Belongs within: Macroheterocera.
The Drepanidae are a group of moths bearing two-chambered tympanal organs on the second abdominal segment. The subfamily Drepaninae includes the hook-tip moths, so named due to the hooked ends of their forewings. The fore wing has M2 and M3 approximated at the base and the hind wing has Sc + R1 remote from Rs (Richards & Davies 1977).
Characters (from Nielsen & Common 1991): Small to medium sized; head usually smooth scaled; ocelli present or absent; chaetosemata absent; antennae filiform, lamellate or bipectinate; proboscis present and unscaled, or absent; maxillary palps minute, one-segmented or absent; labial palps short to long, porrect or upcurved; epiphysis present or absent; spurs 0-2-4, 0-2-2, 0-0-4 or 0-0-0; tarsal claws usually toothed, hind tibiae often with long scales; forewing usually broadly triangular, apex often falcate, with or without wing-locking microtrichia, often with one narrow areole, CuP absent, 1A+2A sometimes with short fork; frenulum often clubbed or absent; Sc+R1 separated from Rs at base, approximated to, or shortly fused with, Rs before or beyond end of cell, CuP absent, one or two anal veins; abdomen with paired, two-chambered tympanal organs in segment 2 with tympanum situated within a sternal component between chambers. Eggs of flat type. Larvae with ventral prolegs on segments 3 to 6 with bi- or, rarely, uniordinal crochets in a mesoseries and, usually, a small uniordinal lateroseries; anal prolegs reduced or absent, secondary setae present or absent; exposed or in rolled leaf, with end of abdomen sometimes produced and raised when resting. Pupa without dorsal spines, cremaster rudimentary, in cocoon among fallen leaves; not protruded at ecdysis.
