Gavrilov-Zimin, I.A., & Gapon, D.A. 2016 New Afrotropical scale insect pests (Homoptera: Coccinea) under glass in St Petersburg, Russia. Zoosystematica Rossica 25(2): 233–238

Notes: Two Afrotropical scale insect species, Trochiscococcus speciosus (De Lotto, 1961) and Ripersiella aloes (Williams et Pellizzari, 1997), are recorded for the first time in Russia, St Petersburg, under glass on the roots of Gasteria sp. (Asphodelaceae). The first species is morphologically described and illustrated by a standard total coccidological figure and by the photograph; a study of the reproductive biology of this species revealed an obligate ovoviviparity, parthenogenesis (thelytoky) and the chromosomal number 2n=10. The quarantine status for both species is advised on the territory of Russia and neighboring countries.
