The Systematic Relationships of Dichaetoneura Johns, and Phytomyptera Rond.

Extract

In The Canadian Entomologist for January 1953 (pp. 19-30) the writer described the larval forms of Dichaetoneura leucoptera Johns. and discussed the relationship of the genus Dichaetoneura which was regarded by Johnson (1907) as closely related to Phytomyptera Rond. and later reduced to a synonym of this genus by Curran (1934). He pointed out that there are rather marked differences between the two genera in adult characters and expressed a doubt that Dichaetoneura could be classed with the Actiines as in the Manual of Myiology of Townsend (Manual of Myiology, IV.). He further remarked on the similarity between the adults of Phytomyptera and Schizactia noting briefly some of the larval characters of Schizotachina and Schizactia which are quite different from those of Dichaetoneura. In a later paper on Hyalomyodes triangulifera Loew (Can. Ent., Vol. LXXXVI, No. 3) he gave data on the larval forms of Schizotachina, Schizactia and Psalidopteryx.
