Cyriopagopus schmidti (ke bang)

Few tarantulas reframe what the family is capable of quite like Cyriopagopus schmidti. Long known under the synonym Haplopelma schmidti, this powerful fossorial species inhabits the clay-laden slopes of southern China and Vietnam, where mist-shrouded forests hide burrows belonging to one of the largest theraphosids in Asia. Adults wear warm amber to golden-brown tones, with deeper banding across the opisthosoma that catches the light whenever a female pauses at her burrow mouth. Females routinely exceed 8 cm in body length, and they carry that size as a heavy-bodied, deliberate presence — the kind of animal that commands attention without moving at all.

Fast, decisive, and strongly defensive, Cyriopagopus schmidti excavates deep tunnels into clay substrate and guards them with unmistakable intent. This is a species you study rather than handle, from a respectful distance, with the patience that large Old World fossorials reward. What lifts it beyond sheer size and attitude is something genuinely rare in Theraphosidae: documented maternal behaviour. Females have been observed presenting prey to their spiderlings — uncommon enough among tarantulas to shift the entire experience of keeping the animal. You are not simply watching a large spider feed; in the right season, you are watching something that resembles care.

A deep fossorial setup is essential — at least 10 cm of substrate, ideally a compact mixture of coconut fibre and clay or loam that holds burrow structure without collapsing. A starter hide encourages initial settlement, and a water dish should be available at all times. Humidity runs higher than for many Asian species, so regular misting of one side of the enclosure maintains the damp gradient the animal seeks. Temperatures of 24–28°C suit it well, and while cross-ventilation remains important, airflow should not dry the substrate excessively.

This is a species for the experienced keeper who has moved past the usual milestones and is ready for an animal that truly fills the room. The golden colouration, the imposing build, the strike speed that turns feeding into a focused ritual — all of that is already substantial. But it is the maternal behaviour that tends to permanently rearrange a keeper's sense of what tarantulas can do. Cyriopagopus schmidti earns its place in long-term collections not because it is easy, but because, year after year, it keeps offering something worth watching.
