Figure 85  
 FEMALE (Holotype): Length= 1.50 mm.   
Dark brown; head, mesonotum blackish; mandible, interantennal process, radicle, trochanteres, tibiae and tarsi, except light brown apical tarsomeres, yellow; coxae, femora, antenna light brown.  
 FCI =1.13; LCI =1.70; HW/IOS =1.59; head less than 1.5 times as wide as mesosoma (HW/TSL = 1.28); facial striae not reaching midlevel of eye along inner orbit, exceeding and partly obscuring frontal patch; frontal patch distinct, not vertically elongated, not reaching eye midlevel; frons setae sparse, thin; central keel incomplete, not reaching eye midlevel; toruli triangle shorter than clypeus height; POL about as long as OOL (POL/OOL =0.93); OOL more than 1.5 times as long as LOL (OOL/LOL =1.66); hyperoccipital carina present, blunt, not extending to inner orbit; vertex reticulate; genal patch present, merging with vertex sculpture; A1 more than 5 times as long as radicle (A1/r =5.33), nearly equal to clava (A1/cl =0.96).   
 Epomial carina present, diminishing medially; cervical pronotal area smooth, with scattered setae, setal bases pustulate; lateral pronotal area near epomial carina finely coriaceous, above pronotal ventral projection crenulate; netrion sulcus complete; netrional sculpture not extending onto lateral pronotal area; pronotal suprahumeral and cervical sulci complete, foveolate, pronotal suprahumeral sulcus strongly diminishing medially; mesoscutum less than 1.5 times as wide as long (TSL/ML =1.34); notaulus normal, almost reaching transscutal line; reticulate sculpture of mesoscutum extending to lateral and inter notaular areas, more transverse on internotaular area; mesoscutellum less than 2 times as wide as long (SW/SL =1.87); scutoscutellar sulcus slightly diminishing medially, 1.5–2 times as wide laterally as in the middle; mesoscutellum crenulate anteriorly, with sparse, marginal setae; posterior scutellar sulcus 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 2–3 times as wide as foveae width of postacetabular sulcus; mesopleural carina complete, with complete rows of foveae; sulcus along metapleural carina foveolate; metascutellum sharply pointed; propodeal lateral carinae inverted Y-shaped, shafts slightly curved outward; propodeal lateral area and plical area obscured by pale, sparse setae, marginal striation extending medially; posterior propodeal projection distinct; fore wing distinctly wider than mesoscutum (TSL/WW =0.83); marginal vein more than 3.5 times as long as stigmal vein (m/st =3.46); hind wing about 3.5 times as wide as marginal cilia length (HWW/HWS =2.20).   
 T1 with small hump anteriorly, less than 1.5 times as wide as T1+T2 length (T1W/T1+T2L =1.12); T3 less than 1.5 times as wide as long (T3W/T3L=1.26), as wide as mesoscutum (T3W/TSL =1.07); costae on T3 exceeding level of apical setae; lateral patch distinct, extending medially almost as wide as long diameter of posterior patch of T3 equal to width of 2–3 basal depressions; posterior T3 without coriaceous sculpture; anterior half of T4 entirely reticulate.   
 MALE: Unknown   
 Diagnosis. Most closely related to X. feehani, differing in anteriorly crenulate mesoscutellum, color of coxae, extension of lateral patch on T3, sculpture of posterior T3.   
 Etymology. Named after the type locality.   
 Material examined. Holotype female: MALAWI: Central Region, Kasungu District, Mtunthama, 16.II.1983, J.Feehan, FIT [CMNH:####].   
Holotype is deposited in CMNH.
