A New Species

A new species of the termite genus <em>Gyatermes</em> Engel &amp; Gross (Archotermopsidae) is described and figured from a beautifully preserved forewing in late Neogene sediments of Nagano Prefecture, central Japan.  The approximately 27-mm long forewing of <em><strong>Gyatermes naganoensis</strong></em> Engel &amp; Tanaka, new species, is preserved in Late Miocene (late Messinian) mudstone of the Ogawa Formation (<em>ca</em>. 6 Ma), and is distinguished from its slightly older and larger congener <em>G. styriensis</em> Engel &amp; Gross, from the early Tortonian of Styria, Austria.  Comments are provided regarding the paleoclimatic implications of a giant termite in the Miocene fauna of Nagano.
