Key to the Afrotropical species of Phalacrotophora (subgenus Omapanta )

Note: Ph. nigrita , Ph. stuckenbergi , Ph. subnigrita and Ph. triguttata are only known in the female sex and Ph. petersoni is only known in the male sex. Reared series or pairs caught mating are required in order to provide a better key to the species that treats the two sexes separately.
