Pseudhystrix

Pseudhystrix is a genus of porcupines found in Southeast Asia. The name comes from the Greek word "pseudes" meaning false and "hystrix" meaning porcupine, referring to its superficial resemblance to true porcupines. There are currently two recognized species within this genus: Pseudhystrix cristata and Pseudhystrix malaccensis.

Pseudhystrix cristata, commonly known as the crested porcupine, is the larger of the two species. It is characterized by its long, stiff quills that can be raised when threatened. These quills are typically black with white bands. The crested porcupine inhabits a range of habitats including forests, scrublands, and rocky areas. They are primarily nocturnal and herbivores, feeding on roots, bark, fruits, and seeds.

Pseudhystrix malaccensis, or the Malayan porcupine, is similar in appearance to P. cristata but is generally smaller and has shorter quills. It is found in the Malay Peninsula and surrounding islands. Like the crested porcupine, it is a nocturnal herbivore and uses its quills for defense.

Both species of Pseudhystrix are solitary animals, coming together only for mating. They are known to dig burrows or utilize existing shelters like hollow logs or caves. Conservation statuses for these species vary, with some populations facing threats from habitat loss and hunting. Further research is ongoing to better understand the ecology and conservation needs of Pseudhystrix.
