Diagnosis. This species is closest to A. prolixus Flint and Denning, differing in the shape and setation of the lateral process of the phallus. In A. longispinum, the lateral process is widest mesally while in A. prolixus it is widest basally. The lateral process of A. longispinum bears 1 elongate mesolateral spine and 1 small apical spine. The lateral process of A. prolixus bears 1 slender and 2 enlarged mesolateral spines and 1 enlarged apical spine. Additionally, the phallus of A. longispinum has a more extensive apical membranous region than that of A. prolixus.
Description. Male. Forewing length 4.6–5.2 mm (n=3). Body sclerites brown, dorsum of head dark brown with pale yellow and dark brown setae; thorax dark brown with pale yellow and dark brown setae dorsally, light brown ventrally; leg segments with brown setae. Forewings covered with fine light brown setae with small scattered patches of pale yellow setae. Genitalia. Segment IX deeply divided, sternum elongated; in lateral view, enlarging apically, ventral margin slightly convex; in ventral view, apical margin convex. Phallic guide sclerotized, elevated over inferior appendages; in lateral view, base broad, apex hooked, reaching middle of inferior appendage; in caudal view, with single indentation. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view, quadrate, apex truncate; in ventral view, lateral lobes triangular, directed posterolaterally, posterior margin with mesal emargination. Tergum X divided into pair of semimembranous oval lobes, separated by shallow emargination, bearing dorsal setae. Preanal appendage long, surface setose, margin crenulated, parallel-sided, apex broadly rounded. Intermediate appendage long, approximately 3/4 length of preanal appendage; in lateral view, straight; bifid basally, with long, straight dorsal branch and very short basoventral branch; dorsal branch bearing 1 short subapical seta, short basoventral branch with 1 short apical seta. Phallus with lightly sclerotized phallobase and membranous apical region; lateral process short, elongate oval, widest mesally, with 1 very elongate, mesolateral spine, and 1 small apical spine; without basomesal process.

N. da Serra dos Órgãos, Rio Beija-flor, 22˚27.063’S, 43˚00.065’W, 1125 m, 27.ii.2002, Holzenthal, Blahnik, Paprocki, and Prather, 1 male (UMSP).
Etymology. Named for the elongate mesolateral spine observed on the phallus.
