Abstract
Two new species of Camillea are described from localities on an east–west transect through Ecuador between the latitudes 1°00’N and 1°00’S. Camillea ovalispora was collected in San Vicente de Huaticocha, an area characterized as humid lowland rainforest and premontane cloud forest; C. unistoma was collected at Cuyabeno, a protected area with black water inundated forest and primary rainforest on terra firme. Further, C. heterostoma var. macrospora is elevated to full species status as C. macrospora. New country records of six Camillea species are annotated from the same east-west transect. These are C. flosculosa, C. fossulata, C. hainesii, C. macrospora, C. scriblita, and C. tinctor. Also, previously recorded species have been annotated with new specimens added. Additionally, six distinct taxa from the transect that appear to be undescribed were included in the analysis; one is partly described but not the others due to insufficient material. The data showed an obvious altitude influence on the distribution and frequency of Camillea species. The diversity of species is lower on the western part of the transect compared to the eastern side, probably due to multiple factors such as differences in search intensity between the two slopes, difference in annual rainfall, and possibly the availability of host plants. Camillea taxa were only found at altitudes below 2,000 m, with the highest diversity below 600 m. Palmae is reported as a new host for Camillea species.
