Atrichopogon sergioluzi Farias, Santos & Pessoa   sp. nov.

( Figs. 12 A–E View FIGURE 12 ; 13 A–D View FIGURE 13 ; 14 A–E View FIGURE 14 ; 15 A–E View FIGURE 15 ; 16 A–E View FIGURE 16 )

Diagnosis. Male. Only extant species of Atrichopogon   with pigmented wings in the Neotropical region with gonostylus thick, swollen in basal half, with apex bifid with sclerotized inner prong. Female. Without good characteristic features: wing with two distinct darker spots; one large, elliptic spermatheca.

Male ( Fig. 12D View FIGURE 12 ). Head brown ( Fig. 12A View FIGURE 12 ); head width/mouth part length 2.00–2.20 (2.10, n = 2). Ommatidia with interfacet pubescence; broadly abutting medially for length of 4.00–5.00 (4.50, n = 2) ommatidia ( Fig. 12C View FIGURE 12 ). Antenna medium brown, proportions of flagellomeres as in figure 12B; flagellomeres 2–10 fused; plume on flagellomeres 1–9 well developed; 9th flagellomere 0.72 times shorter than flagellomere 10; flagellomeres 11–13 not fused, without plume setae; flagellomere 13 with apical projection not basally constricted. AR 1.10 (1.10, n = 2). Palpus ( Fig. 12E View FIGURE 12 ) medium brown; third segment short to moderately elongated, swollen at mid-length, with welldeveloped, deep pit at midlength; segments 4 and 5 separate. PRIII 2.44–2.86 (2.65, n = 2).

Thorax dark brown ( Figs. 13B, C View FIGURE 13 ). Scutum with setae arising directly from surface, with lateral suture. Paratergite with one seta. Anepisternum well-developed, broadly bilobed posteriorly. Wing with patch of pigmentation in area of r-m and posterior to apex of R 3 ( Fig. 13A View FIGURE 13 ); few macrotrichiae on membrane in apical portion of r 3; wing length 1.03–1.05 (1.04, n = 2) mm; CR 0.66–0.73 (0.71, n = 3). Halter pale. Legs ( Fig. 13D View FIGURE 13 ) yellowish brown, coxae, trochanter, and basal portion of femora lighter; hind tibial spur shorter than width of hind tibia, hind tibial comb with 9–10 spines. TRI 3.33 (n = 1), TRII 3.28 (n = 1), and TRIII 2.48 (n = 1); empodia present.

Abdomen brown ( Fig. 14B View FIGURE 14 ). Ventrolateral dark marks well developed on segments 1–3 and 5–8, smaller on segment 4. Terminalia dark brown ( Figs. 14C, D View FIGURE 14 ), except for lighter gonostylus and cercus; sternite 9 with posterior margin nearly straight; tergite 9 moderately elongate, extending to the level of apex of gonocoxite. Gonocoxite without the medial lobe, gonocoxal apodeme greatly evident, triangular; length 2.00–2.27 (2.10, n = 3) × the basal width. Gonostylus pale brown, except of yellowish brown apical 1/2 ( Fig. 14E View FIGURE 14 ); swollen in basal half, with apex bifid with sclerotized inner claw. Aedeagal-parameral complex ( Fig. 14B View FIGURE 14 ) nearly quadrangular, with short basal laterally directed arms, median portion trapezoidal, apical portion as a long pen feather connected with the median portion and gonocoxal apodeme of gonocoxite. Cercus yellowish brown, elongate, lobe-like, extending beyond the margin of tergite 9.

Female ( Fig. 15B View FIGURE 15 ). Similar to male. Head ( Fig. 15A View FIGURE 15 ); head width/mouthpart length 2.14–2.55 (2.33, n = 3). Eyes broadly abutting medially for length of 3.6–5.0. (4.26, n = 3) ommatidia ( Fig. 15E View FIGURE 15 ). Antenna medium brown ( Fig. 15C View FIGURE 15 ); flagellomeres 1–8 elongate, vasiform. AR 1.53–1.55 (n = 2). Mandibles with 23 teeth. Palpus ( Fig. 15D View FIGURE 15 ) light brown; third segment short to moderately elongated, pit at mid-length; segments 4 and 5 separated. PRIII 2.11–2.44 (2.25, n = 3). Thorax dark brown ( Fig. 16B View FIGURE 16 ). Wing pattern of pigmented membrane as for male ( Fig. 16A View FIGURE 16 ); macrotrichiae on membrane in apical portion of r 3, m 1, and apical half of M 1; wing length 1.10–1.13 (1.11, n = 3) mm. CR 0.66–0.75 (0.69, n = 2). Legs as shown in figure 16C. Abdomen brown ( Fig. 16E View FIGURE 16 ), with lateral black marks; with ventrolateral dark marks well developed on segments 1–3, 5 and 8, smaller on segment 4; segments 8–10 brown. Genitalia. One medium brown, large, elliptic spermatheca ( Fig. 16D View FIGURE 16 ), measuring 115 × 65 (n = 1) μm, with moderate neck 37.5 (n = 1) μm.
