Linnaeus's butterflies (Lepidoptera: Papilionoidea and Hesperioidea)

The names of all the species of butterflies described by Linnaeus under "Papilio" are researched. Of the 305 names treated, 243 (c. 80%) are currently valid as specific (241) or subspecific (2), 29 are junior synonyms, 14 are invalid (one of these applying to a fake), and for 13 the identity is unknown or uncertain. Six species of moths misidentified by Linnaeus as butterflies are cited in the study, but details are not included. One hundred and fifty-two lectotypes have been designated, representing about 56% of the sum of the valid names and junior synonyms. Of these, 99 were selected from specimens in the Linnean Society of London, 52 from Queen Ludovica Ulrica's collection, Uppsala, and one lectotype is a Petiver specimen from the collection of Sir Hans Sloane. Linnaeus described at least five species, possibly eight, from the literature alone. All Linnaean material examined is documented, as are 'subsequent' specimens that are associated with Linnaean material. Synonymy and homonymy are discussed and presented, as are the identities of type localities. Care has been taken to achieve a practical balance between Linnaean and current species identities. Linnaean material studied included specimens from The Linnean Society of London, Museum Ludovicae Ulricae (Uppsala University), the Clerck and De Geer collections in the Naturhistoriska Riksmuseet, Stockholm, and the collection of James Petiver, now part of the collection of Sir Hans Sloane housed in The Natural History Museum, London.     

The species of Hymenoptera described by Linnaeus in the genera Sphex, Chrysis, Vespa, Apis and Mutilla

Data are presented on the type-material representing the species described by Linnaeus in his genera Sphex, Chrysis, Vespa, Apis and Mutilla , The names here considered total 158; six are currently applied in the Hymenoptera Parasitica. Of the balance of 147, three are emendations and five are unavailable homonyms or names proposed in the synonymy of other species. Fifteen Linnaean names are here placed as synonyms. One name is attributed to an author other than Linnaeus, and live names remain species incertae sedis. The remainder, 118, are applied as valid names in die Hymenoptera Aculeata. Holotype specimens in London, Uppsala or Stockholm represent 60 names; 55 names are based on lectotype specimens of which 49 are here designated, two by other authors. One name is represented by a neotype specimen in Lund, and one by a lectotype figure. One non-aculeate species is based on syntypes. Specimens appear to be lost with respect to 25 names; three specimens in Uppsala may be the holotypes of a further three species.
Eight new combinations are made, and twelve new synonyms established; three further new combinations and three further new synonymies are suggested. A systematically arranged summary of species treated and of nomenclatural changes made is given. Nomenclatural changes affecting non-Linnaean names are included where relevant; lectotypes are designated for two non-Linnaean species.     

Lectotypification of Linnaean names for Flora Nordica (Brassicaceae - Apiaceae)

Linnaean names appearing in Flora Nordica in the families Brassicaceae - Apiaceae (in the conventional family sequence of the Flora) are typified. The main sources for types are the Linnaean Herbarium (LINN), the Clifford Herbarium (BM), the Burser Herbarium (UPS) and the Iter lapponicum herbarium in Paris (LAPP), and cited illustrations. The study forms part of the "Linnaean Plant Name Typification Project" based at The Natural History Museum, London (BM). - Flora Nordica notes No. 31.     

Typification of the name Thymus serpyllum L. (Lamiaceae)

Lectotypification of the name Thymus serpyllum L. (Lamiaceae) is presented. The name is typified by a specimen from the Burser herbarium (UPS), the only one which corresponds well with the present concept of T serpyllum and undoubtedly represents original material.     

The typification of Lolium perenne L. and Loliutn temulentum L. (Poaceae)

LOOS, B. P. & JARVIS, C. E., 1992. The typification of Lolium perenne and Lolium temulentum (Poaceae). The typification of the Linnaean species Lolium perenne and Lolium temulentum has been studied. Lolium perenne is typified by material in LINN, as proposed by Terrell, but it has been necessary to select a lectotype for L. temulentum , and material in the Burser herbarium (UPS) has been chosen for this purpose. The study shows that although Linnaeus used awns as a diagnostic character to distinguish the two species, he was aware of the intraspecific variability in this character.     

The genus Maesa (Maesaceae) in the Philippines

A comprehensive taxonomic revision of the genus Maesa Forssk. (Maesaceae) occurring in the Philippines is presented for the first time. Thirteen species are recognized, including a newly described species, M. stonei , which is most similar to M. reflexa . Several previously used names are reduced to synonymy, including M. pachyphylla and M. undulata (both reduced to synonymy with M. cumingii ), and M. elmeri , M. laxa and M. ramosii (all reduced to synonymy with M. indica ). Extensive lectotypification has been necessary due to the destruction of many type specimens, particularly those of C. Mez (in B) and E. D. Merrill (in PNH). The conservation status of each species is determined using the IUCN red list categories and criteria.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 145 , 17–43.     

A taxonomic revision of Encyclia (Orchidaceae: Laeliinae) in Costa Rica

A taxonomic revision of Encyclia (Orchidaceae) in Costa Rica is presented. The taxonomic history of the genus and its phylogenetic position are discussed. Characters of vegetative and floral morphology are described and their taxonomic significance is discussed. The genus is treated as comprising nine species in the country and a key to species is provided. Each taxon is described on the basis of Costa Rican material, illustrated in a composite plate, and its distribution within the country is assessed. Distribution maps for all the taxa are given. Overall distribution, derivation of name, synonymy, notes on species ecology and diagnostic features are presented for each taxon. The names Encyclia tonduziana and Epidendrum mooreanum are typified. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 168 , 395–448.     

Taxonomic revision of the genus Succisella (Dipsacaceae) in the Iberian Peninsula

A revision of the three endemic Iberian species of Succisella G. Beck ( S. carvalhoana , S. microcephala and S. andreae-molinae ), based on herbarium studies, SEM photographs and field observations, is presented utilizing morphological, palynological, karyological, biogeographical and ecological characters. The distribution of the species in the Iberian Peninsula is shown in a grid map. Full synonymy is given for all taxa.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 144 , 351–364.     

The orthopteroid insects described by Linnaeus,with notes on the Linnaean collection

A list is given of the recently recurated Orthoptera s.l. held by the Linnean Society of London. The status of specimens in the collection is evaluated, eight lectotype designations are made, and the orthopteroid species described by Linnaeus are listed alphabetically.     

Lectotypifications of Lìnnaean names for Flora Nordica Vol. 1 (Lycopodiaceae — Papaveraceae)

Linnaean names appearing in Volume 1 of Flora Nordica are typified. The main sources for types are the Linnaean Herbarium (LINN), the Clifford Herbarium (BM), the Burser Herbarium (UPS) the Iter lapponicum Herbarium in Paris (LAPP), and cited illustrations. The study forms part of the "Linnaean Plant Name Typification Project" based at the Natural History Museum (BM). Flora Nordica notes no. 10.     

The Linnaean fish collection in the Linnean Society of London

Linnaeus's personal collection of fishes was part of the material purchased by J. E. Smith in 1783–1784 from Linnaeus's widow and which became the property of the Linnean Society of London in 1828. There are extant 168 dried specimens of fishes, mostly skins mounted on paper in the manner of herbarium specimens. The spirit-preserved material which belonged to Linnaeus was never sent from Sweden.
The history of the collection is recounted, and the sources of the specimens discussed. A catalogue of the collection is presented with discussion of the type status of the specimens and the sources for the typification of each taxon.     

The Noctuoidea (Lepidoptera) described by Linnaeus

Linnaeus described 166 nominal species of Noctuoidea, of which 144 (86.7%) are currently used as valid names, 18 are synonyms, one is a homonym and three taxa remain unknown. Seven taxa were described solely from illustrations in contemporary literature. Lectotypes are designated for 139 (87.4%) of the 159 remaining taxa, 122 of them from the Linnaean collection in London, 13 from the Queen Ludovica Ulrica's collection in Uppsala, Sweden, and four from other contemporary collections. Two Linnaean senior synonyms are introduced: Hada plebeja comb. nov. (Linnaeus, 1761) for the current H. nana (Hufnagel, 1766) and Oeonistis altica (Linnaeus, 1768) comb. nov. for Oe. entella (Cramer, 1779). Erebus occiduus (Linnaeus, 1758) syn. nov. is a junior subjective synonym of E. crepuscularis (Linnaeus, 1758); L. marmorides (Cramer, 1775) Stat. rev. should be reinstated for Letis occidua auct. In two species pairs the Linnaean names have been interpreted incorrectly. The lectotype designation of Phalaena prasinana Linnaeus, 1758, by Lempke (1947) is invalid because the specimen is not syntypic. According to the new lectotype, Pseudoips prasinanus (Linnaeus, 1758) comb. nov. replaces P. faganus (Fabricius, 1781), and Bena bicolorana (Fuessly, 1775) comb. nov. is available for the other species. Abrostola triplasia (Linnaeus, 1758) Stat. rev. replaces A. trigemina (Werneburg, 1864), and for the other species A. triparlila (Hufnagel, 1766) should be reinstated. One neotype designation [Eilema complanum (Linnaeus, 1758)], one lectotype designation [Xylena exsolela (Linnaeus, 1758)], and precedence of a junior synonym [Ophideres fullonia (Clerck, 1764)] over its unused senior synonym are to be referred to the ICZN; until their decision the current usage must be followed. The identity of Mesapamea secalis (Linnaeus, 1758) stat. rev. corresponds to current usage, but, under presence of syntypic material, the recent neotype designation by Lempke (1988) will be referred to the ICZN. The revision is mainly based on the discovery that the insect pins and the way specimens are prepared give evidence of the authenticity of the material. Contrary to the views of earlier authors, Linnaeus had his labels with the specific name pinned against the bottom of the drawers by the specimen pin. Because the labels have been moved twice during subsequent curations, their present position is less indicative of the authenticity than has been previously suggested. The origin of the so-called n-labels is discussed.     

A taxonomic revision of Paradoris sea slugs (Mollusca, Gastropoda, Nudibranchia, Doridina)

Paradoris , traditionally a generic taxon of discodorid sea slugs, is revised for the first time. One hundred and thirty specimens were examined, including all types and most of the nontype specimens available. New records for Paradoris are provided: South Africa, Tanzania, Seychelles, Western Australia, Thailand, Philippines, shallow waters of New Caledonia, southern Japan, and Hawaii. The individual variation of all taxonomic characters is thoroughly evaluated. Prior to the present study, Paradoris included 15 nominal species: 12 valid names and three synonyms. Three additional names, Discodoris erythraeensis , D. lora , and D. cavernae , are re-allocated to Paradoris , based on phylogenetic analysis. A phylogenetic diagnosis is provided for Paradoris : in particular, two new synapomorphies are described. Eight species names are regarded as valid: P. araneosa , P. dubia , P. erythraeensis , P. indecora , P. liturata , P. lopezi , P. mulciber , and P. tsurugensis . However, most of these species are poorly known, i.e. from very few specimens, and their taxonomic status might change when more individuals are available. P. lora is regarded as a nomen dubium . Six new synonymies are proposed, and explained by the fact that: (1) species names were created for one or a few specimens, without considering individual variation; (2) authors have not worked within a phylogenetic framework and have created new species names without considering all the existing species names already available within Paradoris . Three new morphospecies are described, but not formally named because their taxonomic status is still uncertain for several reasons (e.g. lack of knowledge of individual variation for some critical features).  © 2006 The Linnean Society of London, Zoological Journal of the Linnean Society , 2006, 147 , 125–238.     

Systematic revision of Myristicaceae (Magnoliales) in Madagascar, with four new species of Mauloutchia

The systematics of Malagasy Myristicaceae is revised to take into account new collections made since the work by Capuron in the 1970s, as well as improved knowledge from fieldwork and two scanning electron microscopy studies by the author. Four new species are described: Mauloutchia annickiae Sauquet, M. capuronii Sauquet, M. echinocarpa Capuron ex Sauquet, and M. sambiranensis (Capuron) Sauquet. In addition, basic information is given for each remaining Malagasy species of the family (synonymy, type specimen, updated distribution and main distinctive features). According to this treatment, Malagasy Myristicaceae now consist of four endemic genera and 15 species: Brochoneura Warb. (three species), Doyleanthus Sauquet (one species), Haematodendron Capuron (one species) and Mauloutchia (Baill.) Warb. (ten species). Two identification keys to these species are provided: one based primarily on fruit characters and one based primarily on male flower and inflorescence characters. Putative phylogenetic relationships among these species are also indicated, based on a previous combined morphological and molecular study by the author.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 351–368.
