Parapsectra wagneri Siebert, 1979

( Figures 7 , 29–31 , 41 )

Material examined. GERMANY. Holotype: adult male labelled: ZSM, Holotypus, design. M. Siebert; Breitenbach Gewächshs., Schlitz/Hess., Datum 25.5.73, Art.: Parapsectra wagneri n. sp., Euparal, M. Siebert. Paratypus: 1 male, same data as holotype except for date: 28.5.73.

Diagnostic description. Adult male (measurements in Table 7 and 8).

Colouration (after Siebert 1979). Yellowish brown, with scutal stripes, postnotum, sternum, haltere and proximal margins of abdominal tergites brownish. Head. Antenna with 13 flagellomeres, distal flagellomeres slightly separated ( Fig. 29 ). Frontal tubercles absent. Third palpomere longer than fourth. Wing. Sc, M, R2+3, proximal 1/3 of M1+2 and proximal 1/5 of Cu bare, remaining veins with macrotrichia. FCu under RM. RM moderately long. Membrane below M mostly bare, below An covered with sparse macrotrichia. Anal lobe of wing strongly reduced ( Fig. 7 ). Legs. Spur of fore tibia absent (?broken). Combs of mid and hind tibiae strongly reduced, usually well separated, with at most 20 teeth 10–12 μm long on each tibia; single spur-like tooth sometimes present (n = 1).

Gonostylus moderately long, slightly bent at base, parallel-sided or subtly broadened in half length and tapering to blunt tip. Anal tergite with long bands of V-type and elevated hump armed with prominent tubercles bearing median setae; lateral teeth absent; anal point stout, ellipse-shaped, broad at base, smoothly tapering to rounded apex, bearing relatively wide crests; entire area surrounding base of anal point covered with microtrichia ( Fig. 30 ). Superior volsella short, triangular, with convex anteromedian margin; digitus small but reaching at least half length of superior volsella; Micropsectra -seta placed on tall cylindrical tubercle ( Fig. 30 ). Median volsella with short stem bearing c. 8–9 broad falciform (basally) and lanceolate (apically) lamellae ( Fig. 31 ). Inferior volsella moderately long, at most reaching gonostylus at half length, straight or finely bent, with slight transverse protrusion and abruptly swollen head-like distal half ( Figs 30 , 41 ).

Adult female, pupa and larva: unknown. For data on biology see Siebert (1979); for discussion on taxonomy see below.
