Diagnosis

This new species can be distinguished from all other species of the genus by the shape of intermediate appendages, which are slightly curved dorsad near apex, bearing several spine-like setae: 1 long, projecting mesoventral, followed by a row of 4 or 5 lateroventral stout, spine-like setae, and an isolated apical one. The elongate and spinous, oval phallus resembles those of A. bracteatus Flint & Denning, 1989 , A. lattesi sp. nov. and A. costalimai sp. nov.

Etymology

The species is dedicated to the Brazilian medical zoologist and epidemologist Adolfo Lutz, who was born at Rio de Janeiro in Rio de Janeiro state in 1855 and died in 1940. Adolfo Lutz was the first Latin American scientist to study in depth and to confirm the mechanisms of transmission of yellow fever by Aedes aegypti (Linnaeus, 1762) mosquitoes. His dedication to public health was also paramount in the research and fight to control various epidemics in many points in Brazil. Because of this he is recognized as the father of tropical medicine and medical zoology in Brazil.

Description

ADULT. Length of forewing 3.75 – 5.80 mm (n = 10). In alcohol, general color golden brown, with golden brown sclerites; antennae light yellow, 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 elongated; in lateral view, apparently enlarging subapically, ventral margin slightly convex; in ventral view, about 2 times as long as wide, enlarged subapically, apical margin broadly convex. Phallic guide darkly sclerotized, not highly elevated; in lateral view, arched, base moderately broad, apex rounded, reaching middle of inferior appendage. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view, stout, larger at base, apex subacute; in ventral view, lateral lobes elongate, directed posterad, posterior margin convex, not crenulated. Tergum X divided into pair of semimembranous ovate lobes, lobes bulbous, bearing slender dorsal setae along inner margin; in lateral view, elongate, tip pointed. Preanal appendages long, surface setose, margin crenulated, parallel-sided, apex rounded. Intermediate appendages long, almost same length as preanal appendage; in lateral view, parallel-sided, slightly curved dorsad near apex, with 1 projected mesoventral spine-like setae, row of 4–5 lateroventral and 1 apical spine-like setae. Phallus with sclerotized phallobase and membranous apicoventral region; lateral process moderately elongate, oval, widest at midlength, with 1 stout mesolateral spine, dorsal branch long, wide, with row of 3 stout ventral spines near apex, the 2 subapical ones 2 times longer than the more apical one; without basomesal process.

Distribution

Brazil (MG).
