Diagnosis
This species resembles A. taquaralis and correlated species by the overall shape of intermediate appendages, but can be easily distinguished by the presence of a row of 4 mesoventrally stout spine-like setae, absent in the previously described species. Additionally, the phallic apparatus is distinctive among the new species and the species of the A. taquaralis complex, with 2 long spines positioned midlaterally at the base of the lateral process and not near apex of dorsal branch as in the other species.
Etymology
The species is dedicated to the Brazilian herpetologist and music composer Paulo Emilio Vanzolini, who was born in São Paulo in São Paulo state in 1924 and died in 2013. Paulo Vanzolini was one of the scientists who contributed to the development of the “Refugia Theory” of tropical diversification. He is also considered as one of the greatest samba composers of the country, with more than 70 musical compositions, including the famous “Ronda”, “Volta Por Cima” and “Boca da Noite”.
Material examined
Holotype
BRAZIL: ♂, São Paulo, São José do Barreiro, PN da Serra da Bocaina, Ribeirão da Prata, 22°46′48.9″ S, 44°36′40.4″ W, 1200 m, 19 Dec. 2010, L.L. Dumas and J.L. Nessimian leg. (DZRJ).
Description
ADULT. Length of forewing 5.00 mm (n =1). In alcohol, general color yellowish brown, with golden brown sclerites; antennae yellow, 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, margins parallel-sided, ventral margin slightly convex; in ventral view, about 1.5 times as long as wide, enlarged near apex, apical margin almost straight. Phallic guide darkly sclerotized, not highly elevated; in lateral view, strongly arched, base broad, apex subacute, not reaching the inferior appendage. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view, elongate, subovate, apex rounded; in ventral view, lateral lobes elongate, directed posterolaterally, posterior margin concave, slightly crenulated, with mesal emargination. Tergum X divided into pair of semimembranous subtriangular lobes, lobes bulbous, bearing slender dorsal setae; in lateral view, subrectangular, elongate. Preanal appendages long, surface setose, margin crenulated, parallel-sided, apex rounded. Intermediate appendages long, asymmetric in holotype, approximately ¾ length of preanal appendage; in lateral view, wide at base, tapering apically, slightly curved dorsad, with a row of 4 midventral spine-like setae, left appendage with small dorsal projection at apical third bearing an apical spine-like seta and a single subapical spine-like seta, right appendage without dorsal projection and with 2 subapical spine-like setae, one more than 2 times longer than other. Phallus with sclerotized phallobase and membranous apical region; lateral process elongate, bifid; dorsal branch long, wide, with 2 long spines basolaterally and 1 apical stout spine at apex; ventral branch narrow, with 1 apical spine; without basomesal process.
Distribution
Brazil (SP).
