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.

No. 1, February 2023 Patano et al.: Distribution andEcology of Metapocyrtus (Metapocyrtus) ged Cabras & Medina, 2021 plants are dominated by ferns, lycophytes, aroids, orchids, gesneriads, palms, pandans, Medinilla spp., and gingers. The forest is over the clay to loam soil mostly covered with gravel having an average composition (50%) of very common grasses, sedges, herbs, and ferns; bryophyte density (40%); leaf litter (3 inches); an abundance of Nepenthes (20%); fallen logs (80%); and exposed rocks (80%) ( Figure 3B). Common threats in the area are agricultural activities extending to forested areas, illegal logging, the presence of invasive species (Piper aduncum), and poaching. ...

The forest is over loamy soil mostly covered with gravel having a lesser composition (25%) of very common grasses and ferns, bryophyte density (70%); leaf litter (2 in); an abundance of Nepenthes (10%); fallen logs (70%); and exposed rocks (70%) ( Figure 3A). Common threats in the area are also the rampant agricultural activities that have now extended into the protected zones of Mount Apo ( Figure 4B). ...

Threats in the area include the destruction of forests for road construction and agricultural activities usually by crop plants such as Musa textilis Née (abaca), Zea mays L., and kamote (Ipomoea spp.) ( Figures 4C and D). ...

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.
