Casphalia extranea (Walker, 1869) (Figs. adults 12a–j, genitalia 29/30/31a–e, 38–39; habitats 49–50, 53, 61–62) Zaracha extranea Walker, 1869, In: Chapman T., On some lepidopterous insects from Congo, Proceedings of the natural History of Society of Glasgow, 1, pp. 225–336. TL: [DRC] Congo (depository and exact type locality are missing). Anace? herpa Druce, 1888, Proceedings of the Zoological Society of London, 1887, 670. TL: Cameroon, NHMUK. Type material examined. Holotype of Anace? herpa Druce, 1888, Female, “ Cameroon / W.

Despite numerous attempts, we could not find the original type(s) used by Walker in the original description. The NHMUK has 75 specimens of this species in their holdings, but none of them look like a potential type (based on the label data). We have contacted colleagues at the Hunterian Museum (Glasgow, Scotland), the Glasgow Museum (Glasgow, Scotland), the Bolton Museum (Greater Manchester, England) and the Hereford Museum and Art Gallery (Herefordshire, England) as they are known to house specimens of insects donated by or acquired from Thomas Algernon Chapman. However, the search was not successful and nothing that could potentially be the type specimen of Z. extranea was found. It is interesting to note that already Jacques Pierre in his 1989 work on African Sphingidae mentioned that he could not find the type specimen of Platyspinx constrigilis, a sphingid moth described by Walker in the same publication and collected by Chapman in DRC (Pierre, 1989: 118). Pierre seems to have looked only in the NHMUK and in “Glasgow”. Therefore, we consider the type specimen or specimens of the species to be lost, and in order to stabilise the nomenclature of the senior taxon of the species-complex, designate a neotype as follows:
