Cydia inquinatana §1 male
ID: Most similar to Grapholita orobana which has a longer pale mediodorsal blotch.
The long-haired black androconial scales on the upperside of the hindwing and the patch of black androconial scales in the anal region of the underside of the hindwing were very striking on dissection, not seen in any other Grapholitine I have examined, but not mentioned in the references I have seen; (there are also black andronocial scales in a subcostal band in the basal half of the forewing underside, but these are not so striking).
Male genitalia: Anteroventral margin of valva more-or-less entire; tegumen with a small nipple at the apex (which seems to become inapparent in a set specimen); aedaegus sigmoid with a scobinate mid-section with serrate carinae.
