Anthia
Anthia is a genus of the ground beetle family from Africa and Asia. Species of Anthia can spray a jet of formic acid up to, which, if not treated, can cause blindness in animals that harass the beetles.
In general, the beetles are large, armored and fast-moving, with prominent, powerful and sharp mandibles. Some are diurnal predators in semi-arid habitats, while others are nocturnal.
The genus is one of a group of similar taxa of predatory Carabidae that has been the subject of considerable nomenclatural confusion. Several species here and elsewhere included within the genus Anthia are occasionally referred to as belonging to the non-existent genus Thermophilum, because the spelling has experienced a range of errors; the spelling that is valid under the ICZN and currently accepted is Termophilum but Thermophilum and Thermophila have been variously used in the past, as well as the misspelling "Thermophilium".
