Astrotischeria ambrosiaeella (CHAMbERS); DIŠKUS & PUPLESIS (2003: 427).

Material examined. 1 ♂, 1 ♀, USA: Missouri, Kirkwood, St. Louis, mining larvae on Ambrosia trifida (Asteraceae) , 13.ix.1886, ex. pupa 9.i.1890, Lord Walshingham Collection ( BMNH); 1 ♂, 1 ♀, same label but without host-plant data, [leg. Miss Murtfeldt], Lord Walshingham Collection, genitalia slide nos 28951 ♂, 28962 ♀ ( BMNH).

Diagnosis. The species belongs to the Astrotischeria trilobata group. The combination of the very distinctive, unique, horn-shaped dorsal lobes of valva (see Figs. 226–228 View FIGURES 225–229 ), unique shape of the phallus (see Fig. 229 View FIGURES 225–229 ), and a rather large but short uncus in the male genitalia distinguishes A. ambrosiaeella from all other Astrotischeria , including other members of the A. trilobata group. The fact that it feeds on Ambrosia also makes this species rather distinctive.

Male ( Fig. 225 View FIGURES 225–229 ). Forewing about 3.5–3.6 mm; wingspan about 7.5–7.7 mm. For a description see Braun Braun 1972: 77, 78.

Female. Similar to male.

Male genitalia ( Figs. 226–229 View FIGURES 225–229 ). Desribed in Braun 1972: 78.

Female genitalia. Described and illustrated in Braun 1972: 78, Fig. 39 View FIGURES 38–42 (only apophyses and prela).

Bionomics. Host plants: Ambrosia trifida L., A. artemisiifolia L., also possibly A. psilostachya DC. (Braun 1972). Leaf mine is an irregular, elongated blotch, usually between two veins (illustrated in Braun 1972: Fig. 49 View FIGURES 46–50 ). Larvae recorded from July, September and October; adults from August–November (Braun 1972: 78).

Distribution ( Fig. 233 View FIGURE 233 ). USA (Pennsylvania, Ohio, Kentucky, Missouri, California).
