Abstract—We present a new species, Turnera fasciculifolia, from the Jalapão region, the largest continuous protected area of Cerrado in Tocantins State, in central Brazil. The new species belongs to Turnera series Leiocarpae, and it can be recognized by the linear ericoid leaves with revolute margin, generally without extrafloral nectaries, and the basal leaves of the young axillary branches gathered in fascicles. We provide a description, illustrations, a distribution map, and a comparison with T. genistoides and T. revoluta, which also have ericoid leaves.

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.

Sonerila cardamomensis, a new species of family Melastomataceae from the Central Cardamom Protected Area in Koh Kong province of southwestern Cambodia, is described and illustrated. The species is similar to S. violifolia Hook.f. ex Triana, but is readily distinguished by its cordate leaf base, lack of setae at the nodes, longer pedicels, smaller petals, smaller hypanthiums and smaller capsules.

A species of the skink genus Lerista is described from Cape York Peninsula in Queensland.  The species is biogeographically interesting as it appears to be separated by at least 500 km from its nearest relatives, members of the Lerista allanae clade.  The role of Pleistocene sea level changes altering availability of suitable habitat for these sand specialists is discussed as a possible driver of isolation and speciation.

A new species, Stenomorpha roosevelti Smith, Miller, and Wheeler, n. sp., is described from the Cuatrociénegas Protected Area in Coahuila, Mexico. Three related species are transferred into Stenomorpha, producing the following new combi- nations: Stenomorpha furcata (Champion), Stenomorpha wickhami (Horn), and Stenomorpha granicollis (Blaisdell). A new informal group, the furcata species group, comprised of these four species is recognized within Stenomorpha. Diagnoses of the group and its species are provided, along with distribution data and a key to the species.

Curupirina papuana sp. n. and an unnamed species of a probably new genus of Apistomyiini (Diptera : Blephariceridae) are described from the Ok Tedi, a tributary of the Fly River, Papua New Guinea. This is the first report of the family from the island; its zoogeographical significance is discussed with reference to the long-presumed role of the island in the evolution and dispersal of the tribe Apistomyiini.

Werauhia maculata a new species from Tabasco, Mexico is described and illustrated. The new taxon possesses a large tank-rosette, with conspicuous and irregularly disposed dark purple marks on the basal portion of the leaves abaxial surface, a simple inflorescence, with secund and numerous whitish-flowers densely arranged on the rachis. The new taxon is compared with W. pectinata and W. noctiflorens, species with similar characteristics. In addition, some data about its reproductive biology are presented.
