Medium sized, dark, macropterous Phlaeothripinae with short, hyaline setae on head and pronotum, abdominal lateral setae longer. Head about as long as wide, constricted at base behind convex genae; vertex coarsely reticulate laterally and on hind margin but smooth medially; postocular setae tiny; mouth-cone short and rounded; maxillary stylets retracted as far as postocular setae, close together, with a distinct maxillary bridge. Antennae 8-segmented; segment III with one outer sense cone, IV with 2 (1+1) sense cones; VIII constricted at base; sensorium on antennal segment II almost on basal half of segment. Pronotum wider than long, slightly trapezoidal, with two pairs of major setae developed but not long; notopleural sutures complete. Prosternal basantra sub-circular in females but much longer than wide in large males; ferna transverse; mesopresternum extended forwards medially; metathoracic sternopleural sutures present. Fore tarsal tooth present in both sexes. Fore wings not constricted medially, without duplicated cilia. Pelta bell-shaped, usually with small posterolateral wings; tergites II and VII each with only one pair of wing retaining setae, III‒VI each with two pairs; tergite IX setae S1 and S2 pointed, less than half length of tube. Male tergite IX setae S2 stouter than but not shorter than S1; sternite VIII apparently without pore plate.
The remarkably well-developed and sexually dimorphic prosternal basantra are particularly unusual, but the species seems most likely to be derived from within the Phlaeothrips-lineage. Despite the position of the sensorium on antennal segment II, Okajima (1981) considered that this genus is not a member of the Plectrothripini, but is more closely related to Hoplothrips.
Recorded from the bark of dead Pinus silvestris trees, and presumably fungus-feeding.
Recorded across Central Europe, south from Finland.
