Oropezella longifrons sp. nov.

(Figs 59–66, 118)

Diagnosis. Frons long, more than two-thirds length of the face; scutum brown, mesopleuron and mediotergite yellow, scutellum and postpronotal lobe pale brown; scutum entirely covered with scattered pruinescence; femora, fore and mid tibiae pale brown; hind femur pale yellow; tarsi brown; abdomen shiny brown, tergites 3–5 yellow on lateral margins.

Etymology. From the Latin “ longus ” (long), “ frons ” (forehead), in reference to the length of the frons which is almost as long as the face.

Description. Holotype male. Body: 2.7 mm. Wing: 2.7 mm. Head: antenna brown located slightly above middle of head; scape as long as pedicel; postpedicel lanceolate, 2.5 times longer than wide, as long as the scape and pedicel combined; stylus apical, bare and long, about 3.5 times length of antenna. Ocellar triangle protuberant; 1 elongate pair of ocellar setae, proclinate at 45º. Holoptic, frons long, more than two-thirds length of face. Proboscis yellow; palpus brown bearing 1 long apical and 1 shorter lateral bristle. Postcranium dark brown with brown to gray thin pruinescence; postoculars elongate, scattered, upper setae longest. Thorax: sub-shiny, entirely covered with pale brown thin and scattered pruinescence; scutum brown, scutellum and postpronotal lobe pale brown, mesopleuron and mediotergite yellow. Bristles thin, short and scattered; acr and dc uniserial. Differentiated bristles: 1 npl short and discreet; posterior dc not distinctly developed; 1 pal short; 1 long and strong apical sctl and 1 lateral bristle thin and about one-third length of apical. Wing (Fig. 118): sub-hyaline with golden iridescence; R1 meeting C at middle of wing; cell dm emitting 2 veins; cell cu p present. Legs: coxae and trochanters pale yellow; femora, fore and mid tibiae pale brown; hind femur pale yellow; hind tibia pale brown; tarsi brown. Bristles short and weak: mid tibia with 1A at middle and 1D near base; some V elongate bristles on hind femur. Abdomen: tergites brown except tergites 3–5 yellow on lateral margins; sternites pale brown; shiny with pruinescence only on tergite 8. Bristles brown, short, scattered and thin. Terminalia: hypandrium about 1.5 times longer than wide, apex concave (Fig. 59); epandrium not deeply cleft dorsally, epandrial lamellae broadly fused basally (Fig. 60); left epandrial lamella shorter than right with elongate dorsoapical process, robust in dorsal view (Fig. 60), slender in lateral view (Fig. 62); right surstylus short, spoon-like about half length of left (Figs. 63), left surstylus long and slender, curved inwards at mid-length (Fig. 62); articulated distal portion of phallus waved, simple, elongate, about half length of basal portion, basal process slender, about half length of articulated distal portion of phallus (Fig. 61). Female. Similar to male. Ovipositor (Figs 64–66): eighth segment somewhat short; tergite 8 deeply cleft medially on distal margin; sternite 8 narrow, three times longer than wide.
