Ctenognathus novaezelandiae is a species of ground beetle endemic to New Zealand. Ctenognathus novaezelandiae was first described under the name Anchomenus novae-zelandiae by Léon Fairmaire in a paper presented to the Société Entomologique on the meeting of 18 January 1843 and subsequently published in their Annales. Despite titling his description of the species Anchomenus novae-zelandiae, Fairmaire noted that the species seemed to deserve to be separated from Anchomenus and classified into its own genus, which he declared he would name Ctenognathus (from Greek κτείς, "comb" and γνάθος, "jaw") after its "comb-shaped" mandibles. Fairmaire's description included an account of the beetle's physical characteristics; of its distribution, he wrote only that it came from New Zealand. He also included illustrations for the back of the journal: a colour plate of the whole beetle as well as line drawings of the structure of the legs and mouth. The plate was captioned "Anchomenus (Ctenognathus) Novæ Zelandiae". Fairmaire's holotype specimen could not be found in the MNHN's Fairmaire collection for a 2021 paper, but according to said paper... Wikipedia →

Rare
Under 5% of wildlife watchers report a Ctenognathus novaezelandiae sighting in Auckland on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 618th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Ctenognathus novaezelandiae in Auckland on a given day, against under 5% in August to June, the lowest months.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Ctenognathus novaezelandiae sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ctenognathus novaezelandiae is recorded against all the insects logged in Auckland (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
