description: <i>Gryponeura quadrimaculata</i> (Cameron) (Figs. 17–21) <i>Xiphydria quadrimaculata</i> Cameron 1899: 4, Maa 1949: 76 (unplaced species). <i>Gryponeura quadrimaculata</i>: Benson 1954: 162, Smith 1978: 109 (in catalog). Diagnosis.—Female (Fig. 17). Length, 14.0 mm. Black with base of mandible, lateral posterior margin of pronotum, basal ¼ to 1/3 of hind tibia, mid and hind basitarsi, and lateral spot on abdominal tergite 4 white. Antenna with 11 antennomeres short, slightly incrassinated at middle, about 0.8 X head width. Head (Figs. 20, 21) entirely sculptured. Labial palpus with 3 palpomeres; 1 st and 3 rd long, subequal; 2 nd short. Maxillary palpus with 4 palpomeres; 2 nd and 4 th long, subequal in length; 1 st shorter than 2 nd; 3 rd very short. Hind tarsal claw with small inner tooth, slightly less than half length of outer tooth; fore and mid claws more slender, inner tooth slightly more than half length of outer tooth. Sheath (Fig. 17) short, about 0.8X length of basal plate. Male. Length 8.0 mm. Similar to female. Specimens examined.— Lao, Hua Phan Prov., Ban Saleui, Phou Pan Mt., 20 <i>°</i> 13'30"N, 103 <i>°</i> 59'26"E, 1350 - 1900 m, 06.05.2011, leg. C. Holzschuh + locals (2 &amp;female;, OML, USNM), same except 13.05.2011 (1 &amp;female;, OML), 10.05.2011 (1 &amp;female;, OML), 04.05.2011 (3 &amp;female;, 2 OML, 1 USNM). Lao, Prov. Hua Phan, Phou Pan, Umg. Ort Ban Saleui, 20 <i>°</i> 13'30"N, 103 <i>°</i> 59'26"E, 1350 - 1900 m, 21.05.2011, leg C. Holzshuh + locals (1 &amp;female;, OML), same except 27.04.2012 (1 &amp;female;, OML). China, 1000 0 1300 m, Shaanxi, Qinling Mts., Xunyangba (6 km E), 23.V- 13.VI.1998, I. H. Marshal leg. (1 &amp;female;, OML). Remarks.—Two species of <i>Gryponeura</i> are known, <i>G. quadrimaculata</i> described from Khasia Hills, India, and <i>G. orientalis</i> (Westwood 1874) described from Sri Lanka. Both are very similar. According to Benson (1954) they can be separated by the length of the pubescence on the head and thorax. <i>Gryponeura orientalis</i> has longer pubescence on the temples and mesonotum, some of it longer than the diameter of the hind ocellus. <i>Gryponeura quadrimaculata</i> has this pubescence only half to three-quarters this length. In the specimens examined, the pubescence compares to the latter. These are the first records of <i>G. quadrimaculata</i> from Laos and China.
