Acephana Townsend, 1916:153. Type species Masicera rubrifrons Macquart, 1847 (= Masicera rufifacies Macquart, 1847) by original designation.
Opsophana Townsend, 1916:153. Type species Masicera rufifacies Macquart, 1847, by original designation.

The diagnosis is given in the foregoing key.
Identification of species of Anagonia
Females of most species are unrecognized or cannot at present be accurately identified, although a few bear distinctive attributes that link them to the male. For males, the variability of most attributes makes it very difficult to produce a sufficiently accurate, conventional key for their identification. Some characters, too, need a little experience; e.g., whether an eye is haired or not, or whether the tibiae are paler than the femora; and some are often badly preserved. I have tried to catch any leakage over such couplets by multiple entries and the key given below will normally give the correct identification. However, complete confidence will always require the examination of the terminalia, which is required in any case for a few species.The male of A. grisea is unknown and excluded from this key (see p. 192).
