Genus Ceronema Maskell, 1895

Type species: Ceronema banksiae Maskell, 1895

The genus Ceronema currently includes 11 species, three from Australia, three from Sri Lanka and five from Africa. The type species is C. banksiae , currently known only from Australia. Two other species in Australia, namely C. caudatum Froggatt, 1915 and C. dryandrae Fuller, 1897 , have been studied recently (Gullan & Hodgson in prep.) and it is clear that both are congeneric with C. banksiae . It is equally clear from this study that the species currently included in this genus from Africa (also probably C. fryeri Green, 1922 , C. iceryoides Green, 1922 , and C. koebeli Green, 1909 from Sri Lanka and India) are not congeneric with the type species. Of the five species from Africa currently still included in the genus, two ( C. africanum Macfie, 1913 , and C. brachystegiae Hall, 1941 ) are very similar and are clearly congeneric but show only a superficial similarity to C. banksiae ; they are here placed in a new genus, Neoceronema gen. nov. Of the other three African species, the original description of C. asparagi Brain, 1920 , is too poor for comment until it has been further studied. The remaining two species, C. gowdeyi ( Newstead, 1911) and C. mobile Brain, 1920 , are here placed in two new, monotypic genera: Illovococcus gen. nov. and Bugandacoccus gen. nov. respectively, described below.
