Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
Full text linkThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

(mis-identification) Aphnaeus syama formosana ab. nakaharai Naritomi 1941: Kontyukai 91: 618, pl. 4, Fig. 4. Diagnosis. Ssp. lamuae is characteristic by distal band of central symmetry system of hindwing undersides broken posteriorly at 1A+2A (Figs. 10, 12, 14, 16), whereas this band is continuous, forming a complete V-shaped band in the other subspecies (Figs. 18, 20). The appearance of ssp. lamuae is most similar to ssp. sepulveda Fruhstorfer, 1912 of continental China (Figs. 17–20, 30–34) in wing patterns, sharing the feature of distal band of central symmetry system of forewing undersides in touch with parafocal elements. Ssp. lamuae demonstrates profound seasonal variation, with the markings on wing undersides of individuals emerged in dry/cooler months reduced and turning reddish (Figs. 12, 16). By contrast, seasonal variation is absent in ssp. sepulveda, with individuals emerged from all seasons possessing black spots and bands (Figs. 18, 20); posterior margin of costa on valva is smooth in lamuae (Fig. 27), whereas it is unevenly serrate in ssp. sepulveda (Fig. 32).

Paratypes deposited in NHM, NMNS, and NTNU. Bionomics. Female butterfly oviposits on foliage (twig or leaf) of hostplant (Fig. 43, 44) in the presence of associated ants. Larvae are phytophagous but tended by Crematogaster ants on regular basis (Lin 2011). The larvae devour leaves by scratching epidermis and mesophyll. Larvae conceal themselves gregariously in shelters construct- ed by tying dry leaves while not feeding (Figs. 45). Pupation is taken place within the larval shelters (Figs. 46). Hostplants. Plants oviposited by females or utilized by immatures in the wild included Maesa japonica (Primulaceae) (04F53, oviposition), Ardisia crenata (Primulaceae) (09C26, 09J46, larvae), A. cornudentata morrisonensis (Primulaceae) (09H10, oviposition; 10H20, larvae), A. cornudentata cornudentata (Primulaceae) (09K4, 10H27, 10J52, 11D33, larvae), Mallotus japonica (Euphorbiaceae) (10G26, larva) and Smilax odortissima (Smilaceae)(10J41, larvae). Myrmecophily. This butterfly is obligatorily associated with Crematogester amia (09C26, 09H10, 10G26, 10H20, 10J41) and C. popohana (09K4, 10H27, 10J52, 11D33) in the wild, but larvae may complete development without presence of ants in laboratory (Lin 2011). Etymology. The subspecific name lamuae refers to a comic character Lam (Lamu) created by a famous manga artist Rumiko Takahashi. The patterns of wing undersides recall the graphic design of the bikini Lam wears. Remarks. Seitz (1927) states that S. syama in Taiwan is diagnosable by having the ground color of wing undersides being white, but examined specimens and illustrations of literature all have yellow or creamy yellow ground color on wing undersides.Published as part of Hsu, Yu-Feng & Liang, Jia-Yuan, 2020, On systematic status of Spindasis syama Horsfield, [1829] in Taiwan and the Philippines (Lepidoptera: Lycaenidae: Aphnaeini), pp. 485-500 in Zootaxa 4763 (4) on pages 491-494, DOI: 10.11646/zootaxa.4763.4.2, http://zenodo.org/record/376205

Spiranthes nivea var. papillata T. C. Hsu & Suetsugu. Consequently 2023, var. nov.
No full textSpiranthes nivea var. papillata T.C. Hsu & Suetsugu, var. nov. — Fig. 5. ≡ Spiranthes minutiflora Hsu (2016: 187) in Hsu & Chung (2016), nom. illeg., non Richard & Galeotti (1845: 32). Type:— TAIWAN. Ilan: Tsuifong Lake, 1800–1900 m elev., 3 June 2015, T.C. Hsu 7743 (holotype: TAIF496968!). Diagnosis:— Spiranthes nivea var. papillata is morphologically distinguishable from S. nivea var. nivea by its more densely pubescent rachis and ovaries (vs. sparsely pubescent rachis and ovaries), narrower sepals that are white tinged with pink or purple at the apex (vs. wider and entirely white sepals), and papillose labellum disc (vs. almost glabrous labellum disc). Morphological descriptions and illustrations: —See Hsu & Chung (2016: 187), as Spiranthes minutiflora. Distribution and ecology: —This variety is currently recorded around Tsuifong Lake and Taipingshan in northeastern Taiwan. It grows on sunny grasslands, semi-open roadside slopes, and cliffs around 1800–2100 m elev. Flowers were observed from May to July. Etymology:— The specific epithet is named after its papillate lip and papillate-pubescent rachis and ovaries that are diagnostic from the typical variety. Additional specimens examined:— TAIWAN. Ilan Co.: Taipingshan, 21 May 2012, T.-C. Hsu 5742 (TAIF!); same loc., 23 June 2017, T.-C. Hsu 9299 (TAIF!); Tsuifeng Lake, 22 June 2017, T.-C. Hsu 9287 (TAIF!). Taxonomic remarks: — Spiranthes nivea var. papillata shows morphological resemblance to S. nivea and S. hongkongensis, due to their shared autogamous reproductive biology. Althouth Lin (2019) considered it conspecific with S. hongkongensis, this taxon actually differs in having bracts that significantly exceed ovaries, smaller and glabrous basal labellum callosities, ovate labellum, and smaller column. These features imply a closer relationship to S. nivea, but it still differs from S. nivea var. nivea by several morphological characters mentioned in the diagnosis. Given that there are no significant differences in the labellum and column morphology, which are essential characteristics in species delimitation in S. sinensis species complex (Pace et al. 2019), we concluded that the relatively minor differences are attributed to intraspecific variation, describing it as a new variety of S. nivea.Published as part of Suetsugu, Kenji & Hsu, Tian-Chuan, 2023, Taxonomic revision of the genus Spiranthes (Orchidaceae) in Taiwan, pp. 1-10 in Phytotaxa 578 (1) on pages 6-7, DOI: 10.11646/phytotaxa.578.1.1, http://zenodo.org/record/751762
