Pseudodineura parvula ( Klug, 1816)  

Tenthredo (Allantus) parvula Klug, 1816: 71   . Holotype ♀ (GBIF-GISHym2763; images: https://doi.org/10.6084/ m9.figshare.7881005) in ZMHB, examined. Type locality: Oesterreich [ Austria].

Tenthredo minuta Lepeletier & Serville, in Latreille et al. 1828: 570   . Syntype (s) ♀, may be in MNHN; environs de Paris [ France, Paris area]. Listed in synonymy of parvula   by Dalla Torre (1894). Primary homonym of Tenthredo minuta Christ, 1791   [ Hoplocampa minuta   ].

Pelmatopus heringi Enslin, 1921: 183   (key), 185. Syntypes ♀ ♂. Lectotype ♀ (GBIF-GISHym3483; images: https://doi. org/10.6084/m9.figshare.7881065) in ZSM, here designated. Type locality: Rüdersdorf [ Germany, Brandenburg]   . Paralectotypes: see under Specimens examined. New synonym   .

Taxonomy. After a first examination of three females from Switzerland reared from Pulsatilla alpina   , we thought that these might represent a species distinct from parvula   . Compared to European specimens reared from lowland Pulsatilla   species and Anemone sylvestris   , the specimens from alpina   are distinctive because of their differently proportioned flagellomeres: antennomere 3 1.25–1.45 × as long as antennomere 8, whereas in lowland specimens antennomere 3 1.53–1.80 × as long as antennomere 8. The three individuals reared from P. alpina   also seemed to differ in the only slightly curved long setae on valvula 3, and the median mesoscutal lobes flatter, with groove shallow and obsolete on posterior. However, the specimens from Russia (Sajan) possess antennomeres proportioned within the range normal for lowland European specimens, but with sawsheath setation and median mesoscutal lobes more like the Swiss specimens. We conclude that all these specimens are conspecific, but some genetic data for populations occurring at higher altitudes would still be desirable. Regarding the statement by Enslin (1921), that parvula   can be distinguished from heringi   by its deeper frontal pit and differently shaped sawsheath, we noted considerable variability in both of these characters, but found no correlation between the character state and the identity of the host plant from which they had been reared, i.e. Anemone sylvestris   versus Pulsatilla   . Having observed no stable differences between the lancets and male genitalia of specimens reared from these hosts, or genetic differences, we propose that heringi   should be treated as a synonym of parvula   .

Additional description. Body length: ♀ 2.5–3.5mm, ♂ 3.0–4.0mm. Pronotum completely black. Female: tegu- lae brown. Abdomen completely black. Lancet: Fig. 32. Male: tegulae black or brown. Sternum 9 black except for extreme apex. Penis valve: Fig. 22 View FIGURES 21–26 .

Total number of specimens examined: 14♀, 8♂.

Similar species. Of the species with black-marked femora, only the female of fuscula   has a somewhat similarly shaped sawsheath. When the shape of the sheath is not clearly visible, the smaller sawteeth on the lancet of parvula   will distinguish them. Externally, the male closely resembles the other two species with black-marked femora ( enslini   and fuscula   ), but can be separated by its penis valve (see key).

Life history. Host plants: Anemone sylvestris   ( Enslin 1921, Altenhofer & Pschorn-Walcher 2006: as P. heringi   ), and Pulsatilla   species (as P. parvula   ); P. patens ( Conde 1934)   , P. vulgaris   , P. grandis ( Pschorn-Walcher & Altenhofer 2000)   , P. narcissiflora ( Hering 1935)   , P. pratensis bohemica ( Kulfan 2008)   , and P. alpina ( Hering 1932)   .

Distribution. Central Europe, north to Estonia ( Taeger et al. 2006, as heringi   ), and eastern Siberia ( Sundukov 2017, as parvula   and heringi   ). Occurrence in Sweden: not known, but could be present, particularly where the host plants occur as native species.
