Epirhyssa is a genus of wasps belonging to the family Ichneumonidae. The highest concentration of the Epirhyssa species is found within the Oriental region.

The species is fairly small compared to other species, and takes on a Tan color that can range to a sienna color. The small bug is long and skinny, and possesses wings that can range from 6.0 to 8.0 millimeters. Although typically spotted within the Tan or Sienna color range, certain members of the genus have an orange like color tone, that colors their wings as well. Similar in appearance to other members of the Ichneumonidae family, these insects are unique in appearance, boasting a curved abdomen, with several long tail-like protrusions coming out through a hole in the back of the abdomen.

Although current research on the Rhyssinae is very minimal, Since 2011, Robert Copeland and coordinators in the International Centre of Insect Physiology and Ecology in Nairobi have been running an trap collecting programme. With the hopes of being able to learn about the species in the future, the species still remains rather unknown as of late 2025.

The species of this genus are found across areas of Africa, including:

• Central African Republic, Cameroon, Democratic Republic of Congo, Madagascar, Nigeria, South Africa, Uganda.

Some other notable locations include:

• The Oriental region
• Western coast of South America
• North America
