Rukmane, Anita, 2019, Two New Species Of The Genus Macrocyrtus Subgenus Exmacrocyrtus Schultze, 1924 (Coleoptera: Curculionidae: Entiminea) From Luzon Island, Philippines, Acta Biologica Universitatis Daugavpiliensis 19 (2), pp. 261-266 : 264-266

Macrocyrtus (Exmacrocyrtus) fulgidus sp. nov.

Fig. 2 A-D, 3.

Differential analyses. Macrocyrtus (Macrocyrtus) fulgidus sp. nov. on general appearance is similar to Macrocyrtus (E.) erosus ssp. auroanulatus Heller, 1929 but is readily distinguishable from this species by various morphological features:1) elytra of the new species smooth, slim, apex extended, in M. (E.). erosus ssp. auromaculatus elytra wider, gradually rounded in derection to apex, apex not extended; 2) unique markings on elytra and pronotum; 3) rostrum of the new species with relatively deep (for the current genus) lanceolate impression, that is shallow in

M. (E.) erosus ssp. auromaculatus ( Fig.4 ).

Description. Male. Dimensions. LB: 12,8 – 13,4 (Holotype 13,4; mean 13,1); LR: 1,9 (Holotype 1,9; mean 1,9); WR: 1,5 (Holotype 1,5; mean 1,5); LP: 3,5 – 3,7 (Holotype 3,7; mean 3,6); WP: 3,3 – 3,4 (Holotype 3,4; mean 3,35); LE: 9,2 – 9,9 (Holotype 9,9; mean 9,55); WE: 6,0 – 6,2 (Holotype 6,2; mean 6,1). N=2 for all measurements. Habitus as shown in Fig. 3 .

Integument black, shiny; body, antennae and legs black, shiny, with markings of dazzling blue to green scales; underside with weaker lustre, with markings of dazzling blue to green round to recumbent scales on metasternum, mingled with long, light hairs, strongly pubescent; metacoxa with line of elongated green dazzling scales along internal margin.

Head sub ovate, finely punctured and slightly pubescent; genae with few elongated scales, mingled with long white hairs up to ventral part; forehead wrinkled between eyes, nearly 1,5 times as wide as eye width, without scales; rostrum strongly pubescent, with moderate long light hairs from antennal scape to labrum; in dorsal contour nearly straight; dorsally with longitudinal groove from middle of rostrum to sub basal part of forehead, lanceolate impression; eyes slightly convex, relatively big, moderately prominent from the outline of the head. Antennae slender; segments I and II sub-equal in size, nearly 3 times longer than wide; segments III to VII sub equal in size, gradually increasing from segment III to VII; club lanceolate, nearly 2,5 times as long as wide. Rostrum longer than wide, LR/WR 1,27.

Prothorax sub cylindrical, almost sub equal in length and width, LP/WP: 1,09, with the following scaly markings: 1) two patches consisting of few scales along apical margin, each redirected laterally; 2) a pair of patches consisting of few recumbent scales slightly below middling, each redirected laterally; 3) ovate patch of scales on each lateroventral part; finely punctured, moderately pubescent; widest just in the middle, in dorsal contour smallest width along apical margin, then increased to widest midline, firmly rounded and weakly decreased in direction to basal margin, along sub-basal part slightly incurved.

Elytra sub-lanceolate, widest just in the middle; in dorsal contour slightly squeezed out along basal margin, gradually increased to widest middle, then gradually decreased to apical 1/5 where extended in direction to apex; each elytron with the following scaly markings: 1) irregularly dispersed roundish scales along sub basal part from slightly before suture to lateral margin; 2) roundish patch medially near suture; 3) short transverse line medially along lateral margin; 4) irregularly dispersed set of scales from apical ½ in direction to apex; LE/WE: 1,6; wider and longer than prothorax, WE/WP: 1,82, LE/LP: 2,57; nearly smooth on entire length, without clearly expressed intervals, pubescent in all length; short, light hairs along apex.

Front and middle coxa without scaly markings; front coxa with relatively long, rare, light hairs; femora without scally markings, sparsely covered with longer or shorter light hairs, pubescent; tibia with long light hairs along internal margin and on apical part; tibia with protrusions along internal margin, each prostration with brownish spike, protrusions on hind tibia fairly bigger than those on the from tibia.

Aedegal body as shown in Fig. 2 A-D.

Female. Elytra much wider, in dorsal contour widest in the middle; protrusions on hind tibia smaller, otherwise as in males.
