Abstract
There is disagreement as to the number of genera comprising the mannikins ( Lonchurinae). Some authors recognize two to five of the following genera: L onchura, Euodice, Padda, Spermestes and Odontospiza. Other authors have mer ged the last four taxa into the enlarged genus Lonchura. We bring together data from downy plumes (neossoptiles), nestling palate markings, begging vo calizations, agonistic behaviour, courtship postures and starch gel electro phoresis of allozymes to solve these taxonomic problems. PAUP analysis of t he combined data set indicates that Spermestes and Odontospiza belong to a monophyletic clade separate from Euodice, Padda and Lonchura. We propose me rging Odontospiza with Spermestes, which suggests an African radiation of t he group, and placing the genera Padda and Euodice in with Lonchura, which represents a mostly Australasian radiation. The genus Amadina has been trea ted by some as a mannikin (Lonchurinae) and by others as a waxbill (Estrild inae). Our data indicate that Amadina should be assigned to the estrildines rather than the lonchurines. Amadina's relatively large, mannikin-like con ical bill is a result of convergence, probably reflecting selection pressur e on bill shape associated with diet specializations.
