Trichomycterus rubbioli, herein described, is a new species from the limestone caves of the Água Clara system from theSerra do Ramalho karstic area, southwest of Bahia State, north-eastern Brazil. The new species is diagnosed by the com-bination of the following non-exclusive characters: highly reduced skin pigmentation; reduced eyes, externally visible assmall black or reddish-brown spots; long barbels, especially the nasal (86.9–127.1% of head length) and maxillary (98.1–129.3% of head length); and pectoral-fin ray count reaching I, 9. The troglobitic status is suggested by the presence oftroglomorphisms on an advanced degree, especially the reduction of skin pigmentation and the regression of the eyes, be-sides the absence of individuals in superficial drainages of the region. Population densities, recorded on two occasions,were extremely low. Trichomycterus rubbioli occurs in water bodies formed by infiltration in the rock, and, because of this, it must be considered fragile and as a priority in conservation programs of Brazilian karstic areas.

Utricularia biceps (Lentibulariaceae), a new species belonging to U. sect. Foliosa, is here described and illustrated. This new species is endemic to the campos rupestres of eastern Brazil, an extremely biodiverse and endangered vegetation. Notes on phenology, ecology, habitat, and conservation are provided, along with a discussion on the features that distinguish this species from the other taxa of the genus. The recent discovery of this and many other new species in the Botumirim region, in northern Minas Gerais, highlight this area as a priority for biodiversity conservation and emphasize the importance of extensive studies on the flora of the region.

A new species of characid, Hyphessobrycon vinaceus, is described from the upper rio Pardo, Minas Gerais, Brazil. The new species is distinguished from all other Hyphessobrycon species by the combination of the following characters: the body red or reddish pigmented in live specimens, an anterior and conspicuous vertically elongate black humeral spot followed by a second faint humeral spot, 5 teeth in the inner series of premaxilla, maxilla with 2-3 pentacuspidate teeth, 15-17 branched anal-fin rays, 4-5 scale rows above and 3-4 scale rows below lateral line, lateral line with 10-26 perforated scales, 32-34 scales in a longitudinal series, and by a smaller head length in relation to standard length (23.9-26.7%).

Parotocinclus arandai, new species of the hypoptopomatine catfish, is described from small creeks in the upper rios Jucuruçu and Buranhém basins, at the border of Brazilian States of Bahia and Minas Gerais. Parotocinclus arandai is distinguished from all congeners from the Atlantic coastal basins of southeastern and eastern Brazil, except Parotocinclus bahiensis, by having the branched rays and interradial membranes of the pectoral and pelvic fins unpigmented in ventral view. The new species is distinguished from most Parotocinclus species, by having a small eye, 14.8-19.3 mm HL (except P. maculicauda and P. planicauda) and by the presence of a tuft of hypertrophied odontodes on the supraoccipital (except P. cristatus and P. cesarpintoi). Parotocinclus arandai is further distinguished by having an abdomen extensively naked, with a mosaic of few rounded platelets of irregular size and distributed over the pre-anal region (except P. bahiensis, P. minutus, P. spilosoma, P. cearensis, P. cesarpintoi and P. prata). A detailed comparison with congeners on eastern Brazil hydrographical region is provided, and information on the species habitat is given.

Specimens found between 1985 and 1988 in the Magé River Basin, south-eastern Brazil were misidentified as L.splendens. The recent rediscovery of other specimens in the Estrela River Basin near the type locality of L.splendens has clarified the species’ concept, making it possible to recognise the Magé River Basin specimens as a new species. The new species is herein described as Leptopanchaxsanguineussp. nov. and is distinguished from all other cynopoecilines by a unique colour pattern in males, including red bars with sinuous margins. It was collected in a well-preserved, temporary shallow swampy area within dense moist forest, but since 1990 the species has not been found again. Leptopanchaxsanguineussp. nov. is one of three species of cynopoeciline killifishes living in lowland moist forests of the coastal plains of Rio de Janeiro State, where the greatest diversity of endemic cynopoecilines is concentrated. Each of these species has been recorded a single time in the last 30 years, a surprisingly low record attributable to intense deforestation during the last several decades resulting in small fragmented lowland moist forests of today. This study indicates that seasonal killifishes adapted to uniquely live in this kind of habitat should be regarded with special concern in studies evaluating conservation priorities.

ABSTRACT A new species of the loricariid genus Pareiorhaphis is described based on specimens from several tributaries of the upper and middle rio Jequitinhonha basin, Minas Gerais State, eastern Brazil. The new species increases the number of known species of Pareiorhaphis to 25 and, at the same time, represents the second member of the subfamily Neoplecostominae reported from the rio Jequitinhonha basin. The new species is diagnosed from all remaining congeners by a putative autapomorphic feature related to the color pattern: a well-defined, dark brown stripe on the median series of lateral plates that extends along the flank from the posterior margin of compound pterotic to the caudal-fin base. The shallow caudal peduncle and the comparatively larger number of dentary teeth also distinguish the new species from most congeners. The new species is also compared to Pareiorhaphis stephanus, a syntopic congener with similar traits.

We describe a new species of spinySolanum(Solanumsubg.Leptostemonum), endemic to the Brazilian Atlantic Forest and associated with granitic outcrops (inselbergs or sugar loaf mountains).SolanumkollastrumGouvêa & Giacomin,sp. nov.is morphologically similar to the poorly knownS.sublentumHiern, but is a heavily armed, much more robust plant with stellate-glandular indumentum. Together withS.sublentum, it is morphologically related to some species ofSolanumsuch asS.hexandrumVell.,S.robustumH.Wendl., andS.stagnaleMoric. that share strongly accrescent calyces, large leaves with the bases decurrent on to the petiole, pendent simple inflorescences and large, robust flowers. The new species is restricted to a few known populations in southern Bahia and north-eastern Minas Gerais states and conservation efforts are needed.
