Nepenthes pitopangii is a tropical pitcher plant endemic to the Indonesian island of Sulawesi. Discovered in 2006, N. pitopangii was initially known from a single plant at a remote locality in Lore Lindu National Park. Efforts made in the following years to locate further populations on surrounding mountains proved unsuccessful. In March 2011, a new population of N. pitopangii consisting of around a dozen plants was discovered more than 100 km from the type locality. Nepenthes pitopangii appears to be closely related to N. glabrata, from which it differs most obviously in its upper pitcher

Nepenthes monticola is a tropical pitcher plant known from a number of mountains in the west central highlands of western New Guinea, where it grows at elevations of 1,400–2,620 m above sea level. Prior to its description as a species in 2011, N. monticola was lumped with the closely related N. lamii.

Nepenthes diabolica is a tropical pitcher plant known only from a single mountain in Central Sulawesi, where it occurs at c. 2,200–2,300 m above sea level. It is characterised by an exceptionally developed peristome and conspicuous, woolly pitcher indumentum. Morphologically it is closest to N. hamata, the only other species from Sulawesi with a similarly elaborated peristome. The species was known to botanists as early as 2005, when Ch'ien Lee announced the discovery of a new form of N. hamata with an exceptionally dense indumentum. For years afterwards the taxon was informally known in
