Taxonomic changes in Ichneumonoidea (Hymenoptera), and notes on certain type specimens.

Area of Science:

• Entomology
• Systematic Entomology
• Hymenoptera Taxonomy

Background:

• The Ichneumonidae family, a diverse group of parasitic wasps, requires ongoing taxonomic revision to accurately reflect evolutionary relationships.
• Accurate classification is crucial for understanding ecological roles and biodiversity.

Purpose of the Study:

• To revise the taxonomy of several genera within the Ichneumonidae family.
• To establish new taxonomic synonymies and combinations based on morphological and literature analysis.
• To provide new host records for two Ichneumoninae genera.

Main Methods:

• Comparative morphological analysis of type specimens.
• Literature review and historical taxonomic data assessment.
• Designation of lectotypes for selected species.
• Recording host-parasite associations through rearing.

Main Results:

• Seven new synonymies are established, including Acrodactyla iliensis with Acrodactyla lachryma and Euceros with Lentocerus.
• Eight new species combinations are proposed for genera such as Aleiodes, Cyclophatnus, and Zatypota.
• Netelia morleyi is reclassified from subgenus Netelia to Paropheltes.
• One new replacement name, Aleiodes philippinensis, is proposed.
• Lectotypes are designated for eight species.
• New host records are documented for Catadelphops nasutus (Sphingidae) and Aethianoplis excavata (Nymphalidae).

Conclusions:

• The taxonomic revisions clarify the systematic status of numerous Ichneumonid species.
• The study contributes to a more stable and accurate classification of the Ichneumonidae family.
• New host records expand the understanding of Ichneumoninae ecological interactions.
