Genus Dryodurgades Zachvatkin

Durgades (Dryodurgades) Zachvatkin, 1946: 146 . Type-species: Agallia reticulata Herrich-Schäffer , by original designation. Dryodurgades Zachvatkin : Wagner, 1963: 1.

Morphology. Head short, wider than pronotum. Hind margin of vertex sinuately curved laterally behind eyes. Ocelli closer to adjacent eyes than to each other. Transclypeal sulcus complete, lora often tumid. Head and thorax granulate. Forewings with numerous accessory cross veins. Forefemora with intercalary setae arranged in arched row, two setae of row AV stout, one of them long and prominent ( Fig. 25). Hind tibial macrosetae PD 10±2, AD 7±1, AV 6±1. Hind basitarsus with one platella on distal transverse row of setae.

Male genitalia. Subgenital plates without macrosetae, triangular, apically pointed. Pygofer without processes, caudal lobe rounded. Connective broader than long. Aedeagus symmetrical, dorsal apodeme and socle well developed, shaft usually compressed and with apical and often subapical branched processes. Gonopore apical or slightly subapical. Anal collar often well developed.

Female genitalia. First pair of valvulae with sculptured area occupying more than half length, sculpture elongate, cell-like, closely packed in oblique rows, submarginal, cells more or less of uniform size ( Figs 52, 53). Second pair of valvulae of uniform width except apically, teeth crenulate, very minute, ventroapical margin crenulate ( Figs 54–55).

Distribution. Palaearctic and Oriental.

Remarks. Dryodurgades closely resembles Igerna Kirkaldy in the shape of the vertex and style. It differs from Igerna in the following features: 1. numerous cross veins on forewings; 2. face more coarsely granulate and flat; 3. pronotum flat; 4. aedeagus with well developed but laterally compressed dorsal apodeme and 4. connective broader than long. The genus is largely Palaearctic but two species occur in the Oriental region in addition to an undescribed species represented only by females from Myanmar (BMNH). The Palaearctic Drydurgades reticulata (Herrich-Schaffer) is also illustrated ( Figs 565, 579, 594) here to facilitate recognition of the genus.
