SCHIZOPHRAGMA Ogloblin, 1949 View in CoL View at ENA

( Figs 884–911 View FIGURE 884 View FIGURES 885–889 View FIGURES 890–892 View FIGURES 893, 894 View FIGURES 895, 896 View FIGURES 897–902 View FIGURES 903–906 View FIGURES 907–911 )

Schizophragma Ogloblin, 1949: 345 . Type species: Schizophragma basalis Ogloblin, 1949 , by original designation.

Diagnosis. Body length 465–740 μm. Face with subantennal sulci; mandible with 5 teeth ( Figs 885 View FIGURES 885–889 , 902 View FIGURES 897–902 ), clava 2- segmented ( Fig. 890 View FIGURES 890–892 ), frenum longitudinally divided, each half longer than wide ( Figs 891 View FIGURES 890–892 , 903 View FIGURES 903–906 ); second phragma (mesophragma) with indented apex ( Fig. 896 View FIGURES 895, 896 ).

Discussion. Four other genera in the Nearctic have a longitudinally divided frenum: Anagrus , Krokella , Platystethynium (Platypatasson) and Stethynium . Schizophragma differs from Anagrus and Stethynium by having the clava 2-segmented, a feature shared only with Anaphes (Patasson) , Omyomymar and Platystethynium (Platypatasson) , and from the latter by the wide fore wing and body not dorsoventrally flattened. In some slide mounts a “secondary transverse trabecula” is visible between the toruli and the transverse trabecula ( Fig. 885 View FIGURES 885–889 ). It is divided into several (5) short horizontal sections. The longer vertical section along inner orbit lateral to each torulus is the preorbital trabecula separated from the true transverse trabecula by a wider gap than normal. This is an artefact of slide preparation when the head swells during maceration in KOH; the “secondary transverse trabecula” does not appear on micrographs ( Fig. 897 View FIGURES 897–902 ). It shows, at least in Schizophragma , that the trabecula may be more complex than previously thought.

Nearctic hosts. Unknown. Extralimital hosts are Hemiptera : Membracidae .
