Valdivian Forest Moths (Lepidoptera: Andesianidae)
Valdivian forest moths, family Andesianidae, total only 3 known species from southern Andean forest zones of Argentina and Chile. The family is the most primitive of the Monotrysian moths, in its own monobasic superfamily Andesianoidea, and in the section Nepticulina. Adults are robust and of medium size (27 to 61mm wingspan), with head scaling roughened; haustellum very short (with vestigial mandibles present); labial palpi elongated (with elongated 2nd segment); maxillary palpi 5-segmented (unfolded); and antennae bipectinate in males (filiform in females). Wing maculation is lustrous gray with numerous darker vertical striations, plus some dark spotting. Wing venation is heteroneurous but somewhat primitive with added veins. Adults apparently are nocturnal (possibly crepuscular), mainly in Nothofagus forests. Biologies are unknown, but larvae are likely to be stem borers.
