Extract

This species keys to eleodis Vier. in Muesebeck's revision (U.S. Dept. Agric., Misc. Pub. No. 241, p. 16, 1936) and is very similar to that species and M. aethiops Nees. The female of M. eleodis differs in having a longer ovipositor sheath (about 1.2 times as long as abdomen bevond petiole), shorter petiole (only 1.9 to 2.2 times as long as its apical width), less strongly excavated and longer propodeum (only about 1.5 times as wide as long). The female of M. aethiops differs in having a pair of small dorsal pits near the middle of the petiole (both sexes), shorter ovipositor sheath (about 0.75 times as long as abdomen beyond petiole), slightly shorter petiole (about 2.2 times as long as apical width), and completely black petiole.
