description: Barryfilius lewisae (Britton, 1978), new combination
(Figs. 16, 22, 25)
Lepidiota lewisae Britton, 1978: 67, figs. 203–205 (aedeagus), fig. 282E (head and pronotum).
Type series. Holotype male in QM: Mount Lewis, via Julatten, N. Qld. [16.57°S, 145.28°E], 3,500-4000’ [feet], 27–28.xi.1965, G. Monteith (examined).
Diagnosis. Male. Body 22 mm long; dark red-brown, pronotum darker than elytra (Fig. 16). Terminal palpomere of maxillary palp large, 1 mm long, elongate-elliptical (length:width 3.3:1), with a large, flat, dull, elliptical depression on dorsal side. Clypeus with anterior face moderately deep, width 5x length; upper surface transverse, width 2.7x length, anterior margin slightly indented in middle, with rounded angles; upper surface strongly concave, densely punctured, each of the broad, flat-bottomed punctures with a flattened, white seta about as long as radius of the puncture. Frons irregularly and coarsely punctured, each puncture with a short, white seta as long as the radius of the puncture; posterior quarter with only a few punctures and setae; antero-laterally without longer setae above each eye. Antennae with 10 antennomeres, antennomere 3 elongate-cylindrical, antennomere 4 discoidal, antennomeres 5–7 each with a very short indication of a lamella, antennomeres 8–10 lamellate, 2.8–2.9 mm long. Pronotum transverse, greatest width 16x length; anterior margin narrow, continuous and raised, punctate except in middle; lateral edges with a rounded, obtuse angle in middle, straight before and after angle; posterior margin with a narrow, raised margin, slightly obliterated in the middle and towards posterior angle; anterior and posterior angles slightly obtuse; surface uniformly punctured (approximately 6–8 mm-2), denser towards anterior edge, especially in middle and in angles, each puncture with a minute slightly elongate, white seta about as long as diameter of the puncture. Scutellum with a line of small punctures close to lateral edge in anterior third, disc sparsely punctured with setae as on pronotum. Elytra sparsely but fairly uniformly punctured (approximately 10 mm-2) except on sutural interval, each puncture with a stout, acutely pointed, white seta as long as those on pronotum. Propygidium with a few scattered punctures with short setae. Pygidium similarly punctured; setae short but more elongate than on elytra, surface between punctures microreticulate, long, yellow setae on posterior-lateral margins. Ventral surface of thorax densely clothed with long, fine, yellow setae; pronotal hypemeron also with elongate, white setae. Teeth on outer edge of protibia rounded. Ventrites clothed with short, setae similar to pygidium, sparser on posterior ventrites; first visible ventrite with longer, yellow setae; penultimate ventrite with a few, scattered, long, yellow setae near posterior margin; terminal ventrite without lateral lobes. Aedeagus slightly asymmetrical, apices rounded in dorsal view (Fig. 22).
Female. Unknown.
Distribution (Fig. 25). Known only from Mount Lewis northwest of Julatten, an isolated massive south of the Windsor Tableland where B. contigua occurs.
Natural history. The type was taken in late November (Britton 1978).
