Dioptrornis Fischeri Reichenow, 1884a: 53 .

Now: Melaenornis fischeri fischeri (Reichenow, 1884) . See Mayr et al. (1986: 303).

Syntype: ZMB 27025 (B 18661, Fischer no. 912), skin, former mount, female, collected at “Gross Aruscha”, 10.07.[18]83 .

Syntype: ZMH 6916 (Fischer no. 931), skin, former mount, male, collected at “Gr[oss] Aruscha”, [15.07.]1883 .

Type locality: “ Maeru Berg (Massai)” [ Mt Meru , Arusha Region, Tanzania], from the original description as well as locality of the syntypes .

Remarks: In the original description no type was chosen, and there were no inventory numbers for specimens provided, but measurements for one specimen and the locality “Maeru-Berg, Massai” were given. Fischer (1884) listed four (nos. 912, 931, 826, 820) from “Gross-Aruscha” and “Naiwascha” for this species. As the description matches both sexes, and with both specimens from “Gross Aruscha” collected near Mount Meru (no specimens of this species are traceable from Mount Meru itself), ZMH 6916 and ZMB 27025 are regarded as syntypes for this species. The juvenile specimens Fischer nos. 826 [see Fischer 1884; ZMB 27437 (female, “Naiwascha”, 27.05.1883), no. 820 (see Fischer 1884), and possibly ZMH 8406 (“Naiwascha”, 1883)] were all collected at Lake Naivasha and are therefore not regarded as syntypes. Bolau (1898) incorrectly listed ZMH 6919 and ZMH 8406 as the type specimens.
