( Fig. 1-8 View Fig View Figs View Figs View Fig View Fig View Fig View Fig )

Type material. Holotype (♂): Philippines, N Luzon, Barlig Mt. Province , April 2016, local collectors, ( JHAC) . Paratype: (1 ♀): same data as holotype, ( JHAC). Type material is incomplete (without legs and antennomeres) .

Description of male. Body flat, length from anterior margin of clypeus to apex of elytra measured along the median line: 6.5 mm. Surface black; antennae and legs black, abdomen darkish brown. Surface well encrusted ( Fig. 1 View Fig ).

Head ( Fig. 3 View Figs ) Transverse, rounded. Eyes large, longer than wide, prominent. Temples moderate in size, relatively broad, length about 1/5 of eye. Dorsal punctation dense, strong; ventral surface with denser punctation than dorsum. Paired distinct longitudinal small cavities on ventral neck. Labrum semicircular, with dense setation, with many short to long setae except basally. Antennae relatively thick and long; setation moderately dense. First antennome long ( Fig. 2 View Figs ). Mandibles triangular, bidentate, teeth protruding apically, with a wide tooth on inner tooth wider than outer, with many dense, thin setae along inner margin and few long setae somewhat densely clustered around outer lateral margins; molae widely protruding posteriorly; mycangial cavities small, located basally; male mandibular horn stout dorsally, located on anterior outer lateral margin, with many medium length setae. Thorax and Abdomen. Pronotum square, longer than wide, including lateral teeth ( Fig. 4 View Fig ). Mesoventrite relatively narrow, length about half of pronotum, metaventrite moderately large, about 1.5 times wider than mesoventrite; intercoxal process of mesocoxae narrow, a little wider than intercoxal process of procoxae; intercoxal process of metacoxae narrow, a little narrower than intercoxal process of procoxae. Punctation comparatively dense on pronotum, posterior half of prosternum, meso- and metaventrite, relatively sparse on anterior half of prosternum. Abdomen ( Fig. 5 View Fig ) brown, about twice longer than width, covering about 3/5 of underside of elytra; punctation almost same density as on metaventrite.All abdominal visible ventrites with two, small, narrow depresions.

Elytra. Elongate, length measured along median line maximum combined width 4.3 mm. Punctures narrower than interstices. Lateral margins very narrowly flattened, flattened areas extended to around anterior angles.

Male genitalia as in ( Fig. 7-8 View Fig ).

Sexual dimorphism. Female similar to male. Body length from anterior margin of clypeus to apex of elytra measured along the median line: 5.9 mm. Mandibles with short teets. First antennomere shortly as in male.

Differential diagnosis. This species is similar to Parahyliota serrata (Smith, 1851) and P. serricollis (Candeze, 1861) , but can be distinguished by the following characters:

1. Male with frons deeply excavate and emarginate over antennal insertations ..... P. serricollis (Candeze)

2.Male with frons foveate, but otherwise inmodified:

- Temple longer, a fourth or more the diameter of the eye; antennae very elongate, but antennomeres not modified in male; male without mandibular horns; colour black …….. P. barsevskisi sp. nov. - Temple shorter; male with mandibular horns; colour brown ………………. P. serrata (Smith)

Etymology. The species name I dedicated to my friend and colleague Arvids Barševskis (Daugavpils, Latvia) as well known specialist in Cerambycidae and Carabidae ( Coleoptera ).
