A New Species

A new species of Inga (Leguminosae, Caesalpinioideae, Mimosoid clade), restricted to the Atlantic Forest of Minas Gerais State, Brazil, is described, illustrated, and compared in an inedited identification key to the species with stipitate extrafloral nectaries in the biome, Inga ciatiformis is similar to Inga cabelo and Inga platyptera. It differs from I. cabelo by having appressed-sericeous young branches, leaves with 1–3 pairs of leaflets, a terminal appendix 7–12 mm long, cyathiform extrafloral nectaries, bracts 9–13 mm long, linear, persistent, and a sparsely sericeous calyx (vs. hirsute-hispid young branches, leaves with 2–5 leaflets pairs, terminal appendix 2.5 mm long, capitate extrafloral nectaries, bracts 2 mm long, triangular, caducous, and a hirsute calyx). It differs from I. platyptera by having appressed-sericeous young branches, a cylindrical petiole and rachis, rachis rarely winged in the superior portion of the apical pair of leaflets, extrafloral nectaries always cyathiform, and linear bracts (vs. hispid young branches, winged petioles and rachises, extrafloral nectaries generally cupuliform, and lanceolate to ovate bracts).

A New Species

We described a new species of Phyllanthus currently known from a single fragment of Ombrophilous Dense Forest in the Jequitinhonha Valley, Minas Gerais State, Brazil. Phyllanthus pedicellatus is the second species of the genus with phylloclades found in the Atlantic Forest domain, once mostly Brazilian Phyllanthus with these kinds of specialized branches grow in open vegetation as “campos rupestres” and cerrado. The name is a reference to its remarkable pedicels of pistillate flowers. We present illustrations and photographs of the new species in its habitat, comments on its relationships to other Brazilian Phyllanthus, and its conservation status.

Paepalanthus mellosilvae is here described and illustrated as a new species of Eriocaulaceae from the Atlantic Forest domain in Minas Gerais state, Brazil. The new species is known from a single locality in the Mantiqueira Range, growing along trails through cloud forests. According to the IUCN criteria, it is suggested here as critically endangered. Paepalanthus mellosilvae is compared to P. harmsii, a morphologically similar species also growing in the Mantiqueira Range, being mainly distinguished by the presence of a rhizome, narrower leaves, more numerous scapes, narrower capitula, sparsely pilose involucral bracts, and obdeltate floral bracts. Additional comments on the taxonomy, morphology, and distribution of the species, along with illustrations are provided. The specific epithet is a tribute to Prof. Dr. Renato de Mello-Silva.

A New Species

Colanthelia is a woody bamboo genus belonging to the Arthrostylidiinae and currently includes nine species. It can be recognized by a suite of morphological characters including hollow and thick-walled culms, branch complement with a promontory in the base and a dominant divergent branch bearing few to many secondary small branchlets from its base, culm leaves with a relatively well developed girdle and a crest or skirt at the juncture of the sheath and girdle, racemose or weakly paniculate synflorescences, and relatively long and narrow spikelets with visible rachilla internodes. During recent fieldwork in Minas Gerais state, a new species, Colanthelia longipetiolata, from the Brazilian Atlantic forest was collected, which is here described and illustrated. So far as we know, the species is endemic to the Caparaó National Park, in Minas Gerais state. Comments on its habitat, distribution and conservation status, a morphological comparison between C. longipetiolata and C. sparsiflora, and a revised identification key to all species of the genus are provided.

A New Species

During a floristic study of Chamaecrista in Diamantina plateau, Minas Gerais state, a new species was discovered. Chamaecrista petiolata is here described, illustrated, and compared to its putative closest relative species, C. catapodia and C. monticola. These species are shrubs, the stem-axis exceeding 1.5 m, and show sessile leaves, whereas C. petiolata is a subshrub up to 40 cm alt., with short petiolate leaves. The new species belongs to subsection Absus, which is characterized by glandular trichomes and lack of extrafloral nectaries.

Microvelia joceliae Magalhães & Moreira, sp. nov. is described and illustrated based on material from Parque Natural Municipal das Andorinhas, Minas Gerais State, in southeastern Brazil. The new species can be distinguished from congeners occurring in the region by the pronotum of the apterous form covering almost the entire thorax dorsally, proepisternum with black denticles, male abdominal segments V–VII ventrally depressed, shape of the asymmetrical parameres, and female abdominal laterotergites reflected over the mediotergites and almost touching over segments V–VII.

Abstract A new species of harpacticoid copepod, genus Forficatocaris (F. odeteae n. sp.) is described from a high-altitude pond at the Itacolomi National Park near Ouro Preto city, Minas Gerais state, Brazil. The main characters distinguishing the new species from F. affinis Dussart, 1983 and F. lilianae Noodt, 1972 are: (i) distal portion of exopod 1 of male leg 4 with stout spinules; (ii) male leg 5 lateral spine stout and with blunt apex; (iii) endopod of leg 4 curved outwards, but “c” shaped (not forming a straight angle); (iv) female with dorsal spinule row on anal somite larger than in congeners, ventral ornaments smaller and less numerous; and (v) the shape of the modified spine located at the leg 1 endopod 1 of the male; and (vi) the spine of leg 5 in males and females.
