A new species of microcaddisfly genus Flintiella Angrisano (Trichoptera: Hydroptilidae) from Amazonas State, Brazil

Abstract

The genus Flintiella was erected by Angrisano (1995) for a species from Argentina and Uruguay. Harris et al. (2002b) reviewed the genus, and described eight species occurring throughout Central and South America. Adults of Flintiella are minute, ranging from 1.5 mm to 2.5 mm in length. The genus is assigned to the tribe Stactobiini and is closely related to Orinocotrichia Harris et al., 2002a. Flintiella and Orinocotrichia share the absence of ocelli, the triangular posterior warts on the head, the elongate apodemes from the anterolateral margin of abdominal segment IX, and the keyhole-like vaginal sclerite of the bursa copulatrix (Harris et al. 2002a; 2002b). Flintiella is distinguished from Orinocotrichia by the structure of the subgenital plate, the presence of a diagonal row of short setae on the forewing, and the anterior position of the vaginal sclerite (Harris et al. 2002b).
Currently, only Flintiella astilla Harris et al., 2002b and Flintiella boracea Harris et al., 2002b are recorded from Brazil. Pes (2005) recorded the occurrence of larvae of the genus from Amazonas State. Now, a new species is described from Manaus municipality, Amazonas State, Brazil.
