Epomial carina present, diminishing medially; cervical and lateral pronotal areas smooth; netrion sulcus complete, netrion as wide as fore coxa; pronotal suprahumeral and cervical sulci complete, foveolate; mesoscutum less than 1.5 times as wide as long (TSL/ML =1.37); notaulus normal, almost reaching transscutal line; reticulate sculpture of mesoscutum not extending to inter and lateral notaular areas; mesoscutellum 2 times as wide as long (SW/SL =2.04); scuto-scutellar sulcus distinctly diminishing medially, 4–5 times as wide laterally as in the middle; mesoscutellum smooth, with sparse, long marginal setae; posterior scutellar sulcus not extending onto axillula; sternaulus not separated from anterior row of foveae of mesopleural carina; mesopleural carina incomplete; foveae of mesepimeral sulcus transversely elongated; sulcus along metapleural carina foveolate; metascutellum bluntly triangular, metanotal spine reduced; propodeal lateral carinae inverted V-shaped, shafts distinctly curved outward; propodeal lateral and plical areas obscured by dense setae, marginal striation extending medially; posterior propodeal projection indistinct; fore wing distinctly wider than mesoscutum (TSL/WW =0.72); marginal vein more than 3.5 times as long as stigmal vein (m/st =3.84); hind wing about 1.5 times as wide as marginal cilia length (HWW/ HWS =1.66).

T1, slightly wider than T1+T2 length (T1W/T1+T2L =1.18); T3 less than 1.5 times as wide as long (T3W/T3L=1.30), about as wide as mesoscutum (T3W/TSL =0.90); costae on T3 not extending to 1/5 of tergum; lateral patch distinct, elongate, 4–5 times as long as wide; posterior patch of T3 nearly equal to width of one basal depression; lateral patch on T4 present, median patch marked by punctures.

FEMALE: Unknown.

Diagnosis. Most closely related to X. gloriosus , differing by the incomplete mesopleural carina.

Etymology. The name refers to the collector of the species, T. Hiller.
