Metapocyrtus (Metapocyrtus) ged Cabras & Medina, 2021 is a Mindanao-endemic species known only in Davao del Sur. Here, we recorded the species first in Bukidnon and the Cotabato region. Moreover, we also provide ecological notes of the species specifically the identities of its food plants, description of its habitat, and potential threats.

Weevils are small beetles with long, narrow snouts which is a characteristic of insects belonging to the Curculionidae family. A study on the species composition of weevils was conducted in the northern part of Mt. Malindang Range Natural Park last February 2023. Field investigations were done using a combination of transect walk and opportunistic sampling. A total of 195 individuals of weevils were recorded, comprising seventeen (17) species belonging to two (2) genera- Metapocyrtus and Alcidodes . Metapocyrtus malindangensis was observed in all sampling sites. Site 1 (Gandawan) had the highest species richness (N=13), and the highest species diversity (H’=2.016) was recorded in Site 2 (Lake Duminagat). Cluster analysis showed that weevil species in Lake Duminagat and Uluhan sa Dapitan have closer similarities. The study also recorded unidentified specimens that are potentially new to science. It is highly recommended that more explorations should be conducted to record the species occurrence of weevils in other parts of Mt. Malindang.
