155B87BEFFF0257EFF56554EFD9FC3A0.taxon	discussion	Remarks. — The Bayesian phylogenetic analysis of the molecular data showed that A. pomerana belongs to Clade Cas defined in Pérez-Losada et al. (2004). With regard to the relationship to other species, this was considered a sister-species of A. leptodactyla (Fig. 3), which occurs in the Rio Uruguay basin on the high plateau of Rio Grande do Sul and Santa Catarina. Nevertheless, there are several morphological differences between these two species. A. pomerana does not bear an extra-orbital sinus, whereas A. leptodactyla possesses this character. The rostrum of A. pomerana is only slightly ligulate, recurved, lacks a carina on the distal third, and ends without a spine on the tip; whereas this structure in A. leptodactyla is of medium length, and its distal end terminates in a spine. A. pomerana has wide chelipeds; its sister species has narrow chelipeds. The relationship of A. pomerana with species found in the Rio Uruguay basin, which at present has no direct connection to the Rio Itajaí basin, can be attributed to a common geological origin of the two basins, which is related to the formation of the Serra Geral in southern Brazil (Ribeiro, 2006). The uplift of the Serra Geral separated the Uruguay and Itajaí-Açú rivers creating the opportunity for new species to arise through allopatric speciation. Morphologically, A. pomerana resembles A. marginata Bond-Buckup and Buckup, 1994, in some aspects, particularly in the slightly arched antero-lateral border of the carapace. However, A. pomerana has a subrectangular palmar crest, and A. marginata has no palmar crest.	en	Bond-Buckup, Georgina, Jara, Carlos G., Buckup, Ludwig, Pérez-Losada, Marcos, Bueno, Alessandra A.

155B87BEFFF2257BFCEF50A9FB8EC65F.taxon	discussion	Remarks. — The new species A. muelleri resembles A. plana Buckup and Rossi, 1977 in the dorsoventrally compressed cephalothorax and the absence of the epigastric and protogastric lobes. However it is distinguished from A. plana by the shape of the chelipeds, which are wider in A. plana; by the configuration of the spines of the carpus; and by the shape of the palmar crest, which is more developed in A. plana. This latter species also possesses an extraorbital spine, which is lacking in A. muelleri. The total length of the cephalothorax of the paratypes (n = 7) reached only 13.43 mm, showing it to be a small-sized species. The species occurs in sympatry with A. jarai in the Ribeirão Garcia in the Parque das Nascentes, an environ- mental preservation area that is among the few localities that shelter species in Atlantic Forest. The Bayesian phylogenetic analysis of the molecular data showed that A. muelleri belongs to Clade Eas defined in Pérez-Losada et al. (2004). Aegla muelleri has a sister relationship to A. leptochela (Fig. 3), with which it shares the delicate form of the chelipeds and the convexity of the carapace. However, the two species differ in relation to the antero-lateral spine of the carapace, which in A. muelleri reaches the base of the cornea, and in A. leptochela does not. In A. muelleri, the extra-orbital sinus and the lobe of the movable finger are lacking, and the palmar crest is subrectangular; whereas in A. leptochela the extra-orbital sinus as well as the lobe of the movable finger are present, and the palmar crest is lacking.	en	Bond-Buckup, Georgina, Jara, Carlos G., Buckup, Ludwig, Pérez-Losada, Marcos, Bueno, Alessandra A.
