Comments: MHNCUP/ANF 212–214 are the syntypes used by Ferreira (1906) in the description of Rappia osorioi , a species named in homage to Baltasar Osório (1855-1926), a naturalist from the Museu Bocage. Ceríaco et al. (2014b) analyzed these specimens in a review of the type specimens published by Ferreira (1904 , 1906 ), confirming the species to be valid and found in northwestern Angola . Until very recently, the species had only been recorded from its type locality in Angola ( Marques et al. 2018 ), but field surveys in Serra do Pingano, Uíge Province , uncovered additional records of the species for the country (Ernst et al . 2020; LMPC pers. obs. ( Fig. 3 )).
