Diagnosis
This species is most similar to
A. absaberi
sp. nov.
,
A. donagrazielae
sp. nov.
and
A. taquaralis
, belonging to the
taquaralis
Group, as discussed previously. This species can be distinguished from all other members of the
taquaralis
Group by the posterior margin of sternum IX strongly convex, the preanal appendages with crenulated margins and by the very elongated lateral lobes of inferior appendages. Additionally, the more robust phallic guide and the presence of a tuft of small mesodorsal microsetae at intermediate appendages are useful characters to diagnose
A. gusmaoi
sp. nov.
Etymology
The species is dedicated to the Brazilian priest and inventor Bartolomeu de Lourenço Gusmão, who was born at Santos in
São Paulo
state in 1685 and died in 1724. Bartolomeu de Gusmão was the first Brazilian inventor and scientist, famous for the creation in 1709 of the hot air balloon.

Description
ADULT. Length of forewing
5.15 mm
(n = 1). In alcohol, general color golden brown, with golden brown sclerites; antennae stramineous, dorsum of head 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, narrow basally, enlarging apically, ventral margin slightly convex; in ventral view, about 2 times as long as wide, enlarging apically, apical margin strongly convex. Phallic guide darkly sclerotized, not highly elevated; in lateral view, arched, base broad, apex rounded, reaching middle of inferior appendage. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view, elongate, subtriangular, apex rounded; in ventral view, lateral lobes very elongate, directed posterolaterally, posterior margin concave, not crenulated, with mesal emargination. Tergum X divided into pair of semimembranous oval lobes, lobes bulbous, bearing slender dorsal setae; in lateral view, ovate, elongate. Preanal appendages long, surface setose, margin slightly crenulated, wider at base, tapering apically, apex rounded. Intermediate appendages long, approximately ¾ length of preanal appendage; in lateral view, wide at base, tapering apically, curved dorsad near apex, with 3 spine-like setae at apex; tuft of small microsetae mesodorsally. Phallus with sclerotized phallobase and membranous apicoventral region; lateral process elongate, bifid; dorsal branch long, wide, with 2 spines at apical third and 1 long spine at apex; ventral branch narrow, with 1 apical spine; without basomesal process.
