CB6A879B9F1081378CC98BF6FD6C58E7.taxon	discussion	REMARKS: A recent worldwide revision of the subfamily Brachycercinae by Sun & McCafferty (2008), allows us to reconsider the former identification of some nymphs attributed to the genus Brachycercus Curtis, 1835. Our material is in perfect accordance with the diagnosis and characters of Sparbarus. In peculiar, our specimens lack a posteromedial process at the base of the operculate gills, as well as operculate gills with ventral submarginal rows, but without a longitudinal ridge in the sublateral area nor a protruding edge at the posterolateral corner. In Brachycercus, abdominal tergum II has a process at the base of the operculate gills; the posterolateral corner of the operculate gills is distinctly more developed than the posteromedial corner.	en	Zrelli, Sonia, Boumaiza, Moncef, Bejaoui, Mustapha, Gattolliat, Jean-Luc, Sartori, Michel (2011): New reports of mayflies (Insecta: Ephemeroptera) from Tunisia.

CB6A879B9F1081378CC98BF6FD6C58E7.taxon	discussion	This species was first described from Algeria (Soldán, 1986), but was already mentioned from Morocco by Dakki & El Agbani (1983); and later from Tunisia by Zrelli et al. (006). The distribution of Sparbarus kabyliensis is restricted to a maritime humid zone of North Africa (Gagneur & Thomas, 1988). In Tunisia, this species is very rare and has been sampled in a single stream in North Tunisia, the Joumine stream (main tributary of the Ichkeul lake) situated at 90 m a. s. l. This species is the only Brachycercinae so far known from North Africa.	en	Zrelli, Sonia, Boumaiza, Moncef, Bejaoui, Mustapha, Gattolliat, Jean-Luc, Sartori, Michel (2011): New reports of mayflies (Insecta: Ephemeroptera) from Tunisia.

CB6A879B9F1381318CD88BEAFECA58E5.taxon	discussion	REMARKS: The genus Habrophlebia includes six West Palearctic species (Alba- Tercedor, 2000), and is represented in North Africa by two of them: H. fusca (Curtis, 1834) and H. vaillantorum Thomas, 1986 (Thomas et al., 1999). In Morocco, two species are recorded, H. fusca and H. vaillantorum. In Algeria, only H. fusca is known, and in Tunisia this genus is represented by Habrophlebia sp. and H. fusca but this latter record by Kraiem (1986) is probably erroneous (see Thomas, 1998 for complete references therein). Habrophlebia consiglioi can be distinguished from H. fusca and H. lauta as follows: in H. consiglioi nymphs, teeth on the posterior margin of the abdominal terga are of triangular shape, whereas such teeth are quadrangular in H. fusca. Dorsal face of femur with setae pointed and feathered in H. consiglioi, contrary to H. lauta where they are blunt and entire (Belfiore & Gaino, 1984). Larvae of H. consiglioi are also distinguished by the gills baring a small number of filaments in the ventral lamella (1 - 3) and in the dorsal lamella (3 - 6) contrary to H. eldae for which the number of filaments is respectively (3 - 5) and (5 - 11). Our investigations of the egg morphology (Figs 6 - 8) indicates that chorionic structure of the Tunisian specimens is similar to those from Sardinia (Mazzini & Gaino, 1985), bringing further arguments, besides the similarity of the larvae, for the conspecificity of both populations. The discovery of H. consiglioi in Tunisia is of major importance. This is not only the first report of the species in North Africa, but it proves that the species is not endemic to Sardinia as previously thought (Buffagni et al., 2003). To our knowledge, this is the first time such a distribution (Sardinia-Tunisia) is mentioned for circum Mediterranean mayflies. At the moment, we have no information allowing us to decide if H. consiglioi originated from Sardinia and colonized subsequently Tunisia, or the contrary as recently shown for some reptiles (Carranza et al., 2008). All populations of H. consiglioi in Tunisia are restricted to streams of the Northwest area.	en	Zrelli, Sonia, Boumaiza, Moncef, Bejaoui, Mustapha, Gattolliat, Jean-Luc, Sartori, Michel (2011): New reports of mayflies (Insecta: Ephemeroptera) from Tunisia.

CB6A879B9F1581308CD88BE4FCA15E00.taxon	discussion	REMARKS: The concept of the genus Nigrobaetis is discussed by Waltz et al. (1994) and Gattolliat (2004). Thirty one species are known with 14 in the Palearctic region (Waltz et al., 1994; Waltz & McCafferty, 1997; Lugo-Ortiz & de Moor, 2000). The generic attribution of Nigrobaetis rhithralis was subject of several changes. It does not belong to Diphetor as cited by El Alami et al. (2000) because it lacks the distinctive bifid prostheca of the right mandible characteristic of that genus (Lugo- Ortiz & de Moor, 2000). The distribution of Diphetor is restricted to the North of the Nearctic area (Lugo-Ortiz & de Moor, 2000). Müller-Liebenau (1969) divided the genus Baetis in several species groups, a part of them subsequently raised to subgeneric or generic level. The attempt of Jacob (2003) to gather again genera such as Nigrobaetis, Alainites and Labiobaetis into Baetis is no more tenable as Müller- Liebenau’s concept of Baetis has been proven to be highly polyphyletic (Monaghan et al., 2005; Gattolliat & Sartori, 2008). Nigrobaetis rhithralis perfectly matches the concept of Nigrobaetis as defined in Waltz et al. (1994). The presence of the genus Nigrobaetis (first record) and the species N. rhithralis in Tunisia is not surprising as this species was originally described from Algeria and was subsequently reported from Morocco (El Alami et al., 2000).	en	Zrelli, Sonia, Boumaiza, Moncef, Bejaoui, Mustapha, Gattolliat, Jean-Luc, Sartori, Michel (2011): New reports of mayflies (Insecta: Ephemeroptera) from Tunisia.

CB6A879B9F1481308CC98D71FCB258C3.taxon	discussion	REMARKS: In North African region, the genus Procloeon is represented by three species: P. concinnum Eaton, 1885, P. pennulatum (Eaton, 1870), P. stagnicola Soldán & Thomas, 1983. Boumaiza & Thomas (1995) mentioned the presence of this genus in Tunisia but without specific attribution. Several larvae belonging to the genus Procloeon were included in the material collected in many streams of northern watersheds of Tunisia. Based on the morphological characters such as the presence of lateral spines on abdominal segments VI to IX, the shape of the gills and the absence of hindwings, specimens were assigned to Procloeon stagnicola (Soldán & Thomas, 1983). It constitutes the first record of this species from Tunisian running waters, and also the first mention since its original description from Algeria.	en	Zrelli, Sonia, Boumaiza, Moncef, Bejaoui, Mustapha, Gattolliat, Jean-Luc, Sartori, Michel (2011): New reports of mayflies (Insecta: Ephemeroptera) from Tunisia.
