Camptotylus Fieber

Camptotylus Fieber, 1860: 70 . Type species by subsequent monotypy ( Fieber, 1861): Capsus yersini Mulsant and Rey, 1856 .

Exaeretus Fieber, 1864: 81 (syn. by Reuter, 1891: 7). Type species by monotypy: Camptotylus meyeri Frey- Gessner, 1863.

Megalobasis Reuter, 1879: 205 (syn. by Reuter, 1891: 7). Type species by monotypy: Megalobasis bipunctatus Reuter, 1879 .

DIAGNOSIS: The genus is unequivocally recognized by the following combination of characters: dorsum greenish to pale yellow, sometimes with scattered green, always with conspicuous small, dark, roundish spot in medioapical area of corium; claws slender and smoothly curved, pulvilli absent (figs. 35, 36, 49); vesica composed of two straps: one gutterlike smoothly curved, with secondary gonopore at apex that is tightly fastened to the second, which is twisted, bent, and strongly dentate apically, and which extends far beyond secondary gonopore ( Figs 4, 6 ); secondary gonopore located at middle of vesica; apex of theca with prominent spinelike to nearly rectangular sclerotized process (figs. 15–21); left paramere atypical, usually with welldeveloped central process in addition to apical process and sensory lobe (figs. 23–26), rarely boat-shaped (fig. 34); labium relatively short, barely reaching middle coxae, usually with somewhat swollen articulation of segments III and IV.

Some of the distinctive features mentioned above are occasionally found in other Phylini genera. Absence of pulvilli is typical of Tuponia spp. , while the sclerotized process of the theca and the central process of the left paramere are known in Yotvata spp. Camptotylus spp. are most similar in the color pattern to the Camptotylidea bipunctata group of species although all three species of that group differ from Camptotylus in the presence of brown dotting on forewings.

HOST PLANTS: All species of Camptotylus are specialized feeders on Tamaricaceae . Almost all are known to breed on Tamarix spp. , one species described here is found on Reaumuria soongorica and C. meyeri is report- ed from both Tamarix laxa and Reaumuria oxiana .
