Bactrocera (Gymnodacus) mesomelas (Bezzi)
Dacus mesomelas Bezzi, 1908a: 386 Other synonyms: White (2006: 144)
Material. CAMEROON: 1 male, Bafoussam, 28.vii.1982, ex Psidium guajava, G.J. Steck (TAU); 2 male, 3 female, Essé, 23.ix.2004, ex Psidium guajava, F.X. Ndzana Abanda (MRAC).
Remarks. White (2006) reported examining a long series of reared specimens from Democratic Republic of Congo (1935), labelled “Fruits de Perinari”, which was assumed to be a misspelling of Parinari, a genus of Chrysobalanaceae . This genus also lends its name to a widespread African forest vegetation type (e.g. Karlowski 2006) and the specimens may therefore have been reared from an unidentified fruit in “ Parinari forest”, assuming such a vegetation type was recognised in 1935. White (2006) also examined a very badly damaged teneral male that was apparently reared from guava ( Psidium guajava, Myrtaceae) in Cameroon in 1982 but disregarded the host data on the assumption it represented a labelling error (data given on CD only). Further specimens have now been reared from guava in Cameroon thus confirming guava as a true host; the association with Parinari should now be regarded as doubtful.
