Magnolia guerrerensis from the cloud forest in the state of Guerrero, Mexico, is illustrated and proposed as a new species. This taxon is similar to M. schiedeana Schltdl., but differs from it because of its smaller stipules, pedicellated flowers and gynoecium with less carpels. A key to distinguish both species is included.

A new species of Marsdenia (Apocynaceae; Asclepiadoideae) is described from the mountain cloud forest in the state of Guerrero, Mexico. Marsdenia microcarpa is distinguished from other species of the genus by its gynostegial corona lobes oblong-ovate, adnate to the gynostegium, free, erect or divergent obtuse apices, margins of lobes connate at base, corpuscle with rostrate apex, narrowly fusiform follicles of less than 5 cm at maturity. A key to the species of Marsdenia in the state of Guerrero is presented.

A new species of Vernonia (Asteraceae, Vernonieae) is described from mountain cloud forest, Pinus forest and Pinus–Quercus forest in the State of Oaxaca, Mexico. Typical characters of this species are the lax corymbiform inflorescences, formed by 3–10 heads on peduncles > 4.5 cm long, and the lanceolate or elliptic-ovate shape of leaves. A key to the Mexican species of Vernonia is included.

The new species Dicranocentrus paramoense, D. bidentatus, Heteromurus (Heteromurtrella) echinatus and H. (H.) pruinosus are described from specimens collected in the State of Mérida, Venezuela. A new species of each genus comes from a cloud forest near the city of Mérida and a new species of each taxon was collected in paramos northeast of Mérida. Congeneric species are phyletically very near and their closest relatives live in Central America and the West Indies. Dicranocentrus bidentatus is the sole species of its genus with only two teeth (the basal pair) along the inner margin of the unguis. Heteromurus (Heteromurtrella) echinatus is unique among members of its subgenus in possessing dental spines, although some individuals lack these structures. This is the first record of such intraspecific variation. Four tables detail variations of a number of characters and 41 figures complement the text.

We describe a new species of Pseudoeurycea from the cloud forests of Huatusco in the state of Veracruz, México. This species belongs to the P. cephalica complex. Pseudoeurycea cafetalera sp. nov. is sister to the clade formed by P. cephalica and P. quetzalanensis. The new species is diagnosed by a stout body, long stout legs, short digits, somewhat webbed hands and feet, a distinctive coloration and by divergent mitochondrial DNA sequences.

Pinguicula calderoniae is described as a new species to science. It grows on calcareous rocks in the cloud forest in the border of Querétaro and San Luis Potosí states. On account of its bilabiate corolla with long-infundibuliform tube, as long as or shorter than the spur, it is placed in subgenus Pinguicula, section Longitubus. This new taxon is clearly differentiated from other members of this group by its long lanceolatelinear summer leaves, which are unique in the section.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Only three species of Trichomyia Haliday have been recorded in Mexico. Trichomyia cirrata Coquillett, 1902, is recognized by its female characteristics, T. fairchildi Vargas and D az-N jera, 1953, was described based only on the wing and must be considered as species inquirenda, and T. maldonadoi (Vargas, 1953), which was described based on one female specimen. Specimens of Trichomyia collected in the states of Campeche, Yucatan, and Oaxaca, Mexico, allowed this female to be associated with the male of T. brevitarsa (Rapp, 1945), thus providing a first report of this species in Mexico. Consequently, T. maldonadoi is proposed as a synonym of T. brevitarsa. Additionally, a new species of Trichomyia from the state of Veracruz, Mexico, is described and illustrated based on the male and female characteristics.

We describe a new species of dull-colored flea-toad, genus Brachycephalus, from the Atlantic Forest of Caparaó mountains in southeastern Brazil. The new species is characterized by its diminutive size, “leptodactyliform” body, brownish color with an inverted V-shaped dark mark on dorsum, skin smooth, hyperossification and dorsal shield absent, linea masculinea absent, Fingers I and IV vestigial, Toe I externally absent, Toe II reduced but functional, Toes III and IV with pointed tips, Toe V vestigial, and ventral color uniformly brown. It is a leaf litter dweller, known only from type locality in the humid forests on the eastern slopes of Parque Nacional do Caparaó mountains, a protected area in the states of Espírito Santo and Minas Gerais, southeastern Brazil. It is the third flea-toad occurring in the state of Espírito Santo recovered as sister to all other Brachycephalus distributed from the state of São Paulo northward in the Atlantic Forest.
