Placonotus is a genus of beetles in the family Laemophloeidae. There are 40 currently recognized species, known from all continents except Antarctica. Placonotus species are small (~2mm), elongate, flattened beetles, characterized by long filiform antennae, presence of a frontoclypeal suture, open anterior coxal cavities, and broadly rounded intercoxal process of abdominal ventrite III. Males have the 8th abdominal segment modified to form claspers used during mating.[1] Adults and larvae are found under dead bark, where they feed on fungi. Currently recognized species are:
- Placonotus africanus Lefkovitch
- Placonotus arizonensis Thomas
- Placonotus bolivari Grouvelle
- Placonotus debanus Mukhopadhyay

- Placonotus ealaensis Lefkovitch
- Placonotus embuensis Thomas
- Placonotus exornatus Grouvelle
- Placonotus falinorum Thomas
- Placonotus gladiator Thomas

- Placonotus patruelis Thomas
- Placonotus planifrons Thomas
- Placonotus politissimus Wollaston
- Placonotus proximus Grouvelle
- Placonotus pseudomodestus Thomas
- Placonotus pseudoproximus Mukhopadhyay & Sen Gupta
- Placonotus rigidus Olliff

- Placonotus subtruncatus Lefkovitch
- Placonotus tastus Lefkovitch
- Placonotus testaceus Fabricius

The genus has been treated taxonomically for several geographical regions: the New World;[1] Africa;[2] Europe;[3] and India.[4] The Asian, Pacific, and Australian faunas have not been worked and there are probably many unassigned and undescribed species.
