Material examined. BR, MA. Holotype male: Carolina, PARNA Chapada das Mesas, Riacho Estiva , 07º06’59.8”S, 47º21’21.0”W, 20–30/IV/2013, F. Limeira-de-Oliveira and T. A. Silva ( CZMA). GoogleMaps

Description. Holotype male: forewing length, 9 mm. General color pale yellow. Head pale yellow and pronotum yellowish; M-line indistinguishable ( Fig. 4A View FIGURES 4 ). Antennae yellowish to ochraceous, scape and pedicel yellowish, flagellum yellowish at the base becoming ochraceous from the third antennomere. Palpi ochraceous. Pronotum pale yellow with two darker stripes laterally, anterior corners not rounded, posterior corners rounded ( Fig. 4A View FIGURES 4 ). Membrane and veins of wings white, hindwings almost translucent; posterior radius, base of anterior cubital and anal veins of forewings darker. Seven cells of various sizes between the medial and anterior cubital veins. Legs pale yellow with a dark stripe dorsally on distal part of the femur. Cerci pale yellow.

Male. Sternum IX with small bristles on the posterior area. Hammer as a simple cone ( Fig. 4D View FIGURES 4 ). Penial armature ( Figs. 4 View FIGURES 4 E–G) truncate apically with a pair of distal vesicles. In the lateral view ( Fig. 4G View FIGURES 4 ), there are small spines on the keel. In the ventral view ( Fig. 4F View FIGURES 4 ), there are subapical shoulders. In dorsal view ( Fig. 4E View FIGURES 4 ), behind the vesicles and the hooks, the shoulders fold inwards. Hooks regularly curved and acute apically.

Female and nymph. Unknown.

Remarks. The penial armature of A. leccii is similar to A. novateutonia Froehlich, 2002 . In dorsal view, both species have subapical shoulders, however, in the new species the sclerotized portion is narrower at the base, gradually expanding to the subapical shoulders. In the same view, the apex of the armature of A. novateutonia has a regular shape, narrowing uniformly to the top, which is irregular in the new species. In lateral view, the keel of A. novateutonia is flattened with lateral striae, in the new species spines are present. The penial armature of A. leccii has also prominent vesicles and is of a different color including different maculation pattern of the head and pronotum than A. novateutonia .

Etymology. The name honors Lucas S. Lecci, one of the pioneers in research on Plecoptera in the northeast region.
