Description. Adult male. Length 1.4–1.6 mm (mean 1.5 mm, n = 4), holotype 1.6 mm (from tip of head to wing apices). Forewing length 1.1–1.3 mm (mean 1.2, n = 4), holotype 1.3 mm. General color, in alcohol, pale yellow. Antennae 18–segmented, unmodified; each with scapus cylindrical, pedicel cylindrical, apical flagellomere short and with small projection ( Fig. 2A View FIGURE 2 ). Ocelli absent. Posterior setal warts of head triangular. Maxillary palps 5- segmented; labial palps 3-segmented. Legs covered by golden setae, tibial spur formula 0–2–3. Wings unmodified, without flaky patches; fore- and hind wings with main veins present ( Figs 2B, 2C View FIGURE 2 ). Forewings, in alcohol, uniformly brown, with light brown setae; each with Sc incomplete, ending just after middle of wing length; apical forks 1, 2, and 3 present ( Fig. 2B View FIGURE 2 ). Hind wings narrow, more acute than forewings; each with Sc incomplete; apical forks 1 and 2 present ( Fig. 2C View FIGURE 2 ). Mesoscutellum with transverse suture. Metascutellum rectangular, short and wide. Sternite VII without apicomesal process ( Figs 2E, 2F View FIGURE 2 ).
Male genitalia. Segment VIII annular. Segment IX reduced ventrally; anterior margin concave with elongate anterolateral apodemes extending into segment VI in dorsal and ventral views ( Figs 2D, 2E View FIGURE 2 ); ventrally above bases of inferior appendages with posteromesal margin deeply U–shaped in ventral view ( Fig. 2E View FIGURE 2 ); posterior process with rounded apex in lateral view ( Fig. 2F View FIGURE 2 ). Tergum X membranous with deep V–shaped incision in dorsal view ( Fig. 2D View FIGURE 2 ); lobate in lateral view ( Fig. 2F View FIGURE 2 ). Inferior appendages long, slightly sinuous, each with projecting and round apex in ventral view ( Fig. 2E View FIGURE 2 ); triangular, slightly upturned and pointed posterodorsal in lateral view ( Fig. 2F View FIGURE 2 ). Subgenital plate complex, divided into dorsal and ventral processes; ventral process plate-like, incised apically, forming two round lobes apically in ventral view ( Fig. 2E View FIGURE 2 ); dorsal process more sclerotized, inflated mesally, narrow apically and basally ( Fig. 2E View FIGURE 2 ); both processes curved downward in lateral view ( Fig. 2F View FIGURE 2 ). Phallus tubular ( Figs 2G, 2H View FIGURE 2 ), apex divided into two asymmetrical lobes both curved to left and dorsal lobe slightly more curved in dorsal view ( Fig. 2G View FIGURE 2 ); in lateral view apical lobes curved upward ( Fig. 2H View FIGURE 2 ); ejaculatory duct protruding subapically ( Figs 2G, 2H View FIGURE 2 ).
Diagnosis. The male genitalia of Flintiella angrisanoae sp. nov. are similar to those of F. panamensis Harris, Flint & Holzenthal 2002b , F. tamaulipasa Harris, Flint & Holzenthal 2002b , and F. yanamona Harris, Flint & Holzenthal 2002b , mainly due to the ventral posteromesal U–shaped notch in segment IX and the deeply incised phallic apex. However, the new species can be distinguished from those by sternite VII lacking an apicomesal process ( Figs 2D, 2E View FIGURE 2 ), the inferior appendages being longer and slightly sinuous ( Fig. 2D View FIGURE 2 ), the subgenital plate being complex, divided into dorsal and ventral processes ( Figs 2D, 2E View FIGURE 2 ), and the apex of the phallus being divided into two asymmetrical lobes, curved to the left in dorsal and ventral views, with an ejaculatory duct protruding subapically ( Figs 2F, 2G View FIGURE 2 ).
Etymology. This species is named in honor of Dr Elisa B. Angrisano, for her outstanding contributions to the genus Flintiella and to the study of Neotropical Trichoptera .
Distribution. Brazil (MG).
