A new species of Deguelia (Leguminosae, Papilionoideae) from the Brazilian Amazon Basin

Deguelia decorticans, a new lianescent species of Leguminosae from the Brazilian Amazon, is here described and illustrated. The new species has flowers which resemble those of Deguelia duckeana and Deguelia rariflora and it might be closely related to them, probably forming a species complex. However, this new species can be easily distinguished by some morphological and reproductive characteristics.

Red Coloration

A new species of Elachistocleis (E. magnus) is described from the Amazon basin, in the municipality of Espigão do Oeste, state of Rondônia, Brazil. It differs from all other species of the genus by the combination of the following characters: i) size larger than 31 mm in adult males, ii) grayish ventral coloration, iii) presence of large post-commissural glands, iv) lack of red coloration in the body, and v) grayish dorsum in preserved individuals. There is dimorphism between males and females in size, structures and coloration. Vocalizations and larvae remain unknown.

A New Species

The loricariid genus Peckoltia currently encompasses 13 valid species ranging throughout the Amazon basin in Brazil, Venezuela, Colombia, Peru, and Guyanas. Peckoltia is included in the tribe Ancistrini, but its relationships with other taxa within the tribe are not well established. In this paper we describe a new species of Peckoltia from the rio Tapajos drainage, Para State, Brazil. Peckoltia compta, new species, is characterized by a bold color pattern consisting of large dark transversal bars on body and thick longitudinal dark stripes on snout and head. The new species is most similar in color pattern to P. vittata but can be distinguished from all its congeners by the presence of a pale line inside each dark stripe running from the snout tip to anterior margin of eyes (vs. absence of such clear lines and a mottled appearance in P. vittata, and a mix of vermiculations and spots on the head of the remaining congeners). A brief discussion on the taxonomic status of the nominal species Peckoltia vittata is also presented.

A New Species

Abstract—A new species, Hymenaea jeaniana, is described and illustrated. The species is known from one of the best-sampled reserves of Amazon Rainforest, the Reserva Adolpho Ducke, in Manaus, and from protected areas of the municipality of Presidente Figueiredo, in Amazonas, Brazil. Previously, the species has been mistakenly assigned to the circumscription of the morphologically similar H. parvifolia, but differs in certain leaflet, inflorescence, and flower characteristics. The new species has a restricted distribution and is assessed as Endangered following IUCN Red List criteria. Based on herbarium collections and field studies, we present a full species description, an illustration, conservation status, and taxonomic comments. An identification key to the Hymenaea species of Brazil is also provided. There are six species of Hymenaea in the Amazon Basin, including the species described herein.

A New Species

The subgenus Trichopygomyia Barreto, 1962 of the phlebotomine genus Lutzomyia França, 1924 is reviewed. This subgenus corresponds to the informal species group longispina of Theodor (1965). Lutzomyia (Trichopygomya) ratcliffei n.sp. from the Brazilian Amazon Basin is described. Figures, keys, distribution maps and notes on ecology are presented for all the known forms. The better known species are most frequently encountered in armadillo burrows and, therefore, could well be vectors of Leishmania.

The genus Ctenostylum Macquart, 1851 was known only from two male specimens, one from Brazil and one from Costa Rica. Ctenostylum fuscomaculatum n. sp., is described based in one female specimen collected in the Amazon Basin, the third specimen known. The diagnosis of the genus Ctenostylum is redefined and its relationships with other ctenostylid genera are discussed.
