Eurhyncomyia metzi (Zumpt, 1981)

= Rhyncomyia metzi Zumpt, 1981: 487 (see taxonomic notes). Type locality: South Africa, Natal Zululand [KwaZulu-Natal], Umfalozi Game Park. Remarks: HT and PTs in NMSA.

Distribution

Afrotropical: South Africa (Fig. 39 ).

Notes

Preferred environment: no data. Recorded elevations: no data. Seasonality: recorded only in September. Behaviour and ecology: unknown. Life cycle and developmental stages: unknown. Collection methods: unknown. Illustrations and photographs: male habitus as in Fig. 40 . Male terminalia as in fig. 1 in Zumpt (1981).

Taxonomic notes: the HT and PTs of R. metzi were examined at the NMSA and their supra-squamal ridge is setulose in the posterior half, a diagnostic character that separates Eurhyncomyia (setulose) from Rhyncomya (bare). Another characteristic of Eurhyncomyia is that the aristal hairs are long and pubescent, the longest hairs slightly exceeding half the width of the post-pedicel, just as R. metzi , whereas in Rhyncomya , it is either bare or the hairs rarely exceed the width of the basal arista ( Zumpt 1958, Kurahashi and Kirk-Spriggs 2006). Based on these morphological differences, we considered that this species belongs to Eurhyncomyia genus as E. metzi comb. nov.
