A New Species

A new species of Genlisea section Genlisea from the white-sand savannas (“campinaranas”) of Brazilian Amazon is described and illustrated, providing remarks on habitat and ecology as well as SEM seed images. Genlisea multiflora has been recorded from Viruá National Park, and is of affinity to the large, purple-flowered species G. sanariapoana and G. guianensis. An identification key to all Genlisea species north of the Amazon is presented.

This study evaluated the Arctiini fauna of the Serra do Pardo National Park (Pará, Brazil) between 22 September and 3 October 2011. Light traps were left one night in each sampling site (SS) from 18:00 h to 6:00 h of the next day. The following parameters were evaluated: richness (S), abundance (N), diversity index (H’), Shannon uniformity (U) index, and Berger-Parker dominance (BP). Richness was estimated using the non-parametric methods Chao1, Chao2, ACE, ICE, Jackknife1, Jackknife2 and Bootstrap. A total of 3,247 specimens were captured, belonging to 221 Arctiini taxa; 32 of these are new records for the state of Pará and, of these, six are new records for the Brazilian Amazon. The Arctiini fauna is very rich and uniform. The richness estimator and rarefaction curve indicated the need for increased sampling efforts in the area.

Amazonian Forests

Two new species of the largely Brazilian Didymopanax clade of Schefflera (Araliaceae) are here described, illustrated, and compared to similar taxa. Both are from poorly sampled areas in the Brazilian Amazon Basin. Schefflera prancei is known only from the Serra do Divisor National Park, at the border between Brazil and Peru. It differs from the similar S. confusa by its leaflets with narrowly elliptic to oblanceolate blades, with an acuminate to cuspidate apex, and the light brown to grayish sericeous indument on the abaxial blade surface. The second new species, Schefflera pubicarpa, is found in central Amazonian forests, and differs from similar species of the clade by a combination of characters, including a large-tree habit, leaves with 8 to 10 leaflets, inflorescences with ascending secondary branches and lacking tertiary branches, flowers with trichomes along the styles, and pubescent fruits. While this species appears to have a restricted distribution in Brazil, a westward extension reaching into Peru, Colombia, and Ecuador may be likely as new collections from intermediate areas become available.

A New Species

Isertia psammophila, a new species from the white-sand campinarana forests in Northern Brazilian Amazonia is here described and illustrated. While molecular evidence indicates that it is closely related to I. rosea, I. parviflora and I. spiciformis, morphologically it is most similar to I. rosea by its short stipules and glabrescent leaves. Isertia psammophila occurs in sympatry with I. rosea and I. parviflora in the Viruá National Park, Roraima, Brazil, and these three species can be easily differentiated by morphological characters, which are here discussed.

A New Species

Bazzania amadoi is a new species described and illustrated here based on material collected during a study of the bryophyte flora in the Brazilian Amazon Mountains, Monte Roraima National Park, Roraima State, Brazil. Bazzania is the largest genus of Lepidoziaceae,with ca. 30 species recognized in South America. A combination of leaves slightly bifid and recurved to the ventral side, underleaves imbricate and connate with the leaves on only one side, and vittae absent with only a region of larger leaf cells in the mid-lower portion of the leaves (vitta-like), distinguishes B. amadoi from the similar B. gracilis. The new taxon is placed within the key for the identification of species from the Brazilian Amazon domain, and represents an addition to the rich endemic flora of the Brazilian Amazon mountains of the Guiana Highlands. A detailed illustration of the new species is included, and also its informal conservation assessment.

Sticherus holttumii, a new species from Brazil, is here described, illustrated, and compared to its most similar species. Additionally, S. brevitomentosus is recorded for the first time in Brazil, based on a recent collection from Pico da Neblina National Park. We also provide an identification key to all species of Sticherus from the Brazilian Amazon.

The Amazonian toadheaded pitviper Bothrocophias hyoprora (Amaral, 1935) is known from Brazil (states of Amazonas and Rondônia), Colombia, eastern Equador, Peru, and Bolivia. We report the first record of this species from the state of Acre (Brazil) in the Serra do Divisor National Park. This record extends the species distribution in 540 km to the southwest of Tabatinga, state of Amazonas, which was the nearest record of this species in Brazilian Amazon.
