Diastatomma multilineatum Fraser, 1949
Type locality: Luigunda [ass. Lingunda], DRC
Male is similar to widely co-occurring D. selysi by (a) pale stripes on thorax narrow, on black background, with antehumeral and metepisternal stripes complete; (b) all veins including costa dark. However, differs by (1) black on fronto-clypeal suture wide on both sides of suture and broadly fused with black on lower postclypeus; (2) posterior hamule deeply, rather than weakly incised, and its border pointed anteriorly; (3) two dorsal black stripes usually interrupt apical pale ring on S2, but basal pale ring on S3 complete; (4) inner branch of cercus almost perpendicular to cercus axis (rather than slanted backwards), angle between them about 80º (rather than 60º), branch more parallel-sided and square-cut at end.

Streams shaded by forest. Mostly with a sandy but often also gravelly bottom, blackwater and probably coarse detritus. From 300 to 600 m above sea level, but mostly around 400.
