Diagnosis

Male abdominal tergites yellow, T2–T4 with broad brown or black stripes, T5 and T6 with a thin black stripe expanding on the middle and fainting towards the margin ( Fig. 8A View Fig ); cercal ventral lobe (secondary clasper) partially separated from cerci with two or three very large curved black medial teeth on the internal margin; surstylus with a lateral row of strong, short prensisetae on the outer and inner margins (no medial prensisetae), the innermost one significantly long; hypandrial median process tapering ( Fig. 3C View Fig ); aedeagus hirsute with cuticular scales; inner paraphyses as long as aedeagus, with finely serrated margins ( Fig. 9 View Fig A–D). Female abdominal tergites darker than male’s ( Fig. 8B View Fig ).

Remarks

Chassagnard et al. (1997) mentioned a species, named ‘ Drosophila (Sophophora)   sp. C’, belonging to the ‘ D. montium   species group’ in Malawi with males having diffuse brown T2–T4 and pale T5 and T6. This species either belongs to one of the two species of this complex or represents a new species belonging to the complex. Elucidating its identity needs further investigation.
