Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA ARTHROPODA ARACHNIDA ARANEAE THERAPHOSIDAE

Scientific Name: Poecilotheria regalis
Species Authority: Pocock, 1899
Common Name/s:
English Indian Ornamental, King Parachute Spider, Regal Parachute Spider
Synonym/s:
Ornithoctonus gadgili Tikader, 1977
Taxonomic Notes: Populations occurring in Eastern Ghats and Western Ghats could be two different species but this needs taxonomic confirmation.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor/s: Molur, S., Daniel, B.A. & Siliwal, M.
Reviewer/s: Spector, S. & Mason, T. (Terrestrial Invertebrates Red List Authority)
Justification:
The species is widely distributed in India, throughout northern Western Ghats and a few places in the Eastern Ghats. The range and area of occupancy is vast, and although the threats to the habitat and population are noticeable, the species does not come close to being threatened, hence it is classified as Least Concern.

Geographic Range [top]

Range Description: This species is found widely distributed from Dahanee in the north (Western Ghats) and Cochin in the south at an altitude of less than 1,000 m. The extent of occurrence encompassing known and inferred distribution is more than 50,000 km², while the area of occupancy is also likely to be more than 2,000 km². In Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra and Kerala.

Population [top]

Population: Population information is not available. This species is the most common of all Poecilotheria species and is encountered frequently in different habitats. Its population is healthy in natural vegetation; some individuals have been observed in teak plantations and in some degraded areas. However, the individuals seen in degraded habitats are usually males that are migrating in search of females, hence this cannot be taken as a compatible habitat for this species. The populations are severely fragmented although the species has been found in more than 20 locations.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: There is some information on breeding biology from captivity. Males mature between 12 and 18 months and die after the first breeding season or within 24 months (S. Molur, B.A. Daniel & M. Siliwal pers. obs.). Gabriel (2005) reports male maturity after 354 days and survival for up to 344 days after maturity. The Western Ghats males mature faster (12 months) than the Eastern Ghats males (about 18 months) in captivity (S. Molur, B.A. Daniel & M. Siliwal pers. obs.). However, in the wild the maturity time would probably prolong due to environmental conditions and prey availability. Females mature between 5-7 years and live up to 10-12 years and produce on an average two clutches per year of 35-70 hatchlings per clutch in the wild.
Systems: Terrestrial

Threats [top]

Major Threat(s): Habitat loss and degradation are major threats, and collections for pet trade and persecution are additional threats to the species.

Conservation Actions [top]

Conservation Actions: It is reported from Nagarjuna-Srisailam Tiger Reserve and Mudumalai Wildlife Sanctuary.
