Considered the Species type by KROMBEIN (1937), JACOT GUILLARMOD (1953) & BONI BARTALUCCI (2004), but SAUSSURE (1892) first listed M. abdominalis (GUÉRIN 1838. Females show pronotal plate with many small p bearing weak white hair; gradulus on 3 rd tergum too; 6 th tergum resembling that of M. abdominalis with only few intermingled p. Males can be acknowledged by the large subtriangular light spots on mid pronotal disc, instead of subapical stripe, a character state uniquely derived among afrotropical taxa and only shared by the new taxon M. xanthogramma from Nigeria. Some specimens have a bit darker ventral edge of the clypeus which always shows a distinct median notch. Yellow spot on mid clypeus, tip of Tsa, coxae, tips of femurs and tibiae. Apical yellow stripes also on 2 nd to 6 th terga and two very small apical spots on the sides of 2 nd to 5 th sterna. Deep notch on epipygium. Examination of female specimen labelled M. heterochroa and male with the same label do not reveal any morphological difference from other specimens but female coloration, a character state normally carrying some variability into the same population. JACOT GUILLARMOD is the authority for the sex association.
