Geodorcus auriculatus
species of beetles

Geodorcus auriculatus is a large flightless stag beetle that is found in the southern part of the Coromandel Peninsula and on Mount Te Aroha in the Kaimai range of New Zealand.
Description
Geodorcus auriculatus are large dull to glossy black or brownish black beetles. Their exoskeleton is covered in dots and minute hairs with four inconspicuous ribs. The length for male specimens ranges from 21 to 29 mm. This length includes their impressive mandibles. Female beetles have much less variation in their size, ranging in length from 19–20 mm. Their smaller mandibles allow them to be distinguished from male beetles. Their head is widest behind the eyes and distinctly depressed and smooth in males, less so in female beetles.
Distribution
Geodorcus auriculatus is found from Manaia on the western side of the Coromandel Peninsula to Mount Te Aroha in the Kaimai range, south of the Coromandel. They can be found from near sea level to 950m on Mount Te Aroha.

Why this record matters
“Geodorcus auriculatus” is worth following because a concise public description often conceals a longer documentary argument. Here, Geodorcus, auriculatus and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 4, 2026. The linked authority identifier is Q2062361. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
