Foldi, I. 1998a Remarques sur les Monophlebulini et les Llaveiini. Description de deux nouveaux genres (Hemiptera: Coccoidea: Margarodidae). [Remarks on the tribes Monophlebulini and Llaveiini with descriptions of two new genera (Hemiptera: Coccoidea: Margarodidae).]. Annales de la Société Entomologique de France 34(3): 309-320.

Notes: Two new genera, Gullania and Hodgsonius, are described to take two new species, G. solomonensis from the bark of an unknown species of tree in the Solomon Islands and H. cassicola from the branches of Cassia siamea in Venezuela. Their descriptions are presented within the framework of a world revision of the Margarodidae sensu Morrison, 1928. Gullania is considered to belong to the Monophlebulini and has crenulated pores, perforated cicatrices and large invaginated intersegmental lines. Hodgsonius appears to belong to the Llaveiini and has large conical spines on the perianal lobes and multilocular tubular pores with a very broad and deeply invaginated central opening. The characteristics of the tribes and the diagnostic value of the morphological characters used in the descriptions are discussed and a key to the placement of the two new genera is proposed.
