Oreophrynella dendronastes is only known from the type locality and immediate vicinities: northeast slope of Mount Ayanganna (5 24.11' N, 59 57.41' W, 1490–1550 masl) District 7, Guyana (Lathrop and MacCulloch, 2007).
Habitat and Ecology
Individuals of this species can be found on broad-leaf vegetation at a height of 1.5 m or more between 2000–2400 h. Their discovery coincided with very humid evenings in which it had either rained all day, or was in the early stages of
a downpour. Oreophrynella dendronastes appeared to be relatively active at night. Individuals have been found on their own, and no breeding groups have been observed. Seven of the eight females of the type series have 20 or more small ova (<0.5 mm) in one ovary; in five specimens the ova are in the left ovary, while in two specimens the ova are in the right ovary (Lathrop and MacCulloch, 2007).
No population status information is currently available for this species.
No major threats are known for this species.
No conservation measures are known for this species.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.
Oreophrynella dendronastes can be distinguished from other species of the genus by a combination of morphological features and colour patterns (Lathrop and MacCulloch, 2007).
