In the British Isles the genus Coniopteryx is further divided into two subgenera Metaconiopteryx and Coniopteryx. The way to differentiate between the two subgenera is to look at the structure of the internal male genitalia.

The internal structure of the genitalia will allow you to identify which subgenera (the abdomen needs to be cleared). Image: Colin Plant, 1997.
