Description

Length: males 8–9.5mm, females 10–12mm; body convex in profile, length c. 2.7x height. Body and appendages brownish- or reddish-yellow, except (i) elytra and antennomeres 2–11 black, with dark blue reflection; (ii) tarsi, apices tibiae, dark brown with green reflection; (iii) middle of abdominal ventrites I–IV sometimes brown or black, apices mandibles brown.

Head ( Figs 5, 21): head puncturation variable, usually sparse and fine on middle and frontoclypeus, stronger and closer at sides, but may be strongly and closely punctured throughout vertex; depressed between eyes, without deep grooves at sides of depression, with groove on midline of vertex; eyes separated by c. 3.7x eye widths (male) or c. 4x eye widths (female); gena c. 0.4x eye length (both sexes); antennae c. 4x socket diameters apart; antennae c. 0.8–85x body length (male), or c. 0.7x body length (female); all antennomeres elongate: 2 shortest (c.0.5x first), <3, <1, <4=10, <5=6=8=9=11, <7 (male), female similar; labrum not densely setose, with 2 pairs of prominent setae; apical maxillary palpomere elongate, almost cylindrical in both sexes, preapical palpomere shorter than apical.

Thorax ( Figs 5, 47): pronotal puncturation variable in size and density, generally sparse and fine, with larger punctures at base, shining, with scattered distinct micropunctures between macropunctures; pronotal width 1.6x length, with strongly developed convex lateral lobes at middle; pronotal disc with pair of deep lateral depressions, with or without shallow basal depression; anterior margination complete or effaced at midline; hypomeron at least partly punctate; prosternal process narrow and strongly arched from base to truncate apex; scutellum punctured at sides and base, elongate-triangular with blunt apex; elytron with 2 circular deep depressions on basal half of disc, one on striae 4–5, and one on striae 6–8; elytral punctures strong and deep, finer towards apex; elytra striate, with striae 1–6 regular and 7–9 partially obliterated by deep elytral depressions and large interstrial punctures; 1–2 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 narrow, strongly arched to truncate apex; metaventrite shining and sparsely and minutely punctured, anterior with complete margination and without median depression, edge slightly pitted lateral to middle; metepisternum microreticulate, strongly punctured; 1 short spur on protibia, 2 on remainder. Abdomen ( Figs 69, 83, 101, 116): ventrites I and II fused (not completely in male: some movement at middle); ventrites I–V smooth and shining, not microreticulate, moderately closely and strongly punctured on apical half of I–II, and most of III–V, males less punctate or impunctate along midline; short recumbent pubescence on each ventrite; ventrite I laterally keeled along basal 1/3–2/3, other ventrites without keels; apex ventrite V narrowly truncate in both sexes; sternite VIII of male Y-shaped; penis slightly mucronate in dorsal view, tip slightly curved and thickened in lateral view; female sternite VIII with elongate-triangular basal apodeme; gonocoxite distinctly setose; spermatheca hook-shaped, with densely coiled duct.

Notes

Macrolema atripennis is known from a few moderately elevated localities at or near the border of New South Wales and Queensland, from Mount Warning to Mount Tamborine ( Fig. 134). The specimen from north Queensland is probably mislabelled. Cooktown is far from the nearest locality and the specimen comes from a collection (H. W. Brown) with many problematic labels (pers. obs., CAMR; see also under M. quadrivittata ). 20 specimens were collected, from November to February. The single specimen collected on Ficus was not feeding.
