Slender Funnel-web (Bymainiella terraereginae)
The Slender Funnel-web (Bymainiella terraereginae) is a smaller, less robust member of the Australian funnel-web group, known for its elongated body and delicate build. Unlike the more infamous funnel-webs, this species is relatively obscure and occupies forested habitats where it constructs subtle silk retreats.
Scientific Classification
Genus: Bymainiella
Family: Hexathelidae
Common name: Slender Funnel-web
Appearance
- Small to medium-sized funnel-web spider
- Slender, elongated body compared to larger funnel-web species
- Colouration ranges from light brown to dark brown
- Glossy carapace with a softer, less bulky appearance
- Long legs adapted for navigating leaf litter and silk tunnels
Its overall build is noticeably more delicate than that of typical robust funnel-web spiders.
Habitat & Distribution
Bymainiella terraereginae is found in eastern Australia, particularly in:
- Queensland
- Northern New South Wales
It inhabits moist, sheltered environments such as:
- Forest floors
- Leaf litter
- Under logs and rocks
They construct silk-lined burrows or retreats, often with a faint funnel-like entrance.
Behaviour
Primarily nocturnal, this species spends most of its time within its silk retreat.
Diet includes:
- Small insects
- Other invertebrates
They rely on vibrations transmitted through silk to detect prey, quickly emerging to capture it.
When disturbed, they retreat rapidly into their burrow rather than displaying overt aggression.
Invertebrate Keeping
The Slender Funnel-web is not commonly kept but may appeal to specialised keepers interested in Australian mygalomorphs. They require:
- A secure enclosure with deep, moist substrate
- Stable humidity and good ventilation
- Hides and structure to support burrow construction
- Small live prey such as crickets or roaches
As with all funnel-web relatives, caution is advised, and handling should be avoided.
With appropriate conditions, Bymainiella terraereginae can establish a hidden but fascinating burrow system, offering insight into the diversity of Australia’s lesser-known funnel-web species.
