Symphyta new species key lectotypes

Abstract

The Japanese species of the sawfly genus Siobla Cameron, 1877, are revised and keyed. The following nine species are recognized: S. apicalis Takeuchi, 1929, S. ferox (Smith, 1874), S. hirasana Takeuchi, 1929, S. jucunda (Mocsáry, 1909), S. metallica Takeuchi, 1929, S. sturmii (Klug, 1817), S. japonica, sp. nov., S. pulchra, sp. nov., and S. takeuchii, sp. nov.  Siobla pacifica (Smith, 1874) is synonymized with S. sturmii. Lectotypes are designated for Macrophya ferox Smith, 1874, Macrophya pacifica Smith, 1874, Encarsioneura jucunda Mocsáry, 1909, and Siobla grandis Matsumura, 1912. Previous records of S. ruficornis (Gimmerthal, 1834) and S. villosa Malaise, 1931, from Japan have been found erroneous. Siobla jucunda is newly recorded from Japan.
