Lispe pumila ( Wiedemann, 1824)

Syntypes. 9 males, 7 females of Lispa proletaria Becker, 1914 , junior synonym of L. pumila . Taiwan .

Diagnosis. Length of body. 4.5–5.0 mm (male, female). Head. Male dichoptic, frons broad, more than one-third of head-width. Frons dark brown. Fronto-orbital plate golden pruinose. Parafacial, face and gena silver pruinose. Ocellar triangle brown, reaching lunule. Male fronto-orbital plate setulose. Antenna brown, apex of pedicel yellow. Arista brown; bare on apical third. Palpus yellow, gradually enlarged towards apex. Vibrissa long. Thorax. Scutum brown, grey dusted; 3 faint brown median vittae, the median one reaching scutellar disc. Postpronotum and notopleuron grey dusted. Dorsocentrals 2+4, only the posterior 2 pairs long. Haltere yellow. Calypters white. Legs. Coxae grey dusted; trochanters yellow; femora brown, grey dusted, yellow at apex; tibiae yellow and tarsi brownish. Fore tibia without a posterior median seta. Mid femur with 2 posterior preapical setae. Mid tibia with 1 anterodorsal and 1 posterodorsal setae, both median; without anteroventral. Hind tibia with 1 median anterodorsal and 1 submedian anteroventral setae; without posterodorsal; 1 preapical dorsal. Arolium and pulvillus not enlarged. Wing. Costal spine indistinct. Vein M straight. Abdomen. Sternite 1 setulose.

Remarks. The species can be identified with the keys by Vikhrev (2012a, 2016). The habitus was illustrated by Vikhrev (2012a, fig. 7). It belongs to the pumila -group of Lispe (see comments on the group under Lispe angustipalpis ). It was also keyed by Xue and Zhang (2005), but their couplet 32 states that fore tibia has 1 long posteroventral. In a more recent revision of the Australian species of Lispe by Pont (2019), the species was keyed and fully redescribed, and some morphological characters and the male and female terminalia were illustrated ( Pont 2019, figs 460–471).
