There are more recent Myopa references for other parts of the world, but I searched through all the published names under Myopa using the "Nomeclator" at Systema Dipteratorum, and found no nearctic taxa there that are missing from this work.

ABSTRACT - Parasites of adult bees are almost exclusively flies and the most important of them are conopids. This note registers for the first time the association of species of Physocephala (Diptera: Conopidae) with Centris (Heterocentris) analis (Fabricius). From 26 females and nine males of the host species found dead inside trap-nests on the campus of the University of São Paulo, Ribeirão Preto, Brazil, 35 parasitoids were obtained belonging to nine species of Physocephala.
