Howeotranes insularis (Pascoe, 1874:387)



Taxonomy & Nomenclature

Synonym/s: Tranes insularis Pascoe, 1874:387 (basionym)


Transferred to the newly erected genus Howeotranes by (Zimmerman, 1994:696).


Conservation Status

Presumed extinct (DECC NSW, 2007:23)

Last record: 1920's (DECC NSW, 2007:23)


The holotype was collected sometime prior to 1875, and the species was already reported as uncommon by (Olliff, 1889:91). The second (and last) specimen was collected in the 1920's (DECC NSW, 2007:23). Only one species of weevil (Isacantha inculta) was collected on the island during a 2017 expedition (Reid et al., 2018), providing further evidence that the species may be extinct (Oberprieler & Zimmerman, 2020:594).



Lord Howe Island, New South Wales, Australia


Olliff (1889:91) states: "Summit of Mount Ledgbird (2,500 feet) ; also found on the low-lying lands". Also inhabited the summit of Mt Gower by (DECC NSW, 2007:23).


Biology & Ecology

"the biology and hosts of Howeotranes are unknown"

(Oberprieler & Caldara, 2012:57)



Only known from two specimens (DECC NSW, 2007:23).
