Brachysomus moczarskii Penecke, 1924: 14 . Type locality: Greece, Mt. Pelion; Dalla Torre et al. 1937: 174; oertzeni: Košťál 1992: 38 .

Redescription. Measurements: Body length 2.07– 2.65 mm, width—1.20–1.45 mm. Vestiture: Head, body, and legs densely covered with, small, grayish, wide, excised apically, recumbent scales. Elytral interstriae and antennal scape covered with suberect, light, short, evenly widened, round apically setae; length of setae at basal half of elytra less than at apical half, 2.5x shorter than width of interstriae. Funicle with thin pale hairs. Abdomen covered with pale hairs and piliform scales. Colouration: Body, legs and antennae brown.

Head: Rostrum strongly conical from base to middle, moderately longer than width. Pterygia distinctly projecting from outline of rostrum. Epifrons convex longitudinally, separated from vertex by transverse depression. Vertex flat, rugose, as wide as base of epifrons. Eyes small (VW/ELD = 2.0), weakly convex, situated almost at level of vertex.

Antennae: scape distinctly curved, evenly widened distally; funicular antennomeres: 1st and 2nd elongate, 1.5x as long as wide, 1st noticeably larger than 2nd; 3rd–7th transverse in male, almost as long as wide in female, at most 7th transverse; club egg-shaped or narrowly egg-shaped.

Thorax: Pronotum transverse [PL/PW = male: 0.81, female: 0.73–0.79 (0.77)], weakly constricted anteriorly, evenly convex at sides, densely, shallowly punctate; disc weakly convex. Elytra: oblong-oval, weakly convex at sides and disc. Striae narrow, punctures weakly separated, 2x narrower than interstriae; interstriae distinctly convex, shiny. Legs: robust, femora distinctly swollen in middle part; tibiae straight externally, and weakly S-shaped at internal side, not widened externally. Hind tibiae in male with large mucro. Second tarsomere weakly transverse, 3rd with large lobes. Fifth fore tarsomere extending beyond apical lobes of 3rd by length of the lest.

Abdomen: Male 5th ventrite with distinct depression; apical margin of 5th ventrite straight. Male genitalia: Median lobe slightly sclerotized, 2x shorter than apodemes; endophallus with small thorn-shaped distal sclerite, distal spiculate fields consist of small broad spiculae, proximal field consists of large long spiculae. Spermatheca with large, emarginate ramus.

Diagnosis. Brachysomus moczarskii is similar to B. albanicus , differing in the depression on the male 5th ventrite, structure of the genitalia in both sexes, oblong rostrum and elytra. From B. oertzeni it differs in the above listed characters as well as in strongly developed pterygia, epifrons with distinct transverse depression, at the base distinctly narrower than the vertex.

Distribution. Greece (Thessaly).

Bionomics. Unknown.

Remarks. This species has been described from Thessaly, and then been synonymized with B. oertzeni ( Košťál 1992) . Examination of types and additional material revealed that B. moczarskii is a separate species, clearly different from B. oertzeni (see diagnosis).
