Gagne (1968) considered a larval specimen from Baccharis in Texas to be Asteromyia gutierreziae because it was similar to larvae of that species. Two other kinds of larvae based on differences in the spatulae (Figs. 14-16) have since been found. With- out pupae and adults, nothing more can be done to identify these. Because the spatulae are so different, the larvae are placed here as Asteromyia sp. 1, sp. 2, and sp. 3.
Asteromyia sp. 1, near gutiereziae Felt
This segregate is known from a single larva with a three toothed spatula (Fig. 14) similar to that found in A. gutierreziae. It was placed under A. gutierreziae in Gagne (1968). The specimen was taken from a blister leaf gall on Baccharis angustifolia (probably =salicina) collected in Kenedy Co., Texas, 20-XII-1940 by R. Runyon and found in the botanical collections of the USNM.
Asteromyia sp. 2
The larval spatula (Fig. 15) of this seg- regate has many fine serrations along the anterior edge. It is known from two speci- mens from Texas, each from a different spe- cies of Baccharis: B. pteronioides, Frijole Ranch, Guadalupe Mountains National Park, Culberson Co., Texas, X- 16- 1990, P. E. Boldt; and B. higelovii. Point of Rocks, 12 mi. W Ft. Davis, Jeff Davis Co., Texas, VI- 12- 1990, P E. Boldt.
Asteromyia sp. 3
The larval spatula of this segregate has a smooth anterior edge (Fig. 16). The single known larva was taken from a blister gall of B. salicina, Greenbelt Reservoir, 4 mi. N Clarendon, Donley Co., Texas, X-5-1988, P E. Boldt and T O. Robbins.
