description: <i>Hyperxiphia flava</i> Smith, new species http://zoobank.org/BF25446F-270F- 4D34-8559-C833135A8383 (Figs. 6–10) Diagnosis.—Entirely orange, shiny; wings hyaline with apex infuscated. Mesepisternum with large punctures separated by distance mostly greater than puncture diameters. Sheath long, slender, about 4X longer than broad and slightly turned up toward apex. Description.—Female (Fig. 6): Length 16.0 mm. Antenna black, scape dark orange. Head, thorax, abdomen, and legs orange. Wings hyaline to yellow, slightly darkened at apex; veins and stigma black. <i>Head</i> (Figs. 9, 10): Antenna with about 19 antennomeres. Frons with longitudinal carinae from line of hind ocelli through frons and supraclypeal area and inner orbits. Eyes slightly diverging below (Fig. 9); lower interocular distance 1.2X eye height. Labium with 4 palpomeres, 1 st palpomere long, about as long as rest of palpomeres; apical palpomere clublike; 3 rd palpomere small and difficult to see; maxilla with 5 palpomeres. In dorsal view, head behind eyes about equal to eye length. <i>Thorax</i> (Figs. 7, 8): Propleuron shiny, few punctures mostly on venter; pronotum mostly smooth, shiny, with narrow diagonal line of short carinae and upper edge rugulose; mesonotum and metanotum rugulose with some indistinct transverse carinae at posterior of mesoscutum; notauli broad and distinctly scrobiculate; mesopleuron shiny with scattered punctures mostly farther apart than puncture diameters; mesosternum shiny without punctures; mesepimeron with some cross carinae; metapleuron rugulose. Hind claw with small inner tooth, less than half length of outer tooth and at center of claw; fore and mid claws more slender, inner tooth longer than half length of outer tooth and closer to outer tooth. Hind basitarsus subequal in length to remaining tarsomeres combined. <i>Abdomen</i>: Sheath (Fig. 6) slender in lateral view and slightly turned up toward apex; about 4.0 X longer than broad; 0.9X length of basal plates. Male (specimen marked with asterisk below): Length 11.0 mm. Inner orbits, malar space, lower gena, base of mandible, propleuron, mesosternum, and coxae more yellow than orange. Type material.— Holotype female “ Lao, Hua Pham Prov., Ban Saleui, Phou Pan Mt., 20 <i>°</i> 13'30"N / 103 <i>°</i> 59'26"E, 1350- 1900 m, 07.05.2011, leg. C. Holzschuh &amp; locals (OLM). Paratypes: Same data as holotype except 3- 04.05.2010 (1 &amp;female;, OLM), 13.05.2010 * (1 Ơ, OLM), 02.05.2011 (1 &amp;female;, USNM), 06.05.2011 (1 Ơ, USNM), 17.05.2011 (1 Ơ, OLM), 18.05.2011 (1 Ơ, OLM), 22.05.2011 (1, apex abdomen missing, OLM), 29.04.2012 (1 Ơ, OLM), 30.05.2011 (1 Ơ, OLM); 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, 23.04.2012, leg. C. Holzschuh &amp; locals (1 &amp;female;, OLM), same except 01.06.2011 (1 &amp;female;, OLM), 11-12,04.2012 (1 Ơ, OLM), 12.04.2012 (1 f, OLM), 19.04.2012 (1 &amp;female;, USNM). Etymology.—The name is based on the entirely orange color. Remarks.—No other xiphydriid is entirely orange as this species. The dorsal margin of the sheath is slightly concave, making it appear that the sheath is slightly turned up at its apex. The third palpomere is short and difficult to see, sometimes making the labium appear to have three palpomeres. The maxillary palpus appears to have four palpomeres, but maybe five as the apical may be divided into two. The size range is 12–17 mm for females, 10–15 mm for males. The color is uniform in the specimens examined.
