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 ), unique shape of the phallus (see Fig. 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 ). 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 ). Desribed in Braun 1972: 78. Female genitalia. Described and illustrated in Braun 1972: 78, Fig. 39 (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 ). Larvae recorded from July, September and October; adults from August–November (Braun 1972: 78). Distribution ( Fig. 233 ). USA ( Pennsylvania , Ohio , Kentucky , Missouri , California ).
