Orthochilus thomsonii ( Rolfe 1897: 66) Bytebier in Martos et al. (2014: 20)

( Fig. 5B )

Painting 6 in sketchbook 1 is Orthochilus thomsonii . This striking species was described as Eulophia thomsonii based on specimen collected by Joseph Thompson (Thomson s.n.) on his trip through Tanganyika in 1880. Since it furthermore occurs in the DR Congo, Malawi, and Zambia, it could also be expected to occur in Angola, but it is not recorded from there.
