Current nomenclatural status
The World Spider Catalog lists Orphnaecus dichromatus as a synonym that has been transferred to the genus Chilocosmia (see “see Chilocosmia” entry)【5†L1-L4】. Consequently, the accepted name is Chilocosmia dichromata (Schmidt & von Wirth, 1992).
Common names
- New Guinea Black Fury
- New Guinea Two‑Toned Earth Tiger
Description
Orphnaecus dichromatus is a medium‑large theraphosid tarantula noted for its striking coloration: a dark brown to black dorsal surface with bright orange‑yellow or reddish setae on the legs and abdomen, giving a two‑toned “tiger” appearance. Hobbyist observations describe the species as fast, highly defensive, and agile, characteristics typical of Old World tarantulas.
Distribution and habitat
The species is native to the island of New Guinea, specifically reported from Papua New Guinea and the Indonesian part of the island. It inhabits tropical forest floors, constructing burrows or using natural ground cover.
Behavior and husbandry (captivity)
In the pet trade, O. dichromatus is marketed under the name “New Guinea Black Fury.” It is regarded as suitable only for experienced keepers due to its speed and defensive temperament. Recommended enclosure conditions include a secure lid, substrate suitable for burrowing, and a warm, humid environment that mimics its natural tropical habitat.
Taxonomic notes
The original description was published in 1992 by Schmidt & von Wirth under the genus Orphnaecus. Subsequent taxonomic revisions transferred the species to Chilocosmia based on morphological re‑evaluation, as reflected in the World Spider Catalog entry for the genus Orphnaecus【5†L1-L4】.
