Remarks. Four Calycomyza species are leaf miners of Hyptis: Calycomyza arcuata, Calycomyza hyptidis Spencer, Calycomyza hyptisicola Spencer and Calycomyza menthae Spencer (Benavent-Corai et al. 2005). Larvae of C. hyptisicola and C. menthae forming blotch-like mines, but these species are distinguishable by the male genitalia, especially in the form of aedeagus.
