Family: Chaerilidae

Chaerilidae is a distinct scorpion family containing a single living genus, Chaerilus, distributed across South and Southeast Asia. Species within this family are generally smaller, forest-associated scorpions and are often identified using fine diagnostic characters rather than obvious external traits.

_____________________________

Genus: Chaerilus

The genus Chaerilus contains numerous species across tropical Asia, particularly within humid forest environments. Members of this genus are typically cryptic, nocturnal, and microhabitat-dependent, and many species show relatively subtle morphological differences.
