Diagnosis. Belongs to Stigmella salicis group. The combination of a large speckled forewing, long stout processes of the gnathos, valva with two apical processes, and an unique set of cornuti in the phallus distinguishes S. rudis Puplesis & Robinson from all other Stigmella, including species of the S. salicis group (see Discussion).
Male (Fig. 68). Described in Puplesis & Robinson, 2000: 26. Forewing length 2.9–3.8 mm; wingspan 6.6–8.3 mm.
Female. Similar to male.
Male genitalia (Figs 69–74). Described in Puplesis & Robinson, 2000: 26. Capsule longer (300–305 µm) than wide (225–235 µm). Valva 195–205 µm long, 90–100 µm wide. Phallus (Figs 71, 73, 74) 245–265 µm long, 75– 100 µm wide; vesica with 5 wide spine-like cornuti (Figs 71, 73, 74) and an unique cluster of slender spine-like cornuti (Figs 69, 70, 72) (see Discussion).
Female genitalia (Figs 75–77). Described in Puplesis & Robinson, 2000: 26.
Bionomics. Some adults have been collected by O. Karsholt around Colletia spinosissima J. F. Gmel., Rhamnaceae, therefore, we and Karsholt assume that Colletia is possibly the host-plant of S. rudis. No leaf-mines were collected or documented. Adults fly from October to December.
Distribution (Figs 1). This species occurs in the southern Andes (Argentina and Chile) at altitudes around 200– 800 m.
