Anacroneuria caraa De Ribeiro & Froehlich, sp. n.

(Figs. 6–10)

Diagnosis. Frons mostly light brown, M–line light, lappets brown (Fig. 6). Genae and parietalia light brown. Antennae and palpi brown. Pronotum pale brownish, darker laterally. Legs brown, mid and hind femora bicolored. Wing membrane and veins light brown, C and Sc paler. Basal cercomere light, rest brownish.

Male. Forewing length, 11.8 mm. Hammer a short truncate cone (Fig. 7). Hooks regularly curved with pointed tips (Fig. 8). Ventral vesicles large. In lateral view, the penial apex bends dorsally (Fig. 10). Dorsal keel absent. Ventral membrane near base of hooks with a scaly appearance (Fig. 9).

Female. Unknown.

Type Material. Holotype, male: BRAZIL, Rio Grande do Sul, Caraá, Rio dos Sinos (29º42'53’’S 50º17'19”W), 0 4. XII. 2003.

Distribution. Known from the type locality.

Etymology. The name refers to the municipality in which it was collected. Noun in apposition.

Remarks. This species was collected together with A. fuscicosta (Enderlein 1909), to which it bears some resemblance. The latter, however, is darker and, medially on the frons, the brown pigment occupies the area from the postfrontal line to the M-line. They are readily separable by their penial armatures; that of A fuscicosta having a ventrally sloping apex, small ventral vesicles and apices of hooks blunt. In fact, the penis of A. caraa, with its lack of a keel, the large ventral vesicles and the upturned apex form a unique combination in the genus. The scaly area in the ventral membrane near the base of the hooks of A. caraa is also uncommon.
