NEOSTETHYNIUM Ogloblin, 1964

( Figs 659–676 View FIGURE 659 View FIGURES 660–664 View FIGURES 665–667 View FIGURES 668–671 View FIGURES 672–676 )

Stethynium (Neostethynium) Ogloblin, 1964: 106 . Type species: Stethynium (Neostethynium) stenopterum Ogloblin, 1964 , by original designation. Raised to genus by Huber, 1987: 827 and Yoshimoto, 1990: 45.

Diagnosis. Head in lateral view with vertex almost horizontal and forming a right angle with posterior surface of head ( Fig. 659 View FIGURE 659 ); face with faint subantennal sulci ( Fig. 660 View FIGURES 660–664 ); clava 3-segmented, the segments separated by transverse sutures ( Figs 659 View FIGURE 659 , 665 View FIGURES 665–667 ); mandibles small, their apices not touching when closed ( Figs 660, 661 View FIGURES 660–664 ); ocelli forming an equilateral triangle ( Fig. 663a View FIGURES 660–664 ); scutellum with 1 posterolateral seta and with campaniform sensilla abutting ( Fig. 666 View FIGURES 665–667 ); frenum entire ( Fig. 666 View FIGURES 665–667 ); genitalia at base with a dark reddish colour ( Figs 669, 671 View FIGURES 668–671 ). Male mandibles large, crossing when closed, each with 2 equal ventral teeth and a dorsal serrate apically rounded tooth ( Fig. 672, 673 View FIGURES 672–676 ).

Discussion. Neostethynium is one of three Nearctic genera with clava 3-segmented. It differs from Krokella by having fore wing narrow, venation shorter than half length of wing, and frenum entire. It differs from Stethynium by the mandibles; in Stethynium the mandibles in both sexes have 4 equal teeth.
