Previous issue date: 2014-06-20 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Col?mbolos s?o microartr?podes comumente reconhecidos em ambientes ed?ficos.
Entre as formas mais comuns (e mais vis?veis) destes animais, est?o os
Entomobryoidea, um dos grupos mais diversificados de col?mbolos. Embora sejam
registradas mais de 8300 esp?cies de Collembola no globo, no Brasil pouco mais de
310 esp?cies s?o registradas, sendo a maioria no Sudeste do pa?s. No Nordeste, em
particular no Rio Grande do Norte, esses registros ainda s?o reduzidos, mesmo na
Mata Atl?ntica, dom?nio reconhecidamente diverso para esta fauna e de forma
espec?fica, para os Entomobryoidea. Assim, este trabalho teve como principal objetivo
descrever novas esp?cies de Entomobryoidea em remanescentes urbanos de Mata
Atl?ntica no Rio Grande do Norte, especificamente no Parque das Dunas, Natal e na
?rea de Prote??o Ambiental de Genipabu, Extremoz. As coletas foram realizadas nos
meses Julho e agosto de 2012 e Janeiro e Fevereiro de 2013. Os esp?cimes foram
identificados em laborat?rio e descritos de forma detalhada atrav?s de consulta a
literatura espec?fica. Neste trabalho foram descritas quatro novas esp?cies da fam?lia
Entomobryidae: Entomobrya sp. nov. 1, Seira sp. nov. 1, Seira sp. nov. 2 e
Trogolaphysa sp. nov. 1. Seira sp. nov. 1 possui claras semelhan?as com S.
paraibensis, entretanto a quetotaxia do Th. II e Abd. IV distingue ambas as esp?cies.
Estas semelhan?as sugere proximidade filogen?tica entre as esp?cies. Seira sp. nov.
2 ? caracterizado por sua quetotaxia, principalmente na regi?o ?M? cef?lica e pelo seu
Th II. Existe possibilidade de uma rela??o filogen?tica com S. praiana e S. potiguara
devido a algumas semelhan?as. Entomobrya sp. nov. 1 possui poucas semelhan?as
com esp?cies brasileiras, entretanto n?o h? para estas ?ltimas detalhes da quetotaxia
dorsal, o que pode ocultar rela??es de proximidade evolutiva, entretanto, a principal
caracter?stica diagn?stica de Entomobrya sp. nov. 1 frente a outras esp?cies do
g?nero ? a quetotaxia do Abd. IV. Trogolaphysa sp. nov. 1 mostrou acentuada
diferen?a em sua quetotaxia cef?lica dorsal e ao Th II e Abd. IV. A descri??o de novas
esp?cies de col?mbolos, potencialmente end?micas de seus habitats de ocorr?ncia
pode ajudar na compreens?o de padr?es morfol?gicos e evolutivos nos t?xons
amostrados, assim como na preserva??o dos ambientes nos quais foram
encontradas. / Springtails are commonly recognized microarthropods edaphic environments. Among
the most common (and most visible) forms of these animals are the Entomobryoidea,
one of the most diverse groups of springtails. Although more than 8,300 species of
Collembola are registered on the globe, in Brazil a little over 310 species are recorded,
mostly in the Southeast. In the Northeast, particularly in Rio Grande do Norte, these
records are still reduced, even in the Atlantic Forest domain for this admittedly diverse
fauna and specifically, for Entomobryoidea. This study aimed to describe new species
of Entomobryoidea in urban remnants of Atlantic Forest in Rio Grande do Norte,
specifically in Parque das Dunas, Natal in the Environmental Protection Area
Genipabu, Extremoz. The collections were made in the months July and August 2012
and January and February 2013, using entomological vacuums and plastic trays. The
specimens were identified in the laboratory and described in detail by looking at the
literature. In this paper four new species were described Entomobryidae family:
Entomobrya sp. nov. 1, Seira sp. nov. 1, Seira sp. nov. 2 and Trogolaphysa sp. nov.
1. Seira sp. nov. 1 has clear similarities to S. paraibensis, however the chaetotaxy of
the mesothorax and abdomen IV distinguishes both species. The number of
phylogenetic proximity suggests similarities between species. Seira sp. nov. 2 is
characterized by its chaetotaxy, mainly in the 'M' head and his mesothorax. There is
possibility of a phylogenetic relationship with S. praiana and S. Potiguara due to some
similarities. Entomobrya sp. nov. 1 has little resemblance to Brazilian species, from the
point of view of color, however there is for the latter detailing the dorsal chaetotaxy,
which might obscure evolutionary relationships of proximity. Even so, the main
diagnostic feature Entomobrya sp. nov. 1 compared to other species of the genus is
the complexity of the chaetotaxy of the fifth abdominal segment. Descriptions of new
species of Collembola, potentially endemic to their habitats of occurrence may help to
understand the morphological and evolutionary patterns in the sampled taxa, as well
as the preservation of the environments in which they were found.
