Fletcher (1979) stated:-
The true identity of [Phalaena] pendularia Clerck, 1759, Icon. Insect. rariorum 1: pl.7, fig.5 was established by Nordström, 1941, Ent. Tidskr. 62: 127-130 and it was placed by him as a senior subjective synonym of Geometra orbicularia Hübner, , 1796, Samml. eur. Schmett. 5: pl.12, fig.60. Nordström also shewed the first available name for [Phalaena] pendularia sensu auct. to be Phalaena albipunctata Hufnagel, 1767.
Under Article 70(a) of the Code the case of a misidentified type-species should be referred to the Commission. Invalid designation of type-species: Geometra omicronaria [Denis & Schiffermüller], 1775, was designated by Boisduval, 1836, Hist. nat. Insectes (Spec. gén. Lépid.) 1: 146. In the Introduction to the volume, pages 1-154, Boisduval reviewed earlier classifications of Lepidoptera and designated as many as four different type-species for each generic name. In his `Exposè de notre mèthod', pages 155-690, no type-species designation was made for any of the genera he himself used. Under Article 69(a)(iii) of the Code the type-designation of an author is eligible for consideration if he states that it is type `... and if it is clear that he himself accepts it as the type-species.' Boisduval type-designation, although clearly stated, do not fulfil the last requirement and so are invalid.
Even though Boisduval's work was well known to lepidopterists, the type-designation contained in it have not been accepted either by Hemming or by other authors. The acceptance of Boisduval's type-species designation in the case of Cyclophora would make no difference to the generic concept, G.omicronaria [Denis & Schiffermüller] and P. albipunctata Hufnagel being currently regarded as congeneric.
