Separate Species

From Ontario hardwoods and conifers, 234 collections were examined for Ceratocystis and associated stains and vectors. Most previously described species, including many type specimens, were also studied.Among morphological characters used to separate species of Ceratocystis, those of the ascospores are the most reliable and are stressed in this study. Three-dimensional examination of ascospores, particularly in species possessing spores with sheaths, is necessary to determine spore shape accurately. Four ascospore sheath types are recognized: uniform, hat-shaped, double-brimmed, and quadrangular.A preliminary survey indicates that the bark-beetles Ips pini (Say) and Orthotomicus caelatus (Eich.) may be principal vectors for several Ceratocystis spp. on Ontario conifers.Based mainly on ascospore characters, a key to 60 species of Ceratocystis is provided. The species C. galeiformis Bakshi, C. obscura (Davids.) Hunt, C. polonica (Siem.) Hunt, and C. serpens (Goid.) C. Moreau are excluded. It is proposed that C. ambrosia Bakshi, C. capillifera (Hedgc.) C. Moreau, C. pluriannulata (Hedgc.) C. Moreau, and C. schrenkiana (Hedge.) C. Moreau be considered synonyms of C. pilifera (Fr.) C. Moreau and that C. vesca Davids. be treated as a synonym of C. olivacea (Math.) Hunt. The following species, described since Hunt's key was published, are included: C. bicolor (Davids, and Wells) Davids., C. brevicollis Davids., C. brunnea Davids., C. brunneocrinita Wright and Cain, C. dryocoetidis Kendrick and Molnar, C. europhioides Wright and Cain, C. falcata Wright and Cain, C. huntii Robinson, C. megalobrunnea Davids, and Toole, C. nigra Davids., C. perfecta Davids., C. tremuloaurea Davids, and Hinds, C. truncicola (Davids.) Griffin comb. nov. Eleven new species are described in this paper.Descriptions, figures, and distribution data are provided for most of the 32 species of Ceratocystis encountered in Ontario. The following previously described species were collected: C. bicolor (Davids. and Wells) Davids., C. brunneocrinita Wright and Cain, C. coerulescens (Munch) Bakshi, C. europhioides Wright and Cain, C.fimbriata Ell. and Halst., C. huntii Robinson, C. ips (Rumb.)

Hunt, C. truncicola (Davids.) Griffin comb, nov., and C. ulmi (Buism.) C. Moreau.The following new species are described by the author: C. acericola, C. allantospora, C. angusticollis, C. capitata, C. crassivaginata, C. dolominuta, C. magnifica, C. ochracea, C. pallida, C. spinulosa, and C. stenospora.

We review species of Parodon Valenciennes, 1850 from the Magdalena, Cauca, Orinoco, Amazonas, Atrato and Caribbean-Guajira River basins of Colombia using meristic and morphological characters. We recognize eight valid species, five previously described: P. apolinari Myers, from the Orinoco River basin; P. buckleyi Boulenger and P. pongoensis (Allen) from the upper Amazon; P. caliensis Boulenger, from the upper Cauca River drainage; and P. suborbitalis Valenciennes, from Lake Maracaibo basin. Three new species are described: P. alfonsoi, from the lower Magdalena River drainage; P. magdalenensis, from the middle Magdalena and upper Cauca River drainages; and P. atratoensis, from the Atrato River basin. We redescribe Parodon suborbitalis using type specimens and topotypes, and designate lectotypes. A taxonomic key is included for identification of the species, as well as geographic distribution maps.

Morphological Differences

The subgenus Brygoomantis in the Madagascar-endemic genus Mantidactylus contains 12 nominal species but is in urgent need of taxonomic revision as many additional, genetically divergent but undescribed candidate species have been identified. We here take a first step towards a better resolution of this group by describing a new species, Mantidactylus schulzi sp. nov., occurring at the Tsaratanana and Manongarivo Massifs, differentiated in genetic, bioacoustic and sometimes morphological characters from its closest relatives. We show that upon detailed study, most species in Brygoomantis can be delimited by concordant differentiation of mitochondrial and nuclear DNA, and by bioacoustic and morphological differences. We flag this group of morphologically similar frogs as a test case where molecular data on historical type specimens by ancient DNA methods might be needed to reach a satisfying clarification of taxonomy and nomenclature. However, the status of the new species M. schulzi is not in doubt as it is morphologically distinct from most historical type specimens, and microendemic to a region in northern Madagascar from where no earlier names exist.

Two New Species

Two new species of the weevil genus Rhamphus from Italy are herein described: R. bavierai n. sp. (Sicily) and R. hampsicora n. sp. (Sardinia). Both are morphologically and from a molecular perspective close to R. oxyacanthae (Marsham, 1802) and R. monzinii Pesarini & Diotti, 2012. Aside from a diagnostic description and a synoptic key, distribution data and notes on the host plants of the four species are reported. Whereas R. monzinii can be distinguished by several morphological characters, the other three species are morphologically very similar to each other and separable only by the combination of a few subtle characters. On the contrary, a preliminary molecular study revealed substantial divergences of mtCOI from 6.2 to 14.9% between the species, confirming the importance of an integrative taxonomy.

The clover, or brown, mite, Bryobia praetiosa Koch, was described in 1836 from specimens collected an shrubbery in Germany. The systematics of the species is complex and confusing. By 1838, Koch had described four species in the genus Bryobia but he preserved no type specimens and his descriptions do not agree with his illustrations (7, 12). Subsequent workers either placed Koch's species in synonomy nor described new species. Two species, speciosa Koch and ribis Thomas, have created the most controversv. B. speciosa was accepted as valid by Koch, Berlese, Canestrini and Fanzago, ind Oudemans, but rejected by von Hanstein and Trägårdh (2, 12). The gooseberry mite, B. ribis, was recognized as a valid species by Thomas and von Hanstein but Oudemans and Trägårdh placed it in synonomy with B. praetiosa (12). Further confusion was caused by the descriptions of additional new species of Bryobia and by descriptions of immature stages of B. praetiosa (8). The following taxonomic characters used by early acarologists in describing species of Bryobia have since been considered too variable for distinguishing species: number of femoral and tarsal hairs on the foreleg, body size, concavity of dorsum, and size and shape of cephalothoracic plate (7, 8, 12). Consequently, taxonomists have been at a loss to interpret Koch's original descriptions and subsequent redescriptions became inevitable. Because of the lack of morphological distinctions the modern trend has been to group all previously proposed species into one valid species (7, 8). As a result, 20 synonyms are now recognized for B. praetiosa (8).

A New Species

Abstract We describe a new species of Crocidura (Soricidae) from Sulawesi Island, Indonesia, documenting its novelty with both genetic and morphological characters. The new species is widespread on the island, with vouchered records from nine general localities distributed among five of the island’s areas of endemism. Morphologically, the new species is readily distinguished from all other described Sulawesi Crocidura by its intermediate body size, gray pelage, and long, hairy tail. The new species was mainly captured in pitfalls placed in the ground, but we also obtained evidence that it readily climbs trees and may be scansorial in its locomotor habits. Populations of the new species sampled from across the island are closely related, separated by < 0.02 uncorrected mitochondrial p-distances. The new species is one member of an endemic radiation of shrews on Sulawesi now known to contain six valid species and several undescribed species, all within the genus Crocidura. Resolution of species limits and phylogenetic relationships in this radiation is hindered by habitat loss at type localities, historical designation of new species using very small sample sizes, and a lack of genetic data from type specimens. Kami mendeskripsikan spesies baru Crocidura (Soricidae) dari Pulau Sulawesi, Indonesia, sekaligus mendokumentasikan keunikan karakter secara genetik maupun morfologi dari spesies tersebut. Spesies baru ini tersebar luas di Pulau Sulawesi, diketahui berdasarkan spesimen yang berasal dari sembilan lokasi umum yang tersebar di lima kawasan endemik di pulau tersebut. Secara morfologi, spesies baru ini dapat dibedakan dari spesies Crocidura lainnya dari Sulawesi berdasarkan ukuran tubuh yang sedang, rambut tubuh berwarna abu-abu, dan ekor yang panjang dan berambut. Spesies baru ini sebagian besar diperoleh dari perangkap sumuran yang ditanam didalam tanah, selain itu kami juga mendapatkan bukti bahwa spesies ini mampu memanjat pohon dan kemungkinan memiliki perilaku sebagai pemanjat. Beberapa populasi spesies yang dikoleksi dari Sulawesi ini mempunyai kekerabatan yang dekat, hanya dipisahkan oleh jarak proporsi DNA mitokondria (tidak terkoreksi) sebesar < 0.02. Spesies baru ini merupakan salah satu anggota dari suatu kelompok radiasi endemik cecurut di Sulawesi yang sampai saat ini diketahui terdiri atas enam spesies yang valid, dan beberapa spesies yang belum dideskripsikan, semuanya termasuk didalam genus Crocidura. Kepastian dalam menetapkan batasan jarak antar spesies dan hubungan kekerabatan genetik dari radiasi kelompok cecurut di Sulawesi terkendala oleh kerusakan habitat pada lokasi spesimen tipe, sejarah penamaan spesies yang hanya berdasarkan sampel yang sedikit, dan keterbatasan data molekuler dari spesimen tipe.

Summary Bursaphelenchus acaloleptae n. sp. is described and figured based upon its morphological characters and molecular profiles. The new species belongs to the xylophilus-group of the genus and is typologically characterised by its secretory-excretory pore being located slightly posterior to the median bulb, weakly tapering, relatively broad and straight female tail with variously shaped terminus, and rounded male bursal flap with squared terminus. The new species is phylogenetically and biologically closest to B. luxuriosae. These cryptic species share the host (habitat) tree species, Aralia elata (Araliaceae), the same carrier insect species, Acalolepta luxuriosa (Cerambycidae), and a characteristic phoretic adult form. However, the new species is typologically distinguished from all other xylophilus-group species by the combination of the above-mentioned characters and molecular profiles (SSU and LSU molecular barcodes). Further, B. acaloleptae n. sp. can be distinguished from its closest relative, B. luxuriosae, by mating experiments, i.e., these two species did not produce a viable F1 generation in reciprocal crossings, thereby confirming separate species status using the biological species concept.

The Lecithoceridae of southern Africa are reviewed, based on material preserved in the Ditsong National Museum of Natural History, Pretoria, Republic of South Africa. A total of 22 species are recognized including three new species: Idiopteryx jansei sp. nov., Lecithocera minyodes sp. nov. and Protolychnis natalensis sp. nov. Isotypa Janse, 1954 syn. nov. is synonymized with Idiopteryx Walsingham, 1891 and Homaloxestis lophophora Janse, 1954 stat. rev. is raised to species rank, separating it from H. cholopis Meyrick, 1906. In addition, Lecithocera ochrometra Meyrick, 1933 is transferred to Torodora Meyrick, 1894 as T. ochrometra (Meyrick, 1933) comb. nov., Lecithocera officialis Meyrick, 1911 is excluded from Lecithocera Herrich-Schäffer, 1853, and Dragmatucha proaula (Meyrick, 1908) is newly reported from Kenya. It is revealed that the male genital figure for Homaloxestis cholopis (Meyrick, 1906) by Janse (1954) was erroneously illustrated, based on a different species which is probably undescribed. Another miss-placed figure of the genitalia by Janse (1954) was also found for Lecithocera aenicta Janse, 1954. Diagnosis, descriptions (only for the new species), depositories of types, and distribution data of all the known species are provided. Images of adults, male and/or female genitalia, and the venation of a few species are illustrated.

The species belonging to the subgenus Molopsis Schatzmayr, 1943 of genus Tapinopterus Schaum, 1858 are revised. Thestudy is based on 372 specimens and includes, for each taxon, diagnosis, description (only for the new species), references,new distributional records and illustrations. Morphological characters of the male and female genitalia are widely used todelimit the separate species, the significance of some non-gonapophyseal genital structures of the females for the system-atics of Molopsis is explicitly emphasized. For the first time, the male genitalia of T. molopiformis, T. molopinus, T. wie-demanni, and T. rebellis, including also newly described species, as well as female genitalia of Molopsis are described andillustrated. All available type material is listed and represented by habitus photographs.As a result, 9 monotypic species of Molopsis are recognized. Tapinopterus rebellis (Chaudoir, 1868) and T. rebelliskumanensis (Reitter, 1884), formerly assigned to Molopsis are recognized as outgroup-taxa. The following new speciesare described: T. (Molopsis) aenigmaticus sp.nov. (Asian Turkey, „Armenia“ imprecise locality), T. (Molopsis) chaudoirisp.nov. (Asian Turkey, Bursa Villayet, Uludağ Mt., Sakarya (Adapazari) Villayet, Gökdağ Mt.), T. (Molopsis) oyukluensissp.nov. (Asian Turkey, Konya Villayet, Fasihan Pass), and T. (Molopsis) relegatus sp.nov. (Asian Turkey, Bolu Villayet,Mengen env., Dorukhan Pass). The following nomenclatural acts are also proposed: Tapinopterus (Molopsis) molopinus (Chaudoir, 1868) = Tapinopterus (Molopsis) dipojranus brussanus Straneo, 1984, syn.nov.; Tapinopterus (Molopsis)

A New Species

In two European species of the genus Plutomurus Yosii, P. carpaticus Rusek & Weiner and P. unidentatus (Börner), several diagnostic morphological characters are specified and illustrated: body chaetotaxy, number of internal spine-like chaetae on tibiotarsi and number of teeth on claw. The contribution is based on the study of type specimens of both species and specimens of other populations of their distribution ranges. The numerous specimens of the genus Plutomurus collected recently in the Western Carpathian caves are the most similar to P. carpaticus, but differ in macrochaetotaxy and may represent a new species. Three types of macrochaetae on thorax and abdomen of Plutomurus congeners from the Europe and Caucasus are defined. Identification key to European Plutomurus species is provided.
