Sergiolus angustus
Sergiolus angustus is a ground spider in the family Gnaphosidae, native to western North America. Like other members of its genus, it exhibits bold coloration that may represent mimicry of velvet ants (Mutillidae). The species is medium-sized, diurnal, and nomadic, actively hunting rather than building webs to capture prey. It constructs silk retreats for molting, egg guarding, and overwintering.

Sergiolus minutus is a species of ground spider in the family Gnaphosidae. It belongs to a genus noted for bold coloration and potential mimicry of velvet ants (Mutillidae). As with other Sergiolus species, it is a nomadic hunter that does not construct webs for prey capture. The species has been recorded from the Caribbean region including Cuba and Jamaica, as well as the United States.
