Abstract Heleanna melanomochla (Meyrick )ef, which larva feeds on mango in Taiwan, is
redescribed. The genitalia and immature stages are illustrat efdor the firs ttime.
Key words Tortricidae, Hbleanna melanomochla (Meyrick )im,mature stages, insect pest of
rnango, Taiwan.
Higleanna melanomochla (Meyrick )was described by E, Meyrick in 1936, based on sorne
specimens bred from larvae feeding on mango in Taiwan. Until now, this species has
been litt lestudied, and the genitali aand immature stages have not been figured.
Recently ,I collected the larvae'* in Taiwan and got some emerged meths. In the
following lines the redescription of the moth is given, with the illustratio nofs adult,
larva
genitalia , and pupa.

Remarks. This moth is superficially similar to Hl Pldysalo d(eMseyrick 1,910), but differs
from it in having wide dorsal concavity of tegumen, thick socius in male genitalia ,and
