HOLOTYPE ♁: Queensland: 6km N Taroom, Qld , 25°36′S 149°46′E, 1 Oct 1991, 200m, G. Daniels, mv lamp ( QM, type reg. T258559) . PARATYPE (1): QLD: 24°49′Sx149°45′E Brigalow Res.Stn. site 2. 13Oct2001 Pyrethrum Monteith. Burwell. 170m brigalow trunks 10222 (1 ♀, QM) .

Diagnosis. Pronotum sub-tuberculate laterally, disc smooth, punctation mostly seta-associated; elytra dark with orange fasciate and apical maculations fasciae positioned posterior of elytral mid-length (humeral maculae absent), fasciae meeting at the suture, punctation lacking nodules, 8 th stria beginning half way between base and fascia, striae 1–9 complete to apical maculae, stria 10 ending just before apical macula; femora yellow basally, brown apically (<half of profemora, about one-third of other femora brown); tarsi with three ventral tarsal pads.

Description. Habitus: Fig. 180 . Total length: 10.4 mm. Head: Cranium black, clypeus and supra-antennal elevations infused with reddish-black, anteclypeus semi-transparent orange, antennae, labrum and palpi orange to orange-brown; eyes separated by 0.62 eye widths; vertex with small punctures and fine transverse wrinkles basally and heavier punctation towards frons, frons with scattered punctation, heaviest laterally, least dense above clypeus, surface without conspicuous sulcate or elevated areas; genae and submentum wrinkled; exterior margins of terminal palpomeres about 1.8 times (maxillae) and 2.8 times (labium) the length of inside edges; antennae almost reaching base of pronotum; entire frons with fine pale medially-directed setae. Prothorax: Black, venter infused with deep reddish hue; pronotum 1.3 times longer than wide, sides sub-tuberculate, middle about as wide as pronotal arch; subapical depression deeply v-shaped, tapered towards a short deep central sulcus, lateral sulci obscure, disc smooth, punctation mostly seta-associated; numerous short fine multi-directional setae and occassional very long erect setae. Pterothorax: Black infused with reddish hue, vested with numerous short and occasional long setae; elytra blackishbrown with orange markings (each elytron with an apical macula and a transverse fascia just posterior of the elytral mid-length); length to width ratio 3.17:1; 8 th stria beginning half way between base and fascia, striae 1–9 reaching apical macula, tenth stria ending just before apical macula, punctation lacking internal nodules, basal punctation almost twice the diameter of those posterior of fascia, epipleurae extending to apical maculae, interstriae smooth, less than width of basal punctation, about as wide as corresponding punctations posterior of fascia, interstriae with fine short semi-erect setae (often> 1 per puncture) and longer erect setae (often 1 per every 2 punctures). Legs: Coxae brownish, slightly more than basal half of profemora and about basal two-thirds of meso- and metafemora yellow, slightly less than apical half of profemora and about apical one-third of meso- and metafemora dark brown, tibiae and tarsi pale brown, ventral tarsal pads yellowish; profemora very slightly swollen, other femora slender. Abdomen: Ventrites orange. Male genitalia: Tegmen ( Fig. 65 ) slender, widest at bend of tegminal arms, evenly tapering towards parameroid lobes, the latter more heavily sclerotised and apparently associated with an internal frame-like structure, dorsal sinus short, about one-fifth tegmen length, narrow, ventral sinus about as long or slightly shorter, apodeme about one-quarter tegmen length, broadly spatulate at base; median lobe ( Fig. 101 ) with apical thread-like process; pygidium as in Fig. 137 .

Etymology. The specific epithet gracile (Latin, meaning slender) refers to the long slender body shape of this species.

Biology. One specimen was collected at light (m. v. lamp ), the other by pyrethrum knockdown on brigalow trunks; both in October.

Distribution (Map 2). Platynotum gracile sp. nov. is known only from two localities, one just north of, the other just south of, Isla Gorge National Park, south-central Queensland.
