Stenoleon cingulatus New 1985c: 17 . Holotype male, Carnarvon , Queensland, Nov. 1944, N. Geary (AMSA).

Description. Adult: body 20 mm, forewing 22 mm, hindwing 20 mm. Coloration: body dark brown to black; face yellow; frons narrowly black below eyes; interantennal space and all of dorsal head dark grayish brown; antenna dark brown, much of scape yellow; apices of flagellomeres narrowly pale brown; pronotum with trace of narrow median stripe, anterior angles narrowly ivory; partial weakly indicated dorsolateral streak; abdomen dark, posterior of tergites II-VIII very narrowly pale brown; forewing without extensive spotting in basal one-half in contrast to apical one-fifth; longitudinal veins predominantly dark brown, subcosta with intermediate pale areas; crossveins at base of wing dark brown, then with alternating bands of white and brown to give wing a banded appearance; pterostigma pale; rhegma with weak grayish brown shading; legs with femur dark brown, foretibia mostly dark brown, hind tibia pale brown except black apex; tarsomeres I, II, and V partially black, tarsomeres III and IV black. Chaetotaxy: forefemur and foretibia with white bristles; hindtibia with black bristles. Structure: antenna as long as one-half length of forewing, filamentous without club; vertex not raised; pronotum about as long as broad; foretibial spurs reach to apex of tarsomere II; wings slender, rather tapered; legs long and slender, tibial spurs slender, extending to apex of basitarsus; pretarsal claws slender, longer than tibial spurs; male abdomen with deep ectoprocts; sternite IX broad, apex transverse; gonarcus shallow, broadly rounded; parameres linked medially, deep and rounded posteriorly.

Larva: head somewhat longer than wide, with prominent dorsal median dark brown stripes, ventral side nearly all pale brown except for anterior dark brown spot ( Figure 83); mandibular middle tooth reddish brown, slightly longer than distal tooth; mesothoracic spiracle borne on long tubercle; abdomen with abundant dark brown areas not especially limited to midline.

New records. AUSTRALIA. Queensland: Slaty Creek , 21 km south Flinders Highway, 9. IX. 2005, R. Miller, & L. Stange (reared) (2m, 9f, FSCA; TAMU) ; Highway 781 to Malbon , 8. XII. 1989, R. Miller (2 larvae in Guano, reared) (2m, 2f, FSCA) ; 21 km. south Barkley Highway, 13 km. west Cloncurry , 8.XII.1989, R. Miller (reared) (2f, FSCA) .

Discussion. The adults are structurally very similar to S. fieldi Tillyard. The wing pattern is similar to S. fieldi but that species has many more dark brown markings especially in the basal half of the wing. The antennae of both species are identical in length and lack of apical club. The tibial spurs are longer than in S. fieldi .
