Diagnosis
Austrotinodes lenti sp. nov. resembles A. chihuahua Flint & Denning, 1989 in the structure of the moderately elongate club-like intermediate appendages with 3 spine-like setae near its apex. This species is easily diagnosed by the unusual bifid shape of the lateral process of the phallic apparatus, with a short, stout dorsal branch bearing 3 spines at its anterior margin, and a long, slender ventral branch with an apical, very elongate rugose, spine-like seta.
Etymology
This species is dedicated to the Brazilian medical zoologist and entomologist Herman Lent, who was born in Rio de Janeiro in Rio de Janeiro state in 1923 and died in 2004. Herman Lent dedicated himself to studying the vectors of Chagas’ disease, becoming one of the greatest triatomine specialists in the world, and publishing more than 200 scientific papers.

Holotype
BRAZIL: ♂, Minas Gerais, São Roque de Minas, PN da Serra da Canastra, Fazenda Velha, afluente do Ribeirão das Posses (Córrego dos Pombos), 20°14′56.60″S, 46º38′04,90″ W, 997 m, 2 Apr. 2014, J.L. Nessimian, A.L.H. Oliveira, L.L. Dumas and S.P. Gomes leg. (DZRJ).
Description
ADULT. Length of forewing 4.00 mm (n = 1). In alcohol, general color golden brown, with golden brown sclerites; antennae stramineous, dorsum of head dark golden brown, with pale yellow and dark brown setae; thorax golden brown dorsally, light yellow ventrally; legs yellow, legs segments with brown setae; wings pale brown, forewing with fine pale brown setae dorsally.
WINGS. Forewing with R1 forked apically, forks II–V present; hind wing with forks II, III and V, discoidal cell absent.
MALE GENITALIA. Segment IX deeply divided, sternum elongate; in lateral view, margins parallel-sided from distal half, ventral margin curved basally; in ventral view, about 2 times as long as wide, lateral margins almost straight, parallel-sided, apical margin convex. Phallic guide darkly sclerotized, not highly elevated; in lateral view, curved at almost right-angle, base moderately broad, apex rounded, reaching middle of inferior appendage. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view, stout, ovate, apex rounded; in ventral view, lateral lobes extremely elongate, directed posterolaterally, posterior margin highly concave, slightly crenulated, with mesal emargination. Tergum X divided into pair of semimembranous subtriangular lobes, lobes bulbous, bearing slender dorsal setae along inner margin; in lateral view, elongate. Preanal appendages very long, surface setose, margin crenulated, parallel-sided, apex rounded. Intermediate appendages slightly longer than half-length of preanal appendage; in lateral view, club-like, with 3 spine-like setae at apical third, 2 of them positioned subapically. Phallus with sclerotized phallobase and membranous apicoventral region; lateral process elongate, widest at base, ladle-like as viewed laterally; dorsal branch short, with 3 spines at posterior margin, the dorsal one 3 times longer than the ventral ones; ventral branch slender, with an elongate apical spine; without basomesal process.
Distribution
Brazil (MG).
