On the parasitoid complex of butterflies with descriptions of two new species of parasitic wasps (Hymenoptera: Eulophidae) from Goa, India

摘要

In comprehensive rearing of butterflies from Goa, India, an interesting parasitoid complex of wasps and tachinid flies was found. Two new species of parasitic wasps are described and illustrated: Tetrastichus thetisae n. sp. (Hymenoptera: Eulophidae), a gregarious parasitoid reared from the pupa of Curetis thetis (Drury) (Lepidoptera: Lycaenidae) on the host plant Derris sp., and Sympiesis thyrsisae n. sp. (Hymenoptera: Eulophidae), a gregarious parasitoid reared from the caterpillar of Gangara thyrsis (Fabricius) (Lepidoptera: Hesperiidae) on the host plant Cocos nucifera L. Additionally, the following host-parasitoid associations are recorded: Amblypodia anita Hewitson (Lepidoptera: Lycaenidae) with Parapanteles sp. (Hymenoptera: Braconidae); Coladenia indrani (Moore) (Lepidoptera: Hesperiidae) with Sympiesis sp. (Hymenoptera: Eulophidae); Danaus chrysippus L. (Lepidoptera: Nymphalidae) with Sturmia convergens (Wiedemann) (Diptera: Tachinidae); Idea malabarica Moore (Lepidoptera: Nymphalidae) with Brachymeria sp. (Hymenoptera: Chalcididae) and Palexorista sp. (Diptera: Tachinidae); Notocrypta curvifascia Felder & Felder (Lepidoptera: Hesperiidae) with Cotesia erionotae (Wilkinson) (Hymenoptera: Braconidae); and Rapala sp. (Lepidoptera: Lycaenidae) with an inominate species close to Aplomya spp. (Diptera: Tachinidae). This discovery is the first record of Tetrastichus as parasitoid of Curetis thetis, Sympiesis as parasitoid of Gangara thyrsis and Coladenia indrani, Brachymeria and Palexorista as parasitoids of Idea malabarica, and Cotesia erionotae as parasitoid of Notocrypta curvifascia. Data on habitat, brief diagnoses and host records for all parasitoids are provided.
