... distinct and huge humps on dorsum, b) base of rostrum deeply concave dorsally then abruptly raised then gradually declined towards the apex, c) wider pronotum, and d) wider elytra. HABITAT. Specimens of the new species were collected in two populations, first at a forest patch near a banana plantation in Maragusan, Davao de Oro at around 800 m (Fig. 5B) and second within the riparian ecosystem of Kapuka Falls at around 800-900 m in Barangay Lamiawan, Municipality of Caraga, Davao Oriental Philippines. The ecosystems are dominated by several species of Dipterocarpaceae such as Shorea sp. (Fig. 5A). The soil type of both habitats is predominantly karst covered with a thin layer of loam ...

The ecosystems are dominated by several species of Dipterocarpaceae such as Shorea sp. (Fig. 5A). The soil type of both habitats is predominantly karst covered with a thin layer of loam soil from organic decomposition. The species inhabits a tourism destination in Caraga, Davao Oriental, frequently visited by domestic and foreign tourists. A proper environmental management plan must be in place to protect and conserve the species. ...

... Moreover, Coleopterology is an understudied field, with many species remaining unknown to science. Workers hypothesize that many species have undergone silent extinction -lost to science even before being properly named and documented (Löbl et al., 2023;Cabras et al., 2023;. Baltazar (2001) emphasized the dwindling number of expert workers in insect taxonomy and systematics. ...
This communication discusses the perennial gender disparity in science, focusing on the underrepresentation of women in research and leadership roles, particularly in specialized fields like Coleopterology. Significant barriers continue to hinder women's participation in scientific fields. The case of Dr. Analyn Anzano Cabras, a noted Filipino weevil specialist, exemplifies the need to celebrate iconic women scientists to inspire future generations and promote gender equality in academia. This paper also presents Dr. Cabras as an iconic woman scientist and a celebrated Coleopterist whose contributions to science led to the discovery of approximately a hundred beetle species. She has also mentored many budding scholars, making her legacy an indelible mark in Philippine biodiversity research and conservation. This study advocates for increased visibility, mentorship, and support for women in science, aligning with the United Nations Sustainable Development Goals on gender equality (SDG 5).
Beetles play significant ecological roles, including as floral pollinators. In the Philippines, many Coleoptera species have been introduced as new to science over the recent years. However, their ecological roles are often understudied, leading to an incomplete understanding of beetle diversity and forest ecology. In this paper, a possible pollination activity of a scarab beetle Phaeochrous sp. on a corpse flower Amorphophallus sp. was documented in Caraga, Davao Oriental, the Philippines. This provides a preliminary record of the ecological role of beetles in Philippine terrestrial ecosystems and records the first distribution data of both species in the area. We also characterized the Phaeochrous sp. on Amorphophallus sp. to serve as a reference for future taxonomic works. There is a need to conduct further research to provide more evidence of the role of Phaeochrous sp. as a pollinator of Amorphophallus sp. and to
confirm the species-level identity of both subjects. Conservation policies and strategies also need to be strengthened as the study site is a well-visited tourist destination, thus the potential for increased human disturbance.
Three new species of Metapocyrtus: Metapocyrtus inangsabong Cabras, Obrial & Agbas sp. nov., Metapocyrtus lumad Cabras, Obrial & Agbas sp. nov., and Metapocyrtus (Trachycyrtus) uphagpula Cabras, Obrial & Agbas sp. nov. are described and illustrated. Short ecological notes on the species’ habitat, mimicry with other weevils and beetles, and the association between Nepenthes candalaga and Pachyrhynchini in the Philippines are also presented.
