838247D06AA154B6AF9CD72E998BF627.taxon	distribution	Distribution and natural history. Pristimantis burtoniorum is known only from the type locality in the Machay Reserve, Rio Verde Parish, Banos township, Tungurahua Province, Republic of Ecuador (Fig. 2) at an elevation of 2940 m. This locality is comprised of montane cloud forest (MAE 2012), with a canopy of 15 m with a dense layer of bryophytes and epiphytes and an understorey dominated by bromeliads of 30 - 60 cm in height from the forest floor. This is the predominant microhabitat for Pristimantis burtoniorum; all specimens were found hiding in the base of bromeliads leaves. Sympatric species are Pristimantis festae complex, P. buckleyi complex, Niceforonia sp and Hyloscirtus sp.	en	Reyes-Puig 1,2, Juan Pablo, Reyes-Puig 1,3,4, Carolina, Franco-Mena 5,6, Daniela, Jost 2, Lou, Yanez-Munoz 1,2, Mario H.

Species epithet is the genitive plural of " Burton " in Latin, in recognition of John and Viv Burton, who founded and led the World Land Trust for most of its existence. Their impact on nature conservation is worldwide. Without the World Land Trust's " Forests in the Sky " initiative, it would not have been possible for EcoMinga Foundation to establish the Machay Reserve and complete the Llanganates-Sangay Ecological Corridor.	en	Reyes-Puig 1,2, Juan Pablo, Reyes-Puig 1,3,4, Carolina, Franco-Mena 5,6, Daniela, Jost 2, Lou, Yanez-Munoz 1,2, Mario H.

F67F2ED795095765AFAA95EFB4430C41.taxon	distribution	Distribution and natural history. Pristimantis maryanneae is known only from the type locality, Naturetek Vizcaya Reserve, located at Ulba Parish, Banos township, Tungurahua Province, at 2400 m elevation in the eastern versant on the Andes in central Ecuador (Fig. 2), near the southwest limit of Llanganates National Park. This species was found in mature montane cloud forest (MAE 2012), characterised by a canopy of 25 to 30 m covered by epiphytes, orchids, bromeliads, bryophytes, and ferns. The bambusoid grass genus Chusquea was predominant in the area. The five known specimens of Pristimantis maryanneae were found in the lower stratum of the forest, sitting on leaves from 60 to 160 cm; one individual was found in leaf litter during the day, while all others were found on fern leaves at night.	en	Reyes-Puig 1,2, Juan Pablo, Reyes-Puig 1,3,4, Carolina, Franco-Mena 5,6, Daniela, Jost 2, Lou, Yanez-Munoz 1,2, Mario H.

F67F2ED795095765AFAA95EFB4430C41.taxon	etymology	Etymology. Specific epithet is in recognition of Maryanne Mills (nee Sawle), a zoologist from Perth, Australia. In 1986, she helped her husband, David Mills, set up the UK's premier wildlife tour operator, Naturetrek and she has been based in England ever since. Her passion for the environment and its conservation has led Naturetrek to donate widely to this cause, including donations to World Land Trust which allowed EcoMinga Foundation to purchase more than 1,000 acres of Ecuadorian cloud forest, where this new species of terrestrial frog was discovered.	en	Reyes-Puig 1,2, Juan Pablo, Reyes-Puig 1,3,4, Carolina, Franco-Mena 5,6, Daniela, Jost 2, Lou, Yanez-Munoz 1,2, Mario H.
