The
genus Hemigalus was named and first described in 1837 by
Claude Jourdan who had a skin and
skeleton of one
zoological specimen at his disposal. In the same year,
John Edward Gray described a specimen from the
Malay Peninsula under the names
Paradoxurus derbyanus and
Paradoxurus derbianus. In 1939,
Reginald Innes Pocock subordinated banded palm civet specimens described between 1837 and 1915 under the genus
Hemigalus and recognised that it is a
monotypic taxon. The genus name is derived from the Greek
hemi (half) and
galus (weasel), due to its appearance.
Subspecies There are four subspecies:
H. derbyanus derbyanus, H. d. boiei, H. d. minor, and
H. d. sipora.
H. d. derbyanus is known from Myanmar and mainland Malaysia as well as Sumatra;
H. d. boiei is known only from Borneo;
H. d. minor, from
South Pagai and the
Mentawai islands; and
H. d. sipora, from
Sipora and the Mentawai islands. There is also a population on
Siberut island, but it has not been attributed to any subspecies. It is estimated that
H. d. minor and
H. d. derbyanus diverged from each other some 2.7 million years ago. == Description ==
