Alterosa caymmii sp. n. Figs 3 A–F

Remarks.

Alterosa caymmii sp. n. is very similar to Alterosa amadoi sp. n., as discussed under that species. It differs in that the lateral branch of each intermediate appendage is apically projecting in Alterosa caymmii sp. n., while in Alterosa amadoi sp. n. it is broadly rounded. Alterosa caymmii sp. n. also differs from Alterosa amadoi sp. n. in the shape of inferior appendages. Additionally, the phallus of Alterosa caymmii sp. n. is more developed, with endotheca bearing several tracts of numerous large spines.

Description.

Adult. Color (in alcohol) brown; legs, palps, and antennae pale brown, forewing pattern not discernible. Male forewings 5.2-6.4 mm (n=10).

Male genitalia. Tergum VIII with posteromesal margin not or scarcely emarginate. Sternum IX with anterolateral margins weakly rounded, subtruncate; posteroventral margin greatly produced, forming broadly rounded expansion (Fig. 3A). Tergum IX greatly reduced, membranous or fused to base of tergum X (Fig. 3B). Tergum X tapered from base in lateral view; apex sensillate, rounded as viewed dorsally, subtruncate and slightly enlarged in lateral view (Figs 3A, 3B). Intermediate appendages heavily sclerotized, branched subbasally; mesal branch moderately elongate, surpassing preanal appendages, slightly curved outward at midlength in dorsal view, rod-like, rounded apically, covered with spine-like setae; lateral branch short, flange-like, covered with spine-like setae in apical half, apex enlarged and rounded in lateral and dorsal views (Figs 3A, 3B). Preanal appendages elongate, club-like, covered with stiff, small setae; apex rounded with small subacuminate projection bearing small apical setae as viewed laterally and dorsally (Figs 3A, 3B). Inferior appendages elongate, linear, flattened on mesal surface, setose; each with 1st article, in lateral view, approximately 2 times as long as wide, tapering apically; 2nd article subequal in length to 1st article, relatively narrow, especially at midlength, apex rounded, with prominent pad of short, stiff apicomesal setae (Figs 3A, 3C). Phallobase tubular, very short, scarcely curved; endotheca elongate, with several tracts; 1 paired tract near base without spines, 1 apicolateral tract with several large spines, and 1 single tract at apex with 2 clusters of small spines; phallotremal sclerites indistinct (Figs 3D, 3E, 3F).

Brazil (Bahia).

Etymology.

This species is named in memory of Dorival Caymmi, considered one of the most important Brazilian songwriters. Caymmi was born in Bahia state in 1914 and died at 2008. He became a national icon with his lyrics that evoked the charm of Bahia’s fishing villages, beaches and beautiful women, like "O Que é Que a Baiana Tem?", “Marina”, "Rainha do Mar", "Samba da Minha Terra", among others.
