Hypocryphalus Hopkins, 1915 Cryphalus is a large genus of tiny bark beetles, subfamily Scolytinae, tribe Cryphalini in the family Curculionidae.

In dorsal view, the head is often hidden under the pronotum, which is large, domed, and with the anterior parts covered by tubercles.

[3] A typical life cycle has been described for Cryphalus piceae which mainly infests fir trees or spruce in central and southern Europe.

They emerge in spring, mate and a monogamous pair forms a nuptial chamber under the bark of weakened or freshly dead branches, where the female lays 5–26 eggs.

However, several species are regarded as pests, causing decline of trees like fig (Ficus carica), mango (Mangifera indica) or loquat (Eriobotrya japonica).

[3] Bark beetles are often vectors of plant diseases and have special structures for carrying symbiotic fungi called mycangia.
