Youngomyia pouteriae Maia, 2001 (Figs. 25 and 27)

New morphological data. Adult: Head (Fig. 25). Both sexes with flagellomeres 1–2 connated and neck of the flagellomeres setulose. Male flagellomeres with basal loops longer than the medial and distal loops; flagellomere 12 with apical process. Female flagellomere 1 longer than the others; circumfila in two rings slightly sinuose, one ring distal and the other subbasal, interconnected by a longitudinal slightly sinuose strand. Hypopharynx triangular, longer than labrum and apically setulose. Labella with 2 pairs of ventral sensorial setae. Palpus with apical setae. Thorax: Wing: Rs bent at its juncture with R5. Legs: Tarsal claws well sclerotized and two-tootched. Male terminalia (Fig. 27). Gonostylus smaller than gonocoxite, with strongly pronounced striae, delimiting elongated cells, each one with a bristle at its base; separated cerci, setose in all length, with six pairs of longer setae at the apex; aedeagus elongated and claviform. Ovipositor: female cerci oval. Pupal exuviae. Antennal bases short, triangular; cephalic seta short. Two pairs of lower facial papillae, one setose and one asetose. Prothoracic spiracle long, triangular, strongly sclerotized, and slightly serrated at the margin. Abdominal segments 2–8 sclerotized dorso-anteriorly, sclerotized area contiguous with spines.

Material examined. 3♂♂, 6 ♀♀, 3 pupal exuviae and 5 full-grown larvae from Restinga da Barra de Maricá e Itaipuaçu in Maricá and Arraial do Cabo municipality, Rio de Janeiro, Brazil , deposited in the Cecidomyiidae collection at MNRJ, Rio de Janeiro, Brazil .
