Redescription ( Figs 1C–D , 4D ). Body length 3.56–4.63 mm. Body black, antennae and legs reddish, in some specimens clubs and middle part of femora darker. Elytra densely covered with short oval, greyish appressed scales, integument hardly visible, 4–5 scales across one interval; elytra without any pattern, only interval 7 with slightly more whitish scales in some specimens; intervals 2 and 4 in some specimens somewhat narrower than the others; intervals with one sparse row of very short, indistinct, slender setae, hardly visible also in lateral view. Pronotum densely covered with white greyish, short oval, pointed scales, completely covering integument, bigger than elytral scales, with irregularly scattered, slender, almost piliform setae of the same colour; lateral parts of pronotum with somewhat larger whitish scales, forming indistinct longitudinal stripes. Head and rostrum regularly covered with greyish short oval scales, hiding integument.

Head ( Figs 1C–D ; 4D ). Rostrum short and wide, isodiametric; in basal half faintly tapered anteriad, with straight sides, in apical half distinctly enlarged anteriad with straight sides, at apex 1.08–1.14× as wide as at base. Frons flat, finely punctate, shiny. Epifrons coarser punctate, somewhat matt. Eyes small, moderately convex, somewhat projecting beyond outline of head.

Antennae with funicle segment I 1.8–2.0× as long as wide; segment II 2.4–2.5× as long as wide and 1.1× as long as segment I; segment III 1.4–1.5× as long as wide; segments IV–VI 1.1–1.2× as long as wide; segment VII isodiametric; clubs 2.6–2.7× as long as wide.

Pronotum ( Figs 1C–D ) wide, 1.39–1.43× as wide as long, widest behind midlength, with distinctly rounded sides, anteriad more tapered than posteriad; disc regularly and densely punctate, distance between two punctures shorter than puncture diameter.

Scutellum small, triangular, glabrous.

Elytra ( Figs 1C–D ) short oval, 1.32–1.39× as long as wide, somewhat globose, widest at midlength, with distinctly rounded sides; humeral calli regularly rounded, not projecting laterally; striae punctate, wide; intervals almost flat.

Legs. Pro- and mesofemora with small, almost indistinct tooth, metafemora with small but well visible tooth. Tarsomere II isodiametric to 1.1× as wide as long; tarsomere III 1.4–1.5× as wide as long and 1.6–1.7× as wide as II; onychium 1.1× as long as tarsomere III.

Sexual dimorphism. None, parthenogenetic species.

Female genitalia. Spermatheca ( Fig. 6B ) with ramus and nodulus equally wide, ramus twice as long as nodulus.

Differential diagnosis. Among not greenish species, distinguishable by equal size of greyish scales of dorsal part of body, lack of brownish scales forming longitudinal stripes on pronotum or elytra ( Figs 1C–D ).

Distribution. Albania ( BOROVEC 2013), Austria ( BOROVEC 2013), Bosnia and Herzegovina ( DIECKMANN 1980), Croatia (unpublished data), Czech Republic ( DIECKMANN 1980), Germany ( DIECKMANN 1980), Hungary ( DIECKMANN 1980), Montenegro (unpublished data), Poland ( DIECKMANN 1980), Romania ( BOROVEC 2013), European part of Russia ( DIECKMANN 1980), Slovakia ( BOROVEC 2013), Ukraine ( DIECKMANN 1980). The presence of the species in Sweden is doubtful as it was based only on the type specimen of C. rubi and was never confirmed by new material.

Collection circumstances. Numerous specimens were collected by general sweeping of a meadow bank of the Elbe River in eastern Bohemia, Czech Republic ( Fig. 9B ) by one of the authors.

Remarks. Thylacites ningnidus was described from ‘Halae Saxonum’ ( Germar 1824) and there are four specimens in the Germar’s collection (MLUH), pinned below handwritten label: ‘ ningnidus Gm Schönh., Halae, Jnr. ’. We designate a lectotype of T. ningnidus from a well-preserved female specimen to stabilize the nomenclature in the group.All three remaining syntypes are conspecific with the lectotype and we have designated them as paralectotypes.

Curculio rubi was described from ‘Habitat in Rubo Caesio Scaniae. Rarius, Dom Wetterhall’ ( GYLLENHAL 1813). There is one specimen in NHRS from the type locality; however, we have not seen all type material from Gyllenhal’s own collection (housed at the Uppsala University) and therefore we do not designate a lectotype. On the other hand, we consider the NHRS specimen a possible syntype as it comes from the type locality; its labels indicate that it came from the same time period as Gyllenhalʼs specimens. The specimen is in accordance with the concept of the species as used in the literature and is without all doubts conspecific with the type of Curculio rubi . However the name is preoccupied as Curculio rubi Gyllenhal, 1813 is a junior homonym of Curculio rubi Herbst, 1795 (presently Anthonomus rubi ), and therefore Sciaphobus (Neosciaphobus) ningnidus ( Germar, 1824) is used as a valid name for this species ( BOROVEC 2013).
