ABSTRACT Seven sites were examined in the Challhuaco-Ñireco system, located reserve of Nahuel Huapi National Park, however part catchment is urbanized, being San Carlos de Bariloche (150,000 inhabitants) placed lower basin. Physico-chemical variables measured and benthic macroinvertebrates collected during three consecutive years at seven from headwater to river outlet. Sites near source characterised by Plecoptera, Ephemeroptera, Trichoptera Diptera, whereas close mouth dominated...
Three new species of Bryophaenocladius Thienemann are described and figured as male imagines: B. urbanus sp. n. from Central Argentina, virgotruncatus nasus Argentinean Patagonia. A geometric morphometric analysis was performed to evaluate the taxonomic value shape anal point in delimitation. The involved 96 species. As a result, showed significant patterns change, recovering three main types: rounded, equilateral triangle-shaped, isosceles triangle-shaped. An identification key Neotropical...
The Puyehue-Cordón Caulle Volcanic Complex eruption occurred on June 4, 2011 (2236 m a.s.l. 40°32′S, 72°7′W). As a consequence, wide areas of Argentina were covered by volcanic ash. In order to investigate the effects ashfall chironomid assemblages, we conducted study at Ñireco River in southwestern part Natural Reserve Nahuel Huapi National Park that crosses city San Carlos de Bariloche, Río Negro, Argentina. We assessed changes assemblage attributes and 18 biological traits, comparing...
Three new species of Pseudosmittia Edwards from the Neotropical region, P. satheri, larga and trapezoidea, are described figured as males. Allocladiusfortispinatus (Edwards), A. globosus Andersen et al. quadrus redescribed on basis material their geographical distribution updated. A phylogenetic analysis was performed in order to assess relationships species. As a result, sœtheri found be sister belonging angusta group. The trapezoidea is group clade ((P. propetropis (P. tropis--P....
The male, female and immature stages of the new species Onconeura analiae from Argentina are described figured. A parsimony analysis including seven known genus plus species, using a combined data set continuous qualitative characters, was conducted in order to assess phylogenetic position give for first time hypothesis genus.
Parapsectrocladius setosus sp. n. is described and figured as pupa male imago, based on material collected in Patagonia, Argentina. The of the new species groups with P. escondido Cranston & Añón Suárez by having anal point tapering triangular; inferior volsella simple, rounded, without any dorsal ridge apically blunt. It can be distinguished from possession strong setae inner margin volsella. New belonging several localities allows us to emend generic diagnosis adult male, female larva...
Paryphoconus peruvianus, a new species from Peruvian Amazonia is described and illustrated femaleand male specimens collected at light in the Department of Cuzco. The compared with its similar congenerP. anomalicornis Kieffer. Furthermore, P. anomalicornis, fusciradialis Spinelli y Wirth oliveirai Lane arefirstly recorded Peru.
The first Argentina records of four species biting and predaceous midges (Diptera: Ceratopogonidae) are provided from the Iberá wetlands in Corrientes Province: Forcipomyia (Euprojoannisia) unica Bystrak Wirth, Echinohelea blantoni Neobezzia fittkaui Wirth Ratanaworabhan Paryphoconus grandis Macfie. This is record midge genus, Macfie, Argentina.
