Pseudostigmatinae

Pseudostigmatinae is a subfamily of beetles within the family Cerambycidae, commonly known as longhorn beetles. This subfamily is characterized by their distinctive antennae, which are clubbed at the tip and have a distinctive "pseudo-stigma" or knob-like structure. This feature is the basis for the subfamily's name, which translates to "false stigma." Pseudostigmatinae is further divided into several tribes, including Pseudostigmini, which includes the genus Pseudostigma, and Xystrocerini, which includes the genus Xystrocera.

The larvae of Pseudostigmatinae are known for their unique feeding habits. They are xylophagous, meaning they feed on wood, and are often found in the galleries they create within the wood of their host trees. This subfamily is found in various habitats, including forests, woodlands, and even urban areas, where they can be found feeding on dead or dying trees.

Pseudostigmatinae is a diverse subfamily, with over 100 species described worldwide. They are found in various regions, including North America, South America, Africa, and Asia. Despite their diversity, Pseudostigmatinae are not well-studied, and much remains unknown about their biology and ecology. However, their distinctive appearance and unique feeding habits make them an interesting group of beetles for further study.
