South American curtain-web spiders from the Guianas, and the family's showpieces: several wear vivid red and blue over the standard funnel-web body plan, which no other diplurid bothers to do.
The keeping is the family program: anchor points for the layered sheet, a funnel retreat, moderate humidity, prey to the silk, and speed at the strike that rewards watching. The bite is unpleasant without medical weight; the color is the reason this genus has a following the rest of the family lacks.
Guianan supply is rare and irregular, captive breeding is thin, and listings are single events priced on the color. Within the curtain-web shelf this is the collector's genus, the one that photographs, and availability rather than price decides who gets one.
The line on each tile: lowest ask per day.
Rarity BETA Rarity is supply, and only supply: the tier is how many sellers have ever carried a species, and for a single seller, how many separate listings. Price is not part of it, and neither is how recently it appeared. Tiers are given to tarantula species only.
