s. Catapterix was originally described within its own family (Sinev, 1988) but Acanthopteroctetes shares with it a number of specialised structural features including similar wing morphology (in A. unifascia) (Nielsen and Kristensen, 1996: 1255).

Distribution

Four species of Acanthoctesia in the genus Acanthopteroctetes are very localised in Western North America (Davis, 1978). Another genus, Catapterix represented by a single species comes from single sites at "Mount Karadag" and "Krasnolesie"http://translate.google.com/translate?hl=en&sl=ru&u=http://crimaniak.ihome.ru/books/records/9_2.htm&sa=X&oi=translate&resnum=9&ct=result&prev=/search%3Fq%3DCatapterix%2Bcrimaea%26hl%3Den%26sa%3DG in the Crimean Peninsula of the Ukraine

Ceanothus L. is a genus of about 50–60 species of shrubs or small trees in the buckthorn family Rhamnaceae.

, emerge in the spring. The biology of Catapterix is however unknown.

Conservation

These primitive moths must be considered high conservation priorities on the grounds that the genera are both evolutionarily highly distinctive and have very narrow ranges (Nielsen and Kristensen, 1996). Catapterix crimaea, apparently unreported more or less since its description (Zagulajev and Sinev, 1988; Zagulajev, 1992) on this basis must be one of the top priorities in Europe
Europe
