description: <i>Kamimuria gressitti</i>, sp. nov. (Figs. 1-8) <b>Material examined.</b> Holotype &amp;male; and paratype &amp;female; from <b>CHINA</b>, W. Hupeh (Hubei Province), Lichuan District, Suisapa, 1000 m, 23 August 1948, J.L. Gressitt, Djou (California Academy of Sciences). <b>Adult Habitus.</b> Three ocelli. Color pattern apparently pale brown, without distinctive pattern, but obscured by specimen condition. Wings pale, veins pale amber. <b>Male.</b> Forewing length 20.5 mm. Hemitergal lobes slender, finger-like, bluntly rounded at the apex and bearing a small patch of sensilla basiconica along ventroapical margins (Figs. 1-2); hemitergal lobes meet in median field of tergum 10 in dorsal aspect, and approach anterior margin of tergum 10; in lateral aspect a slight ventral swelling occurs near midlength of hemitergal lobes (Fig. 2). Tergum 9 with a median patch of sensilla basiconica; sterna 4-6 with well developed hair brushes. Aedeagus membranous, relatively straight, but constricted subapically, near midlength, and at base of aedeagal tube (Fig. 4); armature extensive on subapical sac portion, consisting of a circular band of sharp, triangular spines; band narrowly divided medially on dorsal surface and more broadly on ventral surface; fine microtrichia occur in a pair of apicolateral patches (Figs. 3-4) and similar patches occur ventrally on the middle tube section (Fig. 5) and ventrally on the basal envelope section (Fig. 5). <b>Female.</b> Forewing length 22 mm. Subgenital plate a short, triangular projection, barely reaching the anterior margin of sternum 9 (Fig. 6), and bearing a small median notch. Vagina membranous but partially lined with pale setae around wide posterior section at gonopore; anterior section slightly narrower from midlength, and bearing a prominent, balloon-like spermatheca on a slender stalk (Fig. 7). <b>Egg.</b> Length ca. 0.41 mm, width ca. 0.24 mm. Somewhat barrel shaped with short, wide, slightly flanged collar (Fig. 8). Chorion smooth. <b>Larva.</b> Unknown. <b>Etymology.</b> The patronym honors the late J. Linsley Gressitt, distinguished Coleopterist and Naturalist, director of the “Dawn Redwood Expedition”, and co-collector of the type series of this species. <b>Diagnosis.</b> The aedeagal armature size and general aedeagal shape is somewhat similar to that of <i>K. similis</i> Klapálek (Sivec &amp; Stark 2008), however the new species lacks the enlarged pair of dorsal spines found in <i>K. similis</i>, and the hemitergal lobes of the latter species bear an abrupt subapical notch not found in the new species. There is also a general similarity with <i>K. atrocephala</i> Sivec &amp; Stark, however that species has a more extensive patch of lateral spines along the aedeagal tube and sac, and a small patch of sensilla basiconica on tergum 8. Unfortunately, the provisional key in Sivec &amp; Stark (2008) is based, in part, on pigment patterns and is therefore, unsuitable for specimens like these which have obscure pigmentation.
