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
