Nemonychidae
Nemonychidae is a small family of weevils, placed within the primitive weevil group because they have straight rather than geniculate (elbowed) antennae. They are often called pine flower weevils. As in the Anthribidae, the labrum appears as a separate segment to the clypeus, and the maxillary palps are long and projecting. Nemonychidae have all ventrites free, while Anthribidae have ventrites 1-4 connate or partially fused. Nemonychidae lack lateral carinae on the pronotum, while these are usually present, though may be short, in Anthribidae.

Time the record covers
At least 103 million years on record.
The record covers at least 154.8 Mya to 51.1 Mya. No occurrence read is dated outside 165.3 Mya to 45.9 Mya.
209 occurrences of Nemonychidae on record, most of them in the Late Jurassic. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
209 occurrences- Middle Jurassicunder 1%
- Late Jurassic72%
- Early Cretaceous22%
- Late Cretaceous4%
- Eocene2%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 51 sites for Nemonychidae, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
