Calycobathra acarpa is a butterfly from the family of Chrysopeleiidae .
features
The moths reach a wingspan of 11 to 12 millimeters. The head is pale ocher. Thorax and tegulae are pale ocher and darker in front. The forewings have a pale ocher to greyish ocher basic color. There is a small, dark brown line on the anal fold. A similar line is at 3/5 of the fore wing length in the middle of the wing. Indistinct longitudinal lines run along the wing veins, which are somewhat more pronounced in the apical area. The fringed scales are ocher gray. The hind wings are gray and have ocher-gray fringed scales. The abdomen has a gray sheen and an ocher tuft of anus . In the females the seventh segment is completely black ventrally .
In the males the uncus is short and strongly curved. The blades are slender, strongly curved distally inward and tapered towards the apex. The apex is widened and spatulate. It has thick bristles on the inside. Three long and curved dorsal bristles extend from the base to half the length of the valve. The bristles on the outside are hair-like. The praises of the vinculum are triangular. The aedeagus is long and slender and slightly S-shaped. At the apex there is a very long and a short tooth.
In females, the slit-shaped bulge of the seventh sternite is bottle-shaped. It is sclerotized in front . The fold of the sixth sternite is almost rounded. The ostium is surrounded by a ring-shaped reinforcement of sclerotized bulges, which are connected to a large, circular, intricate genital plate. The center is triangular. The lateral parts of the genital plate have a reticulate structure and merge into a protrusion with a similar structure. They are connected at the back to the upper part of the triangular plate and partially enclose the slot-shaped bulge. The ductus bursae runs in two turns and has a sclerotized, elongated stiffening band. The antrum is long and straight. It has two thick, trap-like rows of hair on the inside. The corpus bursae is rounded and has a reticulate surface. The two Signa are small and have a circular base. There is a small stinger in the center of the base, and there is occasionally another, smaller stinger. Calycobathra acarpa differs from Calycobathra calligoni and Calycobathra variapenella by the circular genital plate and the long, narrow antrum.
