NOTOMYMAR Doutt & Yoshimoto, 1970

( Figs 211–217)

Notomymar Doutt & Yoshimoto, 1970: 293 . Type species: Notomymar aptenosoma Doutt & Yoshimoto, 1970 , by original designation.

Diagnosis. Face with faint subantennal sulcus ventral to each torulus ( Fig. 215a); toruli separated by their own height from transverse trabecula; mandibles each with 2 teeth, the dorsal one wide and apically serrated, the teeth overlapping medially when mandibles closed ( Fig. 215a); funicle 6-segmented; clava 3-segmented ( Figs 212, 216); both sexes apparently apterous ( Fig. 213), brachypterous or macropterous ( Fig. 217). Male flagellum 9-segmented, with the apical two segments widely joined.

Remarks. Notomymar belongs to the Anagrus group of genera. The other genera in the group with a 3-segmented clava are Krokella , Neopolynemoidea , Neostethynium , Paranaphoidea (Idiocentrus) and Stethynium . Two species are illustrated: the apparently wingless species from South Georgia Island, and a fully winged species from mainland South America. At high elevations (4000 m) in Ecuador another, almost wingless, described species ( Yoshimoto 1990) has a similar mandible to the type species. Macropterous specimens of Notomymar appear to be most similar to species of Neostethynium so Notomymar may eventually be shown to be a synonym of Neostethynium . The only differences that distinguish Neostethynium from Notomymar (either winged or wingless) appear to be the size and position of the ocelli, the head shape in lateral view, and the presence or absence of a transoccipital sulcus. In Neostethynium the ocelli are large and close together and the vertex is flat and at right angle to face, and there is no transoccipital sulcus, whereas in Notomymar the ocelli are small and far apart ( Figs 211, 215b), the vertex is more convex and not at a sharp right angle with the face, and there is a distinct transoccipital sulcus ( Fig. 215b). The generic limits are unclear, partly because it is so difficult to determine relationships of macropterous species, with their various reductions in the mesosoma.

Neotropical hosts. Unknown.
