(Figs. 12 A–E; 13 A–D; 14 A–E; 15 A–E; 16 A–E)
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). Head brown (Fig. 12A); 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). 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) 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). 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); 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) 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). Ventrolateral dark marks well developed on segments 1–3 and 5–8, smaller on segment 4. Terminalia dark brown (Figs. 14C, D), 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); swollen in basal half, with apex bifid with sclerotized inner claw. Aedeagal-parameral complex (Fig. 14B) 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). Similar to male. Head (Fig. 15A); 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). Antenna medium brown (Fig. 15C); flagellomeres 1–8 elongate, vasiform. AR 1.53–1.55 (n = 2). Mandibles with 23 teeth. Palpus (Fig. 15D) 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). Wing pattern of pigmented membrane as for male (Fig. 16A); 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), 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), measuring 115 × 65 (n = 1) μm, with moderate neck 37.5 (n = 1) μm.
