title: Wasp-mimicking soldier flies of the Australian Region: revision of Ampsalis Walker, Elissoma White and Lagenosoma Brauer (Stratiomyidae: Clitellariinae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Winterton, Shaun L. (2023): Wasp-mimicking soldier flies of the Australian Region: revision of Ampsalis Walker, Elissoma White and Lagenosoma Brauer (Stratiomyidae: Clitellariinae). Zootaxa 5246 (1): 1-63, DOI: 10.11646/zootaxa.5246.1.1, URL: http://dx.doi.org/10.1094/PDIS-04-22-0755-PDNAbstractThe genera Lagenosoma Brauer, 1882 (= Peratomastix Enderlein, 1914 syn. n.), Elissoma White, 1916 (= Pycnothorax Kertész, 1923 syn. n.) and Ampsalis Walker, 1859 (Stratiomyidae: Clitellariinae) are revised. Three species of Elissoma are redescribed (i.e., E. australis (Kertész, 1923) comb. n., E. brunnea, Hardy, 1933, and E. lauta White, 1916) and seven species are described as new. Similarly, three species of Lagenosoma are redescribed (i.e., L. dispar Brauer, 1882 (= Peratomastix australis Enderlein, 1914 syn. n.), L. pictum Brauer, 1882 and L. propinquum Brauer, 1882) and seven species are described as new. Ampsalis sensu lato is represented by two species in Indonesia and two species in Madagascar; here the Indonesian species are circumscribed as Ampsalis sensu stricto (i.e., A. geniata Walker, 1859 and A. iterabilis (Walker, 1859 )) with two additional species described from northern Australia. Eudmeta Wiedemann, 1830 is diagnosed and a new synonymy identified (i.e., E. marginata (Fabricius, 1805) (= E. coerulemaculata Yang, Wei et Yang, 2010 syn. n. )). A revised key to Clitellariinae genera of the Oriental and Australian regions is presented, as well as keys to species of Ampsalis, Elissoma, Eudmeta and Lagenosoma.

title: Notes on Central Asian Furcula with description of a new species

description: This dataset contains the digitized treatments in Plazi based on the original journal article Morozov, Pavel S., Prozorov, Alexey M., Korb, Stanislav K., Shovkoon, Dmitry F., Gorbunov, Pavel Y., Müller, Günter C., Saldaitis, Aidas, Yakovlev, Roman V. (2023): Notes on Central Asian Furcula with description of a new species. Zootaxa 5319 (3): 373-388, DOI: 10.11646/zootaxa.5319.3.4, URL: http://dx.doi.org/10.11646/zootaxa.5319.3.4AbstractGenitalia of the female holotype of the Central Asian species Furcula terminata (Wiltshire, 1958) (TL: northeastern Afghanistan) were studied for the first time. They showed a clear similarity with the genitalia of Furcula gorbunovi Schintlmeister, 1998 (TL: Gissar Range, Tajikistan) and Furcula mimonovi Schintlmeister, 1998 (TL: Karakalpakstan, Uzbekistan). Males of F. terminata from Afghanistan were not found in the collections. However, the specimens from neighboring Tajikistan and topotypes of F. gorbunovi and F. mimonovi were studied and all of them have pointed apex of the costal process of valva specific for the bifida -group, not the furcula -group as suggested previously. Considering the morphological similarity and overlapping distribution areas of the three studied taxa, two new synonyms are established for F. terminata: F. gorbunovi syn. n. and Furcula mimonovi syn. n. The population of Tian Shan and Alay Range in Kyrgyzstan and Uzbekistan, previously regarded as F. terminata, are described here as a new species based on differences in the genitalia of both sexes.

description: We search for the rare decay $B^{+}\rightarrow K^{+}\nu\bar{\nu}$ in a $362\ \rm{fb}^{-1}$ sample of electron-positron collisions at the $\Upsilon(4S)$ resonance collected with the Belle II detector at the SuperKEKB collider. We use the inclusive properties of the accompanying $B$ meson in $\Upsilon(4S) \to B \kern 0.18em\overline{\kern -0.18em B}{}$ events to suppress background from other decays of the signal $B$ candidate and light-quark pair production. We validate the measurement with an auxiliary analysis based on a conventional hadronic reconstruction of the accompanying $B$ meson. For background suppression, we exploit distinct signal features using machine learning methods tuned with simulated data. The signal-reconstruction efficiency and background suppression are validated through various control channels. The branching fraction is extracted in a maximum likelihood fit. Our inclusive and hadronic analyses yield consistent results for the $B^{+}\rightarrow K^{+}\nu\bar{\nu}$ branching fraction of $\left[2.7\pm 0.5(\mathrm{stat})\pm 0.5(\mathrm{syst})\right] \times 10^{-5}$ and $\left[1.1^{+0.9}_{-0.8}(\mathrm{stat}){}^{+0.8}_{-0.5}(\mathrm{syst})\right] \times 10^{-5}$, respectively. Combining the results, we determine the branching fraction of the decay $B^{+}\rightarrow K^{+}\nu\bar{\nu}$ to be $\left[2.3 \pm 0.5(\mathrm{stat})^{+0.5}_{-0.4}(\mathrm{syst})\right]\times 10^{-5}$, providing the first evidence for this decay at $3.5$ standard deviations. The combined result is $2.7$ standard deviations above the standard model expectation.
