In 1991, in eastern Venezuela, Frank Saager found specimens of what he was to call Psalmopoeus irminia. He recorded the locality as “Estado Guyana and the Gran Sabana.” 
Saager refers to land between Venezuela and Guyana as Estado Guyana (hatch marks by Sanger ). Directly south is the Gran Sabana (Great Savanna). The Gran Sabana is an expansive, geologically unusual area in southeast Venezuela. It extends partly into Guyana and northern Brazil.
Throughout the rolling plains that dominate the Gran Sabana are spectacular land features, including sedimentary massifs or tepuis, sprawling cave systems, underground rivers, and sinkholes. All are the result of eons of water acting on calcium carbonate.
One of the localities Saager reports is the 7,671 ft. Roraima Tepui. Presumably he means vicinity as he adds P. irminia is not found above 2,000 ft.
Elsewhere in the Gran Sabana, Saager documents two additional localities (see left):
Within the regional locality of Estado Guyana and the Gran Sabana, Saager says P. irminia is widespread but not common. He reports finding them on trees in areas of contiguous forest, under bark or in holes associated with branches or roots. These forests, says Saager, are becoming rare due to centuries of slash and burn.
The forests receive seasonal rainfall. According to Saager, day/night extremes of 104/59F (40/15C) are not uncommon. He documents mating occurring in the dry season (December to June), with spiderlings emerging in 7-8 weeks (5-6 weeks for first instar), numbering 50-200 (100 typical) .
In habitat detail, Saager’s account is rich compared to most scientific descriptions, with information helpful to keeper and breeder alike. May the above enrich your experience with this species.
