Type material. Female holotype , ex A. curvirostris , GHANA : Goaso , 27 March 2003 , K. P. Johnson , BDM 847 . Paratypes : 3 females , 3 males , same data as holotype . Remarks. Both sexes of M. palmeri are separated from those of the first two species by having the shorter postspiracular setae on III and V–VI and more setae on tergites I–II. Additionally, both sexes have fewer setae in each sternite II aster and more setae on sternite III, the gula, and the metasternal plate than M. masoni , and more setae on sternite VII than M. chesseri . The male of M. palmeri is further recognized by its distinctive genital sac sclerite. The lack of extreme female tergal development, both sexes with shorter postspiracular setae on III and V–VI, and the male with the unique genital sac sclerite distinguish M. palmeri from all previously known species of this genus.
