Type specimens and identity of the described species of Conus.

During the third decade of the 19th century, 21 authors described 35 Recent and 11 fossil species of Conus , in 26 separate publications. This brought to 532 the number of species-group names in the genus introduced up to 1830. Only five fossil and seven Recent species are now considered valid. Two additional valid Recent species were described but were given preoccupied names. The remaining nominal species are concluded to be junior or contemporaneous synonyms (19), nomina dubia (11), of infrasubspecific rank (1), or not now considered Conus (1). At present 160 valid species of Conus are recognized from the species-group names described between 1758 and 1830. Of these, 138 are extant and 22 are known only as Tertiary fossils. Nine otherwise valid species, six Recent and three fossil, were described but were given preoccupied names.     

Chronological analysis of the species of Conus described during the 18th century

The 339 species-group names in the gastropod genus Conus proposed between 1758 and 1800 have been analyzed in chronological order, in order to (1) identify each nominal species, and (2) determine the correct name of each valid species. Additions and corrections are given to the author's series of papers on type specimens and identity of the described species of Conus. A table listing the 339 species-group names alphabetically indicates the present locations of the 124 known type specimens and the status of each name. At present, 123 valid species are recognized (118 Recent, 5 Tertiary), 159 names are synonyms of previously or simultaneously described species, 35 are nomina dubia, 19 are assigned to infrasubspecific rank, and 3 have been trandferred to genera in other families. Problems involving homonymy of 44 names have been resolved. The proportion of valid species to described species remained quite constant (about 80%) between 1758 and 1786, but then declined sharply to 40%. By 1800, although only 13% of all known species-group names in Conus had been introduced, they probably account for 25% of the known valid Recent species. Extension of the chronological study to species described through 1840 may establish the correct names of half the valid Recent species of Conus.     

Type specimens and identity of the described species of Conus VII. The species described 1810–1820

During the second decade of the 19th century, eight authors described 24 recent and 26 fossil species of Conus , bringing to 486 the number of proposed species-group names in the genus through 1820. This study analyses these nominal species, as well as three described by Perry in 1810, and evaluates the status of each. Most of the European Tertiary species described by Brocchi in 1814 and some of those described by Borson and Schlotheim in 1820 are valid. Megerle von Mühlfeld in 1816 and Dillwyn in 1817 each described a valid recent species. All other Conus species names introduced during the period are synonyms of previously or contemporaneously described species or nomina dubia. Type specimens of 23 species, including one neotype, are known to exist today. At the present time 148 valid species of Conus are recognized from the species-group names introduced between 1758 and 1820. Of these, 131 are extant and 17 are known only as Tertiary fossils. In addition, six otherwise valid species, three recent and three fossil, were described but were given preoccupied names.     

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 type specimens and identity of the species described in the genus Lithobius by F. Meinert, and now preserved in the Zoological Museum, Copenhagen University (Chilopoda: Lithobiomorpha)

The 32 species described by Meinert in the genus Lithobius which are represented by type material in t h e Zoological Museum, Copenhagen University, are redescribed from that material. It is concluded that 17 of these species are valid, one is a subspecies of Lithobius forficants (L.) and 12 are junior synonyms: two are junior homonyms, but both are also synonyms of described species.     

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.     

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.     

The type specimens and identity of the Siberian species described in the genus Lithobius by Anton Stuxberg in 1876 (Chilopoda: Lithobiomorpha)

The nine Siberian species described by Stuxberg in the genus Lithobius are redescribed from the original material. It is concluded that six of these species (ostiacorum, princeps, sulcipes, nordenskioldii, fugax and vagabundus) are valid and that three (scrobiculatus, formicarum and captivus) are junior synonyms. Three further species, one of them new, have been found among Stuxberg's Siberian specimens and are described.     

The identity of the European and Mediterranean species of Lithobiidae (Chilopoda) described by K. W. Verhoeff and now represented by material preserved in the British Museum (Natural History)

The status of the 15 European and Mediterranean species and subspecies of Lithobiidae described by Verhoeff which are represented by material in the Verhoeff Collection of Myriapoda in the British Museum (Natural History) is evaluated. It is concluded that Lithobius fasciatus graecus is a junior synonym of Eupolybothrus litoralis (L. Koch), Polybothrus cerberus brentanus a junior synonym of Eupolybothrus tridentinus (Fanzago) and Lithobius pachypus a junior synonym of Hessebius barbipes (Porat); Lithobius corcyraeus and Lithobius forjicatus calamatanus are both junior synonyms of Lithobius viriatus Sseliwanoff; Lithobius pusillus var. parvus and Lithobius audax jaqueti are both junior synonyms of, and Lithobius borisi a subspecies of, Lithobius erythrocephalus C. L. Koch; Lithobius leostygis and Lithobius herzegowinensis are both valid species of Eupolybothrus Verhoeff; and Lithobius forjicatus parietum, Lithobius erythrocephalus cerberi, Lithobius acuminatus cassinensis and Lithobius trebinjanus are all valid species of Lithobius Leach. The status of Lithobius vosseleri is still undecided. The specimens of all but the well-known species are fully described and, where appropriate, lectotypes are selected.     

Type specimens of Mitridae (Mollusca:Gastropoda) described by Linnaeus in the genera Voluta, Buccinum and Bulla between 1758 and 1771

From the 16 species of Mitridae described by Linnaeus between the years 1758-71 11 species are considered valid and available for taxonomic use; four specific names have been suppressed by the International Commission on Zoological Nomenclature for taxonomic usage (1968). One specific name, i.e. Voluta mitra episcopalis Linnaeus, has appeared in various combinations in malacological literature over the years. From the style of listing in the 10th edition of the Systerna Naturae , it is evident that 'episcopalis' has to be treated as of infraspecific rank; there is no evidence that 'episcopalis' is even a valid subspecies of Voluta mitra.
Three holotypes and five lectotypes designated in this paper are extant in the Linnaean collection; illustrations representing three Linnaean species have been selected as lectotypes.     

The species of "Ichneumon" (Hymenoptera) described by Linnaeus

Ichneumonidae in the Linnaean and other collections have been critically assessed with regard to their status as type-specimens of species described by Linnaeus. The generic placements of the 56 nominal species of Ichneumonidae (54 originally in Ichneumon and two in Mutilla) described by Linnaeus are established after study of the extant type-material. Lectotypes are designated for eleven of the species and one new synonymy is established. Notes are given on the 33 species originally described by Linnaeus in Ichneumon but now placed in other families.     

Species of Proteocephalus Weinland, 1858 (Cestoda: Proteocephalidae) from cyprinid fishes in North America

A taxonomic study of Proteocephalus species parasitizing cyprinid fishes in North America, namely Proteocephalus ptychocheilus Faust, 1920 and Proteocephalus cobraeformis Haderlie, 1953, has demonstrated their conspecificity with Proteocephalus torulosus (Batsch, 1786), a common parasite of cypriniform fishes (Cyprinidae and Cobitidae) in the Palaearctic Region. Proteocephalus ptychocheilus and P. cobraeformis are considered junior synonyms of P. torulosus.

A partial systematic revision of the day geckos, Phelsuma Gray, of Madagascar (Reptilia: Squamata: Gekkonidae)

Recent survey work in Madagascar has led to significant changes in the systematics of Madagascan Phelsuma. A new species from the Masoala Peninsula in northeastern Madagascar is described, which has a nostril position typical of Phelsuma from Mauritius, Reunion and Rodriguez islands. Phelsuma breviceps was rediscovered in extreme southern Madagascar and is resurrected from the synonymy of P. mutabilis. Phelsuma breviceps has fragile skin, a probable predator escape mechanism, similar to the condition found in geckos of the genera Ailuronyx and Geckokpis. Three new synonyms are recognized. Phelsuma befotahensis and P. checki are junior synonyms of P. abbotti , and P. minuthi is a junior synonym of P. lineata. Twenty species of Phelsuma occur in Madagascar, of which 16 are endemic. A checklist and identification key are provided. Conservation problems of Phelsuma in the coastal regions of Madagascar are briefly discussed.     

New species of the Eastern Hemisphere genera Afroheriades and Noteriades (Hymenoptera, Megachilidae), with keys to species of the former

New species of the rarely encountered megachilid genera Afroheriades Peters from South Africa, Afroheriades hyalinussp. n., and Noteriades Cockerell from Myanmar and Thailand, Noteriades jenniferaesp. n. and Noteriades spinosussp. n., are described and illustrated. The species are described to make their names available for forthcoming publications on phylogenetic studies of the family Megachilidae. Taxonomic notes and a comparative diagnosis for each genus are presented. Afroheriades hennigi (Peters) and Afroheriades reicherti (Brauns) are new junior synonyms of Afroheriades dolichocephalus (Friese). A key to the known species of Afroheriades is provided.     

Revision of the type species of Sigalion, Thalenessa and Eusigalion (Polychaeta: Sigalionidae)

The type species of Sigalion Audouin & Milne Edwards, 1830 (5. mathildae), Thalenessa Baird, 1866 (S. edwardsi Kinberg, 1856) and Eusigalion Augener, 1918 (E. vazensis) are re-examined. Since they were first described all three genera have been variously misrepresented, but are currently distinguished by the presence (Thalenessa; syn. Eusigalion) or absence (Sigalion) of a median antenna. Material examined in the present study indicates that S. mathildae also possesses a median antenna. Thalenessa and Eusigalion are considered to be junior synonyms of Sigalion and the generic placings of all species attributed to these genera are investigated.
