This literature review aims to synthesise existing knowledge on research on pollination of orchid species in Guatemala. Orchids, known for their diverse and specialised interactions with pollinators, play a key role in the ecosystems of this Central American country. As a base for our research, we have used the orchid checklist published in 2018 where more than 1200 taxa have been listed. Then we conducted a systematic search of academic databases, including, but not limited to PubMed, Web of Science, Scopus and relevant botanical databases. From 1231 orchid species reported to occur in Guatemala and classified in 221 genera, we have found data on pollination of only 98 taxa, classified in 71 genera. Through an exhaustive survey of the relevant scientific literature, this review intends to provide a comprehensive summary of the available data, highlighting gaps in current knowledge and suggesting directions for future research. Research on pollination in tropical orchids presents a formidable challenge due to the immense diversity of species, the intricacies of pollination mechanisms, the elusive nature of pollinators and the susceptibility of these ecosystems to environmental changes. Despite these challenges, the importance of unravelling these mysteries is underscored by the critical role orchids play in tropical ecosystems and their potential implications for conservation and biodiversity.
