We report new records of Gnamptogenys caelata Kempf (1967) and Gnamptogenys minuta (Emery, 1896) from Brazil. We also describe Gnamptogenys piei n. sp. from Southeast Brazil. This distinctive new species is known only from a single worker found in leaf litter from montane forests of the Mantiqueira mountains in Itatiaia National Park, Rio de Janeiro State, Brazil. The specimen was collected at 1991 m above sea level, an infrequent altitude for minuta-group ants, usually more common at lower altitudes. The new species is imaged, compared with other minuta-group species, and an updated identification key for all known species of the minuta-group is included. 相似文献

Macromitrium catharinense Paris is a poorly known moss of the family Orthotrichaceae reported from Brazil. In the present paper, Macromitrium catharinense is taxonomically re‐evaluated, resulting in the synonymization of M. drewii H. Rob. from Ecuador and M. catharinense var. gracilius (Müll. Hal.) Paris from Brazil. The phenetic relationships between M. catharinense and other closely related species of Macromitrium from Brazil and Ecuador are also discussed. 相似文献

Characters used un specific identification of Zoraptera are briefly discussed. A list of Neotropical species is given, and the difficulties of associating sexes of some species outlined. Two new species are described and figured (Zorotypus weidneri sp.n., ♂, ♀, Brazil; Z.hamiltoni sp.n., ♂, ♀, Colombia) and additional records and information given on Z.shannoni Gurney (♂, Brazil) and Z.huxleyi Bolivar y Pieltain & Coronado G (♂, ♀, recorded from Brazil for the first time). 相似文献

Lonchocarpus castaneifolius, L. grazielae, L. longiunguiculatus, and L. montanus from Brazil are described and illustrated based on field and herbarium studies. The first species belongs to Lonchocarpus sect. Punctati and is restricted to northeastern Brazil (Bahia state). The other three are included in sect. Laxiflori. Lonchocarpus grazielae is restricted to the southern coastal region (Santa Catarina state), L. montanus is found in northeastern Brazil (Bahia and Piauí states), the west-central region (Goiás and Tocantins states) and the southeast (Minas Gerais state), and L. longiunguiculatus occurs in northeastern (Bahia state) and southeastern (Minas Gerais state) Brazil. 相似文献

A new species ofCroton,C. dissectistipulatus, is described from Amazonian Brazil. This species is superficially similar toC. timandroides from northeastern and southeastern Brazil, but differs in having petiolate leaves with glandular margins, persistent stipules, conspicuous racemose inflorescences, staminate flowers having externally glabrous sepals and 3 stamens, and pedicellate pistillate flowers. The systematic position ofC. dissectistipulatus relative to the sections ofCroton is discussed. 相似文献

Three new species of Habenaria (Orchidaceae) section Nudae from Rio Grande do Sul, southern Brazil, are described and illustrated: Habenaria australis, H. kleinii and H. sobraliana. These are the first records of H. sect. Nudae for the state. Based on the examination of living and dried specimens, a total of 33 species and 400 collections of Habenaria were recorded for Rio Grande do Sul. Based on this survey, an updated checklist of the genus Habenaria for Rio Grande do Sul has been compiled. Four species are known only from this state, while seven other species are restricted to southern Brazil, Argentina and Uruguay. Habenaria hieronymi, previously known only from Argentina, is recorded for the first time from Brazil, and H. brachyphyton, H. ekmaniana and H. melanopoda are new records for Rio Grande do Sul. 相似文献

A new hybrid,Micropolypodium xbradei, from Rio de Janeiro, Brazil, is described and illustrated. It shows intermediate morphology between its parents,M. setosum andTerpsichore achilleifolia, in dissection of blades and veins, and number of sori per segment. New combinations for Brazilian endemic species are presented based on this hybrid and on recent results in grammitid phylogenetics. 相似文献

Two new species of Leptolobium from Brazil are described and illustrated. Leptolobium araguaiense, restricted to northern Brazil, is similar to L. panamense, but differs in raceme length, ovary pubescence, flower and bract length, hilum shape, habit, geographical distribution, and
preferential habitat. Leptolobium multijugum, from midwestern Brazil, is perhaps most closely related to L. glaziovianum, but it has more numerous leaflets and smaller bracts and bracteoles than any other species in the genus. 相似文献

The neotropical genus Atlantoscia Ferrara & Taiti, 1981 includes three species, A. floridana Van Name, 1940, occurring in coastal regions of Florida (USA), Brazil, Argentina, and Ascension and Saint Helena islands, A. rubromarginata Araujo & Leistikow, 1999 and A. petronioi Campos-Filho, Contreira and Lopes-Leitzke, 2012 from Brazil. Two new species from Brazil are here described, one from the state of Bahia and one from the state of São Paulo. All the new species have respiratory areas on pleopods 1–5 exopods. The specimens were collected in areas of Atlantic Forest and in cocoa (Theobroma cacao) plantations. New records of A. floridana and A. rubromarginata and distribution maps are presented. 相似文献
