Material examined Type Holotype: female/ Mt Do, 1000m, summit forest, 27.x.1978, J. S. Dugdale / diurnal/ (LRL).  
Description [female only]  
Length: female 15.5mm; body elongate parallel-sided, length c. 2.8x width, length c. 3.4x height, flat at elytral base in profile, with slightly convex pronotum. Body and appendages dark reddish-brown, except: elytra green with small yellow humeral spot and lateral yellow stripe from humerus broadly along side margin (excluding base of epipleuron) to apex, including apex of suture, remainder of suture narrowly reddish-brown; midline of venter olive-brown; sides of venter and middle of femora slightly bronzed; antennae reddish-orange; labrum and palpi yellow; tarsi entirely dull yellow; apices of mandibles and edge of buccal cavity at antennal sockets black. Head and pronotal punctures each armed with recumbent short yellowish setae. Head, pronotum and elytra shining, without microreticulation.  
Head: pubescent throughout, setae dense, short and recumbent, sparser at middle; puncturation fine and dense, interspaces </= puncture diameters, slightly sparser along midline and dorsal to antennae; midline of head deeply depressed, sides of frontoclypeal suture deeply grooved; eyes large and laterally prominent, with small internal canthus, separated by c. 4.1x eye width (female); temples short, c. 0.2x length eye, not posteriorly truncate; gena c. 0.25x eye length (female), genal lobe ratio 1.4; antennae situated at anterior of head, in laterally directed sockets, c. 4x socket diameter apart, c. 0.5x body length (female); all antennomeres elongate: 2 shortest (c. 0.5x first), <3, <4=6, <1=5, <8, <10, <7=9, <11 (female); antennomere 7 (female) distinctly expanded; labrum not densely setose, with 1 pair of prominent setae on disc and 3 pairs at apical margin; mentum transversely rectangular, width c. 2x median length, without prominent anterior angles; apical maxillary palpomere fusiform, with broad tip, preapical slightly shorter than apical (female); gula distinctly transversely grooved.  
Thorax: pronotum pubescent throughout with dense recumbent setae, except in apparently worn off patches and on elevated parts of midline and lateral edges, hypomeron densely setose throughout; pronotum almost parallel-sided, anterior truncate, base medially strongly convex; pronotal width c. 1.15x length; anterior angles laterally produced, c. 85°, posterior angles slightly produced, c. 90°; anterior and posterior not margined except near angles, margination of sides obscured by elongate ridges and grooves; sides of disc longitudinally broadly and irregularly depressed in basal half, with a swelling laterally and groove between swelling and impunctate and ridged lateral edge; pronotal midline slightly elevated in basal half and in a circle anterior to middle, elevated areas impunctate; remainder of pronotum including hypomeron finely and densely punctured, as head, punctures larger and sparser on sides of disc, coalescent and rugose at sides and on hypomeron; prosternum closely punctured and pubescent at sides, process smooth, with scattered punctures but almost glabrous; prosternal process elongate, medially grooved in apical half, straight sides slightly expanded to strongly bilobed apex, angle between lobes V-shaped, c. 100°; scutellum impunctate, quadrate with rounded apex, flat; elytron glabrous (except minute setae at extreme apex), without groove between humerus and epipleuron, sculpture uniform, fine and scattered punctures, without shallow grooves between punctures; upper margin epipleuron reaching angle of humerus at base and complete to apex; mesoventrite median process abruptly elevated to strongly bilobed apex, angle between lobes U-shaped, c. 80°; wing fully developed, with pale yellowish medial fleck; metaventrite shining and glabrous medially, at sides densely pubescent, laterally strigose and finely punctured, apical lobe not margined, flat; metepisternum densely finely punctured and pubescent; 1 short spur on protibia, 2 on remainder; tarsi moderately broad, length first metatarsomere 1.5x width; length second metatarsomere 1.2x width.  
Abdomen: ventrites I and II entirely fused; ventrites shallowly microreticulate, mostly smooth and shining at middle, with dense recumbent setae and punctures at sides, I–II with denser patches of fine punctures and V with longer more erect setae; ventrite I almost entirely laterally keeled, II keeled in basal 2/3, III–V without lateral keels; apex ventrite V truncate (female).  
Genitalia: apex female sternite VIII truncate, basal apodeme quadrate, but apex strongly expanded; gonostylus ovoid, not fused to gonocoxite; median sclerite elongate, narrow; spermatheca falcate, duct short and thick, twisted before insertion of gland; rectal kotpresse with dense elongate ventral spinule patch and strips of dense spinules dorsally.  
Notes  
Etymology: named for the Xaracuu people, indigenous to the Mount Do area (Anonymous 2010), a noun in apposition.  
 Bohumiljania xaracuu is known from a single locality, the summit of Mt Do, SE New Caledonia, altitude 1000m. An attached label notes that the specimen was ‘diurnal’. The hostplant is unknown.
