A New Species

Soft-bottom material collected from the northern part of the Sea of Marmara (off Küçükçekmece) included a total of 67 species belonging to 24 polychaete families. Three species (Brania pusilla, Lysidice cf. margaritacea and Sabellaria spinulosa) are new records for the Sea of Marmara. Three alien species (Polydora cornuta, Prionospio pulchra and Pseudopolydora paucibranchiata) were found at the shallow-water stations. Different polychaete assemblages occurred in the area and the mud percentage of sediment and salinity were the main factors related to their distribution. A new Polydora species, which is mainly characterized in having brownish pigmentation solely on the antero-dorsal sides of the body, and falcate major spines with only a bulge (anterior ones) or with a bulge and a small tooth, is described.

Blue Holes

Lying at the southernmost point of the Lucayan Archipelago, the Turks and Caicos Islands are amongst the better studied localities for anchialine cave biodiversity. For nearly five decades, novel invertebrate fauna, comprised primarily of crustaceans, have been collected from these tidally influenced pools – but new findings are always on the horizon. Herein we present new records of crustaceans and annelids from anchialine blue holes and horizontal caves of the Turks and Caicos. These findings include two potentially new species of meiofaunal annelids and a new species of remipede collected from a shallow water cave pool. Our 2019 expedition additionally expands known faunal distributions for several taxa across the Caicos islands, and raises the biodiversity of the region to 35 species, 13 of them considered endemic. This is the first comprehensive faunal list for the anchialine systems in the Caicos Bank.

A New Species

Seventeen species of tardigrades were found in this study. All species are new records for Guizhou Province, including two new records for China (Echiniscus perviridis and Doryphoribius zappalai) and one (Doryphoribius huangguoshuensis sp. nov.) new for science. The new species differs from the most similar species of the genus Doryphoribius mainly by different configuration of gibbosities on dorsal side of the body (configuration 4, 4, 4, 4, 4, 4, 4, 2, 2 in the new species; 2, 2, 2, 2, 2, 2, 2 in D. dupliglobulatus; 4, 4, 4, 4, 4, 4, 4, 2, 2, 3 in D. gibber; 6, 4, 6, 4, 6,4, 4, 2 in D. zyxiglobus).

This paper deals with specimens of Cirrophorus collected from the depths ranging from 3 to 500 m in 2012 and 2013 in the Sea of Marmara, Turkey. Among the material, one new species and two already known species were found. The new species is mainly characterized by having long and clavate notopodial postchaetal lobes in the branchial region; red speckles near nuchal organs; and a very long branch of lyrate chaetae (4 times longer than the shorter one). A recently described species, Cirrophorus nikebianchii, was found at the majority of soft-bottom stations. All species found in the area were described and discussed.

In this paper we describe a new genus and a new species of Chiridotidae based on specimens collected in shallow water off the South-eastern Brazilian coast. Gymnopipina ikamiaba gen. nov. et sp. nov. is characterized by the complete absence of dermal ossicles in the body, and it differs from the other ossicleless apodids in the number of tentacles and of Polian vesicles, and in the morphology of the calcareous ring. Although not formally tested with a phylogenetic framework, apodids have apparently lost their dermal ossicles multiple times. If these reversions hold true, Gymnopipina gen. nov. represents the fourth independent loss of dermal ossicles in the class Holothuroidea. An identification key to the Brazilian apodid species is also provided.

Minibiotus gumersindoi n. sp. is described. This species was collected on a granite mountain range in Sierra de Guadarrama (Bustarviejo valley, Embalse de la Jarosa and Cercedilla, Madrid, Spain) and on a volcanic island in Parque Natural Caldera de Taburiente (La Palma, Canary Islands, Spain). This new species is characterized by a unique set of characters in the genus: the presence of large round pores in the body and a larger round pore at the distal part of each leg. New records of several known species, for Madrid, Canary Islands and/or the Iberian Peninsula are given.

A New Species

During ArcticNet surveys aboard ‘CCGS Amundsen’ in 2011, several subtidal stations located in Canadian Archipelago were sampled in order to study the composition of their benthic communities. Among the abundant material sampled, several specimens of rare polychaete species were found. Examination of this material showed four species not previously recorded in the area, and a new species described herein. Descriptions of these specimens are given in this work.Ophelina brattegardiKongsrudet al., 2011 is characterized by a body composed of 27–28 chaetigers, by having the parapodia of the last four chaetigers shifted to the ventral side of the body, and by lacking branchiae in mid-body chaetigers.Macrochaeta polyonix Eliason, 1962 is unique within the genus in having several (instead of one or two) compound neurochaetae in anterior parapodia.Chaetozone acutaBanse & Hobson, 1968 is characterized by having spines from anterior third of the body and arranged in bundles composed of just a few chaetae.Chaetozone jubataChambers & Woodham, 2003 can be distinguished from similar species by having very long capillary chaetae from chaetiger 2 or 3. Finally,Dialychone hervyaen. sp. is characterized by bearing four pairs of radioles with narrow flanges, by the bilobed tip of its first peristomial ring that projects beyond the collar, and by the paleate thoracic notochaetae bearing long mucros.

A New Species

We describe a new species of the genus Rhinodrilus from the transition between the Amazon, Cerrado and Caatinga biomes in the State of Maranhão, Brazil. The region is currently being converted to large-scale agriculture, which may cause severe losses in the local fauna and flora diversity yet very poorly studied. Rhinodrilus antonioi sp. nov. has irregular setae in the posterior region of the body, spermathecae without diverticula, tubercula pubertatis in the form of band extended in the line BC in XXI–XXV and clitellum from XIV–XXVII. Five new records are reported for the region, Dichogaster bolaui, Liodrilus mendesi, Pontoscolex (Pontoscolex) corethrurus, Urobenus brasiliensis and Urobenus petrerei.

A New Species

A new species of Amanita sect. Roanokenses, A. brunneofolia, from South Korea, is described based on morphological and molecular evidences. The species is characterized by medium- to large-sized basidiomata, a greenish white pileus covered with brownish, floccose pyramidal volval remnants, an appendiculate margin, reddish brown lamellae, a long radicating stipe, and ellipsoid to elongate amyloid basidiospores. Based on both nrLSU and combined dataset (nrLSU, rpb2 and tef1-α), A. brunneofolia formed a monophyletic clade and clearly separated from other Amanita species. In addition, we describe two other Amanita species in A. sect. Roanokenses, namely, A. caojizong and A. sphaerobulbosa. This is the first report of these species for South Korea.

A new species of amphipod, Bathyporeia watkini sp. nov. from the Atlantic coasts of North Africa is described. This very characteristic species is abundant in some lagoons and estuaries near 28°N. New morphological information on B. elkaimi d’Udekem d’Acoz and Menioui, 2004 is given after specimens that were recently collected on the Atlantic coasts of southern Spain and South Portugal. The male of B. ledoyeri d’Udekem d’Acoz and Menioui, 2004 is described for the first time and new records of North African B. guilliamsoniana (Bate, 1857) and B. chevreuxi d'Udekem d'Acoz and Vader, 2005a are discussed.
