Abstract

Four new species of brachypterous Encyrtidae (Hymenoptera: Chalcidoidea) are described. These are: Cheiloneurus mandyanus Hayat, sp. nov., Encyrtus coorgensis Hayat & Zeya, sp. nov., Microterys atturensis Hayat, sp. nov. and Pseudectroma indicum Hayat & Zeya, sp. nov. The following species that exist either in brachypterous forms only or in both brachypterous and macropterous forms are recorded: Anomalicornia tenuicornis Mercet, Cheiloneurus bangalorensis (Subba Rao), C. quadricolor (Girault), Diversinervus cervantesi (Girault), Globulencyrtus politus (Hoffer), Indaphycus planus Hayat, Neodusmetia sangwani (Subba Rao), Prochiloneurus bolivari Mercet, Rhopus atys Noyes & Hayat and Sakencyrtus mirus Hayat. Globulencyrtus politus and P bolivari are newly recorded from India. A diagnosis of Globulencyrtus, and redescriptions of G politus, P bolivari based on the Indian specimens and of the brachypterous forms of R. atys are given. The occurrence of brachyptery in the Encyrtidae is briefly noted together with a list of brachypterous species recorded from India.
