( Figs 4A – B and 5)

Type material. Holotype, female: / PHILIPPINES / Luzon , Madela, Disimungal / X. 2015 / local collector leg. / (typed on a white rectangular label) ; / HOLOTYPE / Female / Pseudapocyrtus madelaensis Rukmane-Bārbale, 2021 / det. Rukmane-Bārbale, 2021’’(typed on a red rectangular label).

Distribution. Philippines, Luzon Island, Madela Province.

Description. Female. Measurements: LB = 14.2; LR = 1.13; WR = 1.56; LP = 3.2; WP = 3.83; LE = 8.23; WE = 7.52. N = 1 for all measurements. Dorsal habitus as shown in ( Fig. 4A).

Head, prothorax, antennae and tarsus black, elytra, underside and legs red. Markings of shiny, metallic green, round to recumbent unevenly dispersed rare scales on prothorax dorsally, rest of boby without shiny scales.

Head moderately punctured, pubescent, lateral parts smooth. Eyes small, flat, unprominent from the outline of the head, peak just in the middle. Forehead 1.8 times as wide as eye width, nearly flat, dosrally with longitudinal medial groove from base to subapical part. Rostrum strongly pubescent, WR/LR = 1.38, dorsally bulging, with moderate transverse groove that does not reach inner edge of each eye.Antenna mingled with long, light hairs; scape widened apically; basal antennomere three times as long as wide, widened apically, 1.5 times longer than antennomere II; antennomere II 2 times as long as wide, longer than antennomere III; antennomeres III - VI subequal in size, same length and width, shorter than antennomere VII; antennomere VII subequal in size. Club nearly two times shorter than antennomeres I - VII together, nearly three times as long as wide.

Prothorax wrinkled, nearly globular,WP/LP = 1.19, disc with medial longitudinal groove; in dorsal view widest just after the middle; anterior edge slightly curved apically, posterior edge with subbasal groove, curved apically. Elytra strongly plumped, LE/WE = 1.09, strongly punctured, pubescent, each elytron dorsally with three longitudinal furrows; in dorsal view strongly widened from base to subbasal part, evenly widened to widest middle, gradually decreased to subapical part, apex raised; in lateral view rised to subbasal part, gradually widened to widest just before the middle, then gradually decreased, apex strongly elongated, curved downwards; LE/LP = 2.57, WE/WP = 1.96. Coxa and femur pubescent, tibia and tarsus mingled with light, longer hairs; apical part of femur darker, nearly black.

Female genitalia as illutrated in ( Fig. 4B).

Male unknown.

Differential diagnosis. The new species can be easily distinguished from rest of the species by shape of elytra dorsally: strongly widened, apex less raised and wider, and additional three furrows on each elytron that are not present for any other species; laterally apex strongly elongated and curved downwards, much bigger than in rest of the known species ( Fig. 5). Eyes are strongly flattened compared to rest of the species

Etymology. The species name is dedicated to geographic locality where species is originally reported.
