So the females penis collects the males internal sperm and from there it's somewhat conventional other than this,

Spiny structures on the penis anchor the female to the male. This tight grip allows copulation to occur for quite some time, like 40 to 70 hours

The species live in dry caves where food and nutrients are limited. "If Neotrogla males need to spend valuable resources producing their sperm packets," Scientific American , "it's likely they would be choosy about their mates ... which would help explain why the females have evolved a penis well designed to hold down reluctant mates long enough to wring out all their gifts."

Amazing how female insects act just like female humans do.
