Hermanella amere sp. nov. appears to be related to Hermanella guttata Domínguez & Flowers, 1989, sharing with this species several characteristics as the general pattern of coloration of the wings, predominance of orange color in body parts as well as some similarities in general morphology of male genitalia - among them the presence of broad projection in the subgenital plate and penis robust spine. However, these two species can be easily distinguished from each other by the abdominal color pattern and shape of penis lobe.	en	Do Nascimento, Jeane M. C., Salles, Frederico F.

CE5587F3FFE52E439496FA69FA1CEE28.taxon	discussion	Comments. The imago of Hermanella nigra sp. nov. appears to be related to Hermanella thelma Needham & Murphy, 1924, sharing with this species the general predominance of black color in body parts as well the subgenital plate with broad projections. However, these two species can be easily distinguished from each other by the wing color pattern and shape of penis spine. According to Domínguez & Flowers (1989) the genus Hermanella is closely related to Hylister and Needhamella, and the main characteristics that distinguish Needhamella from Hermanella are: relatively wider prosternum in Needhamella; the medial projection on clypeus – present in Needhamella and absent in Hermanella; gills ending in a single finger-like process in Needhamella and gill with two lateral lobes and a digitiform apical projection in Hermanella; lateral apical denticles present on tarsal claws in Needhamella and absent in Hermanella; and smaller number of setae on dorsal surface of labrum in Needhamella. Lima et al. (2012), based on the shape of the gills and on the fact that the medial projection on the clypeus showed intraspecific variation in nymphs of N. ehrhardti examined by them, described a new species of Needhamella, N. mazama Nascimento, Mariano & Salles, 2012. Still according to Lima et al. (2012), the remaining diagnostic characteristics of Needhamella presented by Domínguez & Flowers (1989), and mentioned above, were considered of specific value and restricted to the type-species, N. ehrhardti. With the description of a second species with intermediate characters between Needhamella and Hermanella, i. e. gills ending in finger-like process (as in N. ehrhardti), but with prosternum narrow and lateral apical denticles absent on tarsal claws, we decided to maintain the generic diagnoses proposed by Domínguez & Flowers (1989) to the genus Needhamella. Therefore, it is necessary to transfer N. mazama to the genus Hermanella, as follows: Hermanella mazama (Nascimento, Mariano & Salles, 2012), new combination. We modified the key to male imago of South American species of Hermanella (Domínguez et al. 2006 pg. 392) to accommodate Hermanella amere sp. nov., Hermanella nigra sp. nov. and Hermanella mazama n. comb. Hermanella costalis (Navás, 1934), a species transferred with reservations to the genus (Peters et al. 2005), is also included.	en	Do Nascimento, Jeane M. C., Salles, Frederico F.

CE5587F3FFEA2E5A9496F9FCFCECE91E.taxon	discussion	Comments. The imago of Hy. obliquus sp. nov. appears very similar to Hy. chimaera Kluge, 2007, sharing with this species the same pattern of coloration on body and wings. However, both species can be distinguished by the styliger plate, which has a pair of pointed projections near base of forceps in the new species and a pair of large protuberances, each bearing a very small non-sclerotized point on its apex, in Hy. chimaera. The nymphs can be distinguished based on the presence, in the new species, of a subapical denticle much larger than others in the tarsal claw. Besides that, nymphs of the new species possess a unique gill shape. While in Hy. plaumanni Domínguez & Flowers, 1989 and Hy. chimerae the apex is truncate, bearing long slender processes, on the new species the apex also bears these processes, but it is excavate rather than truncate.	en	Do Nascimento, Jeane M.

Nymphs and male imagos are tentatively associated by sharing the same color pattern of legs and by basal portion of the dark wing pad of the nymph, which corresponds to the colored basal portion of the adult's wing. The two associated stages were also collected at the same place.	en	Do Nascimento, Jeane M. C., Salles, Frederico F.

CE5587F3FFF32E519496FCA3FA16E925.taxon	discussion	Comments. The new species is similar to Traverella (Traverella) bradleyi (Needham & Murphy, 1924) due to the color pattern and by the shape of the spine on penis. However, it can be distinguished from this species by the lateral margin of penis, which is sinuous in the new species and straight in T. (T.) bradleyi, and by projections of the male styliger plate – broad, short and medially united in the Traverella insolita, sp. nov. but long and narrow in T. (T.) bradleyi (Domínguez et al. 2006). With respect to the color pattern, same to is also observed in other species of the genus or even in other genera of the Hermanella complex, such as Traverella longifrons Lugo-Ortiz & McCafferty, 1996, Hermanella mazama (Nascimento, Mariano & Salles 2012) (in Lima et al. 2012), Hylister chimaera Kluge, 2007 and Hylister obliquus sp. nov. (see above). Among the diagnostic characteristics of Traverella insolita, sp. nov., the styliger plate strongly projected posteriorly, hindering the vision of penes is very unusual. The same feature is observed in Thraulodes criptodrylus (Nieto & Domínguez, 2001) and recently, Gonçalves et al. (2012) also stated this character for Poranga nessimiani (Gonçalves & Da-Siva). However it is probably a convergence since these genera are not closely related. Domínguez (1995) established a new subgenus Traverella (Zonda), and used the following characters to distinguish the imago of the subgenus Traverella (Traverella): vein ICu 1 of fore wing attached to vein CuA (as seen in new species) and male styliger plate with long, narrow paired projections. However, the species herein described presents the male styliger plate with broad and short projections. With respect to the immature stage, all characters proposed for the subgenus Traverella, but one, were observed in the nymphs analyzed (tusk present at inner anterior angle of maxillae, segment II of maxillary palpi long, segment III of labial palpi not elongated and gills present on abdominal segment seven). The single exception lies on the presence of a row of spine-like setae on the fore tibia, a characteristic attributed to the subgenus Zonda. Moreover, the nymph of Traverella insolita, sp. nov. is the first of the genus in which the frontoclypeal projection is absent and the first with a prominent tusk on galea-lacinia, characteristics that must be included in the generic diagnoses proposed by Allen (1973) and Domínguez et al. (2006). Despite having many congruent characters with representatives of Traverella (Traverella), the new species has a number of derived characters, as well as other intermediaries among the two subgenera proposed for the group, not fitting securely in any of them. Based on this scenario, we hypothesize that either the concepts used in subgeneric diagnoses must be modified or a new subgenus should be erected to accommodate the new species. In the absence of a phylogenetic analysis, we prefer to keep the new species not attributed to any subgenera. In order to incorporate the male imago of Traverella insolita, sp. nov. the following modification is proposed to the key of Domínguez et al. (2006, p. 514).	en	Do Nascimento, Jeane M.
