensis (Seychelles), Damiria leonorae (Caribbean), D. toxifera (Seychelles) and Acheliderma lisannae (Caribbean). All species belonging to these genera, as well as to the closely related Indo-Pacific genus Paracornulum, are briefly diagnosed. The genera and species of this group are found to be distributed over tropical and subtropical waters of all three oceans. The five genera were so far of controversial systematic allocation, although their close relationship with Cornulum was generally accepted. The recently revived family Iophonidae is demonstrated to be the likely assemblage for them. A brief survey of Iophonidae genera is presented and a preliminary phylogenetic analysis of the fistular genera is attempted. Although several parts of the phylogenetic relationships remain unsolved, it is nevertheless clear that in all genera the closest relatives are not found in adjacent areas, but are often disjunct.

Mascarene Archipelago

Many regions of the world remain unexplored in terms of the tardigrade diversity, and the islands of the Indian Ocean are no exception. In this work, we report four species of the family Echiniscidae representing three genera from Mauritius, the second largest island in the Mascarene Archipelago. Two species belong in the genus Echiniscus: Echiniscus perarmatus Murray, 1907, a pantropical species, and one new species: Echiniscus insularissp. nov., one of the smallest members of the spinulosus group and the entire genus, being particularly interesting due to the presence of males and supernumerary teeth-like spicules along the margins of the dorsal plates. The new species most closely resembles Echiniscus tropicalis Binda & Pilato, 1995, for which we present extensive multipopulation data and greatly extend its distribution eastwards towards islands of Southeast Asia. Pseudechiniscus (Meridioniscus) mascarenensissp. nov. is a typical member of the subgenus with elongated (dactyloid) cephalic papillae and the pseudosegmental plate IV’ with reduced posterior projections in males. Finally, a Bryodelphax specimen is also recorded. The assemblage of both presumably endemic and widely distributed tardigrade species in Mauritius fits the recent emerging biogeographic patterns for this group of micrometazoans.

Four apseudomorph tanaidaceans are recorded from benthos of the shelf off Angola and off northern Namibia (SouthWest Africa). Of these, three are new to science, one each in the genera Hemikalliapseudes, Calozodion andApseudopsis. The genus Hemikalliapseudes now contains four species, all described from West Africa (Angola andMauretania). The new species Hemikalliapseudes sebastiani sp. nov. is separated from other species of this genus byfeatures of several appendages, and the shape of the cephalothorax, pereonites and telson. The genus Calozodion ismainly distributed in the Atlantic and also in the Indian Ocean. Calozodion dominiki sp. nov. is the tenth representativeof the genus and is readily distinguished from all others in that the cheliped propodus of the male has only smallprocesses proximo-ventrally. The new species was widely distributed in the investigation area. Apseudopsis cuanzanussp. nov. is a new member of this species-rich and widely-distributed genus. It differs from the other species of this genusby a combination of several morphological features, including the absence of a dorsodistal spine on the pereopod 1merus, the lack of anterolateral spines on the pereonites, the shape of rostrum and by the absence of plumose setae on pereopod six basis.

Among the numerous littoral Alcyonarians collected by the Royal Indian Marine survey ship Investigator in the Indian Ocean there are five small Siphonogorgids of exceptional interest and apparently new to science. As some time must elapse before the publication of the complete memoir on the Indian Ocean collection, it seems advisable to make a separate report on these new forms. In so doing, I must acknowledge my indebtedness to Professor A. Alcock, F.R.S., and Professor J. Arthur Thomson, M.A., F.R.S.E., University of Aberdeen, for the opportunity of studying these interesting forms, and to the latter also for much kind advice and encouragement.

A new genus of Sycophaginae (Hymenoptera: Agaonidae), Sycidiphaga Liu, Rasplus & Huang n. gen., is described with a single new species, S. cyrtophyllae Liu, Rasplus & Huang n. sp. This species was discovered in Yun Nan and Gui Zhou, China and is associated with Ficus cyrtophylla (Moraceae, Ficus, subgenus Sycidium). The new taxon is readily distinguished from other genera of Sycophaginae by: 1) the presence of a conspicuous interantennal blade-like projection that extends well above the level of the toruli; 2) an inflated parastigma surrounded by a slight infuscation of the wing membrane; 3) the presence of a long and conspicuous median sulcus on the male pronotum; and 4) the presence of dense and long pilosity on the wings. Illustrations and a diagnosis and description of Sycidiphaga are provided, as is a key to the world genera of Sycophaginae. The phylogenetic position of Sycidiphaga was demonstrated through sequencing four gene regions of COI, Cyt b, 28s D3-D5 and EF-1α genes and conducting a phylogenetic analysis of available sequences for the subfamily. Sycidiphaga cannot be placed with confidence within Sycophaginae but several discussed characters suggest a close relationship with Idarnes Walker and Sycophaga Westwood.

A taxonomic study of the Hymenasplenium unilaterale subclade (Aspleniaceae) is presented based on morphological and molecular evidence. Twelve species are recognized, nine of which are described as new. The nine new species include H. kinabaluense, H. solomonense, H. madagascariense, H. nigricostatum, H. neocaledonicum, H. oligosorum, H. queenslandicum, H. samoaense, and H. vanuatuense. Of the 12 species recognized, one occurs in Malaysia, East Africa, and Reunion, one in southern Vietnam, and the rest restricted to 1–2 islands of the Indian Ocean or the Pacific Ocean. These new species have been erroneously treated as H. unilaterale by earlier pteridologists. All species were included in a recent phylogenetic analysis and supported as distinct lineages based on molecular data. A key to the species and information on their distributions, habitats, and major distinguishing characters are provided.

The Indo-West Pacific sparid genus Argyrops is reviewed, with four valid species and three new species: A. bleekeri Oshi-ma, 1927, A. filamentosus (Valenciennes, 1830), A. megalommatus (Klunzinger, 1870), A. spinifer (Forsskål, 1775), A. caeruleops n. sp., A. flavops n. sp. and A. notialis n. sp. The above seven species can be differentiated on meristic values, ontogenetic and morphological characters, and coloration. Argyrops bleekeri from the western Pacific and A. notialis n. sp. from Western Australia both have only one rudimentary dorsal-fin spine on the first dorsal pterygiophore (which defines the Argyrops bleekeri complex), while the five other congeners have two rudimentary dorsal-fin spines, both associated with the first dorsal pterygiophore. Argyrops filamentosus, A. megalommatus, and A. caeruleops n. sp. have the 3rd dorsal-fin spine filamentous and longest, the defining character of the A. filamentosus complex. Argyrops spinifer (from the Indian Ocean) and A. flavops n. sp. (from the Middle East to Pakistan, but not the Red Sea and probably rare in the Persian Gulf) differ from other complexes in having 4–6 elongated or filamentous dorsal-fin spines (usually 3rd–6th [four spines] or 3rd–8th [six spines]) in juveniles and subadults, with the first 2 dorsal-fin spines rudimentary, the characteristic of the A. spinifer complex. The above three complexes include the seven Argyrops species that are defined and supported by morphological and color differences, genetic distinctions (partial cytochrome b genes, 1,116 bp), and distribution. The nominal species are discussed, together with several geographic variations of A. spinifer from the Indian Ocean, and a key to the species is provided.

Three new species of Polycystididae are described: Brachyrhynchus triplostylis n. gen. n. sp., B. acutus n. sp. and B. oosterlyncki n. sp. They are the first species of Polycystididae to be described with a second, single-walled accessory stylet connected to a small glandular vesicle in the male system. The three species can be distinguished from each other by the detailed morphology and the relative lengths of the three stylets in the male system. The relationships of these species with other representatives of Polycystididae are discussed.

The particularly speciose cheilostomate genus Microporella includes taxa whose maternal zooids and associated ovicells present a personate structure, i.e. a particularly developed peristome. Six species of Microporella with personate ovicells are analysed from material sampled in the Indian Ocean, Red Sea and southeast Mediterranean. Consideration of highly diagnostic tiny morphological characters displayed by the primary orifice and the avicularium has made it possible to distinguish three new species, M. browni n. sp., M. maldiviensis n. sp. and M. collaroides n. sp., and to better characterise the other species. Among the latter, two species named by Audouin (1826) from Savigny’s drawings (1817), M. coronata and M. genisii, are redescribed and neotypes are selected. Additionally, a new species of the M. coronata species group, Microporella hastingsae n. sp., is proposed following examination of a museum specimen recorded as M. ciliata var. coronata (Hastings 1927). The species dealt with in this study revealed remarkably different patterns of geographic distribution, possibly showing different potential for natural and/or anthropogenic dispersal. The bryozoan assemblages sampled along the coast of Lebanon include four of the six studied species, at least three of them presumably non-indigenous including M. harmeri Hayward, which displays a remarkably wide distribution from the Indian Ocean to the West Pacific and the East Atlantic (Canary Islands).
