ABSTRACT

The first list of the species of Ephemeroptera from Pernambuco State, Northeastern Brazil, is presented. The survey was based on collections from numerous rivers and streams of 17 counties. A total of five families, 28 genera, and 38 species were recorded, including 22 genera and 31 species newly recorded from Pernambuco State. Moreover, Farrodes tepui Domínguez, Molineri & Peters, 1996, Lisetta ernsti Thomas & Dominique, 2005, and Simothraulopsis (Maculognathus) sabalo Kluge, 2007 are recorded for the first time to Brazil.

Keywords: Mayflies; Neotropical; survey; taxonomy.

RESUMO

É apresentada a primeira lista de espécies da ordem Ephemeroptera do Estado de Pernambuco, Região Nordeste do Brasil. O levantamento foi baseado em coletas em vários rios e riachos de 17 municípios. Foram registrados cinco famílias, 28 gêneros e 38 espécies, incluindo 22 novos gêneros e 31 espécies novas para o Estado de Pernambuco. Além disso, Farrodes tepui Domínguez, Molineri & Peters, 1996, Lisetta ernsti Thomas & Dominique, 2005 e Simothraulopsis (Maculognathus) sabalo Kluge, 2007 são registrados pela primeira vez para o Brasil.

The taxonomic knowledge about Ephemeroptera in the Northeastern Region can still be considered incipient, especially when compared to the Southern and Southeastern regions of Brazil. Based on the list of species of Ephemeroptera recorded from Brazil (Salles et al. 2004), northeastern Brazil was considered the least studied region of the country with only two species recorded at that time. Much of this divergence was caused by the lack of researchers and faunistic inventories in this region, since only one inventory was made for this region, being restricted to just one family and to one state (see Lima et al. 2010).

According to Salles et al. (2012) there are 256 species recorded from Brazil, distributed in 10 families and 68 genera, with 55 species formally recorded from Northeastern Brazil. Although recent studies have contributed to the knowledge about the distribution of the group in this region (Dias et al. 2008; Lima et al. 2010; Mariano 2010, Salles et al. 2010; Cruz et al. 2011; Boldrini et al. 2012), until this study, only eight species were recorded from the state of Pernambuco: Hermanella froehlichi Ferreira & Domínguez, 1992, Hermanella maculipennis (Ulmer, 1920), Hydrosmilodon gilliesae Thomas & Péru, 2004, Hydrosmilodon plagatus Lima, Nascimento & Salles, 2012, Leentvaaria palpalis Demoulin, 1966, Needhamella ehrhadti (Ulmer, 1920), Traverhyphes (Traverhyphes) frevo Lima, Salles & Pinheiro, 2011 and Tricorythopsis spongicola Lima, Salles & Pinheiro, 2011 (Lima et al. 2011, 2012).

In this paper we provide the first inventory of Ephemeroptera from the State of Pernambuco, as well as new records from the Northeastern Region and Brazil.

MATERIAL AND METHODS

The State of Pernambuco is located in the Northeastern Region of Brazil and has an area of 98.311km². The state is divided into three regions according to the physical environment: Zona da Mata (11%), located on the eastern part of the state and characterized by humid climate and Atlantic Forest vegetation; Agreste (19%), a transition zone dominated by semi-arid conditions; and Sertão (70%), centralwestern part of the state and characterized by semi-arid climate and caatinga vegetation (Carvalho 2008).

The material was collected in 34 localities of 17 municipalities located at Zona da Mata (Fig. 1), between March/2009 and February/2011. Nymphs were collected in several submerged substrates (stones, gravels, bedrocks, macrophytes, leafs, woody debris) of each environment by manually picking the specimens or using a D-net. Adults were caught on light traps right after sunset.

Dissected parts of the specimens studied were mounted on microscope slides using Canada Balsam as mounting media. All material was preserved in ethanol 80%. The identifications were based in Dominguez et al. (2006) and Salles (2006), aided by pertaining papers to each taxon. For information about the geographical distribution of species were consulted Domínguez et al. (2006) and the list of species of Ephemeroptera recorded from Brazil on the website "Ephemeroptera do Brazil" updated frequently (Salles et al. 2012).

To analyze the records of the species in river basins, we adopted the classification of the Agência Nacional de Águas. Records of Brazilian states follow official state abbreviations. The material is deposited in the following institutions: Coleção Zoológica Norte Capixaba (CZNC) and Coleção Entomológica da Universidade Federal de Pernambuco (UFPE).

RESULTS AND DISCUSSION

Five families were found in this study (Baetidae, Caenidae, Leptohyphidae, Leptophlebiidae and Polymitarcyidae) distributed among 28 genera and 38 species. In this total 22 genera and 31 species are reported for the first time from the state, whereas the first record of Farrodes tepui Domínguez, Molineri & Peters, 1996, Lisetta ernsti Thomas & Dominique, 2005, and Simothraulopsis (Maculognathus) sabalo Kluge, 2007 are presented for Brazil. These results increased from 55 to 66 the number of species recorded from the Northeastern Region. Below we provide a list of all mayfly species recorded for the state. For each species listed data on geographical distribution are provided, and comments are made when necessary.

Remarks. The nymphs of C. cayumba showed a large variation in the body length (3.6 - 6.2 mm) in which differ the original description by Traver & Edmunds (1968) and the redescription made by Thomas et al. (2001), in which nymphs showed 3.5 mm body length. The distinct pattern of tergal markings also varied, being slightly distinguishable or absent in some individuals. Due the shape of the mouthparts, the number of the tarsal claw denticles, among other characteristics was possible to identify the species.

Lima coll. (UFPE).

Remarks. Based on nymphs, Caenis sp. could be identified as Caenis pflugfelderi Malzacher, 1990, which was previously recoded from AM (Brazil), but a confirmation of this identification was not possible because male specimens reared had damaged genitalia. However, it appears that forceps in these specimens are apically sharp, while in C. pflugfelderi they are rounded. Possibly, in this case, it is a new species, but for confirmation of this species, adult specimens should be obtained from or associated with nymphs.

Miroculis (Miroculis) fittkaui Savage & Peters, 1983

Previous distribution. BRAZIL: Amazon Basin (PA) and Atlântico Sudeste Basin (ES). SURINAME and VENEZUELA.

Material. PERNAMBUCO: Camaragibe, (Rio Besouro 7°59'06.4"S 35°00'13.9"W, 66m), 1 nymph, 08.VII.2009, L.R.C. Lima coll. (CZNC); same as preceding except 3 nymphs, 1 ♀ (reared), 08.IX.2009 (UFPE); same as preceding except 1 nymph, 28.II.2010 (CZNC); Rio Formoso, (Riacho da Gameleira, Reserva Biológica de Saltinho, 8°43'12.3"S 35°10'32.9"W, 47m), 6 nymphs, 24.IX.2009, L.R.C. Lima Coll. (UFPE); same as preceding except 1 nymph, 07.VIII.2010 (UFPE); Tamandaré, (Reserva Biológica de Saltinho, Córrego da Sede S8°43'48.3", W35°10'35.3", 46m), 3 nymphs, 16.XI.2009, L.R.C.

Miroculis sp. Savage & Peters, 1983

Material. PERNAMBUCO: Amaraji, (Rio Amaraji próximo a Usina Amaraji, 8°21'48.9"S 35°28'49.0"W, 320m), 1 ♂ (light trap), 20.I.2011, L.R.C. Lima (UFPE); same as preceding except 1 ♂ (light trap), 21.IV.2012, L.R.C. Lima (UFPE); same as preceding except 2 ♂ (light trap), 28.IV.2012, L.R.C. Lima (UFPE).

Remarks. Using the key to male imagos proposed by Domínguez et al. (2006), Miroculis sp., would key out in couplet 7(6), which includes Miroculis (Miroculis) marauiae Savage & Peters, 1983and Miroculis (Miroculis) rossi Edmunds, 1963. Nevertheless, Miroculis sp. differs from M. (M.) rossi by the size of penes (0.8x the length of forceps segment I in Miroculis sp., 2.0-2.2 in M. (M.) rossi), as well as the number of facets in male compound eyes (14 facets in Miroculis sp., 6 facets in M. (M.) rossi). Regarding M. (M.) marauiae, the shape of penes (not apically hooked in Miroculis sp.) and posteromedian margin of styliger plate (excavated medially in Miroculis sp.) clearly distinguishes them. It probably represents an undescribed species.
