Adoryphorus Blackburn, 1889

Adoryphorus Blackburn, 1889: 1412 . Type species: Dasygnathus coulonii Burmeister, 1847 , by monotypy.

Diagnosis ( Figs. 64–65 ). Body 9–17 mm long, reddish black to black, ovate, low convex, head with at most a low tubercle on vertex, pronotum unarmed. Maxilla and galea reduced to small conical pieces, unarmed, terminated by pencils of sensory setae; mentum longitudinally convex, disc setose, ligula with apex rounded, palps globular and short; mandibles just visible at sides of clypeus, external margin rounded. Antennae with 9 or 10 antennomeres, club with 3 lamellae, shorter than length of shaft. Clypeus glabrous, sides straight, not or only slightly converging towards truncate apex, slightly emarginate; clypeofrontal suture slightly carinate and transverse. Pronotum evenly convex, lightly and finely punctate, anterior edge with narrow membrane not extending to anterior angles, basal ridge obsolete at least in median third, lateral margins unguttered and converging towards apex. Elytra deeply impressed and distinctly punctate, lateral margin unguttered, epipleural plane in anterior half vertical. Female penultimate abdominal ventrite with row of setae close to posterior edge. Protarsomere 5 about as long as tarsomere 1; proclaws of males strongly curved, sometimes slightly asymmetrical; metafemur slender; metatibia of female stout with apex dilated. Parameres with internal margin irregular or distinctly toothed or serrate, usually setose.

Distribution. The genus contains three species ( Weir et al. 2019): A. coulonii (Burmeister, 1847) , A. canei Carne, 1957 ( Figs. 64–65 ) and A. mellori Carne, 1957 , that occur from southern Queensland to southeastern South Australia and northern Tasmania ( Carne 1957, Map 15), with A. coulonii having established in the South Island of New Zealand ( Stufkens & Farrell 1980). Adults of all three species were adequately described and keyed by Carne (1957), and Dechambre (2005) illustrated adults of A. canei and A. coulonii . McQuillan (1985) described the larva of A. coulonii .

Remarks. Carne (1957) named A. canei for “Miss H.M. Cane (Mrs. B. Cameron)” and so should have used an -ae ending ( International Commission on Zoological Nomenclature 1999, Article 31.1.2). Even though it was improperly formed, the original spelling must be preserved in line with Article 31.1.3 as it should not be corrected under Article 32.5.
