Genus Myrmecomymar Yoshimoto ( Figs. 170–178 )

Myrmecomymar Yoshimoto, 1990: 28 . Type species: Myrmecomymar masneri Yoshimoto , by original designation.

Diagnosis. Myrmecomymar belongs to the Arescon group of genera. It is distinguished from Arescon , the only other genus in the group, as follows: female wingless; toruli almost touching transverse trabecula; funicle 7- segmented ( Fig. 171 ); eye small and round, with about 15 ommatidia; ocelli absent; scutellum oval, without placoid sensilla but with two strong, erect seta instead ( Fig. 173 ); coxae, petiole and base of gastral sternum 1 strongly reticulate ( Fig. 170 ), rest of body almost smooth ( Fig. 173 ); protibial spur with inner margin comblike (as in Fig. 176 ); gastral terga 1 and 2 subequal and occupying most of gaster ( Fig.170 ). Male fully winged, with fore wing venation extending almost 2/3 wing length ( Fig. 174 ); flagellum 11-segmented, each segment with setae distinctly longer than length of segment ( Fig. 175 ); scutellum with placoid sensilla and two small, erect setae anterior to them ( Fig. 178 ); eye normal, with numeous ommatidia; ocelli present. Fore leg as in Fig. 172 and protibial spur with inner margin comblike ( Fig. 176 ). Genitalia as in Fig. 177 .

The generic limits of Myrmecomymar are widened to include the single, undescribed Australian species.This species is perhaps better placed in its own genus because it differs in several features from typical Myrmecomymar specimens, even though it bears a striking superficial resemblance to Myrmecomymar from the Western Hemisphere. In contrast to the Australian species, Myrmecomymar species from the New World have a more compact mesosoma with a rectangular mesoscutum, and the scutellum lacks both setae and placoid sensilla. More material of both sexes is needed to evaluate the differences better.

Body length. 515 µm.

Distribution. Nearctic, Neotropical, and Australian regions.
