Xenesthis intermedia • 1 1/4″

Xenesthis intermedia (Venezuelan blue bloom), captive bred. A large, dark terrestrial, native to the northern Andes in northwest Venezuela. The metallic starburst pattern on the carapace is distinctive in the genus.


Xenesthis intermedia, described in 1945, is a large, elegant, mostly black terrestrial from the northernmost extent of the Andes in northwest Venezuela (Trujillo Department). The collector, Dr. Quintini, reported finding the specimen at 1500 m (4921 ft). Interestingly, the species description reports locals fear X. intermedia for its bite. [1]

In captivity, X. intermedia is not difficult to raise as long as a few key requirements are met. Of these, water balance is the most important. Even with heavy feeding, specimens do better in more humid environments, higher than average US room humidity for instance. Saturation is not necessary however. There are many ways to boost humidity. The best methods avoid uniform dampening of substrate, which encourages microbial, fungal, and parasitic growth.

As for temperature, room temperature, 20–22 °C (68–72 °F), is ideal. Summertime highs and winter lows a few degrees beyond this range are tolerated.
