New records and bathymetric distribution of deep-sea shrimps of the family Glyphocrangonidae (Decapoda: Caridea) from the Potiguar Basin, northeastern Brazil

Heterocarpus inopinatus is a member of the family Pandalidae. It is an endemic species from Brazilian’ waters which is recorded for states of Bahia, Espírito Santo and Rio de Janeiro. In this paper, we report the occurrence of this species from extreme northeast of Brazil in Potiguar Basin. The Potiguar Basin is situated in the extreme northeast of Brazil, between the states of Ceará (CE) and Rio Grande do Norte (RN) (03/05° S; 38/35° W). Samplings were conducted as part of the project: "Avaliação da Biota Bentônica e Planctônica da Bacia Potiguar e Ceará (Bpot)” sponsored by “Petróleo Brasileiro S/A (Petrobrás)”. In the campaign were analyzed 19 individuals, being 10 females, 8 males and 1 juvenile, between the depths of 150–982 m. Therefore, this study is increasing its geographic distribution and thus much extending its bathymetric distribution of the species to shallower depth for the Northeast region of Brazil, filling gaps in the South Atlantic distribution.

This paper reports the occurrence of four deep waters shrimps of the family Solenoceridae in the southwestern Atlantic, Brazil. The rare Hadropenaeus modestus is collected for the second time from Brazilian waters after 138 years, filling the gaps on its distributional pattern. Mesopenaeus tropicalis is a new register for Potiguar basin, although it is common along Brazilian coast. Hymenopenaeus chacei and H. laevis are recorded for the first time in southwestern Atlantic. The records of these species in the southwestern Atlantic are an important advancement to raise the knowledge of the deep-sea shrimps.

The World

The family Hormathiidae Carlgren, 1932 is one of the largest families of sea anemones with ca. 130 species around the world, mostly in the deep sea. In Brazilian waters, only six species have been reported so far. Herein we record four hormathiids from deep-sea sites at the Potiguar Basin continental slope at Northeast Brazil. Monactis vestita (Gravier, 1918) and Phelliactis robusta Carlgren, 1928 represent the first records of both genera for the Brazilian coast. The new species Paraphelliactis labiata n. sp. is described. We also found another species of the genus, Phelliactis sp. The new species possesses fourth and fifth cycles of incomplete mesenteries, unlike all other Paraphelliactis species. These results increase the total number of hormathiid sea anemones in Brazil to nine and contribute to the knowledge of the Brazilian deep sea, still little explored.

Larvae and juvenile of Synchiropus atrilabiatus (Garman 1899), expands its distribution range within this coast (between Tumaco in the South to the border with Panama in the North), presenting low to medium abundances in September-October 2002, 2003, 2004, 2005 and February-March 2006, 2014. Larvae were always collected at stations 54 km away from the coast. Adults of S. atrilabiatus were collected as bycatch from the deep-sea shrimp fishing fleet between 67-700 m depth at Bahía Cupica in 1995 and Arusí in 2005.

First Time

Thirty-six species of various thecate hydroids occur in two recent, deep-water collections from off New Caledonia. Of these, nine are new, namely Solenoscyphus subtilis Galea, sp. nov., Hincksella immersa Galea, sp. nov., Synthecium rectangulatum Galea, sp. nov., Diphasia alternata Galea, sp. nov., Dynamena opposita Galea, sp. nov., Hydrallmania clavaformis Galea, sp. nov., Symplectoscyphus acutustriatus Galea, sp. nov., Symplectoscyphus elongatulus Galea, sp. nov. and Zygophylax niger Galea, sp. nov. The male and female gonothecae of Caledoniana decussata Galea, 2015, the female gonothecae of Caledoniana microgona Galea, 2015, as well as the gonothecae of both sexes of Solenoscyphus striatus Galea, 2015 are described for the first time. The systematic position of the genera Solenoscyphus Galea, 2015 and Caledoniana Galea, 2015 is discussed on both morphological and molecular grounds, and both are confidently placed within the family Staurothecidae Maronna et al., 2016. In light of the molecular data, the genera Billardia Totton, 1930 and Dictyocladium Allman, 1888 are assigned to the families Syntheciidae Marktanner-Turneretscher, 1890 and Symplectoscyphidae Maronna et al. , 2016, respectively. The previously undescribed gonothecae of Hincksella neocaledonica Galea, 2015, and the male gonothecae of Sertularella tronconica Galea, 2016, were found. Thyroscyphus scorpioides Vervoort, 1993, a peculiar hydroid with putative stem nematothecae, is redescribed and assigned to the new genus Tuberocaulus Galea, gen. nov. Noteworthy new records from the study area are: Tasmanaria edentula (Bale, 1924), Hincksella sibogae Billard, 1918, Dictyocladium reticulatum (Kirchenpauer, 1884), Salacia sinuosa (Bale, 1888) and Billardia hyalina Vervoort & Watson, 2003. Most species are illustrated to facilitate their identification, and the morphology of the new ones is compared to that of their related congeners.

A New Species

Sediment samples were collected from the deep sea adjacent to the State of Sergipe (Northeastern Brazil) within the framework of the Sergipe Continental Slope Environmental Characterization Project (coordinated by PETROBRAS, the Brazilian Petroleum Company S/A). These revealed a new species of the family Paramesochridae (Copepoda, Harpacticoida). Kliopsyllus minor sp. nov. is the smallest species discovered in this genus, with a body length of 0.19 mm in the adult male. Furthermore, it is one of the three Kliopsyllus species registered from the deep sea so far. In almost all Kliopsyllus species, the endopod of P4 is one-segmented. Only three species, i.e. Kliopsyllus andeep Veit-Köhler, 2004 from the abyssal Weddell Sea, a new species by Veit-Köhler and Thistle from the San Diego Trough (deep Pacific Ocean) and the new species presented here, show a two-segmented endopod in the P4. Kliopsyllus andeep is distinguished by the presence of strong, chitinous processes at the telson, and additional setae at the endopods of P3 and P4. The new Pacific species and the new species from Brazil can be distinguished by the shape of the segments of the swimming legs and detailed characteristics of their setae and spines.

Relatively few calcareous sponges (Porifera, Calcarea) have been recorded from Brazil, mostly due to a reduced number of studies focused exclusively on these generally small, cryptic organisms. To fill in part this gap, the taxonomy and distribution of calcareous sponges from Potiguar Basin (Rio Grande do Norte state, Northeastern Brazil) are studied here. Thirty one specimens were collected by dredging, trawling and SCUBA diving from 2003 to 2007 from depths of 2 to 160 m. Seven species were found and are described here. Two of these species are new to science (Leucetta potiguar sp. nov. and Paraleucilla sphaerica sp. nov.), and four are new records for Rio Grande do Norte state (Clathrina aurea, Leucascus roseus, Leucetta floridana, and Leucandra serrata). An identification key for the species of Calcarea from Potiguar Basin is provided here.

The Family

Species of ophiuroids in Brazilian waters were last compiled over a decade ago. Since that time, there have been manyimportant contributions with additional diversity and species distribution data. An updated review of the number of records isnecessary, as well as an identification of the gaps related to the taxonomy. We list a total of 133 species that belong to 54genera and 16 families. This number corresponds to approximately 6% of the species described worldwide. All families havebeen registered, and the majority of species belongs to the family Amphiuridae (50spp), which have primarily been recoveredduring surveys of the shallow waters of the continental shelf. On the other hand, numerous new records (e.g. species belongingto the families Ophiacanthidae and Ophiuridae) have been registered in recent years from the deeper margins of Brazil. Asophiuroids are an abundant component of the benthic fauna, increasing occupation of coastal areas and the exploration of energy and mineral resources in the deep sea call for a better knowledge about the diversity and biogeography of the group.
