Diagnosis
This species resembles
A. bracteatus
in the shape of its intermediate appendage, which is elongate, club-shaped and possesses stout spine-like setae near its apex. However,
A. chagasi
sp. nov.
can be easily distinguished from
A. bracteatus
by its more elongate and crenulated preanal appendages, and especially by the general structure of the phallus, which has a branched lateral process, with a long finger-like ventral branch, whereas in the formerly described species the lateral process is shorter and not branched.
Etymology
The species is dedicated to the Brazilian sanitary physician, scientist and bacteriologist Carlos Justiniano Ribeiro Chagas, who was born at Oliveira in
Minas Gerais
state in 1879 and died in 1934. Carlos Chagas described, in 1909, the disease named after him (Chagas disease) as well as the etiological agent (
Trypanosoma
) and the vector (hematophagous insects,
Triatoma infestans
Klug, 1843
). The deed of discovering all the links in the epidemiological chain of an infectious disease was absolutely unprecedented in the history of medicine.

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 crenulated, parallel-sided, apex rounded. Intermediate appendages long, narrow, approximately ⅔ length of preanal appendage; in lateral view, club-shaped, enlarged apically, with 3 stout spine-like setae at apex (subapically positioned in dorsal view). Phallus with sclerotized phallobase and membranous apicoventral region; lateral process moderately elongate, bifid; dorsal branch short, robust, pointed posterodorsoapically, with 2 spines on distal half, the shorter one positioned on small projection; ventral branch long, finger-like in lateral view, wider at base in dorsal view, rounded apically, with 3 spines, 1 positioned on small projection near base, 1 almost at median region, and 1 at apex; without basomesal process.
