Pamphobeteus ultramarinus female • 3″

Description

A slightly smaller member of its genus, Pamphobeteus ultramarinus is from the lower Andes in Ecuador. Elevation and eastern slope give the area a different climate than rainforest below. P. ultramarinus is remarkable for distinctive black and purple in females and immature males. Femurs are purplish and there are metallic markings on the carapace. Color and iridescence are unusual in female and immature male Pamphobeteus, perhaps explaining the draw of this species. Captive specimens are hardy and eat well.

Care of P. ultramarinus juveniles and adults is relatively straightforward. We find they do better on dry substrate with a large-surface-area water dish to boost humidity. Ventilation is restricted only enough to allow humidity to climb 20-30% above typical room air (50% RH). Room temperature (68-72F) is fine, warmer temperatures to 80F and possibly higher are tolerated. Note, these parameters are guidelines and work for us. Don’t worry too much about the numbers. They are simply a way for us to communicate an approach. We do measure, but once we are familiar with a setup, we no longer measure. Keep in mind, others have certainly raised P. ultramarinus differently and successfully.

Care highlights:

• substrate on the dry side for juveniles and adults
• slightly elevated humidity (70-80% RH) + water dish support
• room temperature (68-72F) up to 80F,  possibly higher
• consider a hide, forest litter and plantings for enrichment
