Yellowish-brown; costal spine little longer than the costal bristles; the transverse cross-vein dm-cu slightly curved; vein R 4+5 and vein M straight; cross vein dm-cu in basal half of cell r4+5. Both calypters yellow with yellow margins. Legs . Black, mid and hind femora yellow apically, hind tibia brown yellow apically. Fore femur with rows of dorsal, posterodorsal, and posteroventral setae; fore tibia with one posterior seta, and one strong preapical dorsal seta. Mid femur with 4–5 setae in the basal third on ventral surface; and 3 preapical setae on anterodorsal to posterior surface; mid tibia with 4 posterior setae and 4 apical setae (anterodorsal, posteroventral, ventral, and anteroventral). Hind femur with anterodorsal row and 6–7 setae in the apical middle of anteroventral surface; hind tibia with 4 anteroventral setae, 4 anterodorsal setae and 5–6 posterodorsal setae, calcar absent. Claws and pulvilli with similar size in all three legs. Abdomen ( Fig. 4 D). Dark brown with grey pollinosity. Sternite 5 longer than wide, with several strong setae on the apical third; posterior margin membranous ( Fig. 4 E). Terminalia . Cercal plate longer than wide, with a distal incision; and with two protuberances ( Fig. 4 F), curved backwards at the apex ( Fig. 4 G). Surstylus straight, broad distally, with setae on inner surface ( Figs. 4 F–G). Aedeagus with aedeagal apodeme curved strongly sclerotized, and dilated at the apex; epiphalus sclerotized, paramere slightly bent downward with setula; gonopod with short setulae; and distiphallus tubular, straight, and slightly sclerotized ( Fig. 4 H). Female . Length. Body: 6.00– 6.99 mm , wing: 5.95–6.66 mm . Differs from male as follows: Head : dichoptic, the shortest distance between eyes is 0.74–0.80 mm ; frontoorbital plate setulose with 2 reclinate orbital setae. Postocular setae divergent. Parafrontal plate setulose. Legs . Mid and hind femora black, with a little more than the apical third yellow. Mid femur with a row of anterior setae in the basal middle; 2–3 setae in the apical third of anteroventral surface. Hind femur with only an anterodorsal row setae, and 3 long and curved setae in the basal third on anteroventral surface, hind tibia with only 2 anteroventral setae and 3 anterodorsal setae. Terminalia . Tergite 8 with 2 parallel sclerotized plates, fused and with setulae on the distal margin; epiproct with proximal margin curved, and setulose, cercus digitiform with long setulae ( Fig. 4 I). Hypoproct rounded, sclerotized, with long setulae on distal margin ( Fig. 4 J). Type material examined . ( MNRJ ).

Malloch (1934) described the species from male and female specimens from Ancud, Castro and Puerto Varas, Chile . We provide a redescripton and, for the first time, descriptions of male and female terminalia . Biology . The specimens captured by JCM were collected over rotten meat with a hand net.
