Genus: Alterosa
Name
Alterosa amadoi Dumas & Calor & Nessimian, 2013 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Remarks
Alterosa amadoi sp. n. cannot be easily placed in any of the species groups defined by Blahnik (2005)[1]. Alterosa amadoi sp. n. and Alterosa caymmii sp. n. share character similarities with Alterosa ruschii Dumas & Nessimian, 2013 and Alterosa spiesae Dumas & Nessimian, 2013, regarding the general structure of the branched intermediate appendages. However, unlike Alterosa ruschii and Alterosa spiesae, the 2 new species cannot be placed in or even near the Alterosa sanctipauli group because of the lack of a basal rounded protuberance on tergum X, with cuticle scabrously developed, and the absence of a crest-like process at the apex of tergum X. Alterosa amadoi sp. n. can be diagnosed by the overall shape of the intermediate appendages, especially the rod-like mesal branch with spines at its apex, and the inferior appendages with the 1st article short and nearly as wide as long. An additional diagnostically unique character for this new species is the dorsal spiny crest-like projection at midlength of tergum X.
Description
Adult. Color (in alcohol) brown; legs, palps, and antennae pale brown, forewing pattern not discernible. Male forewings 5.6–6.4 mm (n=3).
Male genitalia. Tergum VIII with posteromesal margin moderately emarginate; emargination U-shaped and extending no more than halfway to anterior margin. Sternum IX with anterolateral margin weakly rounded, subtruncate; posteroventral margin greatly produced, extending nearly linearly from dorsum (Fig. 1A). Tergum IX greatly reduced, membranous or fused to base of tergum X (Fig. 1B). Tergum X tapered from base in lateral view; dorsally with spiny crest-like projection at midlength; apex sensillate, subtruncate, slightly enlarged in lateral view (Figs 1A, 1B). Intermediate appendages heavily sclerotized, branched subbasally; mesal branch elongate, surpassing preanal appendages, rod-like, blunt and with small spines apically; lateral branch lobe-like, rounded, covered by spine-like setae, subacute apically in dorsal view, apex greatly enlarged and rounded as viewed laterally (Figs 1A, 1B). Preanal appendages elongate, club-like, covered with stiff, small setae; apex rounded with elongate subacuminate projection bearing small apical setae as viewed laterally and dorsally (Figs 1A, 1B). Inferior appendages robust, setose; 1st article, in lateral view, short, nearly as wide as long, bulging mesally; 2nd article longer than 1st article, relatively wide, base as wide as apex of 1st article, slightly enlarged apically and with small pad of short, stiff apicomesal setae (Figs 1A, 1C). Phallobase tubular, relatively short, slightly curved; endotheca without spines; phallotremal sclerites indistinct (Fig. 1D).

Etymology
The species is dedicated to the deceased Brazilian writer Jorge Amado, who was born in Bahia state in 1912 and died in 2001. Amado is one of the most acclaimed contemporary Brazilian novelists, whose 32 novels have sold millions of copies. Among his best-known works are “Capitães de Areia”, “Gabriela, Cravo e Canela”, and “Tieta do Agreste”. In 2012, Brazil celebrated the centenary of his birth.
