Parapsectra uliginosa Reiss, 1969

( Figures 6 , 25–28 , 40 )

Material examined. GERMANY. Paratypes No. 6, 7, 10, 12, 15, adult males slide-mounted, labelled: ZSM, Paratypus, design. F. Reiss; 14.v.68, Parapsectra uliginosa sp. n., Rotes Moor/Rhön, vorderer Teich, leg. Reiss.

Diagnostic description. Adult male (measurements in Tables 6 and 8).

Colouration (after Reiss 1969b). Whole body, except for wing, brown, with scutal stripes, scutellum and postnotum dark brown. Head. Antenna with 6 or 7 flagellomeres, proximal flagellomeres sometimes poorly separated ( Fig. 25 ), AR 0.33–0.42 (when 6 flagellomeres) or 0.29–030 (7 flagellomeres). Frontal tubercles present as tiny swellings. Third palpomere longer than fourth. Wing. Strongly reduced, spatulate, usually nonsymmetrical and differing in length; FCu distinctly proximal of RM; venation and chaetotaxy very specific, as shown in Figure 6 . Legs. Spur of fore tibia slightly curved, 12–16 μm long, but sometimes thoroughly reduced (n = 2). Combs of mid and hind tibiae vestigial, widely separated, with at most 15 teeth, 5–15 μm long, on each tibia; combs usually bearing single, somewhat longer, dark, spur-like tooth. For length of leg segments see Table 6 and Reiss (1969b; presumably mean values given).

fe ti ta1 ta2 ta3 ta4 ta5 Hypopygium. Gonostylus stout, widest in half length, tapering to pointed apex. Anal tergite with long bands of V-type and elevated hump armed with stout tubercles bearing median setae; lateral teeth absent; anal point stout, broad at base, tapering to widely rounded or transversely cut trapezoid apex, bearing long crests; microtrichia-free area surrounding base of anal point small ( Fig. 26 ). Superior volsella variable in shape, triangular or slightly elongated, with anteromedian margin convex; digitus stout but short, variable in shape, reaching half length of superior volsella; Micropsectra -seta placed on tall cylindrical tubercle ( Figs 26, 27 ). Median volsella with short stem bearing c. 15 slender falciform (basally) and fusiform (apically) lamellae ( Fig. 28 ). Inferior volsella stout and long, reaching gonostylus beyond its half length, straight or finely bent and directed laterally, with slight transverse protrusion and stout dense setae on distal half, evenly tapering to rounded apex ( Figs 26 , 40 ).

Adult female, pupa and larva: Reiss (1969b). For data on systematics and biology see Reiss (1969b), Murray & Baars (2006) and taxonomic remarks given below.
