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.

Abstract: A new species of Physoconops Szilady, P. (Pachyconops) weemsi, is described from Florida and Georgia. It is similar to two other species in the southeastern United States, P. floridanus Camras and P. brachyrhynchus Macquart, the main differential character being the shape of the female theca. The female thecae for all three are illustrated and a key to the three related Pachyconops species occurring in the southeastern United States is presen

The Conopid Flies of California
By Sidney Camras and Paul D. Hurd, Jr.
University of California Press, 1957
Full Text

Published over 50 years ago...but I believe this is still a very useful reference for trying to identify conopid flies in California. A key to genera appears on pg 21, and for each genus there are keys to species (those known and recognized in 1957, of course). Brief comments and range maps are given for each species.
