Primary Type

The Egyptian fauna of the genus Nemestrinus Latreille, 1802 is revised. In 1967, Steyskal and El-Bialy listed 12 species from the region, but only six species are now recognized. The primary type specimens of the species N. aegyptiacus (Wiedemann, 1828), N. rufipes (Olivier, 1810), and N. lateralis Wiedemann, 1828 (N. lateralis being a synonym of N. rufipes) deposited in the Museum für Naturkunde, Berlin, Germany were examined. Two species (N. abdominalis Olivier, 1811 and N. fascifrons (Bigot, 1888) are placed as new synonyms of N. ater (Olivier, 1811), and N. ruficornis Macquart, 1840 is synonymized with N. rufipes (Olivier, 1811). Nemestrinus jullieni (Efflatoun, 1925) is confirmed as a synonym of N. aegyptiacus. Furthermore, three species (N. caucasicus Fischer, 1806, N. pallipes (Olivier, 1811), and N. persicus Lichtwardt, 1909) have been removed and are doubtful records from Egypt. A key to the species, lists of specimens examined, and Illustrations and distributions for each species are provided. The status of species of doubtful occurrence in Egypt is discussed.

Etheophanus Broun is considered a molytine based on the form of the pharyngeal plate, presence of a small spiculum relictum in the male, and presence of a pair of small internal apodemes on the antero-lateral corners of the 5th abdominal ventrite of the female. Examination of primary type specimens and newer material confirm one new species Etheophanus kuscheli sp. n. and two synonomies (Etheophanus nitidellus Broun, 1923 [= Etheophanus obscurus Broun, 1923] and Etheophanus striatus Broun, 1910 [=Etheophanus punctiventris Broun, 1914]). Generic and species diagnoses, a key to the species, and lectotype designations for three species are included. Phylogenetic reconstructions based on a combined analysis of the nuclear 28S rRNA and mitochondrial cytochrome c oxidase subunit I genes confirmed the status of E. kuscheli and a species complex, the E. nitidellus/E. optandus clade distributed in the southern portion of the South Island. The relationship E. pinguis [northern North Island] (E. striatus [southern North Island, northern South Island] (E. kuscheli [northwestern South Island] (E. nitidellus, E. optandus [southwestern North Island]) corresponds to geographic patterns found in other beetle lineages. Etheophanus striatus is composed of three lineages, one widespread in the north and south islands and two allopatric populations in the northwest South Island. The E. nitidellus/E. optandus complex includes four distinct lineages, one restricted to Fiordland, the other three sympatric in the region affected by the Haast Corridor.

One hundred sixty eight taxa of the genus Agrilus (Coleoptera, Buprestidae) mostly from the Palearctic and Oriental regions are studied and their taxonomic, nomenclatural, distributional or biological data are updated. The following new taxonomic or nomenclatural acts are proposed. The status of four taxa is changed: Agrilus grandiceps hemiphanes Marseul, 1866 is changed from subspecies to species Agrilus hemiphanes stat. nov.; Agrilus lopatini Alexeev, 1964 is changed from species to subspecies Agrilus araxenus lopatini stat. nov.; the specific name hermineus Abeille de Perrin, 1907 is removed from the synonymy of A. lineola as a name of subspecies Agrilus lineola hermineus revalidated name, stat. nov.; Agrilus validiusculus Semenov, 1891 is changed from species to subspecies Agrilus transversesulcatus validiusculus stat. nov.. The following fifteen new synonyms are proposed: grusinus Obenberger, 1917 syn. nov. (synonym of A. transversesulcatus Reitter, 1890); hassani Théry, 1930 syn. nov. (synonym of A. proteus Abeille de Perrin, 1893); ieiunulus Obenberger, 1936 syn. nov. (synonym of A. transversesulcatus validiusculus Semenov, 1891); italicus Obenberger, 1920 syn. nov. (synonym of A. cyanescens Ratzeburg, 1837); juxtasuturalis Abeille de Perrin, 1897 syn. nov. (synonym of A. transversesulcatus Reitter, 1890); niveosignatus Obenberger, 1914 syn. nov. (synonym of A. transversesulcatus validiusculus Semenov, 1891); panchlorus Abeille de Perrin, 1897 syn. nov. (synonym of A. curtulus Mulsant & Rey, 1863); perparvus Obenberger, 1918 syn. nov. (synonym of A. roscidus Kiesenwetter, 1857); philippovi Alexeev, 1965 syn. nov. (synonym of A. vaginalis Abeille de Perrin, 1897); populneus Schaefer, 1946 syn. nov. (synonym of A. suvorovi Obenberger, 1935); rosei Niehuis & Bernhard, 2005 syn. nov. (synonym of A. viridis Linné, 1758); shamyl Obenberger, 1922 syn. nov. (synonym of A. lineola hermineus Abeille de Perrin, 1907); suturisignatus Obenberger, 1924 syn. nov. (synonym of A. transversesulcatus Reitter, 1890); tetrastichus Obenberger, 1924 syn. nov. (synonym of A. fissifrons Fairmaire, 1849) and tifliscus Obenberger, 1936 syn. nov. (synonym of A. transversesulcatus Reitter, 1890). Agrilus grandiceps Kiesenwetter, 1857 is a dubious name of unknown taxonomic concept due to lack of the primary type. The following twenty-seven lectotypes of nominal taxa are designated: A. affectans Obenberger, 1923; A. alacris Kerremans, 1896; A. fidjiensis Obenberger, 1924; A. grusinus Obenberger, 1917; A. hassani Théry, 1930; A. hermineus Abeille de Perrin, 1907; A. hypericicola Abeille de Perrin, 1893; A. ieiunulus Obenberger, 1936; A. limoniastri Bedel, 1886; A. mephistopheles Abeille de Perrin, 1897; A. morio Kerremans, 1895; A. beauprei mourguesi Schaefer, 1954; A. nigrivestis Abeille de Perrin, 1897; A. niveosignatus Obenberger, 1914; A. panchlorus Abeille de Perrin, 1897; A. perparvus Obenberger, 1918; A. proteus Abeille de Perrin, 1893; A. roscidus Kiesenwetter, 1857; A. rumanicus Obenberger, 1924; A. shamyl Obenberger, 1922; A. subroscidus Obenberger, 1924; A. suturisignatus Obenberger, 1924; A. suvorovi Obenberger, 1935; A. fidjiensis tetrastichus Obenberger, 1924; A. tifliscus Obenberger, 1936; A. transversesulcatus Reitter, 1890 and A. validiusculus Semenov, 1891. Additionally, the geographical range or host plant data are updated or revised for many taxa. The North American Agrilus bilineatus (Weber, 1801) is recorded from a single record from Turkey which is the first introduction of a Nearctic Agrilus to the Palearctic fauna.

Resulting from the examination of the type specimens of the southern African bee species originally described in the genus Osmia, the taxonomic placement of 19 species is formally established. The following combinations are formalised: Osmia atrorufa Friese, 1913 to Wainia (Caposmia) atrorufa (Friese) comb. nov.; Osmia ausica Cockerell, 1944 to Hoplitis (Anthocopa) ausica (Cockerell) comb. nov.; Osmia capicola Friese, 1909 (replacement name for Osmia capensis Cameron, 1906) to Capicola capicola (Friese) comb. nov.; Osmia flavipes Friese, 1909 to Afranthidium (Nigranthidium) flavipes (Friese) comb. nov.; Osmia forficulina Cockerell, 1921 to Hoplitis (Anthocopa) forficulina (Cockerell) comb. nov.; Osmia karooensis Brauns, 1926 to Hoplitis (Anthocopa) karooensis (Brauns) comb. nov.; Osmia mediorufa Cockerell, 1932 to Hoplitis (Anthocopa) mediorufa (Cockerell) comb. nov.; Osmia namaquaensis Friese, 1913 to Hoplitis (Anthocopa) namaquaensis (Friese) comb. nov.; Osmia natalensis Cockerell, 1920 to Wainia (Caposmia) natalensis (Cockerell) comb. nov.; Osmia neavei Cockerell, 1936 to Hoplitis (Anthoc- opa) neavei (Cockerell) comb. nov.; Osmia ogilviae Cockerell, 1932 to Hoplitis (Anthocopa) ogilviae (Cockerell) comb. nov.; Osmia ornatula Cockerell, 1932 to Hoplitis (Anthocopa) ornatula (Cockerell) comb. nov.; Osmia orthodonta Cokkerell, 1932 to Hoplitis (Anthocopa) orthodonta (Cockerell) comb. nov.; Osmia pachyceps Friese, 1922 to Othinosmia (Megaloheriades) pachyceps (Friese) comb. nov.; Osmia piliventris Friese, 1913 to Hoplitis (Anthocopa) piliventris (Friese) comb. nov.; Osmia reginae Cockerell, 1932 to Hoplitis (Anthocopa) reginae (Cockerell) comb. nov.; Osmia rhodognatha Cockerell, 1932 to Hoplitis (Anthocopa) rhodognatha (Cockerell) comb. nov.; Osmia similis Friese, 1909 to Hoplitis (Anthocopa) similis (Friese) comb. nov.; Osmia turneri Cockerell, 1937 to Hoplitis (Anthocopa) turneri (Cockerell) comb. nov. The following new synonyms are established: Hoplitis (Anthocopa) namaquaensis (Friese) = Osmia ausica Cockerell syn. nov.; Capicola capicola (Friese) (replacement name for Osmia capensis Cameron) = Capicola braunsiana Friese, 1911 syn. nov., Capicola aurescens Cockerell, 1932 syn. nov., Hesperapis turneri Cockerell, 1934 syn. nov., Hesperapis obscura Cockerell, 1934 syn. nov.; Unlike the statement in Michener (2000: 403) Osmia? capensis Cameron, 1905 is probably not a synonym of Capicola braunsiana Friese given its body length. The type seems to be lost and the identity of this species remains unclear. Hoplitis (Anthocopa) similis (Friese) = Osmia forficulina Cockerell syn. nov; Wainia (Wainiella) sakaniensis (Cockerell, 1936) = Heriades albobarbatus Cockerell, 1937 syn. nov., Heriades debilicornis Cockerell, 1940 syn. nov., Heriades perpolitus Cockerell, 1947 syn. nov., Heriades otaviensis Cockerell, 1947 syn. nov. The status of Wainia (Caposmia) elizabethae (Friese, 1909) spec. rev. as a valid species is restored. Hoplitis (Anthocopa) conchophila Kuhlmann spec. nov., Wainia (Caposmia) gessorum Kuhlmann spec. nov. and the male of Wainia (Caposmia) atrorufa (Friese) are described for the first time. A checklist and an illustrated key to the seven southern African species of Wainia is provided. Notes on known flower visiting and nesting of Hoplitis (Anthocopa) and Wainia are given under the relevant species.

Abstract—Hymenophyllum subg. Mecodium, composed of the taxonomically notorious H. polyanthos and approximately 15 other closely related taxa, is a common element of filmy fern communities in the tropical and subtropical moist forests. In Taiwan, although only H. polyanthos and one or two closely related taxa were recognized in recent studies, considerable morphological variation has been observed among populations throughout the island. Thus, we conducted an extensive morphological investigation, as well as a molecular phylogenetic analysis, to clarify the specific diversity and phylogenetic relationships within Hymenophyllum subg. Mecodium in Taiwan. Field and herbaria surveys helped in recognizing five morphs in Taiwan, mainly differentiated by the combination of certain traits, viz., the presence or absence of stipe wings, general frond size and shape, degree of laminar crispation, sori position, and involucre shape. The different morphs had diverse ecological preferences. The phylogenetic tree, inferred from the sequences of the plastid loci rbcL and rps4-trnS, demonstrated that Hymenophyllum subg. Mecodium materials in Taiwan comprise several well-supported lineages, mostly corresponding to the classification based on morphology. Comparing with the protologues and type specimens of 34 related scientific names, the five morphs are herein recognized as five independent species. A new species, Hymenophyllum exquisitum, is described here. Also, the status of H. paniculiflorum is reconfirmed and that of H. fujisanense, H. parallelocarpum, and H. punctisorum reinstated. Only H. exquisitum and H. parallelocarpum are endemic to Taiwan among all the species studied. In addition, the names Hymenophyllum blumeanum, H. integrum, H. microsorum, H. polyanthos, H. tenellum, and H. wrightii are now excluded from the regional flora, and several related taxa from China, Taiwan, and the Philippines are treated as synonyms. This study unravels the deep phylogenetic relationships within Hymenophyllum subg. Mecodium in Taiwan and Eastern Asia.

Abstract The collection which belonged to the Prof. Ioan Nemeș (1924-2009), currently curated at the Museum of Natural Sciences Dorohoi (Botoșani County), is one of the most important and valuable collections of Lepidoptera preserved in a Romanian museum. Within this collection, a number of 47 type specimens have been identified, on which the descriptions of 28 species and other infraspecific taxa from 5 Lepidoptera families: Nepticulidae, Coleophoridae, Tortricidae, Crambidae and Geometridae have been based. All these specimens were collected from the territory of Romania. Some of the identified type specimens belong to taxa with doubtful status, whose original descriptions are poor and superficial. The discovery of these type specimens finally allowed assessing the status of several taxa, and the following new synonymies are proposed: Ancylis uncella (Denis & Schiffermüller, 1933) = Ancylis bucovinella Peiu & Nemeş, 1969 nov. syn.; Epiblema foenella (Linnaeus, 1758) = Epiblema foenella f. fracta Popescu-Gorj & Nemeş, 1965 nov. syn.; Pelochrista decolorana ( Freyer, 1842) = Pseudeucosma alexinschiana Peiu & Nemeş, 1968 nov. syn.; Nascia cilialis ( Hübner, 1 796) = Calamotropha olarui Nemeş, 1972 nov. syn.; Scopula (Calothysanis) subpunctaria (Herrich-Schäffer, 1847) = Scopula peiui Olaru, 1973 nov. syn.; Idaea pallidata (Denis & Schiffermüller, 1775) = Sterrha constantineanui Olaru, 1973 nov. syn.; Idaea elongaria (Rambur, 1833) = Sterrha nemesi Olaru, 1973 nov. syn.

The Status

The taxonomic status and positions of taxa described within the genus Kreizbergius Korshunov, 1990 (the simo-group sensu Ackery, 1975) are rearranged. Lectotypes of the following taxa are designated: Parnassius simo var. simonius Staudinger, 1889, Parnassius simo var. simulator Staudinger, 1889, Parnassius gylippos Fruhstorfer, 1903, Parnassius simo confusa Bang-Haas, 1927. It is shown that K. anrdeji (Eisner, 1930) is a subspecies of K. simonius and has the oldest available name K. simonius kozlovi Avinov, 1913. New synonyms within K. simo and K. simonius are established.

Nearly a century ago, wing venation was introduced in gracillariid taxonomy as a means to diagnose closely related genera and species groups. Recent advances in non-destructive virtual micro-dissections suggest promising approaches with which to revisit the relevance of wing venation characters on historic primary type specimens. Many unique type specimens in Gracillariidae and other microlepidoptera groups preserved in museum collections are in poor condition, and over the course of history have suffered loss or damage to their abdomens. Consequently, genitalia morphology is not available for diagnoses and comparisons. In this paper we emphasize the need to include the type species and type specimens into the broader context of taxonomic studies on micro-moths in general and the family Gracillariidae in particular. The genus Caloptilia has a world-wide distribution and has been the subject of research for more than 200 years, yet the generic boundaries and groupings within the genus are still unresolved due to the lack of a reliable set of taxonomic characters obtained from the primary types. We describe a method of virtual descaling of the fore- and hindwings using the unset micro-moth type specimen of Caloptilia stigmatella Fabricius, 1781, in order to demonstrate that the study of historic and fragile type specimens and diagnoses of their internal morphological characters becomes possible by applying new and non-destructive technology.

Holotypes of 19 species and non-type specimens preserved in the Sasa collection at The National Museum of Science, Tokyo, Japan, have been examined. Seventeen new synonyms are given, as follows: Paratrissocladius ogasaduodecimus Sasa et Suzuki, 1997 = Paraphaenocladius impensus (Walker, 1856); Bryophaenocladius togafelix Sasa et Okazawa, 1992, and B. toganitemus Sasa et Okazawa, 1992 = Pseudorthocladius togakileus Sasa et Okazawa, 1992; Bryophaenocladius togatenuis Sasa et Okazawa, 1992 of Smittia nudipennis (Goetghebuer, 1913); Chironomus daitoefeus Sasa et Suzuki, 2001 of C. circumdatus Kieffer, 1916; C. inaabeus Sasa, Kitami et Suzuki, 2001 = C. nippodorsalis Sasa, 1979; C. tokarabeceus Sasa et Suzuki, 1995 = C. okinawanus Hasegawa et Sasa, 1987; C. ginzanbeceus Sasa et Suzuki, 2001 = C. riparius Meigen, 1904; C. simantobeceus Sasa , Suzuki et Sakai, 1998 = C. claggi Tokunaga, 1964; C. echizensis Sasa, 1994 = C. yoshimatsui Martin et Sublette, 1972; Chironomus famiabeus Sasa, 1996, C. inabeceus Sasa, Kitami et Suzuki, 2001 and C. ginzanabeus Sasa et Suzuki, 2001 = Glyptotendipes biwasecundus Sasa et Kawai, 1987; Chironomus kagaensis Sasa, 1994 = Glyptotendipes tokunagai Sasa, 1979; Chironomus toyamabiceus Sasa, 1996 = Kiefferulus umbraticola Yamamoto, 1979; Microtendipes iriocedeus Sasa et Suzuki, 2000 of Polypedilum bingoparadoxum Kawai, Inoue et Imabayashi , 1998. The sufficient reason why Chironomus daitocedeus Sasa et Suzuki, 2001 should be treated as a junior synonym of C. javanus Kieffer, 1924 is shown. Two further species: Paratrissocladius sudagaicedeus Sasa et Tanaka, 2001 and Bryophaenocladius togatenellus Sasa et Okazawa, 1992 are transferred to Chaetocladius. Specimens from Okinawa, Miyako and Ishigaki Islands, originally reported as Rheocricotopus chalybeatus (Edwards, 1929) are identified as R. okifoveatus Sasa, 1990. A new species, Einfeldia sasai is described on the basis of specimens recorded from Minamidato Island, previously incorrectly determined as E. pagana.

Eleven Species

The collections of fungus gnats by Johan Wilhelm Zetterstedt (1785–1874), lodged in the Museum of Zoology in Lund, Sweden, are examined for all species belonging in the tribe Exechiini Edwards. The majority of the material was collected in Fennoscandia, mainly in Sweden, in the first half of the 19 th century. Altogether 37 species of the tribe Exechiini could be safely identified. Three additional species are strongly indicated to be present in the collections, but could not be identified with certainty, viz. Allodia (Brachycampta) alternans (Zetterstedt, 1838), Cordyla murina Winnertz, 1863 and Stigmatomeria crassicornis (Stannius, 1831). Some of Zetterstedt's types have been erroneously synonymized and misinterpreted in modern literature. Hence, illustrations of terminalia are presented for all recognizable Exechiini types described by Zetterstedt. In order to preserve nomenclatural stability a lectotype is selected for Brevicornu griseolum (Zetterstedt, 1852) sensu auctore nec Edwards, and a neotype is selected for Allodia (Brachycampta) alternans (Zetterstedt, 1838). Two species names are reinstated, viz. Brevicornu canescens (Zetterstedt, 1852) sp. restit. stat. n. and Notolopha brachycera (Zetterstedt, 1838) sp. restit. stat. n. Two new synonyms are established, viz. Notolopha brachycera (Zetterstedt, 1838) = Allodiopsis (Notol- opha) tuomikoskii Zaitzev & Maximova, 2000 syn. n., and Brevicornu griseolum (Zetterstedt,1852) = Brevicornu boreale (Lundström, 1914) syn. n. All type specimens of Brevicornu fusculum (Zetterstedt, 1838) have lost their abdomens. No material of Exechia parvula (Zetterstedt, 1852) or Cordyla canescens Zetterstedt, 1852 could be located in the collections. Although the type material of Exechia parvula probably is lost, the name is still valid as a junior synonym for Mycetophila nana Staeger, 1840 since Mycetophila nana Staeger, 1840 is a junior primary homonym of Mycetophila nana Macquart, 1826. Cordyla canescens has been made a junior synonym for Stigmatomeria crassicornis (Stannius, 1831). The identity of Brevicornu fusculum is highly uncertain and the name must remain as a nomen dubium. Eleven species are reinstated or correctly reported from Sweden for the first time: Allodia (Allodia) tuomikoskii Hackman, 1971, Allodia (Allodia) zaitzevi Kurina, 1998, Allodiopsis rustica (Edwards, 1941), Brevicornu canescens (Zetterstedt, 1852), Brevicornu nigrofuscum (Lundström, 1909), Exechiopsis (Xenexechia) crucigera (Lundström, 1909), Pseudexechia aurivernica Chandler, 1978, Notolopha brachycera (Zetterstedt, 1852) Synplasta gracilis (Winnertz, 1863), Tarnania dziedzickii (Edwards, 1941), and Tarnania nemoralis (Edwards, 1941).
