Description.

Dimensions: LB: 8.4 mm. LR: 1.1 mm. WR: 1.1 mm. LP: 2.5 mm. WP: 2.5 mm. LE: 5.8 mm. WE: 4.0 mm. N = 1. Integument dark brown. Body surface, rostrum, head, legs matte, and underside weakly lustrous. Head dorsal surface weakly punctate and each puncture with subappressed white piliform scales; lateral side with weak rugae and sides below eye with sparse appressed bluish piliform scales; forehead between eyes flat with distinct but faint midline groove; eyes medium-sized, feebly convex, and moderately prominent on lateral outline of head. Rostrum dorsal surface weakly rugose up to anterior two-thirds with appressed white piliform scales; apical third finely punctate with fine sparse setae; as long as wide (LR/WR:1.1 mm/1.1 mm); transverse groove at base absent; with midline groove distinct until middle and progressively fainter and indistinct towards apex; dorsal contour flat, slightly curved towards apex but without apical bulge; lateral sides at upper margin of antennal scrobe with subtriangular depression. Antennal scape slightly longer than funicle, scape reaching beyond the posterior margin of eye, with few sparse subappressed pubescence, and funicle with suberect brownish setae. Funicular segment I nearly four times as long as wide, slightly longer than II, funicular segment II nearly three times as long as wide, longer than segments III-V, segments III-V as long as wide, shorter and narrower than VI, segment VI as long as wide, longer and wider than segments III-V, segment VII as long as wide, wider and longer than segments VI; club lanceolate. Prothorax subcylindrical, significantly wider at posterior margin then narrowed towards anterior margin, as long as wide (LP/WP:2.5/2.5 mm), coarsely punctate and rugose with sparse appressed white piliform scales and lanceolate pale turquoise and pale blue scales, widest at base, dorsal contour flat. Elytra pyriform (LE/ WE:5.8/4.0 mm), moderately longer than wide; moderately longer and wider than prothorax (WE/ WP: 4.0/2.5 mm, LE/LP: 5.8/2.5 mm); elytral surface coarse and with granulately rugose intervals, sparsely covered with minute white appressed piliform scales and pale turquoise and pale blue lanceolate scales, dorsum weakly convex, lateral contour widest before middle. Legs. Mid and hind femora dark brown covered with white subappressed piliform scales. Mid tibiae covered with white subappressed piliform scales on outer edge and suberect brown setae along inner edge. Hind tibiae covered with subappressed white piliform scales on outer edge and suberect brown setae along inner edge; inner edge and part of outer edge coarsely granulated. Mid and hind tibiae mucronate. Tarsomeres pubescent. Coxae with sparse appressed pale blue and white piliform scales. Mesoventrite with sparse appressed pale blue lanceolate scales and white setae. Metaventrite and ventrite I weakly depressed on disc, mostly glabrous except distal ends with appressed pale blue and pale-yellow lanceolate scales and white piliform scales. Ventrite II with sparse pale blue and yellow lanceolate scales and white setae. Ventrite III to V with fine sparse brown setae.

Female (PNM 15219). Dimensions: LB: 8.0 mm: LR: 1.1 mm: WR:1.1 mm.LP: 2.5 mm. WP: 2.5 mm. LE: 5.8 mm. WE: 4.1 mm. N = 1. Habitus, as shown in Figs 12 , 14 . Females differ from males in the following: a) fore tibiae flat; b) pronotum narrower with more flat dorsal contour; c) elytra moderately wider, and slightly longer; d) ventrite I flat. Otherwise, it is similar to the male.

Diagnosis.

The new species is easily distinguished from the only known species, Enoplocyrtus marusan Yoshitake, 2017, based on the following morphological characteristics: a) coarsely punctate and rugose pronotum, b) elytral surface coarse and with granulately rugose intervals, c) integument dark brown, d) pronotum and elytra sparsely covered with appressed white piliform scales and pale turquoise and pale blue lanceolate scales, and e) differently shaped aedeagus (Figs 15 , 16 ).

Etymology.

The name " angelalcalai " is dedicated to National Scientist Angel Chua Alcala (1929-2023, Dumaguete, Negros Oriental, Philippines) for his contributions to advancing the Philippines’ herpetological and marine research and conservation. Additionally for inspiring the authors to work on biodiversity research and conservation in the Philippines.

Distribution.

Enoplocyrtus angelalcalai sp. nov. is known only from the type locality in Palapag, Bontoc, Mountain Province (Fig. 21 ).
