Diagnosis
Fore wing length 2.45–2.52 × (2.51) width. Male genitalia: harpe finger-shaped apicoventrally in ventral, lateral and dorsal view; harpe/gvc index 0.51; ventromedial margins of harpes not touching at distoventral margin of gvc, ventromedial margin of harpe concave in basal two thirds, convex and harpes overlapping in apical third; ventral margin of harpe straight in basal half and straight and oriented distoventrally in apical half, with distinct emargination at its middle, dorsal margin concave in basal half, straight and oriented distoventrally in apical half, lateral margin slightly convex in basal half and concave in apical half; aedeagus + gonossiculus with at least two distinct digital teeth, oriented ventrolaterally.
Etymology
The species is named in honour of Chief Mangi Meli (1866–1900), who was the leader of the WaChagga and fought against German colonialists and was brutally executed in 1900.

Female
Unknown.
Variation
Some paratypes, for example, ZFMK-HYM-00037041 and ZFMK-HYM-00037042, are distinctly darker, especially in the antennae and the distal end of the stigmal vein.
Biology
Host unknown, specimens collected with coloured pan trap.
Distribution
Afrotropical: Tanzania.
Remarks
Comparison with similar species
Aphanogmus mangimelii sp. nov. can be distinguished from all other treated species by the weakly sclerotized and finger-shaped harpe, the distinct emargination at the middle of the ventral margin of the harpe, the overlapping apical thirds of the harpes, the ventrolaterally oriented digital teeth of the aedeagus + gonossiculus, and the relatively high harpe/gvc index (0.51).
Condition of type material
In the holotype, the left F7 to F9 are missing. The distal flagellomeres of the right flagellum are deformed. The posterior half of the metasoma is deformed, thus the body length measurement is not precise. Paratypes SMNS-HYM-T00779 and SMNS-HYM-T00780 were used in an unsuccessful DNA barcoding attempt, i.e., had been put in lysis buffer for non-destructive DNA extraction, and look more transparent.
