Javan Treeshrew

Tupaia hypochrysa

French: Toupaye a gorge dorée / German: Java-Spitzhornchen / Spanish: Tupaya de Java

Other common names: Large Javan Treeshrew

Taxonomy. Tupaia ferruginea hypochrysa Thomas, 1895,

“Sipora [= Sipura Island], Mentawei Islands,” West Sumatra, Indo- nesia .

Based on the recent morphological analyses by E. J. Sargis and others in 2013, this species was elevated from a subspecies of 1. glis to a distinct species. Monotypic.

Distribution. Endemic to WJava.

Descriptive notes. Head-body c.145 mm, tail c.145 mm, ear ¢.6 mm, hindfoot

¢.35 mm. No specific data are available for body weight. The Javan Treeshrew is relatively large and has a long tail. Dorsum is brown-agouti, and underparts are tan-orange. Skull is large, broad, and not elongated like the Large Treeshrew (7. tana) or the Minadanao Treeshrew (71. everetti).

Habitat. Remaining primary forests, with some records from secondary forests, plantations, and fruit orchards, at elevations above 2000 m (more assessment needed to understand elevational range).

Food and Feeding. No information but based on formerclassification under the Common Treeshrew (7. glis), the Javan Treeshrew likely forages on invertebrates and fruit.

Breeding. No information.

Activity patterns. No information, but Javan Treeshrews are presumably diurnal and terrestrial.

Movements, Home range and Social organization. No information.

Status and Conservation. CITES Appendix II. Classified as Data Deficient on The IUCN Red List. The Javan Treeshrew was recently elevated from subspecific status, and new research is needed to fully understand its conservation status. Its distributional area is limited, and Java has undergone a large amount of land-use change over the past 100 years. Java is home to over 141 million people (nearly 57% of the population of Indonesia) and is the most populousisland in the world, with a density of more than 1000 people/km?.
