(holotype male): a) habitus (scale: 0.75 mm); b) head (scale: 0.43 mm); c) left scapus in dorsal view (scale: 0.1 mm); d, e) abdominal tergite VIII – ventral and posteroventral views (scale: 0.17 mm); f, g) aedeagus – dorsal and lateral view (scale: 0.14 mm). with sparse, long, golden, suberect setation. Frons with well-defined but shallow impression between antennal tubercles, bordered by 2 lateral carinae; rostrum prominent, in dorsal view extended to anterior margin of clypeus and covered with short, erected, golden setae. Median longitudinal occipital carina well defined; vertexal foveae deep, situated close to a hypothetical line joining anterior margins of eyes. Eyes small but well visible in dorsal view, each composed of 10–14 facets. Maxillary palpi long, palpomere I pedunculate, palpomere II very small, palpomere III 0.25–0.27 mm long. Antennae relatively short ( 0.58–0.59 mm ), when bent backwards slightly exceeding base of elytra; scape ( Figure 2c ) about twice as long as wide; pedicel simple, slightly longer than wide ( 0.068 / 0.051 mm ); antennomere III as long as pedicel; IV–VI subequal in length, each about 0.034 / 0.034 mm ; VII wider than long ( 0.017 / 0.034 mm ); VIII as long as wide, about 0.017 / 0.017 mm ; IX about 3 times as wide as long ( 0.051 / 0.017 mm ); X about twice as wide as long ( 0.068 / 0.034 mm ); XI about twice as long as wide, acute at apex. Pronotum (0.34/ 0.37 mm ) covered with long, recumbent, dense setae, widest in anterior half, 1.20–1.30 times as long as head. Elytra (0.59/ 0.63 mm ), 1.75 times as long as pronotum, covered with long, suberect setae. Terminal abdominal tergite (VIII) strongly modified ( Figures 2d and 2e ). Legs with robust femora and slender tibiae, pro- and mesotibiae simple, with short, robust setae in the internal apical part only, metatibiae with short internal apical spur. Aedeagus 0.27–0.28 mm long ( Figures 2f and 2g ). Sexual dimorphism: Female with eyes composed of 4–5 ommatidia; frontal lobe with small, not as prominent as in the male, rostrum. Scapus simple, longer than wide ( 0.085 / 0.051 mm ); pedicellus simple ( 0.068 / 0.034 mm ). Apical part of abdomen without modifications. Differential diagnosis: Bryaxis fronticornis sp. nov. belongs to the Bryaxis curtisii species group, as defined by Besuchet and Kurbatov (2007) . The frontal lobe is bigger than half of the head, bearing secondary sexual characters; the metafemur has a line of setae on the inner part. The new species differs from all other members of this group in the shape of scapus and pedicel, the structure of aedeagus, and by the unique modifications of the last abdominal tergite. Etymology: The name refers to the prominent hornlike projection of the frontal lobe.
