Calycomyza enceliae Spencer

( Figs. 8, 9 , 38 )

Material examined. ARIZONA: Pima Co., Coronado National Forest, Redington Rd. , 4.iii.2017, em. 24.iii.2017, C.S. Eiseman, ex Encelia farinosa , #CSE3291, CNC940432–940434 (1³ 2♀) .

Hosts. Asteraceae : Encelia californica Nutt. (adults common on this host but no mines found (Spencer 1981; Spencer & Steyskal 1986)), E. farinosa A. Gray ex Torr. , Helianthus annuus L. ( Gates et al. 2002).

Leaf mine. ( Fig. 38 ) The mines from which we reared this species on Encelia farinosa were pale green without evident frass; vacated mines became brownish with a narrow whitish margin. They were initially linear, gradually widening to a blotch that later partly or mostly obliterated the linear portion. The larva exited through a crescentshaped slit in the upper epidermis. Gates et al. (2002) classified the mine on E. farinosa as “upper surface serpentine/blotch,” in agreement with our observations, but characterized the mine on Helianthus annuus as “upper surface serpentine.”

Puparium. ( Fig. 9 ) Brown; formed outside the mine.

Distribution. USA: * AZ, CA.
