Key to New World Schizopteridae View in CoL
1 Forewing with four closed submarginal cells ( Fig. 1A View FIGURE 1 , black arrows); eyes relatively large, head wider than prothorax ( Fig. 1A View FIGURE 1 ); labium four-segmented; male sternum VIII well-developed; ovipositor well-developed............................. Hypselosomatinae View in CoL ( Williamsocoris Carpintero and Dellapé View in CoL , Glyptocombus Heidemann, Ommatides Uhler View in CoL , Hypselosomops Hoey-Chamberlain and Weirauch View in CoL , Hypsohapsis Hoey-Chamberlain and Weirauch View in CoL )
- Forewing with less than four closed submarginal cells ( Fig. 1B View FIGURE 1 , black arrows); eyes smaller, head not noticeably wider than prothorax ( Fig. 1B View FIGURE 1 ); labium three- or four-segmented; male sternum VIII reduced, fused with pygophore; ovipositor welldeveloped or obsolete................................................................................. 2
2 Labium four-segmented ( Fig. 1C View FIGURE 1 )........................................................................ 3
- Labium three-segmented ( Fig. 1D View FIGURE 1 )...................................................................... 6
3 The basal half of the forewing with a deep costal fracture ( Fig. 1E View FIGURE 1 , black arrow)............................................................................................ Guapinannus Wygodzinsky and Tropistotrochus Reuter
- The basal half of the forewing without a deep costal fracture ( Fig. 1B, F, K View FIGURE 1 )...................................... 4
4 Eyes large, about 2/3 as wide as synthlipsis; basal cell of the forewing much smaller than trapezoidal cell, or if larger then only three veins excluding claval veins emanate from trapezoidal cell; veins are often traced by areoles ( Fig. 1F View FIGURE 1 ); tarsal formula 2- 2-3 in both sexes.............................................................. Peloridinannus Wygodzinsky
- Eyes small, about 1/3 or less as wide as synthlipsis; basal cell of the forewing larger or equal to trapezoidal cell; four to five veins excluding claval veins emanate from trapezoidal cell; veins are not traced by areoles; tarsal formula different...... 5
5 Labium straight and long, extending beyond hind coxa ( Fig. 1G View FIGURE 1 , black arrow); tarsal formula 3-3- 2 in males, 2-2- 2 in females; body size <1.3 mm; ovipositor vestigial............................................... Chinannus Wygodzinsky
- Labium short, not surpassing middle coxa ( Fig. 2F View FIGURE2 ); tarsal formula 3-3- 3 in males, 2- 2-3 in females; total size> 2 mm; ovipositor well-developed ( Fig. 9B View FIGURE 9 )........................................................... Meganannus View in CoL , n. gen.
6 Labium truncated ( Fig. 1D View FIGURE 1 , white arrow); pronotal collar absent ( Fig. 1I View FIGURE 1 , white arrow)..................................... Corixidea View in CoL genus group ( Corixidea Reuter, Hoplonannus McAtee and Malloch, Membracioides McAtee and Malloch, Oncerodes Uhler View in CoL , Voccoroda Wygodzinsky , Voragocoris Weirauch View in CoL )
- Labium tapering ( Fig. 1C View FIGURE 1 , white arrow; 1G, black arrow); pronotal collar usually present ( Fig. 1K View FIGURE 1 , grey arrow).......... 7
7 Cu-vein on male forewing thickened and darkened (see Fig. 44 in Wygodzinsky 1948); macropterous, 1AN vein on forewing merges with Cu distally; right side of the male sternum IV with a hook..................... Itagunannus Wygodzinsky
- Cu-vein on male forewing not thickened and darkened; in macropterous specimens 1AN disappearing before reaching any other vein or forewing margin ( Fig. 1B View FIGURE 1 , white arrow); right side of male sternum IV without a hook................... 8
8 Posterolateral spine on metepisternum well developed ( Fig. 1H View FIGURE 1 , white arrow); radial (= posterior costal) cell pentagonal or quadrate ( Fig. 1B View FIGURE 1 , grey arrow), considerably smaller than anterior costal cell, distal R-vein straight......................
. the Schizoptera View in CoL genus group ( Ceratocomboides McAtee and Malloch, Ptenidiophyes Reuter , Schizoptera Fieber, Orthorhagus McAtee and Malloch, Kophaegis McAtee and Malloch View in CoL ) - Posterolateral spine on metepisternum absent ( Fig. 1K View FIGURE 1 , white arrow); radial (= posterior costal) cell elongate ( Fig. 1J View FIGURE 1 , black arrow), slightly smaller than anterior costal cell, distal part of R-vein curved...................................... 9
9 Head moderately to greatly elongated ( Fig. 1K View FIGURE 1 ), but without frontal projection; labium very slender, curved dorsad at apex, second labial segment much longer than first and third combined ( Fig. 1K View FIGURE 1 , black arrow); basal and discoidal cells separate ( Fig. 1J View FIGURE 1 , grey arrows).......................................... Nannocoris Reuter and Soekhnandanius Makhan View in CoL
- Head not elongated, but with a frontal projection bearing three stout setae (see Fig. 2 View FIGURE2 in: Wygodzinsky 1947); labium moderately slender, not curved dorsad at apex, second labial segment roughly as long as either first or third; basal and discoidal cells merged (see Fig. 1 View FIGURE 1 in: Wygodzinsky 1947)........................................... Biturunannus Wygodzinsky
