Speleopsocus is a genus of psocids (booklice) in the family Prionoglarididae from the Tepui of Venezuela. [1] It is monotypic, containing only one species, Speleopsocus chimanta. [2]
Andreas Wistuba is a German taxonomist and botanist specialising in the carnivorous plant genera Heliamphora and Nepenthes. More than half of all known Heliamphora species have been described by Wistuba.
Heliamphora chimantensis is a species of marsh pitcher plant endemic to the Chimantá Massif in Venezuela. Specifically, it has been recorded from Apacará and Chimantá Tepuis. It is thought to be more closely related to the southern growing H. tatei and H. neblinae than to any of the other species found in the Gran Sabana and its tepuis. All other species known from this region have between 10 and 15 anthers, while H. tatei, H. neblinae and H. chimantensis have around 20. However, the anthers of H. tatei and the closely related H. neblinae are 7–9 mm long, while those of H. chimantensis only reach 5 mm in length.
Heliamphora heterodoxa is a species of marsh pitcher plant native to Venezuela and adjacent Guyana. It was first discovered in 1944 on the slopes interlinking Ptari-tepui and Sororopan-tepui and formally described in 1951.
Heliamphora hispida is a species of Marsh Pitcher Plant endemic to Cerro Neblina, the southernmost tepui of the Guiana Highlands at the Brazil-Venezuela border.
Heliamphora pulchella is a species of marsh pitcher plant endemic to the Chimanta Massif and surrounding tepuis in Venezuela. It is one of the smallest species and closely related to H. minor.
Trogiomorpha is one of the three major suborders of barklice, booklice, and parasitic lice in the order Psocodea, alongside Troctomorpha and Psocomorpha. There are about 8 families and more than 430 described species in Trogiomorpha. Trogiomorpha is widely agreed to be the earliest diverging of the three suborders, and retains the most primitive characteristics.
Heliamphora exappendiculata is a species of marsh pitcher plant native to the Chimantá and Aprada Massifs of Bolívar state, Venezuela. It was for a long time considered a variety of H. heterodoxa, but has recently been raised to species rank. Pitchers collect insects on flattened pitcher mouths which function as 'landing platforms' upon which prey falls from surrounding vegetation. Also, the pitcher shape effectively collects leaf litter and organic debris which may serve as additional source of nutrition for plants, similarly to H. ionasi.H. exappendiculata hybridizes naturally with H. pulchella and H. huberi in areas within which they grow together. This species occurs in shaded conditions, apparently preferring them over other habitats. In addition, plants upon Chimanta and Amuri Tepui grow directly upon the walls of gorges and ravines where surfaces are permanently wet. In contrast to those populations, on all other tepuis and massif regions the species grows on summit savannahs and stunted or shrubby forests, though these individuals represent a minority in habitat choice.
Anomaloglossus rufulus is a species of frog in the family Aromobatidae. It is endemic to Venezuela where it is known from a few tepuis in the Chimantá Massif in the Bolívar state.
Upuigma-tepui, also known as El Castillo, is a tepui in Bolívar state, Venezuela. A relatively isolated peak, both it and nearby Angasima-tepui lie just south of the vast Chimantá Massif, from which they are separated by the Río Aparurén valley. Upuigma-tepui is situated entirely within the bounds of Canaima National Park.
Chimantaea is a genus of flowering plants in the family Asteraceae.
Prionoglarididae is a family of the order Psocodea that are barklice characterized by the reduction or simplification of the lacinia in adults and the specialised form of the male genitalia. It contains the only known genus of animals, Neotrogla, where females possess a penis-like organ and take on typical male sex roles.
The natural range of the carnivorous plant genus Heliamphora is restricted to the southern Venezuelan states of Amazonas and Bolívar, and to adjacent portions of northern Brazil and western Guyana, an area corresponding to the western part of the Guayana Shield. These plants are largely confined to the summits and foothills of the sandstone table-top mountains of the region, known as tepuis.
Aprada-tepui is a tepui in Bolívar state, Venezuela. It has an elevation of around 2,500 metres (8,200 ft) above sea level. It gives its name to the Aprada Massif, which also includes the smaller Araopán-tepui to the east. A steep, semi-circular ridge connects these two summits. Aprada-tepui lies 22 kilometres (14 mi) northwest of the much larger Chimantá Massif and around 25 km (16 mi) east of the Pemón village of Urimán.
The Chimantá Massif is a highly fragmented complex of tepuis in Bolívar state, Venezuela. The massif comprises around 11 tepuis and has a total summit area of 615 km2 (237 sq mi) and an estimated slope area of 915 km2 (353 sq mi). It is divided in two by the Río Tírica, with the northern section being both larger and higher. The massif is notable for its high species richness and for its varied habitat types. It reaches an elevation of 2,698 metres (8,852 ft) on its highest peak, Murey-tepui. The massif is situated entirely within the bounds of Canaima National Park. It hosts extensive cave systems, including the world's largest known quartzite cave, Cueva Charles Brewer, named after discoverer Charles Brewer-Carías. The processes behind their speleogenesis are the subject of some debate.
Angasima-tepui, also known as Adanta, Adankasima or Adankachimö, is a tepui in Bolívar state, Venezuela. A relatively isolated peak, both it and nearby Upuigma-tepui lie just south of the vast Chimantá Massif, from which they are separated by the Río Aparurén valley. Amurí-tepui, the closest member of the Chimantá Massif, is only 8 kilometres (5.0 mi) from Angasima-tepui.
Charles Brewer-Carías is a Venezuelan explorer and naturalist. Known as the "Humboldt of the twentieth century", Brewer-Carías has led more than 200 expeditions to remote parts of the Venezuelan Guayana, particularly the tepuis of the region. His discoveries include the sink holes of Cerro Sarisariñama and the world's largest known quartzite cave, Cueva Charles Brewer.
Neotrogla is a genus of barklice noted for its reversed sex roles and organs, traits shared by all species of the genus.
Afrotrogla is an African genus of large-winged psocids in the family Prionoglarididae, discovered and described by Charles Lienhard. There are three described species in Afrotrogla, all found in certain caves of Namibia.
Sensitibilla is an African genus of large-winged psocids in the family Prionoglarididae, discovered and described by Charles Lienhard. It contains four species.
Siamoglaris is a genus of psocids in the family Prionoglarididae, the only one in the Indomalayan realm.
