Species Guides
4Cleptes is a of cuckoo wasps comprising approximately 100 recognized , making it the largest genus in the Cleptinae. Members are of , exhibiting the characteristic of their . The genus has been relatively well studied in Europe and North America, though Asian faunas remain poorly documented. A 2013 revision from China recognized seventeen species, nine of which were newly described.

Identification
Distinguished from other chrysidid by the combination of small , width equal to length, and tarsal claw structure with a single submedial tooth. The metallic coloration and sculptured body surface are characteristic of the but not diagnostic at genus level. Accurate identification to requires detailed morphological examination and reference to regional revisions.
Appearance
Small to medium-sized with highly sculptured, brilliantly colored metallic bodies appearing gold, emerald, or jewel-like. Members of this are distinguished from related genera by smaller relative to size, a head approximately as wide as long, and tarsal claws bearing only one perpendicular submedial tooth.
Habitat
of Cleptes are closely tied to those of their , which include various plant-feeding sawflies. Specific microhabitat preferences are poorly documented for most species.
Distribution
Widely distributed across the Holarctic region with records from Europe, North America, and Asia. Documented presence in Denmark, Norway, and Sweden. The Chinese fauna includes at least seventeen , nine of which were described as new to science in 2013, suggesting substantial undiscovered diversity in poorly sampled regions.
Host Associations
- sawflies - of ; larvae consume or larva and then provisions
Life Cycle
are laid in nests. Larvae hatch and consume the host egg or larva while still young, then continue feeding on nest provisions. The conglobation (curling into a protective ball when threatened) has been observed in cuckoo wasps generally.
Behavior
Exhibits , entering nests to deposit . When threatened, individuals can curl into a protective ball (conglobation), a defensive mechanism also observed in pill bugs and armadillos.
Ecological Role
Acts as a regulating . As kleptoparasites of nest-provisioning , they influence energy flow in by redirecting resources from sawfly offspring to their own .

Taxonomic history
First described by Latreille in 1802. The 2013 revision of Chinese Cleptes by Wei, Rosa, and Xu represented the first systematic treatment of the for that region, increasing known Chinese from eight to seventeen.
Research status
The fauna of Cleptes in Asia remains poorly known compared to Europe and North America, with non-systematic studies limiting understanding of boundaries and distributions.
