Another species of Quadrastichus (Hymenopera; Eulophidae; Tetrastichinae) attacking Erythrina (Fabaceae) in the Neotropics: a report from Costa Rica

Description of two new Quadrastichus (Hymenoptera: Eulophidae) reared from Litchiomyia chinensis (Diptera: Cecidomyiidae) on commercial lychee (Litchi chinensis; Sapindaceae) in Taiwan

“…The primary example is Q. erythrinae Kim which induces galls on coral bean trees (Erythrina spp. : Fabaceae) ( Kim et al 2004) and has spread from its hypothesised native range in Africa (Messing et al 2009) into many tropical regions (detailed by Jansen-Gonázlez et al 2019). Most recently, Jansen-Gonázlez et al (2019) reported on a second Erythrina-galling species detected in Costa Rica that keys to Q. bardus in the key of Prinsloo and Kelly (2009) but differs biologically in galling stems rather than leaves.…”
