03C187C0FF9BFF88FF51D9D4FEB3F784.taxon	diagnosis	Diagnosis. Metapocyrtus nacolod sp. nov. is related to Metapocyrtus lindabonus Schultze 1922, Metapocyrtus kuehli Cabras, Villanueva & Medina, 2021, and Metapocyrus dagtum Cabras, Torrejos & Medina, 2021, all from Mindanao Island but can easily be distinguished for having a broad subtriangular scaly patch of iridescent turquoise adpressed round scales with a golden-yellow sheen on each side of discs, and three broad transverse bands of similar scales in the elytra. Additionally, Metapocyrtus nacolod has a stouter median lobe and median lobe’s apodeme that is almost 5 x longer compared to the median lobe of the previously mentioned species. The new species is similar to Metapocyrus dagtum for the shape of its pronotum but is similar to Metapocyrtus lindabonus, and Metapocyrtus kuehli for its elytral profile and scaly markings. Due to the chaotic subgeneric classification of Metapocyrtus, we refrain from assigning this species to a particular subgenus.	en	Cabras, Analyn A., Senarillos, Tristan Luap P., Ibañez, Jayson C.

03C187C0FF9EFF83FF51DCB4FAC0F858.taxon	diagnosis	Diagnosis. Metapocyrtus silago sp. nov. is related to Metapocyrtus (Trachycyrtus) perarmatus Schultze, 1934 from Panaon Island, Leyte, M. (T.) spinipennis Schultze 1925 from Biliran Island, M. (T.) macrospinosus Schultze 1925 from Camarines Norte, Luzon Island, M. (T.) acutispinosus Schultze 1925 from Samar Island, and M. (T.) crassispinosus Schultze 1925 from Surigao, Mindanao, but can easily be distinguished among its congeners for the reddish-brown integuments of its pronotum and elytra compared to the black integuments of its congeners, and the scaly metallic blue transverse bands at the base and apex of the elytra compared to the random sparse scales of M. (T.) macrospinosus Schultze 1925, and M. (T.) perarmatus Schultze, 1934, and the three transverse bands of M. (T.) spinipennis, M. (T.) acutispinosus and and M. (T.) crassispinosus. It differs from M. (T.) spinipennis for the swollen base of apical declivity in females with pubescence which is also present in M. (T.) perarmatus. However, the new species is different from the latter for the following features: smaller size, pronotum with indistinct pubescence appearing almost glabrous, elytra wider than pronotum with tapered apex, and elytra with two transverse scaly bands of metallic blue. Metapocyrtus (T.) perarmatus has smaller and randomly scattered scales on pronotum and elytra. All three species: Metapocyrtus silago sp. nov., M. (T.) perarmatus, and M. (T.) spinipennis are found in Leyte with M. (T.) spinipennis locality in the northern part, M. silago southern and M. (T.) perarmatus southernmost. To easily distinguish the three, M. silago has reddish brown pronotum and elytra with two transverse scaly bands at base and apex; M. (T.) spinipennis is black with scattered scales on pronotum and three transverse bands on elytra whereas M. (T.) perarmatus has black pronotum and elytra with minute pale blue scales scattered randomly (Fig. 3). Similar to the reason mentioned above, we refrain from assigning subgeneric placement.	en	Cabras, Analyn A., Senarillos, Tristan Luap P., Ibañez, Jayson C.

03C187C0FF9EFF83FF51DCB4FAC0F858.taxon	distribution	Distribution. Metapocyrtus silago sp. nov. is known so far from Mt. Nacolod, Southern Leyte, Philippines. Brief Ecological Note Metapocyrtus nacolod sp. nov. was collected in Mt. Nacolod, Barangay Catmon, Municipality of Silago, Southern Leyte at 720 – 726 meters above sea level (masl). The collection site is an old logging road, and the area is characterized as a transition between the upper dipterocarp and montane forests (Fig. 5 A – B). Based on preliminary observations, Metapocyrtus nacolod sp. nov. individuals prefer cool and shaded areas. All M. nacolod specimens were found and collected only within the understory vegetation (Fig. 5 E – F). Dominant plants were primarily of the genera Alpinia and Calamus, with various species of tree ferns, ground ferns, tree wildings, and other weeds. The collection site was appropriately 75 m away from the nearest stream. No individuals were found in areas below 700 masl. Metapocyrtus silago sp. nov. was found only within the understory vegetation of the interior forest surrounding Barangay Catmon (Fig. 5 C – D). The collection site is a lowland dipterocarp forest around 232 — 361 masl, dominated by towering premium tree species such as Red Lauan (Shorea negrosensis Foxw.). This species appears restricted only at the lower slopes of Mt. Nacolod, compared to M. nacolod sp. nov. which is found at the middle to high-elevation forests of the same mountain. Conservation Implications The discovery of these two previously undescribed species underscores the need for more natural history studies in the Philippine archipelago. In this critical era of biodiversity crisis, basic taxonomic expeditions can help prevent silent species extinctions. Once “ new species ” are given their proper scientific names, this becomes a springboard for studying their habits and defining their geographical distribution thereby augmenting our understanding of species history and potentially influencing their future conservation efforts. As one of the world’s megadiverse countries, many more unique organisms await discovery in the Philippines. The discovery of M. nacolod sp. nov. and M. silago sp. nov. serves as compelling evidence of the critical ecological significance of the Mt. Nacolod Mountain range. These two new species, combined with pre-existing data on unique flora and fauna from Mt. Nacolod, highlight its remarkable ecological and evolutionary role as a center of species endemism. Consequently, it deserves a national Protected Area (PA) designation. As the last remaining large block of forest in Southern Leyte, the area’s management as a PA spares this precious KBA, and all its biological inhabitants from anthropogenic threats and destruction.	en	Cabras, Analyn A., Senarillos, Tristan Luap P., Ibañez, Jayson C.
