A terrestrial, burrow- and web-associated tarantula from the island of Socotra. Silk can connect the retreat, substrate, and nearby structures into a broad working area.

Meet Belinda
Belinda is the second Monocentropus balfouri currently in my care. Her available portrait is more secretive, showing her partly visible within the retreat.

Natural history.
The blue-and-cream colour pattern is shared at species level, but posture, web placement, feeding, and molt history remain individual. That is why Belinda has her own page.
Belinda's vivarium and Codex record are kept separate from Bella's. The page can grow with better portraits without merging the two animals' histories.
Taxonomy and range
Monocentropus balfouri is an accepted theraphosid endemic to Socotra, Yemen. A recent integrative revision retained the species in Monocentropus and documented its island habitat and burrows while reorganising related Arabian and African taxa.
Burrows, shelter, and activity
Field photographs and collection experience both place the species around silk-lined ground burrows. The web can spread through nearby soil and structure, joining several entrances into a concealed working area that is far larger than the visible spider.
Feeding ecology
Arthropods are taken by ambush at or beyond the retreat. Captive animals can tolerate close neighbours when conditions are carefully managed, but wild social organisation remains insufficiently studied and Belinda's record should not be merged with Bella's.
Defence, senses, and movement
There are no urticating hairs. Concealment, speed, and defensive posturing are more relevant, while the contrasting blue-and-cream colour is most obvious only when the animal leaves cover.
In my care
Meet Belinda.
Belinda has her own profile because a shared species does not mean a shared history. Her vivarium video and Codex record document her as an individual, independently from Bella’s photographs and observations.
