Biosystematic Stydies of Ceylonese Wasps, XI: A Monography of the Amiseginae and Loboscelidiinae (Hymenoptera: Chrysididae)

Abstract

SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 376 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoo/ogy Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover.

First record of Isegama Krombein (Hymenoptera, Chrysididae, Amiseginae) from China, with description of a new species

“…Both sexes are fully winged, and the antennae are remarkably similar in morphology, being short and stout, tapering apicad, flagellomeres flattened on ventral surface (Krombein 1983). However Isegama can be separated from Perissosega by the following characteristics: mesopleuron with omaulus and scrobal sulcus (without omaulus and scrobal sulcus in Perissosega); forewing Rs extended by evenly curved dark streak (Rs extended at right angles by dark streak in Perissosega); metapectal-propodeal complex (sensu Kawada et al 2015) rounded laterally and posteriorly (propodeal tooth long and acute in Perissosega) (Krombein 1983;Kimsey & Bohart 1991). The host of Isegama is still unknown (Kimsey & Bohart 1991).…”

“…Similar to Perissosega Krombein, 1983, the species of Isegama also exhibit very little sexual dimorphism. Both sexes are fully winged, and the antennae are remarkably similar in morphology, being short and stout, tapering apicad, flagellomeres flattened on ventral surface (Krombein 1983).…”

“…Until now, three species of this genus, I. meaculpa, I. aridula and I. malaysiana Kimsey, 1986 were reported only from Oriental Region, Sri Lanka and Malaysia (Krombein 1983;Kimsey 1986), whereas no data was known from China (Kimsey & Bohart 1991). In the course of our survey on the Chinese Chrysididae fauna, one new species of Isegama is discovered and described herein.…”

“…The genus Isegama was erected in the subfamily Amiseginae by Krombein (1983) to accommodate the two new species, I. meaculpa Krombein, 1983 and I. aridula (Krombein, 1980) from Sri Lanka, with I. meaculpa as type species.…”

Indothrix Krombein, 1957 (Hymenoptera, Chrysididae) newly recorded genus from China, with description of one new species

“…At present, two species, Indothrix longicornis Krombein, 1957, I. wijesinhei Krombein, 1983, are recorded from Oriental Region, southern India and Sri Lanka respectively (Krombein 1957(Krombein , 1983, whereas no data are known from China. In the course of our survey on the Chinese Chrysididae fauna, one new species of the genus Indothrix is discovered and described herein.…”
