(Figs. 2 A–B, Figs. 3 A–C)
Material Examined. Holotype. Male. Brazil: Santa Catarina: Urubici, Cachoeira do Avencal, 1229 m a.s.l., S28°02.798, W49°37.070, 08.i.2010, net, HF Mendes, LC Pinho & RA Moretto col. (MZSP).
Measurement. Holotype, male: head width, 1.0 mm; pronotum width, 0.83 mm; pronotum length, 0.64 mm; forewing length, 7.9 mm; hind wing length, 6.7 mm; antenna length, 8.1 mm; 15 cercomeres.
Description. Tupiperla pinhoi sp. nov. is a medium sized species. General color brownish to ochraceous. Head brownish with a lighter area in front of the coronal fork, and laterally to the eyes (Fig. 2A); ocelli and eyes black; anterior part of frons brown; labrum light brown, darker than clypeus; lateral part of the head, behind the eyes, with a dark brown band. Maxillary and labial palpi ochraceous. Antenna light brown. Pronotum squarish, light brown, narrower than the head and with some little setae covering it (Fig. 2A). Legs light brown, covered with thin bristles; femur with disto-ventral spine; tibia with two distal spurs; tarsi with tarsomere 1 medium, tarsomere 2 short, and tarsomere 3 long. Wings membranous, light brown; forewing with a conspicuous darker pattern bordering veins and crossveins; pterostigmatic crossvein absent, RA unforked, RP forked and CuA long-forked; hind wing with M3+4, near its separation from M1+2, fused with CuA in part of its length, CuA short forked, 6th anal vein fused with hind margin of wing (Fig. 2B).
ARG, Argentina (MIS, Misiones Province); BRA, Brazil (BA, Bahia State; ES, Espírito Santo State; GO, Goiás State; MG, Minas Gerais State; PR, Paraná State; PE, Pernambuco State; RJ, Rio de Janeiro State; RS, Rio Grande do Sul State; SC, Santa Catarina State; SP, São Paulo State); PRY, Paraguay (PRI, Paraguarí Department);?, when Froehlich (1969) described nymph of T. gracilis, the genus was considered monotypic; however, according to Froehlich (1998), it is likely that the nymph described in 1969 belongs to another species of the genus.
Male. Abdomen brownish to ochraceous with slightly lighter band on abdominal terga 1–9. T10 light brown to ochraceous. T10 extension, in dorsal view, large, distally darker, ending in two separated and out curved teeth (Fig. 3A); in lateral view, straight dorsally and with a clear latero-ventral band (Fig. 3C). Paraprocts, in ventral view, thin, medially curved with thin bristles internally and conspicuous minute teeth on dorsal (outer) margin (Fig. 3B); in lateral view, with constant width over most of its length, dorsal margin darker and medially covered with minute teeth, distal region with an accentuated hook-shaped curvature (Fig. 3C). Subgenital plate ochraceous, ovoid-shaped and with apex prolonged between the paraprocts (Fig. 3B). Epiproct absent.
Female and nymph. Unknown.
Remarks. Tupiperla pinhoi can be distinguished from the congeners by the shape of the paraprocts and the T10 extension in males. The median dorsal margin of the paraprocts in T. pinhoi are covered by minute teeth, and the distal region has a distinct hook-shaped curvature. Only T. illiesi, T. reichardti Froehlich, 1998, and T. serrulata sp. nov. have minute teeth on the dorsal margin of the paraprocts. However, in T. illiesi each paraproct has a small and thin latero-distal spine, whereas in T. reichardti, each paraproct has a large latero-medial spine and in T. serrulata sp. nov., the paraprocts lack a lateral spine.
Tupiperla pinhoi was collected in 2010 at the Avencal Waterfall, at 1229 m a.s.l. in the municipality of Urubici, Santa Catarina, Brazil. The waterfall is 100 m high and it formed by the Funil River. The common vegetation in the area is the “avenca” (Pteridaceae: Adiantum sp.).
Etymology. The specific name pinhoi honors Prof. Dr. Luiz Carlos de Pinho for his contribution to aquatic entomology, especially related to Brazilian chironomids.
