SYSTEMATICS

Lindinger, L. 1933. Beiträge zur Kenntnis der Schildläuse (Hemipt. – Homopt., Coccid.). Entomologischer Anzeiger 13: 77–166 realized when he synonymized the genera Rhizococcus, Eriococcus and Gossyparia with Nidularia that the species Gossyparia casuarinae Maskell, 1893 and Rhizococcus casuarinae Maskell, 1893 would be homonyms. As the first reviser, he apparently proposed the replacement name Nidularia chalazgamarum for Rhizococcus casuarinae and maintained Nidularia casuarinae for what Maskell considered to be Gossyparia. This action is fairly obscure in the Lindinger, L. 1933. Beiträge zur Kenntnis der Schildläuse (Hemipt. – Homopt., Coccid.). Entomologischer Anzeiger 13: 77–166 publication and Hoy, J.M. 1963. A catalogue of the Eriococcidae (Homoptera: Coccoidea) of the world. New Zealand Department of Scientific and Industrial Research Bulletin 150: 1–260 incorrectly interpreted it as an invalid replacement name.

STRUCTURE

Adult female varies in color from yellow to dark red. First instar nymphs are red and flattish, elliptical. Male unknown (see Maskell, W.M. 1892.

Transactions and Proceedings of the New Zealand Institute 24: 1–64 [dated 1891]).
