Description  
Length: male 8mm, female 11.5–12mm; body elongate parallel-sided, length c. 3x width, length c. 4x height, slightly elevated to elytral base in profile, with anteriorly convex pronotum. Body and appendages yellowishbrown to orange, except: disc of pronotum and antennomeres 5–6 darker in male; elytra green with vaguely defined lateral yellow or pale yellow stripe from humerus along side margin (including base of epipleuron) to before apex (only basal half in male); antennomeres 7–11 dull red, darker in male); head dorsal to antennal sockets, extreme edges pronotum and anterior face apical half metafemora dark reddish-brown; apices mandibles, labrum (one female only) black or blackish-brown; bases of tibiae slightly reddish. Head and pronotal punctures each armed with recumbent short white setae. Head microreticulate, pronotum and elytra shining, without microreticulation.  
Head: pubescent throughout, setae dense, short and recumbent, sparser on clypeus and above antennae; puncturation fine and dense (interspaces <diameters), slightly sparser but larger on clypeus; midline of head shallowly depressed, sides of frontoclypeal suture not deeply grooved; eyes large and laterally prominent, with small internal canthus, separated by 4x (male) or 4.3x eye width (female); temples short, c. 0.1x length eye, not posteriorly truncate; gena 0.3x (male) or 0.4x eye length (female), genal lobe ratio 1.2–1.3; antennae situated at anterior of head, in laterally directed sockets, c. 4x socket diameter apart, 0.75x (male) or 0.6x body length (female); all antennomeres elongate: 2 shortest, 0.5 (male)–0.65x (female) first, <3, <4, <1, <6, <5, <8, <7, <10, <9, <11 (male), or <1=3=4, <6, <5, <8=10, <9, <7, <11 (female); antennomere 7 distinctly expanded; labrum not densely setose, but with 2–3 pairs of prominent setae on disc and 3 pairs at apical margin; apical maxillary palpomere fusiform, with narrow tip in female, broader in male, preapical as long as apical (female), or shorter (male); mentum strongly transverse, width 3x median length, with prominent anterior angles; gula distinctly transversely grooved.  
Thorax: pronotum pubescent throughout with dense recumbent setae, except basal 2/3 of midline, hypomeron densely setose throughout; pronotum with convex sides, broadest at middle (male and one female) or basal 2/3 almost parallel-sided, anterior truncate, base medially convex; pronotal width c. 1.3x length; anterior angles strongly laterally produced, c. 60°, posterior angles feebly laterally produced, c. 100°; anterior and posterior not margined except near angles; lateral margination strong and even; sides of disc feebly depressed in basal half, with slight swelling laterally; pronotal midline impunctate for basal 2/3, remainder of pronotum including hypomeron finely (but punctures variable in diameter) and densely (as head) punctured, especially on small oval median patch anterior to middle, punctures larger and sparser on sides of disc, coalescent and rugose at sides and on hypomeron; prosternum laterally sparsely punctured and pubescent, process almost glabrous and impunctate but with row of setae at sides; prosternal process elongate, medially grooved in apical half, almost parallel sides slightly expanded to strongly bilobed apex, angle between lobes V-shaped, c. 45°; scutellum impunctate, quadrate with rounded apex (male), or semi-ovate (female), flat; elytron glabrous (except sparse erect setae at extreme apex), without oval depression between humerus and epipleuron; sculpture almost uniform, punctures large and close (separated by 1–3 diameters), shallower at base and apex, interspaces with scattered minute punctures and shallow transverse grooves, apical 1/6 more sparsely punctured and weakly wrinkled; upper margin epipleuron reaching angle of humerus at base, absent at apex; mesoventrite median process gradually elevated to strongly bilobed apex, angle between lobes V-shaped, c. 90°; wing fully developed, with uncoloured or faintly yellowish medial fleck; metaventrite shining and glabrous medially, at sides densely pubescent, laterally strigose and finely punctured, apical lobe not margined, flat or medially depressed; metepisternum densely finely punctured and pubescent; 1 short spur on protibia, 2 on remainder; tarsi narrow, length first metatarsomere 2x width; length second metatarsomere 1.3x width.  
Abdomen: ventrites I and II entirely fused; ventrites shallowly microreticulate, mostly smooth and shining at middle, with dense minute setae and punctures at sides, I–II with denser patches of fine punctures and V with longer more erect setae and larger punctures; ventrites I–V almost entirely laterally keeled in male, I–II and base of IV keeled in female; apex ventrite V truncate (female) or shallowly concave (male).  
 Genitalia: spiculum relictum transversely rectangular, with shallowly concave apical margin and minute asymmetric spiculum at base; penis thick, with large basal foramen (0.6x penis length), apex rounded but concave at tip in dorsal view, acute and straight in lateral view; ostium of penis without sclerites; base of tegmen with semicircular median ridge; endophallic sclerite strongly developed, not exerted in repose; apex female sternite VIII almost truncate, basal apodeme large and transverse, apex strongly expanded; median sclerite thin; gonostylus ovoid, not fused to gonocoxite; spermatheca falcate, with swelling near base, duct short and thick with ovoid swelling before insertion of gland; rectal kotpresse similar to B. xaracuu (Fig. 148), with dense elongate ventral spinule patch and strips of dense spinules dorsally.   
Notes  
Etymology: from the type locality, Mandjelia, a noun in apposition. This is the standard spelling of the type locality.  
 Bohumiljania mandjelia is similar in colour, size and surface sculpture to B. tango. While the sample of these species is small (one male and two females of B. mandjelia, one female of B. tango), we feel the sum of small differences is significant, including: pronotal anterior and posterior angle shapes, prosternal process sculpture, elytral sculpture (apical punctures, setae, area between humerus and epipleuron), lateral keeling of ventrites, swelling of spermathecal duct.   
 Bohumiljania mandjelia is only known from the vicinity of Mandjelia, a hill of moderate elevation in NW New Caledonia. The species has been collected there from three localities, at 580–780m altitude. Specimens were collected at mv light and by beating, in December. The published record of B. humboldti from Mandjelia may refer to this species (Jolivet et al. 2005). If so, the hostplant is Metrosideros laurifolia (Myrtaceae) (loc. cit.).
