Diagnosis. Tupiperla bispoi differs from its congeners by the following characters: tergum X extension relatively short and simple; subgenital plate rhombus shape, with apex pointed; and male paraprocts bearing a concavity medially to the distal portion in lateral view.

Description. Tupiperla bispoi is a small to medium sized species. Holotype, male: forewing length, 7.5 mm; antenna length, 8.5 mm; number of cercomeres, 16; paratypes: males (n= 27): forewing length, 7.5–8.7 mm (mean= 8.1 mm); antenna length, 8.0– 10.5 mm (mean= 9.25 mm); number of cercomeres, 14–17.

General color light brown. Head light brown with lighter areas in the coronal bifurcation and laterally in the ocelli. Three ocelli and compound eyes black. Labrum light brown, darker than clypeus. Maxillary palps light brown, 5-segmented; first and fourth segments short, second medium, and third and fifth longer; fifth segment slightly darker than the others. Labial palps light brown, 3-segmented with the last two segments slightly darker than the other. Antenna light brown. Pronotum light brown with small lateral expansions dark brown, narrower than the head. Legs light brown to ochraceous. Prothoracic legs with tiny ventral femoral spine in distal position. Meso- and metathoracic legs with femoral spine larger, in distal position; spine toward the distal region of the femur, light brown, slightly wide base and thin at the apex. Tibia with a perpendicular suture in the proximal region and two spurs at the distal region. Forewing light brown with little crossveins evident, pterostigmatic cell without crossveins.

Male. Abdominal terga light brown with slightly clear band in dorsal view. Apical border of the abdominal terga I–VIII dark brown. Apical border of the abdominal sterna I–VIII dark brown. In dorsal view, tergum X has a relatively short extension; base narrower than the apex; lateral margin concave; distal margin slightly curved. In lateral view, tergum X extension has a pointed process directed ventrally. Paraprocts slightly narrowed at the base and slightly expanded medially; dorsal concavity slightly sharp of the medium to distal portion and apex relatively truncated. In ventral view, paraprocts are directed to tergum X extension; distal region with strong lateral curvature, apex truncated. Subgenital plate light brown covered with small and thin bristles; subgenital plate rhombus shaped; apex pointed and prolonged between paraprocts; extends to half tergum X.

Female and Nymph. Unknown.

Remarks. Tupiperla bispoi exhibits size variation of the ventral femoral spine of the prothoracic legs, and meso- and metathoracic legs. However, this spine is always present in all thoracic legs. The short and simple extension of the tergum X resembles that of T. amandae Bispo & Lecci, 2011 , but the latter has paraprocts without a concavity medially to the distal portion (in lateral view), and a “subgenital plate brownish, oval and more sclerotized in its central part” ( Bispo & Lecci 2011). The rhombus shape of subgenital plate of T. bispoi is similar to T. tessellata , but differs from the new species by the thickness of paraprocts (thin in T. tessellata ), and sternum X (slender in T. tessellata ).

Etymology. The specific epithet, bispoi honors Dr. Pitágoras da Conceição Bispo for his contributions to the knowledge of aquatic insects, especially stoneflies.
