Clistopyga

Gravenhorst, 1829

Clistopyga is a of in the Pimplinae, first described by Gravenhorst in 1829. The genus contains approximately 50 described , with the majority distributed in the Neotropical region. Species are characterized by specialized for parasitizing , including modified used for clinging to and felting spider to seal nest openings. Several species groups have been established within the genus based on morphological and distributional patterns.

Identification

Members of Clistopyga can be distinguished from other Pimplinae by their association with and corresponding morphological . The typically retains serrations despite reduction in overall complexity compared to other . Some exhibit highly modified metasomal tergites and distinctive color patterns. The genus Afroanomalia was synonymized with Clistopyga in 2024.

Habitat

Tropical and subtropical forests, particularly rain forests. The Andean-Amazonian interface in Peru has been specifically documented as for at least one .

Distribution

Primarily Neotropical, with approximately 30 of 50 described occurring in this region. Range extends into the southern Nearctic region (northern Mexico) and includes the Yucatán Peninsula. Some species have been recorded from Belize, Brazil, Colombia, Venezuela, and Peru. Distribution records also exist from Denmark, Norway, and Sweden.

Host Associations

spiders - primary ; specific include Salticidae
Telamonia dimidiata - for at least one described
ants - possible modelsuggested as potential target based on coloration patterns in some

Behavior

Females use their to cling to as the spider attempts to escape. A documented behavioral involves using the ovipositor to felt spider , sealing openings in silken spider nests in a manner comparable to needle felting. This is hypothesized to protect developing offspring. Some exhibit , with two possible explanations proposed for bizarre metasomal and coloration in at least one species.

Ecological Role

of . The sealing of spider nests after may influence spider and nest availability in forest .
