E t y m o l o g y: The species name is derived from its predominant distribution area in the Friuli-Venezia Giulia region.
D e s c r i p t i o n: Habitus as in Fig. 1. Body length 1.07-1.15 mm. Body including appendages dark reddish-brown; shiny, moderately dense, long and weakly raised hair. Head shiny, unpunctuated, with eyes clearly protruding laterally and sharply delimited towards the back. Antennal segments 1 and 2 distinct, 3-7 very slightly longer than wide, 8 spherical and much smaller than 7, its three-part club sharply set off. Pronotum one-third wider than long (1.3: 1), shiny with fine and widespread punctures, greatest width just before the middle, evenly strongly rounded towards the front, straight rounded converging narrower towards the back. In males, the centre of the pronotum is very weakly elevated before the base. Elytra narrower than long (1: 1.3), shiny and compared to the pronotum with noticeably coarser, denser, and weakly rasp-like punctures; greatest width just before the middle, sides evenly rounded. The basal pits not exactly round, laterally and posteriorly flattened, tomentum cushion at the inner front edge. In males, the anterior half of the front tibiae is weakly thickened, with a distinct indentation towards their tip on the inner side (Fig. 4). Underside:♁ Metaventrite weakly depressed, highly shiny, very finely and thinly haired, scarcely recognizable punctate (Fig. 3). Genitalia: Length 0.32 - 0.35 mm. Dorsal Fig. 2 & 79., lateral Fig. 5.
The drawing of the internal genitalia structures from Besuchet (Fig. 84) show only one layer of the spatial structure and is therefore incomplete pictured.
