Anteon

Jurine, 1807

Anteon is the largest in the Anteoninae of the , comprising approximately 464 described with a distribution. Species in this genus are of ( and Eurymelidae). Females possess a protarsus used to capture and immobilize leafhoppers for and feeding. The genus exhibits extreme , which has historically complicated taxonomic work and led to many species being described from single sexes.

Identification

Females are distinguished from other by the (-like) protarsus, a characteristic of the Anteoninae. The are modified foretarsal structures used to grasp . Extreme means males and females may appear morphologically distinct; has proven effective for confirming sexual associations and delimitation. Identification to species level requires specialized and examination of detailed morphological characters.

Habitat

Forest and grassland ; specimens have been collected using in various vegetation including forested areas and grasslands. Specific collection localities include elevations of 1595–1683 m in Yunnan Province, China, and corn fields in Tucumán Province, Argentina.

Distribution

Life Cycle

The develops within a larval sac located laterally on the intersegmental of the 's , distinguishing Anteon from Gonatopodinae which have abdominal larval sacs. The forms a in a substrate such as sand, from which the emerges. Laboratory rearing has demonstrated successful development from to adult.

Behavior

Females use their protarsus to capture and immobilize , enabling and feeding on the host. The exhibits extreme , with males and females showing marked morphological differences that have historically impeded taxonomic work.

Ecological Role

Human Relevance

Potential agents for pests in agricultural systems, particularly for management.

Taxonomic Challenges

Extreme has resulted in many Anteon being described based on a single sex. has proven to be a potent tool for confirming sexual associations and resolving taxonomic challenges in this . A 2024 study employing integrated ( + DNA barcoding) on Chinese specimens described five new species and confirmed sexual associations for six species, leading to one synonymy.

Reproduction

At least some exhibit thelytokous (female-producing) . In laboratory conditions, females of A. pilicorne exposed to for seven days produced offspring, with most being parthenogenetic.
