MALE (Holotype): Length= 0.79 mm.

Brown, interantennal process, radicle, A1, A2 entirely, A3–A12 apically, legs including coxae excluding hind tibia and hind tarsomeres yellow.

FCI =1.17; LCI =1.43; HW/ IOS=1.53; head less than 1.5 times as wide as mesosoma (HW/TSL = 1.29); facial striae not extending to frons; frontal patch distinct; frons setae sparse, thin; central keel absent; toruli triangle opened dorsally, shorter than clypeus height; POL less than two times as long as OOL (POL/ OOL =1.75); OOL longer than LOL (OOL/LOL =1.33); hyperoccipital carina absent; vertex patch present, with diameter equal to lateral ocellus, not reaching lateral ocellus; interocellar area reticulate posteriorly; genal patch present, separated from vertex sculpture; A1 about 5 times as long as radicle (A1/r =4.88); A3– A11 unibottled; A5 modified.

Epomial carina present, diminishing medially; cervical pronotal area smooth medially, reticulate dorsolaterally just dorsal to epomial carina; lateral pronotal area reticulate dorsomedially near and above epomial carina; netrion sulcus incomplete, netrion striation extending to lateral pronotal area; pronotal suprahumeral sulcus diminishing medially, not foveolate; pronotal cervical sulcus foveolate; mesoscutum less than 1.5 times as wide as long (TSL/ML =1.30); notaulus elongate, exceeding transscutal line; mesoscutum with sparse, thin setae; mesoscutum sculpture extending to lateral and internotaular areas, not reaching posterior margin; mesoscutellum about 1.5 times as wide as long (SW/SL =1.66); scuto-scutellar sulcus distinctly diminishing medially, 4 times as wide laterally as in the middle; mesoscutellum smooth with sparse, long, thin setae; posterior scutellar sulcus extending onto axillula; sternaulus distinctly separated from anterior row of foveae of mesopleural carina; distance between postacetabular sulcus and anterior row of foveae of mesopleural carina 2–3 times as long as foveae width of postacetabular sulcus; mesopleural carina incomplete, anterior and posterior rows of foveae diminishing ventrally; sulcus along metapleural carina foveolate; metascutellum unarmed; propodeal lateral carinae inverted V-shaped, shafts straight; propodeal lateral area and plical area bare; marginal striation extending medially; posterior propodeal projection indistinct; fore wing wider than mesoscutum (TSL/WW =0.84); marginal vein more than 3 times as long as stigmal vein (m/st =3.66); hind wing less than 1.5 times as wide as marginal cilia length (HWW/HWS =1.25).

T1 almost as wide as T1+T2 length (T1W/T1+T2L =1.10); T3 about as wide as mesoscutum (T3W/ TSL =1.11); basal depressions absent on T3; lateral patch absent; diameter of posterior patch of T3 shorter than width of basal depression on T2; lateral patch on T4 present, median patch absent.

FEMALE: Unknown.

Diagnosis. Differs from all other species of Xenomerus by the combination of smooth T3, extended netrion sculpture, and well-separated and developed sternaulus.

Etymology. The species name refers to the collector, John S. Noyes (BMNH).
