Kinsey: Gall Wasp Genus Cynips
483
Hypopygial spine very large, as high as long, extending dorsally as far as or further than ventrally (see figs. 217-224); wing-body ratio 1.50; cubital and discoidal cells always spotted; Pacific Coast species not known east of the Sierras.Subgenus Besbicus, 9 | |
Hypopygial spine usually more drawn-out and slender (broad in Philonix especially in short-winged forms), the normal wings 1.17 to 1.35 times the body length, but many forms with wings much reduced. Always east of the Sierras, from Mexico to southeastern Canada.3 | |
3. | Wing-body ratio normally 1.17, the wings without spots except for traces of a blotch in the cubitus; second abscissa of radius rather straight, radial cell rather long, wide; the normal spine rather broad but projecting basally; many forms with wings much reduced and the spine much broadened and abruptly truncate posteriorly. Agamic galls of moderate size or small, spherical; bisexual forms in seed-like cells in buds.Subgenus Philonix, 12 |
Wing-body ratio normally 1.35; wings with spots and patches in many of the cells; second abscissa of radius well curved, radial cell usually short and broad (see figs. 266-273); the spine rather long and slender, not greatly widened (see figs. 276-286); the wings sometimes reduced. Agamic galls large, strictly spherical, smooth and naked “oak apples”; bisexual forms unknown.Subgenus Atrusca, 13. | |
Wing-body ratio normally 1.30, wings largely clear or with smoky patches in the cubital cell; radial cell moderately long and not narrow (see figs. 345-368), normal spine rather slender plough-shaped (see figs. 386-406); or wings reduced, sometimes to mere stubs, and then the spine usually slender, blunt, of uniform width (see figs. 407-429); agamic galls more or less spherical, ellipsoid, or conical, naked, spiny, or woolly, usually thick-walled and compact crystalline internally in all species except mellea; bisexual forms in seed-like cells in buds.Subgenus Acraspis, 16 |
SUBGENUS CYNIPS
4. | Agamic female with abdomen not more than half again as long as high, with tip of second segment approaching tip of abdomen dorsally; the central European varieties with the mesonotum largely punctate and hairy. Bisexual adults with mesonotum and mesopleura entirely smooth. Agamic galls spherical with considerable spongy tissue inside; bisexual galls seed-like, on twigs or older branches or the main trunk.5 | |
Agamic female with abdomen fully twice as long as high, with tip of second segment extending two-thirds or less to tip of abdomen; the Central European varieties with the mesonotum largely smooth |
