Amphiphala landryana Brown , new species

Fig. 5 View Figures 1–6 , 15 View Figures 12–17

Diagnosis. Superficially, A. landryana is indistinguishable from its congeners ( Fig. 3–6 View Figures 1–6 ), although the holotype female is slightly larger than many other congeners. The female genitalia of A. landryana ( Fig. 15 View Figures 12–17 ) are most similar to those of A. liatriana ( Fig. 12–14 View Figures 12–17 ), but they can be distinguished from those of the latter by the much larger sublateral sclerites of the recurved median ventral lobe (the lobe best shown in Fig. 14 View Figures 12–17 ).

Description. Head. Vertex and frons whitish yellow; [labial palpus missing]; antennal scape with pale yellow scales, flagellomeres with tan gray scales.

Thorax. Notum concolorous with head; tegula slightly darker basally. Under surface pale yellow. Forewing length 6.0 mm (n = 1); forewing ground color white, overlaid with pale yellow and pale tawny scales; median fascia broad, subtriangular, its base occupying medial 0.33 of hind margin, its truncate apex occupying medial 0.12 of costa, blackish brown, with irregular patches of silvery gray near dorsal margin; preapical fascia small, fuscous, with scattered black and rust scales; fringe concolorous with ground color. Underside gray with contrasting pale yellow ochre costal striae in postmedian and subterminal areas. Hindwing mostly whitish with limited pale gray overscaling; fringe pale yellowish gray. Underside pale yellowish gray.

Abdomen. Pale yellow dorsally, slightly paler ventrally. Male genitalia unknown. Female genitalia ( Fig. 15 View Figures 12–17 ) as described for genus, except rounded recurved process posterior to ostial plate with two long, slightly curved, sublateral sclerites; ductus bursae densely spiculate.

Type. Holotype ♀, Canada, Manitoba, Manitoba Tall Grass Prairie Preserve, Prairie Trail , 289 m, 49.0730, -967740, 18 Jul 2007, MV light, J.-F. Landry & V. Nazari, CNCLEP00040582, USNM slide 154,796 ( CNC).

Biology and distribution. This species is known only from the holotype collected in prairie habitat in southernmost Manitoba, Canada, in mid-July.

Etymology. The specific epithet is a patronym for our lifelong friend Jean-François Landry, the collector of the holotype specimen. It is considered an adjective, and the suffix “-ana” is a traditional ending for tortricid species names.
