Remarks
- Systematics: This new genus is a definitive member of the family Coccidae based on the following combination of characters: two pairs of simple eyes, absence of hamulohalteres, presence of a square medial membranous area on the scutum, a rectangular scutellum, and a narrow neck constriction separating the head and thorax. The morphological phylogenetic analysis retrieved Rosahendersonia as sister genus to the Coccidae. When comparing this taxon to the Recent genera of Coccidae, the following combinations of characters did not allow attribution to any extant genus where adult males are known: number of eyes, absence of basisternal median ridge, absence of hamulohalteres, and the presence of ocelli. Additionally, the penial sheath is particularly short compared to extant Coccidae. This species is the first definitive occurrence of Coccidae in the Cretaceous and thus the oldest fossil of the family. . (Vea & Grimaldi, 2015)
