Ariadna taprobanica is a species of spider in the family Segestriidae, commonly known as tube‑dwelling or segestrid spiders. The species belongs to the genus Ariadna, which comprises a worldwide group of mygalomorph‑like araneomorph spiders that construct tubular retreats in soil, leaf litter, or under stones.
Taxonomy
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Arachnida
- Order: Araneae
- Family: Segestriidae
- Genus: Ariadna C. L. Koch, 1841
- Species: Ariadna taprobanica (author, year of description)
The specific epithet taprobanica derives from “Taprobane,” the ancient Greek and Roman name for the island of Sri Lanka, indicating the species’ geographic origin.
Distribution
The species is known from Sri Lanka. Published records and entries in global arachnological databases, such as the World Spider Catalog, list it as endemic or native to that island. No confirmed records of the species occur outside Sri Lanka.
Morphology and biology
Detailed morphological descriptions are limited in widely accessible literature. As with other members of the genus, A. taprobanica is presumed to possess the characteristic elongated chelicerae and six‑eye arrangement typical of segestrid spiders, as well as a habit of building silken tubular retreats. Specific diagnostic characters that separate it from congeners are documented in the original species description and subsequent taxonomic revisions, but these details are not broadly reproduced in general encyclopedic sources.
Conservation status
There is no assessment of Ariadna taprobanica on the International Union for Conservation of Nature (IUCN) Red List. Consequently, its conservation status remains unclassified, and the lack of recent field studies means that population trends are uncertain.
