Diagnosis
Note: Micropsectra contracta Reiss and M. apposita are so far separable only as females. The possible distinction between the pupae given by Säwedal, 1976a (p. 111), anal fringe with 53-55 taeniae in apposita, 69-90 in contracta, has proved unreliable: in Britain the range so far for apposita is 34-51, and for contracta is 39-60.
