“…Macroinvertebrate communities responded to different environmental variables in the four river types. Species of the caddisfly (Atanatolica, Mortoniella, and Helicopsyche), stoneflies (Anacroneuria), and diptera (Paltostoma) are present in the neotropical high mountains that normally inhabit little-impacted sites, with a good water quality and heterogeneous fluvial habitat [64,65]. Similarly, in the present study, these were related to high River Habitat Index in the higher elevations, páramo sites.…”

In the tropical high mountains, human activities have strongly intensified in recent decades. Agricultural frontier movement toward higher elevations, river channel modifications, mining, and urban waste discharge threaten river ecosystem health, which is even more alarming when drinking water supply comes from surface water. The aim of the current study was to evaluate the ecological status of high mountain fluvial networks of tropical Andean catchments based on the definition of different river types. Physical–chemical variables and macroinvertebrate communities were sampled in 90 stations of seven tropical high mountain catchments. River habitat and riparian vegetation quality were further evaluated. K-means classification, using physical and hydro-morphological characteristics, identified six different river types. This classification was further refined to five river types by the analyses of macroinvertebrate communities through multidimensional scaling and analysis of similarity. The anthropogenic pressure gradients, present in the different river types, were inorganic (i.e., conductivity, turbidity), organic (i.e., fecal coliforms), river habitat, and riparian vegetation quality. Macroinvertebrate communities responded to different environmental variables in the páramo, mountain forest with humid shrub, urban, and Tarqui river types. Heterogeneous fluvial habitats and high altitude favored taxa such as Atanatolica, Mortoniella, Helicopsyche, Anacroneuria, Paltostoma, Helicopsyche, Paltostoma, Atopsyche, Pheneps, and Maruina. Chironomidae and Psychoda dipteran were associated with higher biochemical oxygen demand, lower oxygen concentration, high fecal coliforms, and total dissolved solids, while Haitia was linked to elevated nitrate concentrations. Integrated watershed management could benefit from a well-established biomonitoring network, considering different river types, which represents the natural variability of the ecosystems, as well as anthropogenic pressure gradients.

“…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.…”

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.

Two new species of Anacroneuria (A. chiriqui sp. n. and A. ngabe sp. n.) are described from Chiriqui Province, Panama, and compared with related species. One new country record, A. divisa (Navás), is herein recorded and new locality records are presented for several species previously reported from Panama. Three unassociated females, including one species from Bocas del Toro province are described under informal designations. There are now 25 described species of Plecoptera known from Panama.
