“…The COI sequences also made it possible to properly associate all nymphs included in the analysis with their respective adults. Among the species of Perlidae from the Paranapiacaba Mountains, seven have known nymphs, including those associated and described in this study [19,22,38,[56][57][58]. Expanding the knowledge about nymphs is a necessary step since only about 20% of Brazilian species of Perlidae have described nymphs.…”

“…Anacroneuria Remarks. This species was described by Bispo and Froehlich [60] and the nymph by Almeida et al [22], both based on material from PEI. This species is brown (Fig 6B ) and has a characteristic hammer and penial armature [60].…”

“…In fact, few nymphs have been associated with adults and described [21]. The nymphs of stoneflies live mainly in streams and are important indicators of environmental quality because, in general, they require well-oxygenated clean water to survive [22]. These requirements contribute to make nymph rearing in the laboratory and subsequent association with adults difficult [23,24].…”

“…These requirements contribute to make nymph rearing in the laboratory and subsequent association with adults difficult [23,24]. Although some authors have successfully associated Neotropical nymphs with adults [16,22,[25][26][27][28][29][30][31][32][33][34], finding a sufficient number of nymphs, keeping them alive during transport, in a laboratory, or in an artificial stream, and feeding them until emergence are challenges that need to be considered. Nymph rearing strategies are very time consuming and can hinder the nymph-adult association, mainly for rare species with narrow environmental tolerance, creating difficulties for a broad research program aimed at describing nymphs.…”

“…Nymph rearing strategies are very time consuming and can hinder the nymph-adult association, mainly for rare species with narrow environmental tolerance, creating difficulties for a broad research program aimed at describing nymphs. In Brazil, many nymphs that have been described were associated with adults by rearing in the laboratory [16,23,26,35] or in streams in the field [16,22,25,26,33,36,37], and few species were associated using molecular tools [21,24,38]. Despite these efforts, currently, only 28 of the 145 species of Brazilian perlids have been associated and described.…”

The study of complementary sources of biological variation (e.g. morphological, molecular) has allowed a better understanding of biodiversity through the construction of an integrative taxonomy. Using this approach, specimens from the Paranapiacaba Mountains, southeastern Brazil, were studied to update the knowledge on the stonefly family Perlidae from the region, characterize the species, and make associations between nymphs and adults using a fragment of the mitochondrial cytochrome c oxidase subunit I (COI) gene. The study also discusses the implications of integrative taxonomy and teneral specimens for the study of South American Perlidae. The molecular data were analyzed using Bayesian inference, Neighbor-joining, and delimiting species methods. Our results revealed that, in general, there was a morphological and molecular congruence between species. In the Paranapiacaba Mountains, three genera and 15 species were recorded: Anacroneuria boraceiensis Froehlich 2004, A. debilis (Pictet 1841) (new record), A. fiorentini De Ribeiro and Froehlich 2007 (new record), A. flintorum Froehlich 2002, A. iporanga Bispo and Froehlich 2004, A. itajaimirim Bispo and Froehlich 2004, A. polita (Burmeister 1913), A. subcostalis Klapálek 1921, A. tupi Bispo and Froehlich 2004 (with a description of the nymph), Kempnyia auberti Froehlich 1996, K. colossica (Navás 1934), K. flava Klapálek 1916, K. neotropica (Jacobson and Bianchi 1905) (including its new junior synonym K. petersorum Froehlich 1996), Kempnyia sp., and Macrogynoplax veneranda Froehlich 1984. COI sequences were obtained for 11 species, five of which had nymphs associated with adults. Among the five associated nymphs, the nymph of A. tupi is described here. The results of this study indicate that the color of adult teneral specimens differs from that of mature specimens. Given this, the synonym of K. neotropica and K. petersorum was proposed since these species have high morphological and molecular similarities and differ only in color patterns. In addition, the previous record of A. petersi Froehlich 2002 from the Paranapiacaba Mountains was invalidated since it was considered a teneral specimen of A. flintorum. These results suggest that the development of an integrative taxonomy is essential to continue advancing the study of Perlidae diversity in South America.
