A monograph of Siphini Mordvilko, 1928 (Hemiptera, Aphidoidea: Chaitophorinae)

Abstract

The monograph presents the tribe Siphini Mordvilko, 1928 on a worldwide scale. 5 genera, 24 species and 1 subspecies are discussed in detail. 69 morphs (apterous viviparous female, alate viviparous female, oviparous female, male) are redescribed or described and figured in detail. The keys to all known species and morphs are provided. A new synonym is proposed: Sipha (Rungsia) aegilopis Bozhko, 1961 = Sipha (Rungsia) elegans Del Guercio, 1905. The lectotype for Sipha (R.) elegans is designated. New country records for most species are presented as well as new bionomical data for 6 species (Atheroides serrulatus Haliday, 1839; Chaetosiphella stipae Hille Ris Lambers, 1947; Laingia psammae Theobald, 1922; Sipha (Rungsia) arenarii Mordvilko, 1921; S. (R.) elegans and S. (R.) maydis Passerini, 1860). During the field study the sexuales of Ch. stipae were collected and have been described for the first time. There is also provided a host index compiled from the material studied and the literature cited. The structure of reproductive system of adult males of A. serrulatus, Ch. stipae, L. psammae, S. (R.) arenarii, S. (R.) elegans and S. (R.) maydis has been studied in the light and transmission electron microscopy, as well as the morphological characters of A. serrulatus, Caricosipha paniculatae Börner, 1939, Ch. stipae and S. (R.) maydis that have been studied using SEM techniques. All available data concerning chorology, ecology and bionomy of the species belonging to this tribe is summarized in the study, as well as the relationships within the Siphini and the genesis of this group of aphids is proposed.
