Williams, M.L., & Kondo, T. 2008 Status and current composition of the soft scale insect genus Toumeyella (Hemiptera: Coccidae).. Proceedings of the XI International Symposium on Scale Insect Studies, Oeiras, Portugal, 24-27 September 2007. ISA Press Lisbon, Portugal 322 pp.

Notes: The genus Toumeyella is in the subfamily Myzolecaniinae of the Coccidae, and is part of the Toumeyella-group, which is composed of about 50 species and includes the genera Akermes, Cyclolecanium, Megasaissetia, Neolecanium, Octolecanium, Pseudophilippia, and Toumeyella. The genus Toumeyella is only known from the New World, from North America southwards to Central and South America. It is well represented in North America north of Mexico, with 11 described species. Two species are known from Brazil, two from Mexico, and one species from Cuba. Studies of various life stages of the Toumeyella-group by the authors have indicated several needed changes in the composition of this complex of species and have identified additional undescribed species of Toumeyella from North and Central America.
