AbstractThe bryozoan family Chlidoniopsidae Harmer, 1957 is reviewed in relation to a new Paleogene European fossil, Celiopsis vici new genus and new species. It differs from the type and only other genus of the family in having longer internodes with up to three zooids, shorter proximal caudae, and, more importantly, suture lines that unequally divided the umbonuloid frontal shield and basal (abfrontal) wall (and the hypostegal coelom in life) into sectors, analogous to the situation in the lepralioid-shielded Prostomariidae and Urceoliporidae. Unlike Prostomaria and Urceolipora, and like Chlidoniopsis, Celiopsis is uniserial. The suture lines in Celiopsis were lines of insertion (attachment) of epithecal membranes in life and each sector has its own longitudinal series of septular pores, sometimes doubled. Miocene to Recent Chlidoniopsis contains two species, and Eocene–Oligocene Celiopsis contains three species. The geographic distribution gives evidence of origination of the family in the Paratethys of Europe, with southeastwards migration to Australia and the tropical western Pacific. The temporal distribution suggests two macro-evolutionary trends—from multizooidal to unizooidal internodes, and from a broader area of basal wall, with a division into separate cryptocystal fields, to a narrower basal wall with no such division.

A new genus and species of glass sponge, belonging to the family Pheronematidae, is described from a single specimen collected from a seamount near Yap Trench in the western Pacific Ocean. Pheronemoides fungosus gen. et sp. nov. is described based on external morphology. In Pheronemoides gen. nov. the basalia are grouped in a broad semicircular tuft attaching to the dermal surface, and marginalia are located on the boundary between the atrial and dermal surfaces. Given the positions of the basalia and the marginalia, we recognize Pheronemoides as a transitional genus between Pheronema and Sericolophus. We also used a partial sequence of the 16S rDNA gene to confirm the validity of the new species designation.

General Appearance

Bruceopsis n. gen. is established for two species, Bruceopsis projectus n. gen., n. sp., and Bruceopsis guamensis n. gen., n. sp., both from Guam, Mariana Islands, in the tropical western Pacific. The new genus is characterised by having the eyes at least partly covered dorsally and laterally by orbital hoods, the latter with sharp or blunt teeth; the chelipeds equal or unequal in size, symmetrical or asymmetrical in shape, carried extended, moderately or feebly enlarged, with carpus and merus bearing rows of setae mesially, and with simple chelae, lacking a snapping mechanism on the fingers; the third to fifth pereiopods with dorsally notched dactyli; the first to fourth pereiopods with small dorsolateral coxal lobes; the second pleomere conspicuously enlarged in females; and the posteroventral angle of the sixth pleonite with a welldeveloped, sometimes projecting articulated plate. Bruceopsis n. gen. resembles Alpheopsis Coutière, 1896 in general appearance, but may be more closely related to the western Atlantic genera Coutieralpheus Anker & Felder, 2005 and Harperalpheus Felder & Anker, 2007.

First Time

The family of mygalomorph spiders Paratropididae Simon, 1889 is here reported for the first time for Colombia, where it is represented by three genera (Anisaspis, Paratropis, Stormtropisgen. n.) and eight species. One genus, Stormtropis, and six species constitute new taxa that are here diagnosed, described and illustrated. The geographical distribution of Paratropispapilligera FO Pickard-Cambridge, 1896 and Paratropiselicioi Dupérré, 2015 are also redescribed and expanded on the basis of new material examined. The diagnosis of the subfamily Paratropidinae, Paratropis Simon, 1889 and Anisaspis Simon, 1892 are emended including the variations of the new species. Likewise, a geographic distribution map for the entire family and a taxonomic key for the males of Paratropidinae are included. Other biogeographic, morphological, and taxonomic aspects are discussed.

History Of

The bogidiellid amphipod crustaceans Stockigi diella aequim ana new genus and species and Om angidiella p arvid actyl a new genus and species are described from subterranean groundwater habitats in the Sultanate of Oman on the Arabian Peninsula. Stockigidiell a is easily distinguished by a row of long, deeply bifid setae on pereopods 5 and 6, whereas Omangidiell a is distinguished by a greatly reduced propodus of gnathopod 2 and elongate oostegites; it also possesses a third coxal lobe on the maxilliped, a unique character noted only in three other bogidiellid genera from northern and eastern Africa. At present, the family Bogidiellidae contains 35 genera and 105 species but a significant number of provisionally recognized new species and possibly several new genera await description. The geographic distribution of the family Bogidiellidae is nearly circumglobal, but species tend to be clustered in discontinuous regions. A number of important questions regarding the origin and biogeographic history of the family remains unanswered.

Dental Ontogeny

An exceptionally well-preserved silicified bivalve from the Upper Permian of Texas is described and assigned to a new genus and species,Cassiavellia galtarae, placed in the family Bakevelliidae. The species represents one of the earliest and best characterized unequivocal occurrences of the multivincular ligament in the superfamily Pterioidea. The silicified material provides a wealth of information on the morphology of inadequately known Paleozoic pterioideans, including hitherto undescribed aspects of the larval shell, auricular sulcus, muscle scars, and dental ontogeny. The discovery of the condyle-fossa complex on the anteroventral shell margin, a feature previously undescibed in Bivalvia, raises the question of the homology and taxonomic significance of the problematic subumbonal ridge-like structures in Pterioidea. In life,C. galtaraewas probably an epifaunal right-pleurothetic bivalve, byssally attached to hard or raised flexible substrata. In addition toC. galtarae, another new species,C. nadkevnae, is placed inCassiavellia.

A New Species

Pareiorhaphis nasuta, a new neoplecostomine catfish of the family Loricariidae is described. The species was collected from headwaters of the rio Matipó, tributary of the upper rio Doce basin in State of Minas Gerais, Brazil. The new species is readily diagnosed from all remaining congeners by the longer snout and by the smaller orbital diameter. The new species is the first representative of the genus Pareiorhaphis discovered in the rio Doce basin, thus expanding its geographic distribution. A phylogenetic diagnosis for Pareiorhaphis is presented.
