Type material. Holotype, adult male: USA, OREGON, Klamath County, Rocky Point Resort at the Upper Klamath Lake , Recreation Creek (42°28'42"N / 122°05'16"W), 2 June 1982, leg. J.E. Sublette. Paratype: 1 male (same location and date as for holotype). GoogleMaps
Derivation of the name. The specific name, derived from the Latin word meaning hairless, refers to the extensive microtrichia-free area of the hypopygial tergite.
Diagnosis. Tibial apices of mid and hind leg with slight lobes armed with dense curved setae; spurs present, variable in shape. Anal tergite with extensive microtrichia-free area at anal point base. Anal point stout, tongueshaped. Superior volsella abruptly narrowed in distal half and slightly swollen apically. Median volsella with stocky stem bearing 7–8 furcate lamellae. Inferior volsella with distinct dorsomedian ridge and large globular swelling ventrally.
Description. Adult male (n = 2).
Colouration (slide-mounted specimens). Eyes black. Antennal pedicel, tentorium, scutal stripes, scutellum, postnotum, sternum and proximal abdominal segments dorsally brown. Head capsule, antennal flagellum, mouthparts, legs and remaining part of abdomen including hypopygium olive green. Wing and haltere pale greenish.
Head. Eyes reniform, broadly separated. Antenna with 13 flagellomeres, AR ca. 1.1; plume fully-developed. Frontal tubercles more or less conical, 12–20 µm long, 6–8 µm wide at base. Lengths of palpomeres 2–5 (in µm): 36, 91–99, 111–115, 139–143. Clypeus with 13–18 setae.
Thorax chaetotaxy. Ac 4–7, Dc 8–12, Pa 1, Scts 4.
Wing ( Fig. 1 View FIGURE 1 A). Slender; length 1815–1845 µm; max. width 495–540 µm. C, R, distal half of M1+2 and R4+5 with macrotrichia, R1 with 2–8 macrotrichia, other veins bare. Membrane with macrotrichia in distal half of r4+5 and with a few macrotrichia in apical section of m1+2, other cells bare. VR Cu 1.12–1.20.
Legs ( Fig. 1 View FIGURE 1 B–G). Fore leg tibia with slightly curved spur ( Fig. 1 View FIGURE 1 B, C), 12–28 µm long. Combs of mid and hind leg tibiae separated, usually vestigial; spurs variable in shape ( Fig. 1 View FIGURE 1 D–G) and length: ca. 16–24 µm long on mid leg and 24–28 µm long on hind leg. Tibial apices of mid and hind leg with slight lobes armed with dense curved setae ( Fig. 1 View FIGURE 1 D–G). Basitarsus of mid leg with 1–4 sensilla chaetica. For lengths of leg segments and leg ratios see Table 1.
Hypopygium ( Fig. 2 View FIGURE 2 , 3 View FIGURE 3 D). Gonostylus slightly shorter than gonocoxite, 100–120 µm long, stout, broadest at mid length, tapering to tip bearing distinct setal tubercle. Anal tergite with V-type bands, 13–19 median setae arranged irregularly and extensive microtrichia-free area at anal point base ( Fig. 2 View FIGURE 2 A, B). Anal point stout, tongueshaped, with transversely cut apex, bearing 12–13 spinulae and well-developed crests ( Fig. 2 View FIGURE 2 A, B). Superior volsella rounded at base, abruptly narrowed in distal half and slightly swollen apically, covered with dense microtrichia on proximal (swollen) part and with 9–12 setae dorsally; digitus long, with finger-like tip extending far beyond apex of superior volsella ( Fig. 2 View FIGURE 2 A, C). Median volsella stocky, with stem club-shaped, bearing 7–8 furcate lamellae ( Fig. 2 View FIGURE 2 D). Inferior volsella with distinct dorsomedian ridge and large globular and wrinkled swelling ventrally ( Fig. 2 View FIGURE 2 A, 3D).
