Lispe pygmaea Fallén, 1825b

Syntypes. 6 males, 3 females of Lispe simplicissima Loew, 1847 , junior synonym of L. pygmaea . Italy (Sicily) .

Mid femur with 2 posterior preapical setae. Mid tibia with 1 median posterodorsal seta; without anterodorsal and anteroventral setae. Hind tibia with 1 anterodorsal seta; without anteroventral and posterodorsal; 1 preapical dorsal. Arolium and pulvillus short. Wing. Costal spine indistinct. Vein M straight. Abdomen. Sternite 1 setulose.

Remarks. It can be easily identified in the keys by Hennig (1960), Pont (1991) and Vikhrev (2012a, 2016). The male and female terminalia were illustrated by Hennig (1960, text-figs 91, 122, 127, plate 19 fig. 389, plate 20 fig. 392). Hennig (1960) did not group this species. The species was assigned to the pumila group by Vikhrev (2012a), but was later transferred to the pygmaea species-complex (Vikhrev 2016), characterized by dorsocentrals 2+3, all strong; mid tibia with 1 posterior seta; hind tibia with only 1 anterodorsal seta; lower parafacial without strong seta; and pulvillus short. In a more recent revision of the Australian species of Lispe by Pont (2019), notes and illustrations of male and female terminalia were given (figs 2–8).
