Diagnosis. The male of Flintiella serrana sp. nov. is similar to those of F. carajas Santos, Jardim & Nessimian 2011, F. panamensis Harris, Flint & Holzenthal 2002, F. tamaulipasa Harris, Flint & Holzenthal 2002, F. yanamona Harris, Flint & Holzenthal 2002, and F. manauara Santos & Nessimian 2009 in the similarly shaped inferior appendages and in the phallus apex deeply divided. However, the new species can be easily distinguished from these species by the subgenital plate in ventral view with two pairs of sclerotized processes both downturned apically; the ventral pair are each digitiform, elongate, and fused basally; the dorsal pair is longer and fused along the medial line.
Description. Male. Length 1.6–2.1 mm (n = 6) (holotype = 1.8), measured from front of head to apices of folded wings. General color pale yellow (in alcohol). Head without modifications. Antennae without modifications, each with 18 articles. Tibial spur formula 0-2-3. Fore- and hindwing venation reduced to basal veins. Mesoscutellum with transverse suture. Metascutelum rectangular, short and wide.Abdomen without visible modifications. Segment VII without mesoventral process.
Male genitalia. Abdominal segments VII and VIII annular. Segment IX reduced ventrally; in dorsal and ventral views with anterolateral margins developed as slender, elongate rods extending through segment VII (Figs 2B, 2C). Segment X membranous, fused with dorsum of segment IX, apex irregular in both lateral and dorsal view (Figs 2A, 2C). Subgenital plate in lateral view short, with rounded apex and with two pairs of processes both narrowing to blunt and slightly downturned apices (Fig. 2A, sg); in ventral view about 1/2 as long as inferior appendages, wide basally, incised apically, with two pairs of sclerotized ventral processes, ventral pair each digitiform, elongate, and fused basally, dorsal pair longer and fused along medial line (Fig. 2B, sgv). Inferior appendages each with basodorsal lobe; in lateral view tapering to acute apex (Fig. 2A, ia); in ventral view subrectangular, with bilobed basodorsal lobe, sinuous mesal margin and with stout subapicomesal setae (Fig. 2B, ia). Phallus tubular, deeply divided distally, ejaculatory duct protruding from base of incision (Figs 2D, 2E).
Female, larva, pupa, and egg. Unknown.

Etymology. The specific name “ serrana ” used as a feminine noun in apposition (from the Portuguese feminine noun “serrana” = woman who lives in the mountains) refers to the fact that this species has been collected only in mountainous areas.
