[2] The holotype specimen was collected by George Hudson during the Sub-Antarctic Islands Scientific Expedition and is held at Te Papa.

[2][3] This species was described by Broun as follows: Subopaque, broadly oviform, moderately convex, sparingly clothed with fine short testaceous setae; the surface more or less variegated with dull fuscous and rufo-castaneous; palpi, antennae, and tarsi red, legs infuscate testaceous; ventral segments variegate, fuscous and fusco-testaceous, with somewhat elongated punctures and very scanty pubescence; the metasternum testaceous.

Clypeus distinctly marginated, subtruncate in front, its punctuation rather shallow, moderately coarse, not very close, somewhat rugose; it is quite glossy, and reddish-brown.

Thorax strongly transverse, bisinuate at base, widely incurved in front, the anterior angles not projecting beyond the back of the eyes, posterior angles rectangular but obtuse; its sides gently rounded, very finely margined, and bearing numerous rigid rufescent setae; disc opaque, fuscous, the sides broadly pale rufo-fuscous; punctuation distinct, yet rather fine.

Elytra of exactly the same width as thorax at the base, widest behind the middle, apices individually broadly rounded; their striae well marked alongside the suture, less so beyond; the sculpture of these striae peculiar — not definite punctures, but shallow elongate impressions, each minutely margined; the interstices closely transversely rugose; the sides bear stiff reddish setae, but there are very few on the disc, those that are visible usually arise from the few scattered pale spots.
