( Figs 11–14 View FIGURES 11 – 14 )
Type material: Holotype male, GHANA: Eastern Region, Subri stream, North of Kibi, 6.xi.1993, NUFUproject ( ZMUN). Paratypes: 3 males, as holotype; 1 male, Volta Region, Agumatsa waterfalls, Wli, 4–14.iii.1993, NUFUproject ( ZMUN); 3 males, Volta Region, Agumatsa waterfalls, Wli, 11–20.xi.1993, NUFUproject ( ZMUN); 7 males, Central Region, Kakum, 31.x.–8.xi.1994, NUFUproject ( ZMUN); 2 males, Central Region, Kakum, 8–15.xi.1994, NUFUproject ( ZMUN); 2 males, Western Region, Ankasa game production Reserve, 31.iii.1993, NUFUproject ( ZMUN).
Etymology: Named after the country of origin.
Diagnostic characters: The male groups with M. camerounensis Matile and M. securiculata Matile in having a simple gonostylus with thickened base. It can be separated from M. camerounensis in having the lobes of tergite 9 evenly setose, and from M. securiculata in having a comparatively short gonostylus. The species is smaller, and has a slightly darker appearance than other species in the genus.
