(Figs 7, 23, 49, 71, 85, 131)  
Material examined Type: Holotype: male: /Bowen Queensland A. Simson / 2756/ [SAM].  
Description [male only]  
Length: male 11mm; body moderately convex in profile, length c.3x height. Body and appendages brownish-yellow, except (i) elytra except all margins, dorsal half first and all of other antennomeres, outer edge and apices of tibiae, tarsomeres except edges, apices mandibles, median elongate mark on vertex, black with dark blue reflection.  
Head (Figs 7, 23): head closely punctured throughout, more finely and closely on frontoclypeus, more coarsely on remainder; depressed between eyes, with 2 small grooves, and long deep groove on midline of vertex; eyes separated by c. 3.5x eye widths; gena c. 0.22x eye length; antennae c. 5x socket diameters apart; antennae c. 0.75x body length (male); all antennomeres elongate: 2 shortest (c. 0.6x first), <3, <1, <4=5=6=8=9, <7; labrum not densely setose, with 2–3 pairs of prominent setae; apical maxillary palpomere elongate, almost cylindrical, preapical palpomere slightly shorter than apical.  
Thorax (Figs 7, 49): pronotum sparsely and strongly punctured at sides and base, more diffusely on anterior half of disc, shining, with scattered distinct micropunctures between macropunctures; pronotal width 1.45x length, with strongly developed convex lateral lobes at middle; pronotal disc with pair of shallow lateral depressions, with small shallow basal depression; anterior margination incomplete, absent on median third; hypomeron strongly punctate; prosternal process narrow and strongly arched from base to truncate apex; scutellum impunctate, elongate-triangular with blunt apex; elytron without obvious depressions on basal half of disc; elytral punctures strong throughout, both interstrial and strial, and elytra not obviously striate, with strial punctures in irregular lines; without deep irregular depressions along basal half of elytron adjacent to epipleuron; upper margin epipleuron reaching base of elytron, but not continued on basal edge; mesoventrite median process strongly arched to truncate apex; metaventrite shining and sparsely and minutely punctured, anterior with complete margination and without median depression, edge pitted lateral to middle; metepisternum not microreticulate, strongly punctured; 1 short spur on protibia, 2 on remainder.  
Abdomen (Figs 71, 85): ventrites I and II entirely fused; ventrites I–V smooth and shining, not microreticulate, moderately closely and strongly punctured and pubescent throughout, without obvious setose bands on each ventrite; ventrite I laterally keeled along basal 2/3, other ventrites without lateral keels; apex ventrite V convex; sternite VIII of male Y-shaped; apex of penis mucronate in dorsal view, thickened and recurved in lateral view.  
Notes  
The species name is from the indigenous language of the people inhabiting the type locality (Horton 1996): a noun in apposition.  
 Macrolema giya is known from the holotype, collected in the vicinity of Bowen, north Queensland (Fig. 131), before 1919, when A. Simson died (Musgrave 1932). The single specimen is missing antennomeres 10– 11 and hind tarsomeres 3–5.
