Isogenus nubecula Newman 1833
No full textIsogenus nubecula Newman 1833 Buskerud: Sigdal, Tempelbekken, Norefjell, 1.x.1966, 1 nymph [slide marked P258, bearing nymphal pronotum, leg, cercus and maxilla] This is an inhabitant of large lowland rivers that was once rather common in central and northern Europe. It suffered a dramatic decline in most of its range due to pollution and habitat fragmentation (Zwick 1992, 2004; Fochetti & de Figueroa 2006; Koese 2008: 91). It is a rare species in Scandinavia as well (Hoffsten & Malqvist 2003). The material in the NHM contains no complete specimen. The Norwegian data portal Artskart contains two observations of these species based on collection specimens. As these were collected in the province of Troms, outside of the species’ known distribution (Lillehammer 1985, 1988; Zwick 1992), the identification should be checked.Published as part of Boumans, Louis, 2011, The Plecoptera Collection At The Natural History Museum In Oslo, pp. 280-290 in Illiesia 7 (25) on page 284, DOI: 10.5281/zenodo.475821
Capnia oklandi Morton 1923
No full textThe dry type collection of the NHM contains the imaginal syntypes of Capnia oklandi Morton 1923 from Novaya Zemlya (Morton 1923). Morton cites 4♀ no. 130, 3♀ no. 174, 1 nymph no. 175 and 1 nymph no. 178. The seven imagines are preserved, four of these labelled as ‘TYPE’. Two of the latter, and one of the specimens not labelled as type, lack the abdomen. Capnia oklandi is considered a junior synonym of C. zaicevi Klap {lek, 1914 (Zhiltzova 1964; Zhiltzova 1966).Published as part of Boumans, Louis, 2011, The Plecoptera Collection At The Natural History Museum In Oslo, pp. 280-290 in Illiesia 7 (25) on page 287, DOI: 10.5281/zenodo.475821

A.Lillehammer [labelled P1441: ethanol; slides with nymphal legs and cerci specimens numbered 2 and 5; with nymphal pronotum specimens no. 1-4]; Finnmark, Tana, Tjernet, bekk [stream], 3.vii.1968, 1 nymph, leg. A. Lillehammer [P1461: only slide with nymphal legs and cerci]; Finnmark, Kautokeino, Hannujokka, 26.vi. 1972, circa 50 imagos, leg. A.Lillehammer [P2693: ethanol; slides of the epiproct of three male specimens numbered 30-32]; Finnmark, Porsanger, Skoganvarre Ovrevatn, N 69.84390° E 25.07600°, 1♂, leg. L. Boumans, T. Ekrem & S. Roth, det. L. Boumans, col. NHM barcoding tissue collection EPT- 637. Nemoura sahlbergi is a Palaearctic, and possibly circumpolar species (Teslenko & Bazova 2009). It occurs in the northernmost parts of Fennoscandia and is common in the province of Finnmark (Lillehammer 1985; 1988:118). Lillehammer probably used this material for his description of the nymph (Lillehammer 1972b). Figure 2 shows one of the epiprocts in the slide collection.Published as part of Boumans, Louis, 2011, The Plecoptera Collection At The Natural History Museum In Oslo, pp. 280-290 in Illiesia 7 (25) on page 286, DOI: 10.5281/zenodo.475821
Perlodes dispar
No full textPerlodes dispar (Rambur 1842) Oslo, Sørkedalselva, Langlielva, 25.ii.1969, 1 nymph, leg. Smestad [slide marked P1669 with nymphal cercus, leg and maxilla+; Akershus, Søndre Høland, 1♂ [slide with no further labelling, bearing male subanal lobe and cerci; the municipality Søndre Høland existed between 1924 and 1966+. This species is widely distributed and common in Europe (Zwick 2004). The north-western border of its distribution lies in south-eastern Norway, where it occurs in shallow streams with a high summer temperature (Lillehammer 1988:67). There are relatively many observations of this species in southwestern Sweden (Swedish biodiversity information portal artportalen.se, last accessed 25 August 2011). The NHM contains no complete specimens. Artskart includes two collection-based records from the province of Troms. As these collection sites are far from the known distribution of this species (Lillehammer 1985, 1988), the identification of these specimens should be checked.Published as part of Boumans, Louis, 2011, The Plecoptera Collection At The Natural History Museum In Oslo, pp. 280-290 in Illiesia 7 (25) on page 284, DOI: 10.5281/zenodo.475821
Nemoura viki Lillehammer 1972
No full textNemoura viki Lillehammer 1972 Finnmark, Kautokeino, Emmatjernbekken, 29.vi.1972, 55 imagos, leg. A. Lillehammer [labelled P2694: ethanol, specimens stored individually in numbered vials, together with their detached right forewing; slide-mounted epiprocts specimens no. 49-52]; slidemounted epiproct of an additional, unlabelled specimen. Only records from northernmost parts of Finland and Norway were known to Lillehammer (1988:118). Later, Johansson and Nilsson (1989, 1994) reported isolated finds of N. viki from the Swedish province of Västerbotten, 500 km south of the previously reported distribution. The Artskart database includes two collection-based records from the province of Troms in northern Norway. In all, there are very few records of this taxon. By all likelihood all specimens at the NHM have been identified by Lillehammer, but this is not documented. One of the slide-mounted epiprocts is shown in Fig. 3. The type specimens of N. viki appear to be missing (see below). The specimens used for the description of the nymphs (Lillehammer 1986) have not been located either.Published as part of Boumans, Louis, 2011, The Plecoptera Collection At The Natural History Museum In Oslo, pp. 280-290 in Illiesia 7 (25) on page 286, DOI: 10.5281/zenodo.475821
Amphinemura palmeni Koponen 1916
No full textAmphinemura palmeni Koponen 1916 The NHM contains no ethanol-preserved or slidemounted specimens labelled as such, nor do Lillehammer’s publications bear evidence that he studied specimens of A. palmeni. The online data portals do not contain any observations either. Very few findings of this species have ever been reported. The absence of specimens and observations of this red-listed taxon is due to the uncertainty of its taxonomic status. Koponen (1917) described Amphinemura palmeni from the Kola Peninsula in northwest Russia. Brinck (1949:19) considered the name to be a synonym of A. standfussi (Ris 1902), ‚considering the description and the type material'. Then Tobias (1973) described A. norvegica from northern Norway. Meinander (1975) reports that Tobias and Baumann later checked the type of A. palmeni and found out that both A. norvegica and the Nearctic A. linda (Ricker 1952) were conspecific with A. palmeni. Illies’s catalogue (1966:185) reproduces Brinck’s opinion, while his chapter in Limnofauna Europaea (Illies 1978) later follows Meinander. Lillehammer’s (1988) identification key and handbook lists A. palmeni as a valid species and A. norvegica Tobias 1973 as its junior synonym. I am currently re-examining the taxonomic status of this species. Preliminary analyses of mitochondrial sequences from P. cf. palmeni from Finnmark and Troms provinces in Norway and bordering Finland (northern Lapland province) show that two distinct clades of standfussi -like stoneflies occur in northern Scandinavia. Further research should establish whether these clades can be considered as easterly forms of A. standfussi, and whether the different clades interbreed.Published as part of Boumans, Louis, 2011, The Plecoptera Collection At The Natural History Museum In Oslo, pp. 280-290 in Illiesia 7 (25) on pages 285-286, DOI: 10.5281/zenodo.475821
Xanthoperla apicalis
No full textXanthoperla apicalis (Newman 1836) Buskerud [Ringerike] viii.[18]45, 2♀, leg. J.H. Siebke, det. R. Brekke [two specimens on two pins, additional labels ‘ Siebke’, ‘33’, ‘ Gf 2276 ZM Oslo’, respectively ‘34’ and ‘ Gf 2277 ZM Oslo’ +; * Hedmark + Elverum, [no date], 2♀, leg. J.H. Siebke, det. R. Brekke [two specimens on a single pin, additional labels ‘ Siebke’, ‘35-36’ and ‘ Gf 2278 ZM Oslo’ +; Nord- Trondelag: Steinkjer, Ogna, 1 imago sex?, 22.vii.1967, leg.? [ethanol specimen, genitalia removed and lost]; Grong, Fjerdingelven, 1 male, 2.vii.1970, leg. A. Lillehammer [ethanol specimen, genitalia slidemounted, labelled P2137]. Xanthoperla apicalis is a species of larger rivers in Europe (Lillehammer 1988:80). It was historically widespread in Europe but suffered from habitat fragmentation and has become very rare in central Europe (Zwick 1992, 2004; Koese 2008:105). It is also rare in Norway, with a scattered and little known distribution. The nineteenth century specimens in the NHM are listed by Brekke (1941) under the name Chloroperla borealis Bengtsson, 1933. According to Brekke, Schøyen (1887) refers to these same specimens under the name Isopteryx apicalis Newm. Schøyen does not cite specimens explicitly, but lists the municipalities Christiania (= Oslo), Ringerike and Elverum. Brittain (1983; Brittain et al. 1984) discusses finds from the Namsen and Sanddøla rivers in Nord Trondelag, as well as the river Glomma in Hedmark. Note: Zwick (2004) remarks that figure 114 in Lillehammer (1988:76) does not show the pronotum of X. apicalis. The NHM slide collection includes three slides marked ‘P39 X. apicalis’, bearing a nymphal hind leg, cerci, two heads, one pronotum and a complete small nymph. The incomplete collecting event data associated with P39 is ‘Storelva, 26.iv.1966 ’. The pronota in these slides do not look like Lillehammer’s fig. 114. However, they are probably Siphonoperla (Peter Zwick, personal communication September 2011).Published as part of Boumans, Louis, 2011, The Plecoptera Collection At The Natural History Museum In Oslo, pp. 280-290 in Illiesia 7 (25) on page 284, DOI: 10.5281/zenodo.475821
