Genus ACANTHOLECANIUM Borchsenius

Acantholecanium Borchsenius, 1949a: 339 . Type species: Ctenochiton haloxyloni Hall by monotypy and original designation.

Diagnostic characters of the adult female: Live adult female broadly oval to circular, highly convex. Margin with a series of broad, rounded protruberant rays. Slide-mounted, body lacking stigmatic clefts. Marginal setae conical. Stigmatic setae not differentiated from marginal setae. Anal cleft fairly short. Ventral tubular ducts of more than 1 type, one type with both inner and outer ductules very broad, present in a broad submarginal band from anterior to antennae to about abdominal segment II, but absent from anterior end between antennae.
