A New Species

A new species of the genus Cyphocaris Boeck, 1871, is described. The material examined was collected during the “Acoustics along the Brazilian Coast” (Abraços 1) project, by micronektonic trawls at a targeted depth of 525 m, off the Rocas Atoll, Rio Grande do Norte state, Brazil. Cyphocaris boecki sp. nov. can be grouped with the eyed species in the genus but differs from them—except for C. faurei K. H. Barnard, 1916 and C. latirama, Hendrycks & Conlan, 2003—in presenting a dorsally smooth pereonite 1. However, the new species can be distinguished from both by its maxilliped inner plate with two robust apical setae, pereopod 7 basis with weakly produced posterodistal lobe, telson lobes without setae, spines or apical nails, and other characters that are individually discussed among them. The new species can be readily differentiated from C. pedroi Sorrentino, Alves, Johnsson & Senna, 2016, also described from Brazil, by presenting eyes, a rounded lateral cephalic lobe, very elongated antenna 2 almost reaching body length, and pereopod 5 basis, with apically acute spur reaching about two-thirds of the propodus. This is the second record of the genus for Brazilian waters.

A New Species

Sponges of the Family Pachastrellidae Carter, 1875 are distributed worldwide and found generally in deep water. Up to date, only four species are known for the Brazilian coast (Muricy 2018): Characella aspera Sollas, 1886, C. capitolii Mothes et al. 2007, C. pachastrelloides (Carter, 1876), and Pachastrella monilifera Schmidt, 1868. In this study, a new species of Characella is described from the mesophotic zone off Bacia Potiguar (Rio Grande do Norte State, Northeastern Brazil). The specimen was preserved in 80% ethanol and deposited in the Porifera Collection of the Universidade Federal de Pernambuco (UFPEPOR). Taxonomic comparisons were made with data tabulated for all species of Characella available in the World Porifera Database (van Soest et al. 2018).

A New Species

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.

A New Species

A new species of freshwater crab, Fredius ibiapaba, is described and illustrated from a mid-altitude forested patch in Ipú (Ibiapaba plateau, Ceará, northeastern Brazil), between 635 to 782 m. The new species can be separated from its congeners by the morphology of its first gonopod: proximal half remarkably swollen, sloping abruptly downwards distally to a nearly right-angular shoulder; mesial lobe much smaller than cephalic spine; cephalic lobe moderately developed; auxiliary lobe lip, delimiting field of apical spines, protruded all the way to distal margin of auxiliary lobe. Comparative 16S rDNA sequencing used to infer the phylogenetic placement of Fredius ibiapaba n. sp. revealed that it is the sister taxon of F. reflexifrons, a species which occurs allopatrically in the Amazon and Atlantic basin’s lowlands (<100 m). Fredius ibiapaba n. sp. and F. reflexifrons are highly dependent upon humidity and most probably were once part of an ancestral population living in a wide humid territory. Shrinking humid forests during several dry periods of the Tertiary and Quaternary likely have resulted in the fragmentation of the ancestral humid area and hence of the ancestral crab population. Fredius reflexifrons evolved and spread in a lowland, humid river basin (Amazon and Atlantic basins), whilst F. ibiapaba n. sp. evolved isolated on the top of a humid plateau. The two species are now separated by a vast intervening area occupied by the semiarid Caatinga

A New Species

A new species of Smicridea (Smicridea) McLachlan 1871 is described and illustrated based on specimens collected from the Caatinga biome, in Sete Cidades National Park, Piauí state, and Ubajara National Park, Ceará state, northeastern Brazil. Based on phallus morphology, Smicridea (Smicridea) caatinga sp. nov. belongs to the S. nigripennis Group and can be distinguished from other species in this group due to the phallus having two ventral sclerotized projections and, when expanded, two dorsal membranous lobes and one ventrolateral membranous lobe with two spines on the apex. New distributional records of Smicridea species are provided for different Brazilian states: S. (S.) aequalis Banks 1920 for Ceará and Piauí, S. (Rhyacophylax) coronata Flint 1980 for Rio Grande do Sul and Piauí; S. (R.) jundiai Almeida & Flint 2002 for Mato Grosso; S. (R.) marlieri Flint 1978 for Roraima; S. (R.) palmar Sganga 2005 for Goiás; S. (S.) paranensis Flint 1983 for Ceará and Piauí; and S. (R.) spinulosa Flint 1972 for Rio Grande do Sul. Furthermore, S. (S.) erecta Flint 1974b is recorded for the first time for Brazil, in Amazonas state. [Zoobank: urn:lsid:zoobank.org:act:3C2892F9-D430-492B-98DA-A48569253A63]

A New Species

The family Nannosquillidae contains thirteen genera, one of which is Nannosquilla, composed of twenty-five species. The genus is distributed on both sides of the American continent, but contains no amphi-American species, and only one species in Indonesia. During surveys conducted in the Potiguar Basin, Rio Grande do Norte state/BR, a new species, Nannosquilla potiguara, was found. The new species is similar to N. schmitti, sharing the characters of seven intermediary fixed teeth in the posterior margin of telson on both side of the submedians movable tooth, and the inner spine on the uropodal protopod being longer than the outer. The two species differ in the number of teeth of the raptorial claw, in the morphology of rostral plate, and in the median projection of telson. From the Brazilian coast only one other species, N. dacostai, has previously been recorded. It is similar to new species in the subpentagonal rostral plate and the inner spine of uropodal protopod being longest, but N. potiguara n. sp. differ by a larger number of teeth on the dactylus of the raptorial claw and by fixed teeth on each side of the submedian movable teeth at telson. A key to the Atlantic species of Nannosquilla is given.

A New Species

Serrapinnus potiguar, new species, is described from the rio Ceará-Mirim, a coastal drainage in the Rio Grande do Norte State, northeastern Brazil. The new species is distinguished from the other species of the genus by the shape and arrangement of the ventral procurrent caudal-fin rays of the sexually dimorphic males; where the hypertrophied elements present the shape of a series of scimitars arranged radially, forming a semi-circle on the ventral margin of the caudal peduncle. Furthermore, the new species is diagnosed from S. heterodonand S. piaba, sympatric congeners from the northeastern Brazilian drainages, respectively by the presence of incomplete lateral line and teeth bearing at most five cusps.

A New Species

Trichoptera is the largest order of exclusively aquatic insects, comprising more than 16,000 described species with cosmopolitan distribution. There are about 800 species recorded from Brazil so far, mostly from the North, Southeast, and South regions. In Northeastern Brazil, the state of Rio Grande do Norte has only one Trichoptera species recorded so far (Oecetis excisa). Here, Chimarra (Chimarra) potiguar n. sp. is described and illustrated. The new species can be easily distinguished from its congeners by the following features: Segment X has its mesal lobe elongate, sub-rectangular; lateral lobes long and rounded apically, dorsal margin with subapical invagination; the apex of each inferior appendage has a pronounced apicodorsal acute projection, and the phallotremal sclerite complex is curved, with small spines dorsally. Chimarra (C.) potiguar is morphologically similar to Chimarra (Chimarra) bidens, but the new species differs from it by the length and shape of the mesal lobe and lateral lobes of segment X, and by general shape of the basal regions of inferior appendages. Five additional caddisfly species are recorded for the first time from Rio Grande do Norte state: three in Hydropsychidae (Leptonema sparsum, Macrostemum hyalinum, and Smicridea (Smicridea) palifera) and two in Polycentropodidae (Cyrnellus fraternus and Cernotina bibrachiata).
