New species of Idris Förster (Hymenoptera, Platygastroidea) from southeast Asia, parasitoids of the eggs of pholcid spiders (Araneae, Pholcidae)

Abstract

Four new species of the genus Idris Förster (Hymenoptera: Platygastroidea), reared from the eggs of pholcid spiders (Araneae: Pholcidae) in southeast Asia are described on the basis of external morphology and the barcode region of the mitochondrial COI gene. The new species and their hosts are: I. badius Johnson & Chen, sp. n. (ex Nipisa phyllicola (Deeleman-Reinhold), Panjange hamiguitan Huber), I. balteus Johnson & Chen, sp. n. (ex Panjange camiguin Huber), I. curtus Johnson & Chen, sp. n. (ex Calapnita nunezae Huber, Panjange camiguin Huber, Tissahamia bukittimah (Huber), Uthina luzonica Simon), and I. fusciceps (ex Belisana khaosok Huber).
