Pentarthrum blackburni (Sharp)
Hawai'i Islands: Laysan (?), O'ahu
|local name: -|
extinction date: (?)
|This species was originally
known only from the immediate vicinity of Honolulu on the island of O'ahu,
but was found in the year 1923 in small numbers by D. T. Fullaway on
Laysan, whereto it was obviously accidentally introduced from O'ahu.
It is today considered extinct, the reasons therefore, however, seem to be unknown.
