Three New Species

Three new species are described from the Comoros, an archipelago in the Indian Ocean: Teratothyasides scutulatus Smit & Pesic n. sp., Platymamersopsis comoros Smit & Pesic n. sp. and Atractides comorosensis Smit & Pesic n. sp. One species is reported new for the fauna of the Comoros, i.e. Monatractides ventriosa (K. Viets, 1916).

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.

Three New Species

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.

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.

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

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 Tropics

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).

AbstractMorphological, life history, and distributional data are presented for North American species of the subgenus Stygomomonia (sensu stricto) Szalay, 1943. Adults of the seven previously recognized species are redescribed, and deutonymphs of five of these species are described for the first time. Two species, S. (s.s.) neomexicana Cook and S. (s.s.) occidentalis Cook are substantially revised on the basis of an examination of the types and extensive series of newly collected specimens. Three new species are described, S. (s.s.) californiensis on the basis of deutonymphs and adults, and S. (s.s.) imamurai and S. (s.s.) cooki on the basis of adults. A new diagnosis of the subgenus is proposed and discussed, the relationships of the various species are discussed, and a key to deutonymphs and adults of North American species is presented. New distributional data are presented for all species, and dispersal patterns from Pleistocene refugia are discussed.

A New Species

Based on a census of the polychaete fauna of the Socotra Archipelago in the Indian Ocean we report here new findings on the genus Syllis Savigny in Lamarck, 1818. These ten species are newly recorded from this area: Syllis alternata Moore, 1908; Syllis bouvieri Gravier, 1900; Syllis broomensis (Hartmann-Schröder, 1979); Syllis compacta Gravier, 1900; Syllis crassicirrata (Treadwell, 1925); Syllis gerlachi (Hartmann-Schröder, 1960); Syllis hyalina Grube, 1863; Syllis lutea (Hartmann-Schröder, 1960); Syllis schulzi (Hartmann-Schröder, 1960); Syllis ypsiloides Aguado, San Martín & Ten Hove, 2008. Additionally, Syllis qamhiyn sp. nov. is described as a new species, characterized by its conspicuously thick and short dorsal cirri filled with a gelatinous substance and reduced number of compound chaetae from medium to posterior parapodia, with enlarged shafts and short blades which become almost unidentate and do not fuse with shafts. Following an examination of the holotype of S. bouvieri, its status as a valid species and not as synonym of Syllis prolifera Krohn, 1852, as considered by some authors (see Licher 1999) is confirmed, and a redescription is included.
