Redescription ( Figs 1E–H , 4B–C , 5B ). Body length 3.69–4.51 mm. Body black, frons reddish, antennae and legs reddish-brown, in some specimens clubs and femora darker, dark brownish. Elytra with small, short oval, ligth brownish and appressed isolated scales, 7–8 scales across one elytral interval; elytral intervals 7 and 8 with slightly larger whitish- grey scales, identical scales also in short basal part of elytral interval 3 and irregularly sparsely scattered among brownish scales on whole elytra; all elytral intervals with 1–2 sparse, irregular rows of very short, slender, adherent and bronze setae, hardly visible also in lateral view. Pronotum with transversally directed long oval narrow brownish scales of unequal width, larger than elytral scales and with big long oval greyish scales forming inconspicuous longitudinal lateral stripes. Head with rostrum with sparse narrow, long oval scales, obliquely directed posteriad, almost regularly covering whole area, only around eyes scales larger and denser.

Head ( Figs 1E–H , 4B–C ). Rostrum isodiametric, in males somewhat slenderer than in females; basal half weakly tapered anteriad with straight sides, apical half distinctly enlarged anteriad with almost straight sides, at apex 1.07–1.13× as wide as at base. Frons glabrous, sparsely and finely punctate, shallowly depressed. Epifrons regularly densely punctate, somewhat matt. Interocular space with short fovea. Eyes small, convex, projecting beyond outline of head.

Antennae in females slenderer than in males; in males funicle segments I and II equally long, segment I 1.6–1.7× as long as broad; segment II 1.5–1.6× as long as broad; segment III and IV 1.1× as long as broad; segment V and VI isodiametric; segment VII 1.1–1.2× as broad as long; in females segment II 1.2× as long as segment I; segment I 1.5–1.6× as long as broad; segment II twice as long as broad; segments III–VI 1.4× as long as broad; segment VII 1.1–1.2× as long as broad; clubs 2.6–3.1× as long as broad.

Pronotum ( Figs 1E–H ) wide, in males 1.18–1.23× as wide as long, in females 1.27–1.29× as wide as long; widest at midlength, with rounded sides, anteriad more tapered than posteriad; disc regularly and densely punctate, intervals among punctures form only narrow, shiny keels; disc with thin, impunctate, ill-defined longitudinal median area.

Scutellum small, triangular, glabrous.

Elytra ( Figs 1E–H ) short oval, somewhat globose; in males slightly narrower than in females, 1.26–1.28× as long as broad, whereas in females 1.24–1.26× as long as broad; humeral calli not projecting, regularly rounded; striae punctate, narrow; intervals wide and flat.

Legs. Pro- and mesofemora in males with small but distinct tooth; metafemora with big, conspicuous tooth; pro- and mesofemora in females with very small, almost indistinct tooth; metafemora with large tooth, somewhat smaller than in males. Tarsomere II 1.3–1.4× as wide as long; tarsomere III 1.4× as wide as long and 1.5–1.6× as wide as II; onychium short, 0.7–0.8× as long as tarsomere III.

Sexual dimorphism. For more details see rostrum, antennae, pronotum, elytra and femora.

Male genitalia. Aedeagus ( Fig. 5B ) long and slender, in ventral view parallel-sided, apex regularly pointed, subtriangular, with indistinct concavity before apex; in lateral view regularly curved and of equal width in basal half and then regularly tapered apicad.

Female genitalia. Spermatheca ( Fig. 6A ) with ramus somewhat larger than hump-shaped nodulus.

Differential diagnosis. Among brownish species easily distinguishable by large tooth in metafemora in both sexes, females by wide elytra ( Fig. 1G ), males by aedeagus in lateral view tapered in apical half of the length ( Fig. 5B ).

Distribution. Albania.

Remarks. Apfelbeck’s description was based on a single specimen: ‘ Albania merid. In monte Šen Thanas prope Valonam a dom. Hoppe (berolinensi) inventum. (Specimen unicum J; ♀ ignota). Typus in coll. Noeske (dresdensi).’ According to R. Krause (pers. comm.), the collection of Noeske has not been deposited in SMTD. But among various Polydrusus species , one male specimen from the type locality was found in SMTD, it fits well the primary description and has the same locality data. Althoug it has no Apfelbeck’s label with species name, we can assume that it is the missing holotype in the general collection of Sciaphobus in SMTD.
