Pseudodineura clematidisrectae Hering, 1935

Pseudodineura clematidis-rectae Hering, 1935 : XII. Holotype ♂ (GBIF-GISHym2807; images: https://doi.org/10.6084/ m9.figshare.7880444) in ZMHB, examined. Type locality: Karlstadt ( Maintal ) [ Germany, Bavaria].

Pseudodineura mocsaryi Zombori, 1976: 211–213 . Holotype ♀ (DEI-GISHym31821; images: https://doi.org/10.6084/ m9.figshare.7880555) in HNHM, examined. Type locality: Karst [region in south-west Slovenia]. New synonym.

Pseudodineura scaligera Zombori, 1979: 237–238 . Holotype ♀ (DEI-GISHym31814; images: https://doi.org/10.6084/ m9.figshare.7880669) in MSNG, examined. Type locality: Turbigo (Lomb.), Ponte Ticino [ Italy, Lombardy]. New synonym.

Taxonomy. Zombori (1976) compared his mocsaryi with a syntype female of clematidis . He did not mention clematidisrectae , and it seems likely that this taxon was unknown to him. Some of the differences noted by Zombori are characters which we also found to be useful in separating clematidis and clematidisrectae , but the holotype of mocsaryi is apparently somewhat faded, particularly the abdomen. In our opinion, all other characters of mocsaryi fit clematidisrectae , and we therefore consider them to be conspecific. Again, in his description of scaligera, Zombori (1979) does not mention clematidisrectae . Instead, he states that because of its similarly structured face, scaligera “belongs to the mentiens - parvula species pair”. He supposed that the strongly bent posterior part of vein M of the scaligera holotype was an especially valuable diagnostic character, separating it “from all other congeners”. In fact, this character is more or less variable in several Pseudodineura species, and the vein is often strongly bent in clematidisrectae . Neither do other characters of scaligera differ from clematidisrectae , and we therefore treat them as synonyms.

Additional description. Body length: ♀ 4.5–5.0mm, ♂ 4.5mm. Black: anterior edge of clypeus sometimes pale. Tegulae pale. Pronotum completely pale, to black with pale dorsal and posterior edges. Female: at least parts of some apical abdominal terga and sterna pale, and sometimes also distal part of valvula 3. Lancet: Fig. 28. Male: sternum 9 and more or less parts of adjacent terga and sterna pale. Penis valve: Fig. 24 .

Total number of specimens examined: 19♀, 7♂.

Similar species. Most similar is Pseudodineura clematidis : see there. The female of enslini has a similarly shaped sawsheath, but apart from its darker femora, the lancet is probably distinguishable: see under enslini .

Life history. Host plant: Clematis recta ( Hering 1935, Altenhofer & Pschorn-Walcher 2006).

Distribution. Central Europe ( Taeger et al. 2006), south to Slovenia ( Maček 1974). Occurrence in Sweden: published records; none. Material examined: no Swedish specimens; a specimen standing in the NHRS collection under this name is enslini .

Specimens examined. Austria: 7♀, 6♂, reared from Clematis recta ( SDEI, ZSM) . Including : Lower Austria , 1♂ (DEI-GISHym31889), Zöbing , 23.05.1993, em. 29.04.1994, Clematis recta , leg. E. Altenhofer ( SDEI) . Germany: 10♀, netted from C. recta ( SDEI) . Including : 1♀ (DEIGisHym11441), Bavaria, Lower Bavaria, Landkreis Dingolfing-Landau, Rosenau , 13.05.2004, leg. Liston ( SDEI) . 1♀ (DEIGisHym31880), same locality as preceding, but coll. 12.05.2004 ( SDEI) . 1♀ (DEIGisHym11442), same locality as preceding, but coll. 16.05.2003 ( SDEI) .
