<p>The genus <em>Chetostoma</em> Rondani 1856 belongs in the subtribe Chetostomatina (Trypetini) along with <em>Anomoia</em>, <em>Myoleja</em>, and several other genera mainly developing in the fleshy fruits of <em>Lonicera, Cotoneaster, </em><em>Ilex </em>and some other plants. The genus includes about a dozen of species occurring in the Palaearctic, Nearctic and Oriental Regions. Larvae of at least one species, <em>C. continuans</em> (Chen 1938) from the Palaearctic Far East live in the fruits of <em>Lonicera</em>, whereas the others are believed to be inquillines in the galls of sawflies. In Europe, along with the most peculiar type species of the genus, <em>C. curvinerve</em> Rondani 1856, which occurs predominantly in the Mediterranean contries from Portugal to Israel and further to Kyrghyzstan and Uzbekistan, a less known species, <em>V. stackelbergi</em> (Rohdendorf) occurs mainly in the North and Middle Europe (Merz & Korneyev 2004: FaunaEuropaea).</p>
<p>Through the kindness of Dieter Doczkal (ZSS Munich), ♂ & ♀ of <em>C. stackelbergi </em>collected in Bavaria (Inning, Schlagenhodfen, at light, 3.viii.2006, K.Ambil leg.) have become available for study. I appreciate assistance of Bernhard Schurian (Leibnitz Museum fur Naturkunde, Berlin) for the photo facilieties used to prepare the pictures of this rare species. </p
