Crinopteryx familiella is the only species of the genus Crinopteryx , which in turn is the only one in the butterfly family Crinopterygidae . The animals are only known from the south of France and Sicily.
features
The small moths have a fore wing length of 3 to 3.5 millimeters. Her head is rough everywhere and has hair-like (piliform) scales . The compound eyes are somewhat regressed. The antennae are about 60% the length of the forewings. They are easily scaled. The flagellum is thread-like. The labrum and the pilifer are regressed. The tiny mandibles are about a third the length of the first segment of the maxillary palps . The short house lumbar is scaly and about half as wide as the head. The maxillary palps are four to five members. They are strongly curved and have a tiny tip link that is sometimes missing. The labial palps are tripartite and have upright bristles from the second segment. The lateral processes of the lateral cervical sclerite are broadly triangular. The anterior margin of the anteromedial process (APM) of the metafurca is wide and flared. The dorsal apophysis is moderately short and has no diverting arms. The forewings are narrow. The radial vein has five, the median vein has three separate branches. The base of the median vein is simple on both pairs of wings and lies within the cell. The wing veins 1A + 2A are completely fused and have no basal bifurcation. In the male, the retinaculum is relatively long, triangular, and the costal fold extends below the base of the Sc artery. The hind wings are almost the same width as the fore wings. On them, the median vein has three separate branches. The frenulum of the males consists of a single, large bristle, which is surrounded by several small, costal sets. The females have a number of much smaller, undifferentiated costal sets. The anterior rails ( tibia ) of the legs have none, those of the middle two and those of the posterior four spurs. An epiphysis is formed. The rearward (caudal) edge of the sternum 2a is W-shaped. The rear edge of the seventh sternum is truncated in females.
In the male genitalia, the uncus is indistinct and has a broad, flat, double-lobed caudal margin. The vinculum is broadly V-shaped. The valves have a single, large subapical spur. The Juxta is broadly angled. The aedeagus is short, relatively compact, and has numerous short cornuti. In females, the ovipositor has a flattened, laterally lobed tip, similar to that of the mini sac moths (Incurvariidae). The copular bursa is completely membranous and has no signa .
The caterpillars are little known in their morphology. They have a cylindrical body that is 3.4 to 4.0 millimeters long. The mouthparts are directed forward (prognath). The head bears six pairs of stemmata . The thoracic legs are well developed, the hips are separate. The abdominal bones are receded, hook rings are formed on the third to sixth abdomen segment. They are arranged in two simple rows. The pusher is missing.
Way of life
Little is known about the eggs. The females lay them individually in plant tissue. The caterpillars build elongated, 3.5 to 4.0 millimeters long and 1.5 to 2.0 millimeters wide, almost cylindrical quivers made of leaf epidermis. The caterpillars feed on rock roses ( Cistus ). Before eating, the caterpillar attaches its quiver to the underside of a leaf and crawls in through a small opening to mine on the leaf, similar to the caterpillars of the mini-sac carrier (Coleophoridae). The doll reaches a maximum length of 3.5 millimeters. On the terga of the second to eighth abdominal segment there is a large area of tiny, scattered spines.
Taxonomy and systematics
Because of the flattened ovipositor, Crinopteryx familiella resembles the mini sac moths. The unambiguous autapomorphies , which include a way of life similar to that of the mini-sack carrier, the elongated, cylindrical quiver of the caterpillars, the angled juxta and the single, large spur on the valves of the males, justify the classification in a separate family.
