Hu, X., Li, S., & Prokopy, R.J. 1995 Studies on the morphology and taxonomy of the male of Beesonia napiformis (Kuwana) (Coccoidea: Beesoniidae).. Israel Journal of Entomology 29: 85-91.

Notes: Sexual dimorphism is reported for the first time in species of Beesonia, occurring on plants of the Fagaceae; Beesonia brevipes is shown to be a junior synonym of B. napiformis, since the former has been described from the male form of the first-instar collections taken in China; morphological differentiation of the sexes develops at the beginning of hatching of first instars; all stages of B. dipterocarpi are compared with those of B. napiformis and reinterpreted; adult male of Mangalorea, the only other genus of the Beesoniidae.
