Abstract. Procecidochares kristineae Goeden, n. sp., and P. lisae Goeden, n. sp.,
are described and figured as adults and distinguished from each other by their wing
patterns, chaetotaxy, and genal color and by these and additional characters from all other
North American congeners. Sexually dimorphic wing patterns in P. lisae are reported for
the first time from this genus. First through third-instar larvae and puparia also are de-
scribed and figured for both species, but few morphological differences were found. Pro-
cecidochares kristineae and P. lisae are strictly monophagous tephritid flies forming ax-
illary bud galls on branches of the native, shrubby, xerophytic ragweeds. Ambrosia du-
mosa (Gray) Payne and A. eriocentra (Gray) Payne (Asteraceae), respectively. Both are
circumnatal species that overwinter as first instars within incipient galls in southern Cal-
ifornia. Further gall and larval development and host-plant regrowth and reproduction are
stimulated concurrently by winter rainfall. Reproduction by P. kristineae is rarely biennial,
usually univoltine or bivoltine, and rarely trivoltine, depending on local yearly rainfall
patterns; whereas, P. lisae usually is univoltine or bivoltine.

be readily separated on the basis of their
wing patterns and the color of the genal
spot as described in the partial key provided
above. The pterostigmal character is shared
only by P. flavipes, P. kristineae, and P.
lisae, with P. flavipes separated by its pos-
session of two pairs of orbital setae. The
basal and discal bands are joined only in
the wings of P. kristineae, P. lisae, and P.
