Habitat
in this occupy a range of terrestrial including forests, scrublands, and disturbed areas. They are ground-dwelling or low vegetation hunters. Teminius hirsutus has been recorded from sea level to mid-elevations in its broad Neotropical range.
Distribution
The is distributed across the Americas. Teminius affinis occurs in the United States and Mexico. Teminius agalenoides is found in Paraguay and Argentina. Teminius hirsutus ranges from Mexico through Central America to Venezuela and throughout the Caribbean. Teminius insularis has the broadest distribution, occurring in the United States, the Greater Antilles, and South America to Argentina.

Taxonomic History
The was established by Eugen von Keyserling in 1887. The number of included has remained stable, with four species currently recognized following revisions. The genus name has been consistently placed in Miturgidae, though -level relationships within the clade have undergone revision in recent molecular phylogenetic studies.
Species Diversity
The four recognized show substantial geographic range variation, with T. insularis and T. hirsutus having broad Neotropical distributions while T. affinis and T. agalenoides have more restricted ranges. No new species have been described since the mid-20th century, suggesting either genuine low diversity or lack of recent taxonomic attention.
