 FEMALE (Holotype): Length= 0.96 mm.   
Dark brown; mandible, interantennal process, radicle, A1 proximally, trochanters, tibiae, tarsomeres except dark brown apical tarsomeres, light brown.  
 FCI =1.18; LCI =1.61; HW/IOS =1.51; head less than 1.5 times as wide as mesosoma (HW/TSL = 1.32); facial striae not reaching midlevel of eye along inner orbit, not exceeding frontal patch; frontal patch distinct, vertically elongated, reaching eye midlevel; frons setae sparse, thin; central keel incomplete, not reaching eye midlevel; toruli triangle shorter than clypeus height; POL less than 1.5 times as long as OOL (POL/ OOL =1.46); OOL almost 1.5 times as long as LOL (OOL/LOL =1.44); hyperoccipital carina present, blunt, not extending to inner orbit; vertex reticulate; genal patch present, separated from vertex sculpture; A1 more than 6.0 times as long as radicle (A1/r =6.50), shorter than clava (A1/cl =0.82).   
 Epomial carina present, diminishing medially; cervical pronotal area smooth, with scattered setae; lateral pronotal area near epomial carina reticulate, with few crenulae above pronotal ventral projection; netrion sulcus complete; netrion sculpture not extending onto lateral pronotal area; pronotal suprahumeral and cervical sulci complete, foveolate; mesoscutum less than 1.5 times as wide as long (TSL/ML =1.34); notaulus normal, reaching transscutal line; reticulate sculpture of mesoscutum extending to lateral and internotaular areas; mesoscutellum less than 2 times as wide as long (SW/SL =1.88); scuto-scutellar sulcus distinctly diminishing medially, 4 times as wide laterally as in the middle; mesoscutellum smooth, with sparse 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 3–4 times as wide as foveae width of postacetabular sulcus; mesopleural carina complete, with complete anterior row of foveae, posterior row of foveae strongly diminishing and reduced posteroventrally; sulcus along metapleural carina not foveolate; metascutellum sharply pointed; propodeal lateral carinae inverted Vshaped, shafts slightly curved outward; propodeal lateral and plical areas obscured by pale, sparse setae, marginal striation extending medially; posterior propodeal projection distinct; fore wing wider than mesoscutum (TSL/WW =0.85); marginal vein less than 3.5 times as long as stigmal vein (m/st =3.2); hind wing two times as wide as marginal cilia length (HWW/HWS =2).   
 T1 concave dorsally, about 1.5 times as wide as T1+T2 length (T1W/T1+T2L =1.47); T3 1.5 times as wide as long (T3W/T3L=1.5), wider than mesoscutum (T3W/TSL =1.125), costae on T3 exceeding middle of tergum, not exceeding apical setae; lateral patches distinct, 3–4 times as long as wide; diameter of posterior patch of T3 nearly equal to width of one basal depression; posterior T3 without coriaceous sculpture; lateral and median patches present, not fused.   
 Variability (n=10): Length= 0.96–1.32 mm (m=1.04, SD=0.12); head, mesosoma and metasoma black in larger specimens; FCI =0.98–1.18 (m=1.14, SD=0.06); LCI =1.50–1.67 (m=1.58, SD=0.05); HW/IOS =1.44– 1.57 (m=1.51, SD=0.04); HW/TSL =1.26–1.35 (m=1.36, SD=0.04); in smaller specimens facial striae extending along inner orbit near orbital patch; in larger specimens central keel almost reaching median ocellus POL/OOL =1.38–1.58 (m=1.47, SD=0.08); OOL/LOL =1.23–1.44 (m=1.35, SD=0.07); in larger specimens from Uganda vertex sculpture indistinct; A1/r =5.5–6.7 (m=6.27, SD=0.4); A1/cl =0.84–0.92 (m=0.88, SD=0.02); TSL/ML =1.33–1.42 (m=1.36, SD=0.03); SW/SL ==1.76–1.88 (m=1.83, SD=0.05); in larger specimens anterior row of foveae of mesopleural carina present posteroventrally TSL/WW =0.82–0.92 (m=0.86, SD=0.03); m/st =3.26–3.32 (m=3.28, SD=0.05); HWW/HWS =1.92–2.16 (m=2.05, SD=0.08); T1W/T1+T2L =1.4–1.56 (m=1.45, SD=0.05); T3W/T3L =1.42–1.54 (m=1.47, SD=0.04); T3W/TSL =1.12– 1.26 (m=1.17, SD=0.05), in larger specimens costae extending to lateral patch on T3.   
 MALE: Unknown.   
 Diagnosis. Most closely related to X. feehani, differing by POL/OOL, extension of frontal patch and facial striae, sculpture of posterior T3, color of coxae, reduction of posterior row of foveae of mesopleural carina and foveolate sulcus along metapleural carina.   
 Etymology. Named after Béla Kalocsa, who was the first teacher in biology of the senior author.
