Three New Species

Three new species of Microlicia endemic to Serra do Cipó, Minas Gerais state, Brazil, are described here. Microlicia joaosemiriana and M. longiglandulosa are characterized by their sessile leaves, congested flowers at the apex of the branches, dimorphic stamens with tetrasporangiate and bicolorous anthers. However, M. joaosemiriana differs in having hypanthium and sepal covered only with spherical glands and sepal shorter than the hypanthium length. Microlicia longiglandulosa has hypanthium and sepal with glandular trichomes mixed with spherical glands and sepal longer than the hypanthium length. Microlicia jolyana has a petiolate and thickened leaf, lanceolate to oblong leaf blade, rounded to slightly acuminate at the apex, smooth and not striate hypanthium surface, triangular-oblong and thickened sepal, dimorphic stamens, and purple to purple-blackish anther on both whorls. Also, Microlicia linifolia var. naudiniana is elevated to species rank with a new name (Microlicia acerosa), and M. nortecipoana and M. petiolulata are synonymized under M. hirtoferruginea. Additionally, we provide an updated checklist of Microlicia species in the Serra do Cipó.

A New Species

Abstract—Fritzschia atropurpurea, an endemic new species from the Serra do Cipó, Espinhaço Range, Minas Gerais state, Brazil, is described and illustrated. This new species can be easily differentiated from its congeners by the combination of the following characters: hirsute-glandular trichomes covering the branches, petioles, leaves, bracteoles, pedicels, hypanthium, sepals, and the medial-apical portion of the right margin of the petals; membranaceous leaves with a dark purple abaxial surface; and long pedicels. Images from scanning electron microscopy, photos of the species in the field, a distribution map, and a key to identify the congeners that occur in the Serra do Cipó are presented. We suggest that if a formal assessment were performed, Fritzschia atropurpurea would probably be categorized as an Endangered (EN) species.

Cadeia Do Espinhaço

Three new species, of three different genera of loricariids, are described from the headwaters of Serra da Mantiqueira and Cadeia do Espinhaço, in Southeastern Minas Gerais State, Brazil. In this region, the Serra da Mantiqueira and the Complexo do Espinhaço are the highest points of the Brazilian Shield and delimits the headwaters of four drainages: São Francisco, Paraná, Doce and Paraíba do Sul basins. Harttia intermontana, n. sp., is described from the headwaters of the Rio Doce basin and is the first record of the genus in this basin. The new species can be distinguished from its congeners by the pattern of abdominal covering, presence of preanal plates, presence and pattern of ornamentation of canal plate, and some characteristics related to sexual dimorphism. Pareiorhaphis togoroi, n. sp., is described from the headwaters of the Rio das Mortes basin, tributary to the Rio Grande, in the upper Rio Paraná drainage, and represents the first record of the genus to this drainage, thus expanding its geographic distribution. It can be distinguished from most congeners by the absence of preadipose azygous plates, and characteristics related to secondary sexual characters of mature males: presence of odontodes on the lateral margin of head plus the absence of long hypertrophied odontodes on pectoral-fin spine. Neoplecostomus pirangaensis, n. sp., is described from the headwaters of the Rio Piranga, Rio Doce basin. The new species differs from all congeners by the much-reduced dermal platelets on the abdomen, devoid of developed odontodes between the insertions of the pectoral and pelvic fins. Neoplecostomus pirangaensis can also be distinguished from all congeners, except N. botucatu and N. paranensis, due to the complete absence of vestiges of the adipose fin (vs. vestiges, or adipose fin moderate to well developed and always present). The new species differs from N. botucatu by the absence of conspicuous dark spots all over the body and the presence of common dorsal bands in juveniles, and almost totally black in adults. It differs from N. paranensis by the bigger and less numerous teeth. Additionally, the new species differs from Neoplecostomus doceensis by the absence of enlarged fleshy folds between dentaries, and absence of a lateronasal plate.

Abstract—Three new species of Eriocaulaceae, endemic to the Serra da Canastra in Minas Gerais state, are described. Paepalanthus petraeus is assigned to P. ser. Paepalanthus, differing within the series by its thickened stem accumulating leaf sheaths, linear leaves, and numerous scapes shorter or equaling the leaf height and bearing capitula with brown involucral bracts. Paepalanthus sinuosus belongs to P. subsect. Polyactis and is distinguished by few scapes in lax fascicles, more than twice as long as the leaves, which are patent to slightly recurved, and light brown involucral bracts with acute apex. Syngonanthus culcitosus, within S. sect. Syngonanthus, is unique due to its elongate and branched stem forming dense mats, simple inflorescences, cream-colored involucral bracts equaling the length of the floral disc, and gynoecium with nectariferous appendages. Comparisons with the most similar species are provided for each new taxon. Maps, photographs, and illustrations are presented, together with comments on phenology, distribution, habitat, and morphology. Paepalanthus petraeus and P. sinuosus are likely to be assessed as Critically Endangered, and S. culcitosus as Vulnerable, according to IUCN criteria.

Abstract— Lychnocephalus cipoensis, L. grazielae, and L. jolyanus, three new species from the Cerrado of the Brazilian Central Plateau, are hereby described and illustrated. Lychnocephalus is characterized by its tomentose to densely lanate branches, heads organized in third order syncephalia and inner pappus series with twisted setae and narrowed apex. These new species are microendemic in the campos rupestres of Serra do Cipó, state of Minas Gerais, southeastern Brazil, and were previously misidentified as other species of the genus. However, they are distinguished by their habit, leaf arrangement, leaf shape and size, presence or absence of petiole, number of florets per head, and number of pappus series, among other characteristics discussed here. These new species are described and illustrated, their affinities discussed, and a key to all species of Lychnocephalus is provided.

A new species of Anthurium (A. mucuri E.G.Gonç. & L.F.A. de Paula) is described and illustrated. It occurs in rocky outcrops (inselbergs) in Minas Gerais state, Southeastern Brazil and it is so far know from a restricted area around the city of Teófilo Otoni. It seems to be closer to Anthurium viridispathum E.G.Gonç., but differs mainly in having smaller overall dimensions, a much narrower leaf blade and spathe and for the spathe that is glaucous in the inner surface. Anthurium mucuri is placed in the section Urospadix Engl. subsection Obscureviridia Engl.

Three new species of Pleroma are described: Pleroma costatocalyx, P. kollmanniana and P. subsessilis. All three species are morphologically similar to Tibouchina heteromalla and related species, especially due to the shrubby habit, elongated inflorescences, flowers with purple petals, but white at their bases, antesepalous stamens with the connective covered with glandular trichomes, and by the short (ca. 4–5 mm long), curved style. All three species differ from T. heteromalla by the styles with trichomes (vs. glabrous in T. heteromalla). Pleroma costatocalyx also differs from T. heteromalla by the longitudinally costate hypanthium, P. kollmanniana by the strongly winged branches, bigger leaves, and shorter petioles, and P. subsessilis by the concolorous leaves and antepetalous stamens with glabrous connective and appendages. All new species grow in vegetation associated with inselbergs and are endemic to Espírito Santo state, despite the fact that one of them (P. costatocalyx) was collected very close to the border with Minas Gerais, where it probably occurs. We present descriptions, taxonomic comments, illustrations, and conservation status assignments for the new species.
