Description. Tupiperla ubuntu sp. nov. is a small sized species. General color brown. Head dark brown with lighter area in front of the coronal fork, and laterally to the eyes ( Fig. 2G ); ocelli and eyes black; anterior part of frons darker; clypeus and labrum brown; lateral part of the head, behind eyes, with a distinct dark brown band. Maxillary and labial palpi light brown. Antenna dark brown. Pronotum squarish, with rounded corners, and narrower than the head ( Fig. 2G ). Legs dark brown; femur lighter proximally and darker distally, covered with thin bristles, and with disto-ventral spine present; tibia and tarsi darker, and covered with thin bristles. Wings membranous, brownish; forewing with darker patterns bordering veins and crossveins conspicuous, pterostigmatic crossveins 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 long forked, 6th anal vein fused with hind margin of wing ( Fig. 2H ).

Male. Abdomen brown, with a conspicuous inverted trapezium-shaped clear band on abdominal terga 1–9. T10 dark brown. T10 extension almost black; in dorsal view, fish tail shaped ( Fig. 6A ); in lateral view, ending in two large downcurved teeth ( Fig. 6C ). Paraprocts, in ventral view, thin, apex spoon-shaped, and with several external median bristles ( Fig. 6B ); in lateral view, narrow at the base, expanding toward a truncated apex, which has a subapical dorsal tooth ( Fig. 6C ). Subgenital plate brownish with central area darker, triangular shaped and with apex prolonged between the paraprocts ( Fig. 6B ). Epiproct absent.

Female. Abdominal segments 1–7 milky; St7 with two-minute sclerites. Several thin bristles covering St8–10 and paraprocts. St8 forms a long sclerotized subgenital plate that reaches St10, but do not surpass it; plate with a conspicuous lateral narrowing near the base, gradually widening from the base to the apex ( Figs. 6 D–E). Paraprocts, in lateral view, elongated, apex pointed ( Fig. 6E ).

Nymphs. unknown.

Remarks. Males of Tupiperla ubuntu has a T10 extension that resembles that of T. oliveirai . However, the paraprocts in T. ubuntu are thin and expand gradually towards a truncated apex, ending postero-dorsally in a small pointed tooth. In T. oliveirai , the paraprocts are strongly dilated, bent upward in last third, with a membranous area apically and a subapical dorsal tooth.

Tupiperla ubuntu is described based on male and female specimens collected in the village of Minador River in the municipality of Orleans, Santa Catarina State, Brazil. Most material was collected using Malaise traps from August to December 2013. The number of females collected was 15 times greater than the number of males.

Etymology. The specific name ubuntu is in allusion to the ancient African word (Nguni word) which brings the notion of solidarity, cooperation, respect, and generosity. The name is a noun in apposition.
