Analysis of immune-related loci identifies 48 new susceptibility variants for multiple sclerosis
No full textUsing the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 × 10−4). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703 healthy controls. In these 80,094 individuals of European ancestry, we identified 48 new susceptibility variants (P < 5.0 × 10−8), 3 of which we found after conditioning on previously identified variants. Thus, there are now 110 established multiple sclerosis risk variants at 103 discrete loci outside of the major histocompatibility complex. With high-resolution Bayesian fine mapping, we identified five regions where one variant accounted for more than 50% of the posterior probability of association. This study enhances the catalog of multiple sclerosis risk variants and illustrates the value of fine mapping in the resolution of GWAS signals

Israelsson leg, ZML; 1 female England, Barcombe, Devon, 1924-07-04, oak (ex coll. C.J. Saunders), BMNH. Description: Moderate-sized, subdepressed, similar in shape to L. nebulosus (L.) (Fig.2). Body length: 5.0– 9.2 mm in males, and 6.4–9.5 mm in females. Entire surface covered with whitish pubescence with irregular blackish spots, forming an irregular and broad blackish band near base, and most often, an oblique to blackish band behind middle (Fig. 2). A whitish area on the middle of the elytra, between the anterior and posterior dark bands, often with numerous small dark spots. Pronotum covered with a mixture of brownish and yellowish pubescence forming a pattern of lighter spots or transversal bands medially (Fig. 4). Pronotum is wide, often with three to five raised tubercles: two close to the posterior margin, one longitudinally elongated medially, and two close to the anterior margin. Area between four marginal tubercles often covered with yellowish pubescence. Pronotal punctuation relatively coarse and more concentrated medially. Frons more protruding and wider than that of L. nebulosus (Fig. 6). Maximum width of frons (mean ± SD: 1.23 mm ± 0.16; n=20) significantly greater than that of L. nebulosus (0.98 mm ± 0.13, n=20) (t-test, P <0,0001). In order to eliminate any influence of body size, an index (maximum width of frons/maximum width the right eye) was used, which also resulted in significant differences (t-test, P<0.0001). Posterior margin of last visible abdominal segment (ovipositor) of female covered with a dense plume of long hairs (Fig. 8). Body length of examined males (7.83 mm ± 0.88, n=87) significantly greater than that of L. nebulosus males (7.05 mm ± 0.74, n=87) (t-test, P<0.0001). Examined females significantly longer (8.21 mm ± 0.70, n=61) than L. nebulosus females (7.39 mm ± 0.75, n=65) (t-test, P<0.0001). Aedeagus (Fig. 10): approx. 1.7 mm long, relatively broad and stout, slightly widened to the middle and thereafter only slightly narrowed and curved towards apex, ventral ridge protruding, forming a distinct apical tip, often elongated and pointing ventrally. Dorsal ridge with a rounded apex. Microscopic sclerites inside internal sac forming a circular head without a “V-shaped” structure and a "T-shaped" end found in L. nebulosus. Parameres (Figs. 12 & 14): approx. 1.8 mm long, flattened dorso-ventrally, not separated, forming a straight inner line towards apex, apex with sharp edge inwards and more rounded laterally; with a mixture of fine and coarse fringes of relatively short, brownish hairs well concentrated at edge of apex, also scattered single hairs medially towards apex. Basal part of parameres protruding, giving it a swollen appearance. Surface medially along inner margin and predominantly towards apex often covered with weak transversal micro-reticulation. Base of tegmen at lower part of lateral lobe extended and forming a straight line dorso-ventrally, and not twisted in the middle. Proctiger (8 th tergum; Fig. 16): approx. 1.0 mm long and densely covered with long coarse yellowish, brownish or black hairs distally towards posterior margin, covering entire surface medially. Surface not shining medially, with distinct square-formed micro-reticulation both medially and laterally. Posterior margin extended and often forming a distinct pointing edge, almost triangular. Spermatheca (Fig. 17): yellow to brown, relatively short and stout, widened at base, and acutely curved towards apex. Apex with an elongated head. Comments: The genitalia characteristics of both sexes amongst all dissected specimens of the two sibling species of Leiopus were found to be stable. We found no similarities in the genitalia characters between L. linnei, and any of the examined Palaearctic species of Leiopus. The male genitalia characters of L. insulanus, are similar to those described for L. nebulosus but not L. linnei. Etymology: This species is named in honour of Carl von Linné, who introduced the binary nomenclature. The final part of the work was made during 2007, which corresponds with the 300 th anniversary of Linnaeus’s birth. Cerambyx nebulosus was described by Linnaeus and this is an additional reason to dedicate the name of the sibling species to him.Published as part of Wallin, Henrik, Nylander, Ulf & Kvamme, Torstein, 2009, Two sibling species of Leiopus Audinet-Serville, 1835 (Coleoptera: Cerambycidae) from Europe: L. nebulosus (Linnaeus, 1758) and L. linnei sp. nov., pp. 31-45 in Zootaxa 2010 on pages 39-4

Panurginus Nylander 1848
No full textGenus Panurginus Nylander, 1848 Panurginus Nylander, 1848: 223. Type species: Panurginus niger Nylander, 1848, monobasic. Small (4–12 mm), black, poorly pubescent bees; males often with yellow on clypeus and parts of legs. Episternal groove completely absent. Propodeal triangle has at least minute hairs laterally. First recurrent vein is close to first submarginal crossvein (basad to distad from) (Michener, 2007). The genus Panurginus was established by Nylander (1848) for the Siberian species P. niger. Holarctic in distribution, Panurginus was known by 20 species in the Old World (Patiny, 2003) and 18 species in the nearctic region (Hurd, 1979; Michener, 2007); 7 more species are described herein from the temperate areas of Asia. Though these small, dark colored bees from the first glance appear uniform, they often possess some bright and stable specific characters: e.g., shape of clypeus (usually obtuse, latero-apical angles can be slightly (female of P. romani) or greatly protruded (male of P. arsenievi sp. n); shape of basal plate of labrum (usually transverse, flattened dorso-ventrally, twice wider than long, at P. c r a w f o rd i it is longitudinal or knob-like); shape and proportions of antennal or tarsal segments. For identification of males, the ventral side of metasoma shows fine specific characters, and specifically modified apexes of pregenital sterna and genitalia can be used for identification even without taking metasomal segments apart. Although the black body of both genders, and yellow clypeus and parts of legs of male are the most common patterns among the palearctic species, males of some xerophilic forms from Middle and Central Asia bearing more yellow on head (labrum, scape) or other body parts (e.g., P. m o r a w i t z i Friese, P. semiopacus F. Morawitz); yet males of some species have black clypeus (in the studied fauna not represented). As a rule, the body pubescence of most species is unremarkable, short and sparse, longer on head, mesosoma and sometimes on metasomal sterna; hairs are white, with warm tint on the tergal fimbriae. However, some south Siberian species differ by their more plentiful pubescence, which cover even marginal zones of metasomal terga, which are usually impubescent (P. alpotanini sp. n., P. m i k n o sp. n. and P. k o z l o v i sp. n.). The pattern of microsculpture on particular parts of the body (e.g., mesepisterna, T 1 –T 3, propodeal triangle) is usually very much helpful for the keying of species. Females have relatively smooth clypeus with deep pits a few diameters apart on disc, and dense to confluent on periphery; only one species (P. kropotkini sp. n.) has variant clypeal surface: shagreened (covered with a closely-set, fine, irregular roughness), with deep pits merged to confluent creating longitudinal grooves. In all studied species the genal area along the eye impunctate and shiny. Panurginus bees nest in the ground and visit a wide variety of flowers; sometimes they become oligolectic on Brassicaceae, which is very unusual among bees (Michener, 2007).Published as part of Romankova, Tatiana G. & Astafurova, Yulia V., 2011, Bees of the genus Panurginus in Siberia, Far East of Russia, and Allied Areas (Hymenoptera: Andrenidae, Panurginae), pp. 1-35 in Zootaxa 3112 on pages 2-3, DOI: 10.5281/zenodo.20064
