NEOSTETHYNIUM Ogloblin , 1964

( Figs 199–205 )

Stethynium (Neostethynium) Ogloblin, 1964b: 106 . Type species: Neostethynium stenopterum Ogloblin, 1964 , by original designation.

Diagnosis. Head in lateral view with vertex flat and at a right angle with face and with occiput ( Fig. 204 ); face with faint subantennal sulcus ventral to each torulus ( Fig. 199a ); toruli separated by about their own height from transverse trabecula ( Fig. 199a ); mandibles small, not meeting when closed, each with at least 1 small tooth ( Fig. 199a ); funicle 6-segmented, clava 3-segmented with the divisions between segments transverse ( Fig. 200 ); frenum entire ( Fig. 202 ); fore wing narrow with rounded apex ( Fig. 201 ).

Remarks. Neostethynium belongs to the Anagrus group of genera. It has a 3-segmented clava as in Krokella , Neopolynemoidea , Notomymar , Paranaphoidea and Stethynium . See under Notomymar , the most similar genus, for differences between the two genera.
