(Figures 3A–3H)

Material examined. Holotype male. BRAZIL: Bahia, Abaíra, Distrito de Catolés, Cachoeira do Guarda Mó, white sheet attraction, 13°49’29”S, 39°10’27”W, el. 1230 m, 30.x.2013, Calor, Dias & Campos leg., 1 male (DZRJ).

Paratypes. Same locality and date as holotype, except 5 males (DZRJ); 5 males (UFBA), 5 males (INPA) .

Description. Holotype. Adult male. Length 1.0– 1.8 mm (mean 1.4 mm, n = 16), holotype 1.8 mm (from tip of the head to wing apex). Forewing length 0.8–1.6 mm (mean 1.2 mm, n = 16), holotype 1.6 mm. General color, in alcohol, pale yellow. Dorsum of head covered by golden setae. Antennae 18–segmented, unmodified; scapus cylindrical, pedicel cylindrical, apical flagellomere short and with small projection (Fig. 3A). Ocelli absent. Posterior setal warts of head triangular, with long golden setae. 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 3B, 3C). Forewings, in alcohol, uniformly light brown, with brown setae; each with Sc incomplete, ending just before middle of wing length; apical forks 1, 2, and 3 present; 3A and 2A anastomosed (Fig. 3B). Hind wings narrow, more acute than forewings; each with Sc incomplete; apical forks 1 and 2 present, forks 3–5 absent (Fig. 3C). Mesoscutellum with transverse suture. Metascutellum rectangular, short and wide. Sternite VII without an apicomesal process (Figs 3E, 3F).

Male genitalia. Segment VIII annular. Segment IX reduced ventrally; anterolateral margins with elongate apodemes extending into segment VI in dorsal and ventral views (Figs 3D, 3E); concave anterior and posterior margins, in dorsal view (Fig. 3D); mesal U–shaped notch posteriorly in ventral view (Fig. 3E); posterior process with round apex and long setae in lateral view (Fig. 3F). Tergum X membranous; slightly sinuous in dorsal view (Fig. 3D); lobate, with small incision mesally in lateral view (Fig. 3F). Inferior appendages long, rectangular, internal margins diverging in the apical third, with round anterior margins; short subapical projection on each ventromesal margin in ventral view (Fig. 3E); triangular, tapering to blunt, setose apex in lateral view (Fig. 3F). Subgenital plate long, more than half as long as inferior appendages, triangular in ventral view (Fig. 3E); divided into two nearly contiguous arms, with acute anterior process directed posteroventrad in lateral view (Fig. 3F). Phallus tubular, apex deeply divided into two symmetrical lobes, both with acute apices slightly curved upward in lateral view (Fig. 3H); both curved to left, right lobe folded beneath left lobe in dorsal view (Fig. 3G); mesoventral process with ejaculatory duct protruding from its apex (Fig. 3H).

Remarks. Flintiella quiteriae sp. nov. shares the following characters of male genitalia with F. andreae Angrisano 1995 and F. heredia Harris, Flint & Holzenthal 2002b: mesal U–shaped notch posteroventrally in the segment IX, inferior appendages long and rectangular, and subgenital plate divided into two contiguous arms. However, the new species can be distinguished from F. heredia by sternite VII of the new species being without an apicomesal process (Figs 3E, 3F) and from F. andreae and F. heredia by the inferior appendages each having a short subapical projection on the ventromesal margin (Fig. 3E) and having the phallus apex deeply incised (Fig. 3H). The new species shares the deeply incised phallus apex with F. carajas Santos, Jardim & Nessimian 2011, F. serrana Gama Neto, Ribeiro, & Passos 2020, F. panamensis, F. tamaulipasa, and F. yanamona . Flintiella quiteriae sp. nov. differs from F. carajas, F. panamensis, and F. yanamona by sternum VII lacking an apicomesal process (Figs 3E, 3F). It can be easily distinguished from F. serrana by its mesal posteroventral U–shaped notch of segment IX (Fig. 3E), by its long inferior appendages each with a short subapical projection on the ventromesal margin (Fig. 3E), and by the subgenital plate divided into two continuous arms in ventral and lateral views (Figs 3E, 3F). This new species also differs from F. serrana and F. tamaulipasa by the phallus having its acute apex curved upward in lateral view (Fig. 3H), curved to the left, with its right lobe folded beneath the left in dorsal view (Fig. 3G), and the ejaculatory duct protruding beneath those lobes in lateral view (Fig. 3H).

Etymology. This species is named in honor of Maria Quitéria de Jesus, the first woman to join the Brazilian Army (1822–1823), for her important contribution to the independence of Brazil.

Distribution. Brazil (BA).
