A NEW ANAGRUS (HYMENOPTERA: MYMARIDAE) FROM ARGENTINA, AN EGG PARASITOID OF DELPHACODES SITAREA (HEMIPTERA: ARCHAEORRHYNCHA: DELPHACIDAE)

Abstract

In a review of the Argentine species of the fairyfly genus Anagrus Haliday (Hymenoptera: Mymaridae), Triapitsyn (2000) keyed, diagnosed, and illustrated an unnamed species (called A. sp. E) from Buenos Aires, Misiones, Neuquen, and Santiago del Estero Provinces of Argentina. It was not described as new then because all the specimens were improperly slide-mounted and had no host association data. Recently, the junior author reared a large series of individuals of Anagrus near San Miguel de Tucuman from eggs of the planthopper Delphacodes sitarea Remes Lenicov and Teson (Hemiptera: Archaeorrhyncha: Delphacidae) laid in pasture or lawn grass, Stenotaphrum secundatum (Walter) Kuntze (Poaceae). These specimens were sent for identification to the senior author, who found them to be conspecific with A. sp. E of Triapitsyn (2000). Availability of fresh, reared specimens of this species has enabled us to describe it herein as A. ( Anagrus ) miriamae sp. nov. Terms for morphological features are those of Gibson (1997). Measurements are given in micrometers (μm) as length or, where appropriate, as length/width. Abbreviations (codens) for depositories of specimens are as follows: CNCI, Canadian National Collection of Insects, Ottawa, Ontario, Canada; IEFA, E. Chiappini collection, Istituto di Entomologia e Patologia Vegetale, Universita Cattolica del Sacro Cuore, Piacenza, Italy; IMLA, Fundacion e Instituto Miguel Lillo, San Miguel de Tucuman, Tucuman, Argentina; MLPA, Museo de La Plata, La Plata, Argentina; UCRC, Entomology Research Museum, University of California, Riverside, California, USA. An abbreviation used in the text is: F = funicle (in females) or flagellar (in males) antennal segment.
