Megaplectes Forster 1869

Genus Megaplectes Förster, 1869 Megaplectes Förster, 1869: 186. Type species: Ichneumon monticola Gravenhorst, 1829. Included by Schmiedeknecht (1890). Iocryptus Thomson, 1873: 472. Phygadeuon regius Taschenberg, 1865 (= Ichneumon monticola Gravenhorst, 1829). Monotypic. Megaloplectes Schulz, 1906: 124. Emendation. A single species including two subspecies, Meg. monticola monticola (Gravenhorst, 1829) and Meg. monticola dentatus Uchida, 1930, have been recorded from Japan. Uchida (1936b) recorded Meg. monticola (Gravenhorst, 1829) and noted that the specimens from Shikoku have no horn of head. Townes & Gupta (1962) reviewed the subspecies of this species and noted that the subspecies, Meg. monticola dentata Uchida, 1930, has an intraspecific variation, i.e. horn of frons sometimes absent. According to Townes & Gupta (1962), all Japanese specimens of Meg. monticola should be treated as Meg. monticola dentatus. Thus, I delete the distribution of Meg. monticola monticola from Japanese fauna. In this study, I newly describe two new species and redescribe Meg. monticola dentatus below.
