03DB87D28823FF82D6B0A3BEFCB136C7.taxon	discussion	Discussion. Paracerura airesi sp. nov. resembles P. virgata mainly in the sensillary set from the thoracic segment II to the abdominal segment III, habitus, body chaetotaxy, and number of setae along linea ventralis. However, the new species differs essentially from P. v i rg a t a, P. itatiaiensis and P. serrana sp. nov. by 3 + 3 as and 5 + 5 accp sensilla in the abdominal segment IV and 3 + 3 as and 2 + 2 accp in the abdominal segment V (Table 1). Two of the as sensilla in abdominal segment V in P. a i re s i sp. nov. are robust with rough texture, different from the sensillary pattern of the same segments described in P. virgata. The unguis internal teeth, cited by the authors of P. virgata as present or absent, are always present in P. a i re s i sp. nov. The new species also has a bigger body size and consequently a notably higher number of setae in the tibiotarsi and in the ventral face of manubrium and dens. It was observed the presence of one organite composed by 4 granules in the ventral face of the antennal segment I of the new species, similar to the one described by Deharveng (1978) in the antennal segment II of Pseudisotoma microchaeta Cassagnau, 1959.	en	Mendonça, Maria Cleide De, Abrantes, Eduardo Assis, Fernandes, Liliane Henriques (2009): Two new Brazilian species of Paracerura Deharveng & Oliveira (Collembola: Isotomidae).

03DB87D28827FF8ED6B0A40EFB9237FC.taxon	discussion	Discussion. Comparing the morphology of P. serrana sp. nov. with P. a i re s i sp. nov. and P. virgata, some general similarities were observed: the same sensillary formula from thorax II to abdominal III (4,4 / 3,3,3), number of eyes, postantennal organ, number of setae along linea ventralis, retinaculum teeth and mucro. Unfortunately, it was not possible to compare the sensillary formula of P. serrana sp. nov. with P. itatiaiensis (Arlé, 1959) as the sensillary set was omitted by the author. The paratypes and holotype of this species, according to Arlé, were deposited in the Museu Nacional / Universidade Federal do Rio de Janeiro, but they can not be found and are probably lost. In the samples from Parque Nacional de Itatiaia, at 1600 meters of altitude, we found several specimens of P. serrana sp. nov. that we judged in the occasion to be P. itatiaiensis (Arlé, 1959) because of the similarity in the pigment pattern distribution (more intense in the anterior regions of the mesonotum and metanotum) described by the author. However, the coloration in P. serrana sp. nov. is brownish while the other species of genus, including P. itatiaiensis, present bluish to violaceous pigmentation. Within the species of the genus Paracerura the new species is more similar to P. itatiaiensis by the unguiculus with filament and the internal row of spine like setae on dens. However, in P. serrana sp. nov. the filament is longer and the number (22 – 31) of spine like setae is higher. Another difference between all species is the strong plurichaetosis and the presence of some ciliated macrosetae on the last abdominal segments in P. serrana sp. nov., while the other species show smooth setae. Furthermore, the peculiar aspect of the subapical organite on the segment IV, the dorsal sensillary formula on segment abdominal IV – V, the long femoral seta on legs and the number and patterns of manubrium / dens setae, undoubtedly distinguish the new species from the others species of the genus.	en	Mendonça, Maria Cleide De, Abrantes, Eduardo Assis, Fernandes, Liliane Henriques (2009): Two new Brazilian species of Paracerura Deharveng & Oliveira (Collembola: Isotomidae).
