Ageniella coronata
Ageniella coronata is a species of spider wasp in the family Pompilidae, first described by Banks in 1919. Like other members of the genus Ageniella, it is a small parasitoid wasp that hunts spiders to provision nests for its larval offspring. The genus is known for pronounced sexual dimorphism and ant-mimicry in females. Specific biological details for A. coronata remain poorly documented compared to better-studied congeners such as A. accepta and A. conflicta.
Auplopus
spider wasps
Auplopus is a large genus of small spider wasps in the family Pompilidae, distributed worldwide except Antarctica. Females construct distinctive barrel-shaped mud nests, often inside pre-existing cavities such as abandoned nests of other wasps, hollows in wood, or rock crevices. They hunt spiders, paralyze them with venom, and amputate the legs before transporting the prey to their nests. The wasps provision each mud cell with one or more paralyzed spiders, lay a single egg on the final victim, and seal the cell. Auplopus species are solitary and non-aggressive, with most activity occurring from May to October.
Caliadurgus
Caliadurgus is a genus of medium-sized spider wasps in the family Pompilidae, subfamily Pepsinae. The genus was established by Pate in 1946 as a replacement for the preoccupied name Calicurgus. These wasps are known for hunting orb-weaving spiders (Araneidae) and long-jawed orb weavers (Tetragnathidae) to provision nests for their larvae. The genus has a Holarctic and Neotropical distribution, with species recorded across North America, Europe, and South America.
Caliadurgus fasciatellus
Blotchwing Spider Wasp
Caliadurgus fasciatellus is a small spider wasp in the family Pompilidae, subfamily Pepsinae. It ranges from Western Europe to the Far East of Asia. The species hunts orb-weaving spiders, paralyzes them, and provisions underground burrows for its larval offspring. It was historically confused with Priocnemis hyalinata due to taxonomic errors regarding type species designations.
Cryptocheilus
spider wasps
Cryptocheilus is a genus of spider wasps in the subfamily Pepsinae, occurring primarily in warm regions worldwide. Females construct multicellular nests in pre-existing cavities, provisioning each cell with a paralyzed spider as food for their larvae. The genus includes approximately 24 species in Europe, 6 in North America, and 2 recently described from the Neotropics. Several Australasian species formerly placed here have been transferred to the revived genus Heterodontonyx based on phylogenetic evidence.
Episyronini
Episyronini is a tribe of spider wasps within the family Pompilidae. Members are solitary wasps that hunt spiders to provision nests for their larvae. The tribe is distinguished by morphological features of the mesosoma and wing venation. Episyronini species are primarily found in the Americas, with some extending into other regions. They represent a well-supported monophyletic group within the subfamily Pepsinae.
Hemipepsis
tarantula hawks, Old and New World Tarantula-hawk Wasps
Hemipepsis is a genus of large spider wasps in the family Pompilidae, commonly known as tarantula hawks. The genus contains approximately 180 species distributed throughout tropical and subtropical regions worldwide, with significant diversity in Africa, Asia, and the Americas. Hemipepsis wasps are distinguished from the related genus Pepsis by subtle differences in wing venation patterns. In South Africa, Hemipepsis wasps serve as exclusive pollinators for 18 plant species across three families (Apocynaceae, Orchidaceae, and Asparagaceae subfamily Scilloodeae). The genus has been extensively studied for its complex male territorial behavior, particularly in the North American species H. ustulata.
Pompilidae
Spider Wasps, Spider-hunting Wasps, Pompilid Wasps
Spider wasps in the family Pompilidae are solitary, stinging wasps that hunt spiders to provision nests for their larvae. The family contains approximately 5,000 described species in six subfamilies, distributed worldwide. Most species capture and paralyze spiders using venom, then deposit them in burrows or cavities where a single egg is laid on each victim. Females of the genus Auplopus construct distinctive free-standing mud cells, while most other genera excavate burrows in soil or use pre-existing cavities. Members of the subfamily Ceropalinae are kleptoparasites, laying eggs in the nests of other pompilids or acting as ectoparasitoids of living spiders rather than building their own nests.
