Eteobalea teucrii is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).
features
The moths reach a wingspan of 16 to 19 millimeters. The head is white and on the sides and back ocher to light brown. The antennae are dark brown. The last third can be indistinct lightly curled. The thorax is black. The abdomen is pale brownish ocher at the base and more silvery at the sides. It is broadly banded in dark gray in the back and on the underside. The legs are creamy white and have dark gray ligaments on the posterior tibia and the basal joints of the tarsi . Scales are only found on the distal joints. The banding is more pronounced in the middle and rear legs. The fore wings are broad and resemble Eteobalea sumptuosella . The second white costal spot is larger, however, and the pale gold spot underneath is very small. The third white costal spot is large and clearly pointed apically . Sometimes there is a pale golden stain just below it. At the apex there is a white spot that is occasionally provided with a few pale golden scales. The underside of the forewing shines brown, in the middle near the wing base there is a yellowish ocher-colored spot. The hind wings have a brownish gray sheen, they are lighter at the base. The retinaculum is yellow ocher.
In the male, the tegumen is long and almost parallel- walled . The rear bulge is V-shaped. The right brachium is straight and about three times as long as the left. It is flattened and widens distally . There is a large lobe inside at the base. The left brachium has a rather blunt apex. The blades are concave and have a rounded cucullus. The right valvella is narrow and gradually tapers to a blunt apex. On the inside, in front of the apex, there is a small, heavily sclerotized ridge. A similar ridge is located opposite on the tubular part of the aedeagus . The aedeagus is quite slender and straight. The tubular part is long and narrow, it tapers gradually and has a sharp point.
In females, the 8th segment is short and wider than it is long. The ostium is circular. The sterigma is large, spherical, and sclerotized. Curved, sclerotized ridges run towards the ostium. The ductus bursae is one and a half times as long as the corpus bursae. The corpus bursae narrows at the back and has a long, gradually tapering process. There are two large, sickle-shaped signs of different lengths.
