Agenamyia exotica de Carvalho & Couri, 1992 View in CoL
( Figs. 5A–D View FIGURE 5 , 14A, C View FIGURE 14 )
Diagnosis. This species is similar to Agenamyia timida de Carvalho, Wolff & Fogaça sp. nov. in general appearance. Tarsi are blackish, with 2–3 yellowish fore tarsus segments.
Measurements (n=3): body length = 3.8–4.1 mm. Wing length = 3.5–3.8 mm.
Redescription. Head. Male. Light brown fronto-orbital plate with 6–7 setulae. Light brown frontal vitta. Light brown parafacial and with silver pruinosity. Dark brown palpus with a lighter base. Dark brown antennae and lighter pedicels. Light brown arista.
Thorax. Dark brown mesonotum, without stripes. Dorsocentral 1+3, first postsutural 1/4 smaller than the third Two postsutural intra-alar setae, the posterior weak. Anterior katepisternal seta were very similar to background setulae.
Wings. Clear. Whitish calypteres.
Legs. Yellowish with apical femora and blackish tibia. Fore tibia with a row of pv setae in apical third. Hind femur on av with three apical setae. Hind tibia with 2–3 apical av setae.
Abdomen. Syntergite 1+2 conspicuously yellowish.
Terminalia ( de Carvalho & Couri, 1992: 23, Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 ). The cercus is divided into two parts, much longer than wide, with a parallel apex and setulae at the base. Surstylus much shorter than the cercus.
Female. Measurements (n=3). Body length = 4.1–4.4 mm. Wing length = 3.5–4.0 mm.
Similar to males. Anterior katepisternal similar to posterior ventral katepisternal. Legs distinctly light brown. Hind femur with two av setae in apical half (median one found in males is lacking). Abdomen with tergite 3 less conspicuously yellowish.
Ovipositor ( de Carvalho & Couri, 1992: 23, Figs. 5–7 View FIGURE 5 View FIGURE 6 View FIGURE 7 ). Tergite 6 is divided longitudinally, and tergites 7 and 8 are large and divided longitudinally. Sternites 6 and 7 are undivided and covered with a few setulae; sternite 8 is divided, reduced, and covered with a few setulae. Epiproct has one pair of strong setae. Large, very setulose hypoproct. Three spermathecae.
