Fruit Size And Shape

A new South American species of Salacia (Celastraceae, Salacioideae) found in Colombia and Venezuela, Salacia fugax Lombardi & M.Serna is described here. It is characterized by its indument, small long acuminate leaves with short petioles, branched inflorescences, flowers with an annular-pulvinate disk, and small pyriform fruits. This new species resembles S. mennegana J.Hedin ex Lombardi and S. opacifolia (J.F.Macbr.) A.C.Sm. by its short petioles, leaf shape, slender branched inflorescence, perianth form, and similar disc, but S. fugax differs by its hairs, leaf size and apex, calyx, and fruit size and shape.

Gardenia reflexisepala (Rubiaceae) is described from Hainan Province, China based on distinctive morphological characters of the calyx. This new taxon was previously confused with G. angkorensis, an Indo-Chinese taxon to which it is superficially similar based on leaf size, seed size and shape, fruit size and shape and branching architecture. Gardenia reflexisepala differs from G. angkorensis in having linear and strongly reflexed calyx lobes, glabrous outer surface of the calyx tubes and glabrous petioles. Lectoypification of G. angkorensis and G. cambodiana is also made here.

Two New Species

During the analysis of European and American herbaria collections for a taxonomic review of the Brazilian species of Gurania, two new South American species were found.  Gurania jeffreyi occurs in Ecuador and Colombia and Gurania calathina is found only in Colombia. Descriptions and illustrations of the new species are presented with comments on affinities and differences between them and related species.

Species Diagnosis

The genus Centris Fabricius, 1804 is one of the more diverse lineages of solitary bees in the Neotropical Region with more than250 described species. Here Centris ceratops new species is described from a tropical dry forest in northern Colombia (Colosó,Department of Sucre), thus increasing the number of known species to four in which the females possess a horn-like projectionon the clypeus. This group of bees belongs to a small monophyletic group within C. (Heterocentris). Along with the description of this new species, diagnosis, pictures and a key to identify the species of females with modified clypeus are also provided.

A New Species

A new South American genus of Delphacini (Hemiptera: Fulgoromorpha: Delphacidae), Neodelphax n. gen., is described. It includes a new species, N. sakakibarai sp. n., which is described herein, and two species that are removed from the genus Dicranotropis. All of them are illustrated. Supplementary descriptions of female N. fuscoterminata (Berg) comb. n. and N. acheron (Fennah) comb. n., including some new records and host plant associations are added. A preliminary key for males and females of South American species of Neodelphax with representative illustrations is also provided.

Biogeographic Analysis

The mite order Opilioacarida is widely distributed in the tropical and sub-tropical zones of the world, where it is rare and poorly known. On the American continent only two genera, 14 species and one subspecies are known. This work aimed to describe a new species of Caribeacarus from the state of Pará, in the eastern part of the Brazilian Amazon. A phylogenetic analysis of the species in this genus is also presented, and interpreted along with the historical biogeography of this genus in Central and South America. A key to the species of Caribeacarus is provided.

First Time

Crossopalpus is a rather diverse genus of tachydromiine flies, but regionally the genus is nowhere very speciose. Knowledge on the South American Crossopalpus before this paper included two described species from Andean related habitats, with several biomes from the eastern part of the continent being completely unexplored. Herein, we describe four new species of Crossopalpus from eastern South America, namely: C. albivertex sp. nov., C. aliceae sp. nov., C. goliathus sp. nov., and C. xanthogaster sp. nov. New diagnoses and high quality photographs are made available for C. armipes (Bezzi, 1909) and C. pennescens (Melander, 1918), including some characters used for the first time to distinguish South American species. We provide a key for identification of the six South American species, discussion about the position of Crossopalpus in Drapetidini, and some biogeographical insights including preferred habitats and seasonality of the South American species. We discuss the apparent loss of tergite 10 in females of Drapetidini, introducing a reinterpretation where the sclerite may be present in some genera of the tribe, but fused to the cerci and/or sternite 10.

The new species occur in the Brazilian Atlantic Forest (M. costeira and M. subterminalis), the Espinhaço range in Brazil (M. ascendens and M. rupestris) and the eastern Guiana Shield in French Guiana (M. attenuata).

A New Species

Pseudognaphalium is a large genus with about 90 species distributed worldwide, but with most species in America, and some in Asia, and Africa. A new species, P. munoziae, from the north of Chile (Parinacota and Iquique provinces), is described and illustrated. Pseudognaphalium munoziae is similar to P. glandulosum but it is principally distinguished by its rosulate basal leaves which are longer than the upper, all of which are apically acute to subobtuse. A key to the species of dwarf Pseudognaphalium occurring in Chile is provided along with a map of their distribution.
