Description. Tupiperla zwicki  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; ocelli and eyes black ( Fig. 2IView FIGURE 2); clypeus and labrum brownish; lateral part of the head, behind the eyes, with a distinct dark brown band. Maxillary and labial palpi ochraceous. Antenna brown. Pronotum squarish, slightly trapezoidal, light brown, with latero-anterior corners rounded, and narrower than the head ( Fig. 2IView FIGURE 2). Legs light brown and covered by thin bristles; femur with disto-ventral spine present; tibia with two spurs at the distal region; tarsi with tarsomere 1 medium, tarsomere 2 short, and tarsomere 3 long. Wings membranous, light brown; forewing with weak darker patterns 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. 2JView FIGURE 2).

Male. Abdomen brownish to ochraceous, and with paler band on abdominal terga 1–9. T10 light brown to ochraceous; laterally covered with thin bristles. T10 extension, in dorsal view, large, and with apex bifurcated (Yshaped) ( Fig. 7AView FIGURE 7); in lateral view, straight dorsally, distally downcurved and ending in two large teeth ( Fig. 7CView FIGURE 7). Paraprocts, in ventral view, thin, covered with thin bristles, and with distal region out curved ( Fig. 7BView FIGURE 7); in lateral view, thin on base and broadening softly along the length, with ventral margin almost straight, dorsal margin slightly sinuous and darker, and apex rounded ( Fig. 7CView FIGURE 7). Subgenital plate ochraceous, and ovoid-shaped ( Fig. 7BView FIGURE 7). Epiproct absent.

Female and nymphs. Unknown.

Remarks. Tupiperla zwicki  can be distinguished from the congeners by the shape of the paraprocts and T10 extension in males. In lateral view, T. zwicki  resembles T. illiesi  , however, in this species, each paraproct has a row of small teeth on dorsal margin, and the latero-distal region has a spine, while in T. zwicki  there are no teeth in the dorsal margin of the paraprocts, and the distal portion is curved outwards.

Tupiperla zwicki  is described based on specimens collected in municipalities of Orleans and Urubici, Santa Catarina State, Brazil. Four male specimens (including the holotype) were collected from August to January 2013, another male was collected in January 2010. Several females were collected in the same locality but are left unassociated.

Etymology. The specific name zwicki  honors Prof. Dr. Peter Zwick, Schlitz, Germany for his numerous contributions to aquatic entomology, especially on the taxonomy and phylogeny of the Plecoptera  .
