North American funnel-web mygalomorphs: Texas and borderland spiders that drape crevices and cork with layered sheet web and wait at the funnel, delivering the curtain-web experience from a native fauna.
The keeping is the family standard: anchor points, moderate humidity, deep enough substrate to root the retreat, and prey delivered to the silk. Fast at the strike, sedentary otherwise, unremarkable in venom, and covered by the mygalomorph no-handling default on principle.
Collection is thin, local, and seasonal, dominated as always by wandering males with months remaining, while the long-lived web-holding females rarely reach the trade. The genus sells the sheet-web display at native prices, and the standing purchase question of the burrowing spiders applies: which sex, and therefore how many years, is actually on offer.
