Diagnosis

This new species resembles A. abrachium Thomson & Holzenthal, 2010 by the shape of the elongate segment IX, and by the elongate preanal appendages. It can be distinguished from all other species of the genus by the structure of the intermediate appendages, which are dorsally enlarged near their apex, and bear a single apical spine-like setae on this projection. Additionally, the unusual structure of the phallus, with the dorsal branch of the lateral process short, pointed apically, and the ventral branch widest basomedially, with 2 spines at its apex.

Etymology

The species is dedicated to the Brazilian inventor Alberto Santos Dumont, who was born at Palmira (now Santos Dumont) in Minas Gerais state in 1873 and died in 1932. Santos Dumont is considered the “Father of Flight” and “Aviation Pioneer” because he invented the first true airplane called 14 BIS, which flew a distance of 220 meters at a height of 6 meters and at a speed of about 40 km /h, in Paris on November 12th, 1906.

ADULT. Length of forewing 4.10–5.30 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, enlarging at midlength, ventral margin curved basally; in ventral view, about 2 times as long as wide, enlarged medially, apical margin slightly concave. 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, ovate, apex rounded; in ventral view, lateral lobes very elongate, strongly narrowed, directed posterolaterally, posterior margin concave, not crenulated. Tergum X divided into pair of semimembranous subtriangular lobes, lobes bulbous, bearing slender setae along inner margin; in lateral view, rectangular. Preanal appendages long, surface setose, margin crenulated, widest basally, narrowing apically, apex rounded.
