18. Depressaria depressana ( Fabricius, 1775) (Depressariidae)
Tinea depressana Fabricius, 1775: 655 . Type locality: Sweden.
BOLD:AAE7397
Palearctic distribution. Widely distributed from Europe to China and the Russian Far East.
New North American records. Canada: Québec, Gatineau , 27 Oct 2012, 1 ♂ ( CNC) ; Ontario, Port Franks , 2 Aug 2008, 1 ♂ ( CNC) . We also barcoded one female from Ontario that was found live in a garlic shipment from China ( CNC) .
Diagnosis. Externally depressana is grey with head, labial palps, mesothorax and tegulae contrastingly pale, cream-white. It resembles alienella with similarly contrasting head and thorax but the tegulae are entirely dark brown and the forewings are predominantly rufous brown with very short dark brown streaks along the veins. North American specimens of depressana have the forewings almost uniformly dark grey with a little bit of pale grey suffusion in the distal half, contrasting markedly with the pale head and thorax. The two species are easily separable on genitalia. In male depressana , the sacculus has a short, smooth recurved process protruded from its apical end about one-third the height of the valva, and the endophallus has a bundle of long, thin cornuti tightly packed together; in male alienella, the sacculus has an elongate, digitiform, spinulate, and straight apical process extended about three-quarters the height of the valva, and the endophallus is finely spinulate and without large cornuti. In female depressana , S8 is elongate-trapezoid, the antrum is more or less square with a slightly indented posterior margin, and the ductus bursae is thickly sclerotized with one loop; in female alienella, S8 is narrowly transverse, the antrum is slightly rounded, and the ductus bursae is entirely membranous with an abrupt bend at the entrance of the corpus bursae.
Larval hosts. Apiaceae : mainly wild carrot, Daucus carota , but in Europe also Carum carvi , Pimpinella , Pastinaca , Seseli and Peucedanum oreoselinum .
Note. This species is almost certainly introduced in North America. The lack of earlier records despite two revisions of the North American Depressariinae ( Clarke 1941, Hodges 1974) suggests that the introduction is recent. As in Europe ( Harper et al. 2002), it probably overwinters in the adult stage as the Québec record in late October suggests.
