Diagnosis

This species is most similar to A. belchiores Thomson & Holzenthal, 2010 , resembling it in the shape of the elongate intermediate appendages. While in A. belchiores the intermediate appendages are bifid basally, with dorsal and basoventral branches, in the new species they are not branched, the basoventral branch lacking. Additionally, the species can be easily distinguished by the structure of the phallus, which has an ovate lateral process in A. lattesi sp. nov., while in A. belchiores it is elongate and bifid. The phallic guide is also less robust and more hook-like in the new species.

Etymology

The species is dedicated to the Brazilian physicist Cesare Mansueto Giulio Lattes, who was born at Curitiba in Paraná state in 1924 and died in 2005. César Lattes was one of the most distinguished and honored Brazilian physicists, and his work was fundamental for the development of atomic physics. He was one of the discoverers of the Pion (pi meson), a subatomic particle, and one of the main personalities behind the creation of Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) and Centro Brasileiro de Pesquisas Físicas (CBPF).

Description

ADULT. Length of forewing 4.10–4.75 mm (n = 10). In alcohol, general color yellowish brown, with golden brown sclerites; antennae stramineous, dorsum of head golden brown, with pale yellow and dark brown setae; thorax and legs yellow, legs segments with brown setae; wings pale yellow, forewing with fine pale yellow 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, narrow basally, enlarging apically, ventral margin slightly convex; in ventral view, little longer than wide, narrow at base, enlarging to apex, apical margin slightly convex. Phallic guide darkly sclerotized, elevated over inferior appendages; in lateral view, strongly arched, base broad, apex rounded, reaching middle of inferior appendage. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view, short, subrectangular, apex rounded; in ventral view, lateral lobes moderately elongate, directed posterolaterally, posterior margin slightly concave, not crenulated. Tergum X divided into pair of semimembranous subtriangular lobes, lobes bulbous, bearing slender setae along inner margin; in lateral view, subrectangular. Preanal appendages long, surface setose, margin slightly crenulated, wider at base, gently tapering apically, apex rounded. Intermediate appendages long, narrow, almost same length as preanal appendage; in lateral view, rod-like, strongly curved dorsad, with 1 stout mesal seta and 1–2 stout subapical setae. Phallus with sclerotized phallobase and membranous apical region; lateral process short, elongate oval, widest subapically, with 1 spine at apical third and a row of 3 spines at apex, the mesal one 2 times longer than the others; in dorsal view U-shaped, elongate, with only 2 apical spines visible; without basomesal process.

Distribution

Brazil (SC, SP).
