Acronia marifelipeae sp. nov.

( Fig. 1A , 2 )

Type material. Holotype, female: Philippines: Luzon Isl., Nueva Vizcaya, Belance , 05.2015, local collector leg.

General distribution: Philippines: Luzon Island ( Fig. 2 ).

Description. Body subcylindrical, elongate, black, lustrous. Surface black, median part of elytra with green metallic luster and with pale brown to brown spots of scalish pubescence. Length: 19.0 mm, width: 6.5 mm.

Head flat, wide, almost parallelsided, with slightly convex eyes and slightly extended cheeks covered with dark sparse pubescence in anterior part and dense white pubescence basally under eye. Surface of head black, shiny, with sparse and coarse punctures, interspaces between punctureswith very thin, sparse micropunctures and flat, wavy microsculpture. Median part of head with longitudinal thin linebeginning fromfrontal portion near clypeus and extendingto base of head; median part of this line distinctly elevated Head with two elongated brown spots between basal part of antenna. Labrum dark brown, pubescent, slightly convex, with dark hairs and punctation. Clypeus black, narrow, transverse, shiny, with delicate pubescence. Mandible shiny, massive, relatively wide and sharp. Antennae black, apical part dark-brown and relatively short, covered by dense dark pubescence; antennomere 1 thickened, with sparse punctures between very fine pubescence; basal part of antennomere 4 with white pubescence.

Pronotum almost cylindrical, very convex, frontal part with sparse punctures and acute, extended basal angles. Basal part of pronotum not convex, neck-shaped, with elongated two brown spots laterally. Dorsal disc of pronotum without distinct median line. Scutellum small, rounded apically.

Elytra black, glossy, finely punctated, each elytron with well developed humps behind shoulders. Dorsal part of elytra behind shoulders and around scutellum with wide impression. Elytra mostly covered with black pubescence, each elytron with eight brown and white-brown spots. Elytra behind shoulders and on apex smooth and shiny, flat, without pubescence. One elongated brown spot located behind scutellum at suture, one larger spot at shoulders, two large spots in apical part, and, below, with third thin brown line-shaped spotlocated. Dorsal portions of each elytron with two yellow-brown spots. Middle part of elytra and portion below spots with wide metallic green strip covered laterallyby fine white pubescence. Apex of elytra without visible projections.

Upper side of body black, with brown spots. Legs relatively short, slightly shiny, covered with dark pubescence. Tarsomeres black, covered by yellow brown pubescence in upper side.

Differential diagnosis. New species similar to A. roseolata Breuning, 1947 ( Fig. 1B ), from which it differ by the following characteers: 1) pronotum of A. marifelipeae sp. n. black (pronotum of A. roseolata indistinctly violet); 2) elytra of new species with two pairs of symmetrically located dorsal yellow-brown spots, scutellar spots more angular (elytra of A. roseolata without dorsal spots, scutellar spots more oval); 3) basal part of 4th antennomere with white pubescence(– basal parts of

3rd and 4th antennomere of A. roseolata without white pubescence).

Etymology. This species is named after Mari Felipe ( Philippines: Calumpit) who kindly donated type specimen for my study.
