Figs. 1–7
Description. Male. Length from tip of head to end of wings 1.7–2.0 mm. General color, in alcohol, brown. Antennae each with 18 segments, and covered by short golden setae. Frontal area of head with pale yellowish setae. Dorsum of thorax with golden setae. Mesoscutellum divided by transverse suture. Metascutellum rectangular. Legs covered by short dark brown setae; tibial spur formula 0, 2, 3. Abdominal segment VII annular, with short posterior process on venter (Fig. 1). Segment VIII annular. Male genitalia. Segment IX reduced ventrally, dorsally with sclerotized hooks curved downward on posterolateral margin, anterolateral margins developed as thin rods extending through segment VII (Figs. 1, 2). Segment X rectangular in dorsal view, and lobate in lateral view (Figs. 2, 3). Inferior appendages each quadrangular in ventral view, with short round posterolateral projection and short projection on internal apical margin (Fig. 1). Subgenital plate, in ventral view, with short apicomesal incision, slightly projected posterolaterally, ventral process wide and strongly sclerotized, apex curved downward (Figs. 1, 3). Phallus tubular, long, slender, apex divided into 2 lobes, depressed and truncate distally, ejaculatory duct protruding between lobes (Figs. 4, 5).
Female. Length from tip of head to end of wings 1.8–2.0 mm. Antennae each with 17 segments. Coloration and overall features of head and thorax as in male. Abdominal segment VI with short posteromesal process on venter (Fig. 6). Segment VII long and narrowing posteriorly (Fig. 6). Female genitalia. Segment VIII rectangular in ventral view, with ring of setae on posterior margin, internally with pair of elongate apodemes originating at anterolateral margins and extending into segment VI (Fig. 6). Segment IX short, posteroventral margin with slight mesal incision, and internally with pair of elongate lateral apodemes extending into segment VI (Fig. 6). Segment X short and slightly conical, with pair of apical papillae (Fig. 6). Bursa copulatrix widest at midlength, narrowing posteriorly, vaginal sclerite with keyhole structure anteriorly, and bearing several short spines with rounded apices (Fig. 7).
Remarks. Flintiella manauara shares the presence of the dorsal spinal processes on male segment IX with F. boracea and F. astilla, but only in the new species and F. astilla are these processes hook-like. Flintiella manauara differs from F. astilla in the more quadrangular inferior appendages in ventral view, and by the phallus with apex divided. The structure of the phallic apex, which is deeply divided, links the new species with F. panamensis Harris et al. 2002 b, F. tamaulipasa Harris et al. 2002 b and F. yanamona Harris et al. 2002 b. Flintiella manauara can be separated from these species by the presence of the spinal processes on the dorsum of segment IX, by the shape of the inferior appendages, and by the distally wide apical lobes of the phallus.
