Despite the existence of two old, but well known, publications that cite Portuguese localities for the Sialidae (McLachlan, 1880; Navás, 1908), all more recent faunal works fail to report this family from Portugal (e.g., Monserrat, 1986; Aspöck et al., 2001; Aspöck & Aspöck, 2011). We have recently reported Sialidae as a new taxon from Portugal (Badano et al., 2011), but Megaloptera turn out to be relatively well known to aquatic biologists in Portugal (Teixeira et al., 2009).

We have recently reported Sialidae as a new taxon from Portugal (Badano et al., 2011), but Megaloptera turn out to be relatively well known to aquatic biologists in Portugal (Teixeira et al., 2009).Here, a survey of the distribution of Sialidae in continental Portugal is presented within the framework of a collaboration with the Portuguese biodiversity project NaturData (hĴ p://naturdata.com/).RESUMOApesar de duas publicações antigas bem conhecidas citarem localidades em Portugal com presença de Sialidae (McLachlan, 1880; Navas, 1908), várias referências recentes contudo não relatam esta família (e.g., Monserrat, 1986; Aspöck et al., 2001; Aspöck & Aspöck, 2011). No entanto, mais recentemente, esta família foi reportada para Portugal (Badano et al., 2011), sendo a ordem Megaloptera bem conhecida pelos limnólogos portugueses (Teixeira et al., 2009).No quadro de uma colaboração com o projecto NaturData (hĴ p://naturdata.com/) é apresentado um estudo de distribuição de Sialidae em Portugal Continental.INTRODUCTIONThe family Sialidae Leach in Brewster 1815 has a world wide distribution occurring in Europe, North and South America, Asia, eastern Australia, and Paleartic Africa, and about 80 living species. Ten species, all in the genus Sialis Latreille 1802, occur in Europe (Aspöck & Aspöck, 2011), and four of these (Sialis gonzalezi (Vhsivkova, 1985); S. fuliginosa (Pictet, 1836); S. lutaria (Linnaeus, 1758), and S. nigripes (Pictet 1865)) have been recorded from the Iberian Peninsula (Monserrat, 1986). No known recent works prior to Badano et al. (2011) appear to report Sialis species from continental Portugal. There are, however, three older publications that do record sialid species in Portugal (McLachlan, 1880; Navás, 1908, 1915). McLachlan (1880; cfr. pag. 106) reported (with some doubts…) Sialis lutaria from two localities (Figure 1), one in central and a second in northern Portugal. Navás (1908; cfr. pag. 34) cited Sialis fuliginosa from the Portuguese locality of São Fiel (near Paginação_Açoreana_Suplemento 9 - Neuroptera_prova_06.indd   21 13-03-2014   21:25:2122 2013, Suplemento 9: 21-27A Ç O R E A N ACastelo Branco) as San Fiel in a list of Spanish localities (Figure 2); seven years later, Navás (1915; cfr. pag. 202) ascribed the same specimen to the new described taxon Sialis fumosa Navás, 1915, a nomen dubium (Oswald, 2007) likely a synonym of Sialis fuliginosa. Older species-level identifi cations of Sialis, such as those of McLachlan and Navás, are generally regarded as unreliable, because the venational and general morphological traits used in such works are now known to be insuﬃ  cient to accurately separate the modern concepts of species in the genus, which are based primarily on male terminalia (EllioĴ , 1996). A recent collecting trip to northern and central Portugal yielded two adult specimens of Sialis fuliginosa near Serra da Estrela National Park, allowing confi rmation of the presence of that species in Portugal (Badano et al., 2011), a century after Navás’ report. An additional specimen of Sialis fuliginosa was collected in June of 2011 in the Peneda-Gerês National Park (northern Portugal; Oswald pers. com.) during the ‘long excursion’ following the XI International Symposium on Neuropterology (11ISN). A considerable volume of additional Portuguese sialid data has become available through the Aquariport Project (Teixeira et al., 2009) and through collaborations with the staﬀ  of Portuguese biodiversity project NaturData (hĴ p://naturdata.com/).Faunal dataThe primary aim of this study is to document and summarize all known faunal information concerning the genus Sialis in continental Portugal. FIGURE 1. Sialis lutaria in McLachlan’s “Notes on the entomology of Portugal”.Paginação_Açoreana_Suplemento 9 - Neuroptera_prova_06.indd   22 13-03-2014   21:25:2123LETARDI ET AL: SIALIDAE IN CONTINENTAL PORTUGAL These data are summarized in Table 1, based on a compilation prepared for a presentation at the 11ISN (Letardi, 2011).To date, Sialis fuliginosa is the only sialid species that has been defi nitely confi rmed from continental Portugal. However, many confi rmed Sialis specimens that are not identifi able to species have been collected in Portuguese localities that exhibit micro-environmental conditions that are consistent with those where Sialis lutaria and S. nigripes might be expected. As the laĴ er two species are known to be widely distributed in the Iberian Peninsula (Monserrat, 1986), it is likely that one or both of these additional species occur in Portugal as well. In any case, recent documentation of collection localities for Sialis in Portugal (Figure 3), primarily larval specimens (>400) collected in association with the Aquariport project, clearly demonstrate that the Portuguese distribution of Sialis has been severely underestimated previously, and that the genus is broadly present in appropriate microhabitats throughout the north, center, and south of Portugal.ACKNOWLEDGEMENTSWe thank Rui Andrade (Naturdata, Portugal), Armando Caldas (Porto, Portugal), José Manuel Grosso-Silva FIGURE 2.
