ENCYRTIDAE OF COSTA RICA (HYMENOPTERA: CHALCIDOIDEA), 4 Subfamily Encyrtinae: tribes Arrhenophagini, Habrolepidini, Cerapterocerini, Cheiloneurini, Trechnitini, Cercobelini, Polaszekiini, Protyndarichoidini, Gahaniellini and Syrphophagini (part), mainly primary parasitoids and hyperparasitoids of Coccoidea and Psylloidea (Hemiptera)

Abstract

A taxonomic study of fifty one genera known to occur in Costa Rica, belonging to ten tribes of the subfamily Encyrtinae (Encyrtidae). The genera are characterised by means of generic diagnoses and the biology and distribution of included species is summarized. Identification keys to the genera and 316 Costa Rican species are provided. All species are illustrated and defined by means of brief diagnoses or full morphological descriptions, and information is provided on their known distributions, host ranges, and use in biocontrol.

Fifty one genera known to occur in Costa Rica, belonging to ten tribes of the subfamily Encyrtinae (Encyrtidae), are characterised by means of generic diagnoses. Their biology and use in biocontrol are summarized for every genus and identification keys to the 316 Costa Rican species are provided. All species are illustrated and defined by means of brief diagnoses or full morphological descriptions, and information is provided on their known distributions, host ranges, and use in biocontrol. Three family group names are proposed as new (Gahaniellini, Protyndarichoidini, Polaszekiini); 21genera are described as new (Alkonia, Angebra, Arianus, Dalek, Elaxis, Esphora, Georynus, Harlarus, Hebynthus, Ludesia, Mendisa, Oodia, Orixia, Polaszekius, Prionias, Quetsira, Raquanus, Sosara, Stadima, Strigenia, Tico); 254 species are described as new
