acuta (Macrorhaphis?) Dallas 1851: 88 . [Fig. 1]
Original data: “ ♂”. “a. Congo. Presented by Sir John Richardson, M.D.” [syntype (s)] .
SYNTYPE ♂: blue-margined syntype disc; red-margined type disc; rectangular orange label “HOLOTYPUS ♂”; “ Congo / 43 56”; “2. MACRORHAPHIS ACUTA,”; “NHMUK 010592174”. Carded specimen; third to fifth left antennomeres, and fourth and fifth right antennomeres missing (Fig. 1) .
Current status: Macrorhaphis (Megarhaphis) acuta Dallas, 1851 (see Schouteden 1907: 39, for the subgeneric placement.).
Note: Walker (1867a: 129) listed a unique specimen of Dallas’s species and it is likely that Dallas just had one (especially as Dallas had stated only one measurement and noted: “Antennae pale brown, with the apex of the third and fourth joints pitchy (fifth wanting).” [emphasis ours]. Still, we cannot be certain and therefore consider the specimen a syntype, although G. Schmitz had placed a holotype male label on the specimen. Thomas (1994: 185) did not mention having seen the type under the material he examined.
