The Pseudohapalopus genus comprises only 5 described species, distributed in Bolivia, Ecuador, Colombia, and Trinidad. Curiously, none are firmly established hobby species. By contrast, several recently introduced undescribed species, mostly from Colombia, have gained widespread popularity. The best known is Pseudohapalopus sp, “blue” from Colombia, whose popularity derives mainly from a bright, blue abdomen. More recently, from Boyaca Department, north of Bogatá, comes a similar species most commonly referred to as Pseudohapalopus sp. “Colombia.” It bears an odd combination of blue legs, blue rump posteriorly/yellow anteriorly, and a yellow carapace.
Keeping requirements are unremarkable, those used for Cyriocosmus or Cyclosternum are sufficient. Like its P. sp. “blue” cousin, P. sp. “Colombia” is hardy and has a moderate growth rate. Females achieve sexual maturity at 3-4 inches in 2-3 years. The spiderlings here are feeding on D. melanogaster.
