Discussion.

Fainia albitarsis   is widely distributed in the Afrotropical Region. It was adequately diagnosed by Peris (1952) and redescribed by Zumpt (1958), but the illustrations of sternite 5 are incongruent between the two authors. Photographs of sternite 5 (Fig. 6F View Figure 6 ) are provided here for a proper determination of the species. The HT or STs were found to be destroyed by pests at MNHN. Additionally, the HT or STs of F. eupoda   were not found in ZMHB and we consider it missing. The specimen assigned as HT of Idia eupoda   in ZMHB is labelled as ' Pr. b. sp   Krebs // 4532 // Type (red-label) // Promontorium eupoda   Loew*'; ' Pr. b. sp   ' refers to Promontorium bonae spei   , Latin for "Cape of Good Hope’’ in South Africa and it was collected by Ludwig Krebs (1792-1844), Cape naturalist to the King of Prussia. This differs from the published type locality and collector: Inhambane, Mozambique leg. Peter, suggesting that the specimen is, in fact, not a type. Specimens from Democratic Republic of the Congo, Kenya and South Africa (see material examined section) identified by Knut Rognes, together with the description of Zumpt (1958), were used for the proper determination of this species. As the descriptions were adequate for identification, neotypes are not required for Fainia albitarsis   or Idia eupoda   . The synonymy of Idia extensa   was first published by Peris (1952), and seems reliable.

The description of Fainia kagerana   nom. nud. is an invalid nomenclatural act in terms of ICZN Article 13.1.1 because it lacks a comparative diagnosis. In addition, the descriptions and drawings of F. kagerana   nom. nud. ( Lehrer 2011: 59-61) (Fig. 13C, E, I View Figure 13 ) and F. sambura   syn. nov. ( Lehrer 2011: 63-65) (Fig. 13B, F, H View Figure 13 ) match the morphology of F. albitarsis.   On examining the F. sambura   syn. nov. HT, including the male terminalia (dissected by Lehrer) (Fig. 7 View Figure 7 ), we found that the surstyli, cerci and ventral plate exhibit the same diagnostic characters as described above (Fig. 6A, B View Figure 6 ). Careful examination of the ventral plate of the phallus revealed that the structure is articulated, with the joint located within the basi- and distiphallus membranous connection. This articulation can produce different orientations of the ventral plate in lateral and ventral views of the phallus, obscuring their typical ‘M’ shape visible in ventral view in various specimens. The phallus drawings of F. kagerana   nom. nud. ( Lehrer 2011: fig. 36D) and F. sambura   syn. nov. ( Lehrer 2011: fig. 39D) show different orientations of the ventral plate in lateral view, suggesting that they could be different species. The ‘M’ shape of the ventral plate can be clearly observed in the specimen of F. kagerana   nom. nud. (Figs 6E View Figure 6 , 7E View Figure 7 ) and partially observed in the HT of F. sambura   syn. nov. as it was partially damaged (it was crushed between the lid and wall of the microvial) (Fig. 7J View Figure 7 ). Based on this evidence, we conclude that F. sambura   is synonym of F. albitarsis   and F. kagerana   nom. nud. corresponds to F. albitarsis   .
