Remarks
- Systematics: Subfamily: Myzolecaniinae. Tribe: Myzolecaniini.
In order to clarify the taxonomic status and to preserve the stability of the type species of Toumeyella, a neotype was designated by Kondo & Williams (2008) for the tuliptree scale: Coccus liriodendri Gmelin (now Toumeyella liriodendri). The adult female of this scale insect was redescribed and illustrated from newly collected specimens in its native range and on its type host, the tulip tree, Liriodendron tulipifera L. (Magnoliales: Magoliaceae).
The genus Toumeyella can be diagnosed within the family by the following combination
of features: i) body of adult female convex to globular, often heavily sclerotized at maturity; ii) dorsal
setae generally sharply spinose, rarely bluntly spinose or lanceolate; iii) eyes absent; iv) sclerotic pores, tubercles, pocket-like sclerotizations and tubular ducts absent on dorsum; v) preopercular pores well developed; vi) dorsal microducts variable in structure (either unilocular or bilocular depending on the species), all of similar size, evenly scattered on dorsum; vii) anal plate setae 3–25 in number, usually less than 10 on each plate; viii) anal plates located at about 1/5 to 1/4 of body length from posterior margin; ix) sclerotized crescent around anal plates present or absent; x) stigmatic clefts shallow or absent; xi) stigmatic setae usually in 3 pairs (rarely 2 or 4, or absent in some species); xii) perivulvar and spiracular pores with 4–7 loculi, species with 5 loculi common; xiii) anterior and posterior spiracular pore bands extending in a continuous row from area around spiracles to margin; xiv) ventral tubular ducts of one type, restricted to perivulvar region and posterior abdominal segments, but not extending anteriorly in a mediolateral line, nor present elsewhere; and xv) antennae and legs greatly reduced. (Kondo & González, 2018)
- Structure: Body of adult female convex to globular, often irregular in outline, naked or with thin glassy test. Dorsum. Derm heavily sclerotized at maturity. Dorsal tubercles absent. Unilocular or bilocular microducts present; aggregations of pores rarely present. Preopercular pores present, large. Anal plates with varying number of apical, subapical and fringe setae. Hypopygial setae present. Anal ring usually with 10 (rarely 12-14) setae.
Margin. Marginal setae slender or stout, pointed or blunt but never frayed. Stigmatic setae present, 3 per stigmatic area, or completely absent. Venter. Antenna and legs greatly reduced. Legs without tibio-tarsal sclerotization. Quinquelocular pores usually present in spiracular furrows and also in vulvar and abdominal region. Tubular ducts confined to perivulvar area.
