N = 3 for all measurements. 119 Rukmane-Bārbale A., Acal D. A., Mohagan A. B. Integument black. Antennae and legs brownish except black apices. Body surface, rostrum, head, legs, and underside moderately lustrous. Head. Dorsal surface irregularly punctured with few sparse setae; lateroventral side with sparse setae; forehead between eyes flat, with distinct medial groove from sub- apical part to frons; with single, round, metallic scales; eyes medium- size, flat, not prominent in lateral outline of head. Rostrum. (Fig. 5 H) Dorsal surface rugose, with coarse puncture in all length, with minute appressed setae at basal half; slightly longer than wide (LR / WR 1.08); with deep basal groove reaching lateral margin; dorso- lateral edges rounded; dorsum with a distinct, moderate medial groove in all length; dorsal contour straight; lateral sides with subtruncate margin, gradually widened from sub- basal part 120 towards apex; in lateral contour raised dorsally; square- shape impression on each lateral side before the eye. Antennae. Antennal scape longer than funicle, scape reaching after posterior margin of eye, with rare setae along outer margin; antennomeres sparsely covered with setae; club two times longer than wide, covered with brownish setae; funicular segment I slightly longer than II, three times longer as wide, funicular segment II three times longer as wide, segments III- VII as long as wide, slightly increasing in size towards club. Prothorax. Cylindrical, strongly rugose, with fine setae in all length; single, sparsely dispersed round scales of metallic green to blue colour in all length; wider than long (WP / LP 1.21); widest along apical middle, weakly convex on dorsal surface; disc with indistinct medial groove. Elytra. Ovate, longer than wide (LE / WE 1.29), wider than prothorax (WE / WP 1.38), strongly rugose, sparsely pubescent; a tuft of hairs on the sutural beginning of posterior declivity and longer setae along apex (Fig. 7 F); marked with single, sparsely dispersed round scales of metallic green to blue colour; in dorsal contour weakly convex, widest after the middle; lateral contour weakly convex from basal margin towards after the middle then sharply abrupt towards apex. Legs. Legs with moderately clavate femora, without scally markings. Femora with white setae at apical half; tibiae covered with white setae in all length; coxa glossy black, without scales and pubescence. Underside strongly shiny, black, without scally markings; ventrites smooth except slightly wrinkled ventrite I, with short setae in all length (Fig. 7 E). Male genitalia as shown in Fig. 7 A. Female. (Fig. 1 I) Measurements: LB: 8.3; LE: 5.9; WE: 4.1; LP: 2.2; WP: 2.8; LR: 1.3; WR: 1.2. N = 1 for all measurements. Bigger, elytra wider (LE / WE 1.43), with strongly expressed apex; rostrum covered with setae in all length; tuft of hairs on elytra denser compared to male (Fig. 7 G). Otherwise, essentially as in males. Female genitalia as shown in Fig. B – D. Ecological notes: H. cabrasae sp. nov. was collected using a beating sheet on shrubs along a trail at 559 m a. s. l. (Fig. 8). The habitat is characterized by remnants of primary lowland forest, but is predominantly disturbed secondary growth dominated by fig (Ficus) species. The canopy is fragmented, with dense undergrowth consisting of saplings, shrubs, and coarse grasses. Adjacent areas are characterized by farm lots and abandoned agricultural fields, indicating significant anthropogenic pressure (Jakosalem et al., 2005). Deforestation for agriculture and timber harvesting for household use poses a critical threat to the habitat. Given the limited extent of forest cover on Siquijor, the removal of even a single tree has disproportionate ecological impacts. Continued logging and encroachment intensify habitat degradation, emphasizing the urgent need for forest rehabilitation. Restoration efforts are essential not only for conserving biodiversity but also for maintaining these forests as critical watershed areas for the island’s inhabitants. Differential analyses: The new species was compared with five type specimens of H. harpago Heller, 1912 from Luzon Island (MTD) (Fig. 3 A, D) and corresponding specimen from Bohol Island (DUBC) (Fig. 1 D). Both species share the characteristically marking pattern of evenly dispersed metallic green to golden scales on body. The new species, beside geographical isolation, can be distinguished by following features: 1) in lateral view, elytra of H. cabrasae sp. nov. convex and less abruptly angled, whereas in H. harpago Heller, 1912, the elytra is flat with sharp abruption angle of 120 ° (Fig 2 B, E); 2) dorsal groove of rostrum is distinct in H. cabrasae sp. nov. but indistinct in H. harpago Heller, 1912 (Fig. 5 B); 3) differences in shape of male genitalia (Fig. 6 C- D).	en	Rukmane-Bārbale, Anita, Acal, Dale Ann, Mohagan, Alma B.

Ecological notes: H. glendae sp. nov. abundantly inhabits the cloud pygmy forest ecosystem of Mt. Redondo, Dinagat Islands situated 10.21 ’ 3.26 ’’ N, 125 ’ 38 ’ 33.32 ’ E (Fig. 8). It is classified as forest over the limestone. Such ecosystems are characterized by their unique vegetation structure, with stunted trees from 0.4 m to 5.0 meters high with a nutrient- poor soils and harsh environmental conditions. The pygmy forest on Mt. Redondo is a distinct ecological niche. The Altitude is 894 masl. The vegetation is dominated by dwarf or stunted trees such as Agathis philipinensis (Alma- ciga), Cinnamomom mercadoi, Suararia sp., with gnarled branches, Cycas sp. (Pitogo), Nepenthes ssp (Pitcher plants), mosses, lichens, and epiphytes due to nutrient- poor 125 ultramafic soils, acidic conditions, and exposure to strong winds. The ultrabasic or serpentine soils with low nutrient levels, containing heavy metals and it is rich with chromite, nickel and several elements. The climate is wet and humid, with significant rainfall and moderate temperatures. It has high levels of endemism among flora and fauna. Along with the beetles, rare and brightly stick insects were spotted in the area. The major threats of fauna is habitat destruction - a large scale open pit mining that flattens some of the mountain peaks of the area as it is nationally declared as mining zone. Mining activities on Dinagat Islands, particularly in ultrabasic areas, pose a severe threat to the pygmy forest and its unique species. The Local Government Unit (LGU) of Dinagat Islands is engaged in conservation initiatives as it gave an ordinance to stop the mining activities in the area and converted it to a local conservation area as they promote tourism to ensure sustainable practices and minimize habitat degradation. H. glendae sp. nov. serves as a microcosm of the ecological uniqueness and vulnerability of the beautiful Mt. Redondo pygmy forest. Its conservation underscores the importance of protecting small, specialized ecosystems and the rich biodiversity they harbor. Differential analyses: The new species is similar to H. conicus Bohemann, 1844 (Mindanao population) by general brownish body without specific scally markings but can be distinguished by the following characters: 1) body of H. glendae sp. nov. significantly bigger, legs thicker than in H. conicus Bohemann, 1844; 2) elytra in dorsal contour strongly convex after the midline in H. glendae sp. nov. while slender in H. conicus Bohemann, 1844; 3) prothorax of H. glendae sp. nov. with basal half straight in dorsal contour, posterior margin bulged, while prothorax of H. conicus Bohemann, 1844 incurved along middle of basal half, posterior margin indistinct; 4) in dorsal contour apex of elytra not visible because of 126 the sharp abruption angle in H. glendae sp. nov. while visible in H. conicus Bohemann, 1844; 5) different shape of male penis (6 G- H).	en	Rukmane-Bārbale, Anita, Acal, Dale Ann, Mohagan, Alma B.
