Carneoryctes Özdikmen, 2009: 139 (replacement name). Type species. Pseudoryctes tectus Blackburn, 1892 , by original designation. Redescription. Male (from Carne 1957 ; Endrődi 1985 ; and P.M.H. specimens) ( Figs. 3–13 ). Body reddish brown, bicolorous, or black, 12–27 mm long. Mentum strongly compressed and reflexed at ligula; maxillary palp slender, apical palpomere truncate; galea reduced to small, untoothed pieces; labrum usually visible; mandibles visible. Antenna with 10 antennomeres, club longer than shaft. Clypeus at angle to plane of frons, nearly always verti- cal, concave and with truncate anterior face glabrous or setose, disc rarely setose. Clypeofrontal ridge transverse, strongly elevated. Frons frequently setose; ocular canthi large, rounded or subangulate, densely setose. Pronotum with anterior margin corneous and bearing median elevated process or horn, latter tapering to a simple, bifid, trifid, or branched apex; anterolateral angles acute or obtuse; lateral ridges sometimes contracted or interrupted just before basolateral angles, their margins frequently with dorsal setae; basal ridge sometimes continuous; disc often setose, transversely rugulose with deep excavation limited by elevated angles or lateral horns, latter usually simple, disc rarely depressed below level of basal margin. Each elytron with sutural stria linear or linear-punctate, disc with welldefined striae, punctures simple or weakly umbilicate, surface sometimes microreticulate, epipleuron with short lateral setae continuous to apices. Pygidium setose across base, apical ridge glabrous or setose. Postcoxal prosternal process short, setose, often not visible. Abdominal sternites setose across posterior margins. Protibiae tridentate with spur inserted anterior to base of medial denticle; protarsomere 5 usually longer than protarsomere 1, not thick- ened; prothoracic claws simple, slender; metathoracic legs slender or moderately short; metatibiae bicarinate, distal ciliae short, sharp, closely set, spurs unequal, curved; metatarsi elongate, tarsomeres 1 and 5 subequal in length. Parameres symmetrical, external margin broadening pre-apically, in lateral view face arcuate, ratio of phallobase length to paramere length 1.5–2.5:1. Included species. General geographic ranges (all in Australia ) were taken from Carne (1957 , 1981 ), Allsopp & Lloyd (1987) , and Howden & Malý (2005) .
