Lispoides abnorminervis ( Stein, 1911)

Paralectotype. Male. Lectotype in SMT, designated byPont

(2001: 462). Bolivia.

Diagnosis. Length of body. 6.5 mm (male). Head. Male dichoptic, frons about one-third of head-width. Frons dark brown. Fronto-orbital plate, parafacial, face and gena silver pruinose. Ocellar triangle brownish, short, not reaching halfway to lunule. Fronto-orbital plate with few setulae, close to antennal insertion. Eye bare. Antenna dark brown; pedicel with a few setae, 2 of them longer. Arista dark brown, very short pubescent. Palpus dark brown, with many setae. Vibrissa long. Many genal and postgenal setae, as long as vibrissa, some of them curved upwards. Thorax. Scutum dark brown with a little grey dust, with 5 dark brown vittae. With many fine and quite long ground-setulae in addition to the usual setae. Dorsocentrals 2+4. Haltere brownish. Calypters yellowish-white, margins brown. Legs. Brown. Fore femur and tibia with fine and long anterodorsal, dorsal and posterodorsal rows of setae, some with curled tips, especially on apical half of fore femur. Mid tibia with 2 posterior to posterodorsal setae. Arolium and pulvillus enlarged. Wing. Smoky brown, darker near base, along the veins and with a darker spot around cross-vein r-m. Costal spine short. Abdomen. Dark brown, with lateral transverse grey white dusted spots close to the anterior margins of tergites 3–5. Sternite 1 setulose. Tergite 5 with many long and fine setae.

Remarks. Among its congeners the species is easily recognized by the colour-pattern of the wing and the grey white dusted spots on the abdomen. The species can be identified with the key by Stein (1911, as Limnophora abnorminervis ).
