Description Male. Body length , 25.26 mm ; width, 5.41 mm . Colour (Fig. 53). Body reddish brown with head, thorax, and basal and apical elytra darker. Head, pronotum and elytra covered with fairly dense, more or less evenly distributed, whitish pubescence; pubescence on elytra generally shorter. Head. Postclypeus subtriangular and flattened, with fairly dense coarse punctures; frontoclypeal suture deep and wide in middle; distance between lower lobes of eyes 1.8 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.25 × as long as distance between eyes on ventral side; genal length 0.19 × as long as head width immediately below eyes. Antennae largely damaged. Thorax and abdomen . Pronotum 0.94 × as long as width, rounded with a small process at each side; posterior margin 1.22 × as wide as anterior margin; pronotal disc without distinct nodules in middle area; disc and side strongly rugose transversely. Scutellum semicircular, with sparse pubescence. Elytra 5.26 × as long as prothorax and 3.44 × as long as shoulder width; basal 1/3 with coarsely punctures; apex more or less rounded at margin and with a small spine at suture. Apex of terminal sternite rounded or slightly truncate. Male terminalia . Apex of ventral median lobe emarginate and apex of dorsal lobe with rounded; ventral lobe distinctly longer than dorsal lobe; spined region of internal sac divided into two sections; first section with sparse short simple spines on sides near base; second section with fairly dense long simple spines; unspined gap between first and second section above as long as second section ( Fig. 91a ). Eighth sternite rounded at side, shallowly emarginate at apex, with long and fairly long setae arising terminally; ventral surface with sparse cloud-like processes ( Fig. 91b ). Eighth tergite rounded at apex, with fairly dense simple spines and multi- branched spine on surface ( Fig. 91c ). Paramere long, 2.5 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 91d ). Female. Unknown. Distribution Southwestern Western Australia ( Fig. 113 ). Comments This species differ from others species of Uracanthus in having very short genal length; pubescence on the elytra uniform without any line or stripe of denser pubescence. No other specimen matches the type . Material examined Holotype . ♂ . WA: Mullewa ( 28º26'S , 115º35'E ), Miss J. F. May ; bearing a name label on which ‘TYPE’ was written in red; 8 segments of left antenna and 8 segment of right antenna damaged ( SAM ).
