Xenomerus varipes Dodd, 1914: 83 . Original description. Kieffer, 1926: 174, 175 (description, keyed); Dodd, 1930: 89 (description, keyed).

FEMALE (n=10): Length= 0.89–1.62 mm (m=1.29, SD =0.27).

Black; metasoma dark brown to light brown, sometimes with darker apex, apex of interantennal process, radicle, A1–A6, mandibles, legs, excluding apical light brown tarsomeres yellow.

FCI =1.17–1.21 (m=1.19, SD =0.01); LCI =1.68–1.76 (m=1.71, SD =0.03); HW/IOS =1.54–1.60 (m=1.57 SD =0.01); head less than 1.5 times as wide as mesosoma (HW/TSL =1.41–1.48, m=1.43, SD =0.02); facial striae extending to midlevel of eye, parallel on frons, obscuring frontal patch; frontal patch indistinct; frons setae sparse, thin; central keel complete; toruli triangle shorter than clypeus height; POL as long as OOL (POL/OOL =0.96–1.08, m=1.01, SD =0.03); OOL about 2 times as long as LOL (OOL/LOL =1.84–2.1, m=1.97, SD =0.09); hyperoccipital carina absent; vertex smooth; genal patch absent; A1 more than 5.0 times as long as radicle (A1/r =5.5–6.5, m=6.04, SD =0.34), about as long as clava (A1/cl =0.97–1.1, m=1.04, SD =0.04).

Epomial carina present, reaching pronotal suprahumeral sulcus; cervical and lateral pronotal areas smooth; netrion sulcus incomplete, diminishing ventrally; pronotal suprahumeral and cervical sulci complete, foveolate; mesoscutum about 1.5 times as wide as long (TSL/ML =1.45–1.52, m=1.48, SD =0.02); notaulus normal, almost reaching transscutal line; granulose sculpture of mesoscutum extending to lateral and internotaular areas, not reaching posterior margin of mesoscutum; mesoscutellum about 2.0 times as wide as long (SW/SL =1.96–2.16, m=2.03, SD =0.07); scuto-scutellar sulcus 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; distance between postacetabular sulcus and anterior row of foveae of mesopleural carina equal to foveae width of postacetabular sulcus; mesopleural carina complete, with complete rows of foveae; foveae of mesepimeral sulcus transversely elongated, 4–5 times as long as wide; sulcus along metapleural carina foveolate; metascutellum pointed, metanotal spine marked as a tubercle; propodeal lateral carinae inverted Yshaped, shafts distinctly curved outward; propodeal lateral and plical areas obscured by pale, dense setae, setal bases pustulate, marginal striation not extending medially; posterior propodeal projection indistinct; fore wing slightly wider than mesoscutum (TSL/WW =0.81–0.98, m=0.89, SD =0.05); marginal vein about 3 times as long as stigmal vein (m/st =2.80–3.10, m=2.94, SD =0.10); hind wing about two times as wide as marginal cilia length (HWW/HWS =2.00–2.15, m=2.02, SD =0.05).

T1, less than 1.5 times as wide as T1+T2 length (T1W/T1+T2L =1.03–1.30, m=1.18, SD =0.08); T3 about 1.5 times as wide as long (T3W/T3L =1.40–1.70, m=1.55, SD =0.08), as wide as mesoscutum (T3W/ TSL =0.93–1.08, m=0.99, SD =0.04); costae on T3 reaching middle of tergum medially; lateral patch distinct, reduced; diameter of posterior patch of T3 nearly equal to width of one basal depression; lateral patch on T4 present, median patch marked by punctures.

MALE (n=4): FCI =1.22–1.25 (m=1.23, SD =0.01); HW/IOS =1.48–1.48, (m=1.48 SD <0.01); A1/r =4.75– 4.87 (m=4.78, SD =0.06); A5 not modified, A2–A6 unibottled, A7–A11 dibottled, flagellomeres with numerous ventral microcilia ventrally; TSL/WW =0.68–0.75 (m=0.71, SD =0.04);

Diagnosis. Most closely related to X. laticeps , differing by absence of vertex patch, numerous ventral microcilia on male flagellomeres, granulose mesoscutum of females, presence of netrion sulcus, more elongated fovea of mesepimeral sulcus and reduced metanotal spine.
