Tupiperla pinhoi  sp. nov.

( Figs. 2View FIGURE 2 A–B, Figs. 3View FIGURE 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).GoogleMaps 

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. 2AView FIGURE 2); 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. 2AView FIGURE 2). 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. 2BView FIGURE 2).

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. 3AView FIGURE 3); in lateral view, straight dorsally and with a clear latero-ventral band ( Fig. 3CView FIGURE 3). Paraprocts, in ventral view, thin, medially curved with thin bristles internally and conspicuous minute teeth on dorsal (outer) margin ( Fig. 3BView FIGURE 3); 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. 3CView FIGURE 3). Subgenital plate ochraceous, ovoid-shaped and with apex prolonged between the paraprocts ( Fig. 3BView FIGURE 3). 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.
