Type material. Holotype: apterous male, CHINA, Yunnan Prov., Xishuangbanna, Jinghong city, Puwen town, Caiyanghe River (22°30' N, 101°04' E), alt. 885 m, 25.IX.2011, coll. Zhen Ye. Paratypes: CHINA, Yunnan Prov., 2 apterous males, 2 macropterous males and 3 macropterous females, same data as for holotype.

Diagnosis. X. fulva sp. nov. can be distinguished with its closely related X. glauca by relatively shorter body length (1.53–1.55) ( Fig. 8 View FIGURES 5 – 10 ); head dorsum yellowish brown ( Fig. 8 View FIGURES 5 – 10 ); position of silvery hair markings on abdominal tergites (laterally on mediotergum II, medially on mediotergites III – VII, and inner region on laterotergites III and VI); the ear-like process on each side of pygophore much wider in caudal view ( Fig. 28 View FIGURES 21 – 29 ).

Description. Apterous male ( Fig. 8 View FIGURES 5 – 10 ). Colour: ground colour brown; head dorsum yellowish brown, ventrally grayish, clypeus shining yellow, labrum shining black, rostrum yellowish brown with black apex; antennal segments I–II dark yellow, III–IV brown; pronotum with a transverse band brown, meso- and metanotum black, mesonotum with a pair of rounded, silvery hair markings; legs yellowish with apices of femora, tibiae and tarsi weakly infuscated ( Fig. 8 View FIGURES 5 – 10 ), apical half of fore femora ventrally with black patches ( Fig. 13 View FIGURES 11 – 20 ); abdomen dorsally black, mediotergites III–VII medially, mediotergite II laterally and inner region of laterotergites III and VI with silvery hair markings; abdominal segment VIII, pygophore yellowish (after dissection), each weakly infuscated apically ( Figs. 24, 28 View FIGURES 21 – 29 ).

Genital segments: abdominal segment VIII ( Fig. 24 View FIGURES 21 – 29 ) about 1.35 times as long as wide, posterior margin with some short, sparse, erect, black brown hairs; pygophore ( Fig. 28 View FIGURES 21 – 29 ) swollen at posterior end in ventral aspect and with a very broad ear-like process on each side; paramere rudimental.

Macropterous male ( Fig. 9 View FIGURES 5 – 10 ).

Etymology. The specific name is derived from the Latin fulvus means yellowish brown, refers to head dorsum of apterous male almost yellowish brown.
