Description. Tupiperla guariru n. sp. is a small to medium size species of the genus. Holotype, male: forewing length, 7.9 mm; antenna length, 6.0 mm; number of cercomeres, 12; paratypes, males (n= 7): forewing length, 6.2–8.1 mm; antenna length, 6.1–7.2 mm; number of cercomeres, 11–12; females (n= 5): forewing length, 8.0– 8.7 mm; antenna length, 7.8–9.2 mm; number of cercomeres, 11–13.

General color dark brown. Head dark brown with lighter triangular area in front of the coronal bifurcation and lighter spots laterally to the paired ocelli; in some specimens, anterior part of frons lighter; clypeus and labrum light brown; three ocelli and compound eyes black; in lighter individuals, lateral part of the head, behind compound eyes, with a distinct dark brown band; maxillary palpi 5-segmented, brown, with the last segment darker; labial palpi brown and 3-segmented; antennae brown. Thorax dark brown; pronotum with rugosities and narrower than the head; legs brown, tibia and tarsi darker; in prothoracic legs, ventral femoral spine small (most females) or absent (most males), in meso- and metathoracic legs, femoral spine present; forewing light brown with many crossveins, pterostigmatic cell without crossvein.

Male. Abdominal terga of the segments I–III mainly white, remaining segments mainly brown; tergum X with triangular white patch in the base and with small extension (figure 1); abdominal sterna brown with white patches, which vary in size with the segment; subgenital plate dark brown ( Fig. 3 ); paraprocts dark brown, in lateral view, they expanded progressively towards the apex, which is rounded with a small pointed tooth on posterodorsal portion ( Fig. 2 ).

Female. Abdominal segments I–VII membranous; sternum VII with two strong spots; subgenital plate sclerotized and robust, surpassing segment IX apex and reaching segment X ( Figs. 4–5 ); segments IX and X sclerotized and dark brown.

Remarks. Tupiperla guariru has a tergum X extension similar to that of T. modesta ; however, the paraprocts of both species are different. In T. guariru , the paraprocts expand progressively towards a rounded apex, with a small pointed tooth on the posterodorsal portion, whereas in T. modesta , the paraprocts are similar width throughout their length, ending in a rounded apex. Additionally, males of T. guariru have a rounded posterior subgenital plate margin, but in T. modesta this structure is pointed. Females of T. guariru lack lateral extensions of the subgenital plate, which are present in T. modesta .

Etymology. “Serra do Guariru ”, an indigenous name for the mountain range “Serra da Jibóia”, Bahia State, the region where the specimens were collected. The word “ Guariru ” means water reservoir in the Tupi language. The name is used as a noun in apposition.
