gen. et sp. nov.
(Heteroptera, Miridae, Cylapinae, Fulviini), is described from Brunei Darussalam. A diagnosis, photographs of ...the dorsal habitus, scanning micrographs of selected morphological structures, and illustrations of male and female genitalia are provided for this new species. Its taxonomic placement within the subfamily Cylapinae is briefly discussed. A comparison with the morphologically most similar genus,
Proamblia

Proamblia
are also provided.
Abstract Representatives of the subfamily Cylapinae (Insecta: Heteroptera: Miridae) mostly inhabit the subtropics and tropics. The group currently comprises five tribes: Bothriomirini, Cylapini, ...Fulviini, Rhinomirini, and Vanniini. Additionally, the Psallopinae are sometimes included in this subfamily as a tribe. The interrelationships within Cylapinae are unknown, the monophyly is doubtful, and a phylogenetic study focusing on the entire subfamily has never been published. The molecular and fossil data analyses show that Miridae occurred at least in the Jurassic. The divergence dates for Cyalpinae tribes are unknown. We performed the phylogenetic analysis of Cylapinae based on molecular and morphological data, in addition to a combined dataset. We calibrated the molecular trees with fossil data. The results suggested non-monophyly of Cylapinae. The monophyly of Bothriomirini was confirmed. Cylapini were rendered as non-monophyletic. The Cylapus complex formed a clade with Vanniini, and the monophyly of Vanniini was doubtful. Fulviini were recovered as non-monophyletic, and the representatives fell into two separate well-supported clades. Dating analyses showed that the groups of the suprageneric level distributed across different continents diverged near the boarder between Mesosoic and Cenosoic, that was also true for the Asian suprageneric groups and the South American Cylapus complex. Australian groups of genera diverged in the Cenozoic.
The Compressed Baryonic Matter (CBM) experiment is a dedicated heavy ion collision experiment at the FAIR facility. It will be one of the first HEP experiments which works in a triggerless mode: data ...received in the DAQ
from the detectors will not be associated with events by a hardware trigger anymore. All raw data within a giventime period will be collected continuously in containers, so-called time-slices. The task of the reconstruction algorithms is to create events out of this raw data stream. In this contribution, the optimization of the reconstruction software in the RICH detector to the free-streaming data flow is presented. The implementation of ring reconstruction algorithms which use time measurements of the hits as an additional parameter is discussed.
Abstract
Lygus (Insecta: Heteroptera: Miridae) is a Holarctic genus, and some of its representatives are important pests. Determining the Lygus species identity and their interrelationships is ...challenging. Our study aimed to delimit five trans-Palearctic species of this group: L. gemellatus, L. pratensis, L. punctatus, L. rugulipennis and L. wagneri. We implemented analyses of morphological characters, morphometrics, cytochrome c oxidase subunit I (COI) and 16S rRNA sequences. The results showed that those species could be delimited using morphology and most species pairs were different in morphometrics. Both COI and 16S rRNA were useful for species identification. Resulting phylogenetic trees contained two highly supported clades. One clade included species known from the Palearctic only, the other clade contained species with Nearctic and Holarctic distribution. Species were mostly poorly supported or non-monophyletic. Molecular species delineation approaches yielded results that generally did not correspond to the morphologically delimited species.

The upgraded HADES RICH detector, as well as the future CBM RICH detector, will both use the same Hamamatsu H12700 Multianode PMTs read out by the newly developed DiRICH FPGA-TDC readout chain for ...MAPMTs and MCPs. The upgrade of the HADES RICH photon detector has meanwhile been completed, and we are now looking forward to the upcoming physics run in spring 2019. A brief overview on the status of both detector projects is given and supplemented with the recent test-beam results which confirmed the functionality of the DiRICH development before the start of the mass-production of all DiRICH components needed for the HADES RICH upgrade.
Wavelength-shifting (WLS) films of p-terphenyl have been applied by means of dip-coating on the entrance window of the H12700 multi anode photomultiplier (MAPMT) in order to enhance the UV ...sensitivity. Using coated and uncoated MAPMTs in a CBM RICH testbox in a proton testbeam at the COSY accelerator, an enhancement of the number of hits per ring of 15%–20% depending on cuts has been observed. Due to new fast readout electronics of the RICH detector for the CBM/ HADES experiments, the time response of p-terphenyl has been measured to show a decay constant of 2.35 ns. This compares well with time-resolved fluorescence measurements of the films.
•Sensitivity of H12700 MAPMTs extended to UV wavelengths with p-terphenyl films.•Application to Ring Imaging Cherenkov (RICH) Detectors.•Increase in number of hits per ring due to wavelength-shifting films by 15%–20%.•Fast decay time (2.35 ns) measured with CBM/HADES RICH readout electronics.•Good agreement between CBM/HADES RICH and time-resolved fluorescence measurements.
The Compressed Baryonic Matter (CBM) experiment at the future Facility for Anti-proton and Ion Research (FAIR) complex will explore the phase diagram of strongly interacting matter at high baryon ...density and moderate temperatures in A+A collisions. The energy spectrum will start at 2 AGeV/c and extend up to 11 AGeV/c for the heaviest nuclei at the SIS 100 accelerator set-up. To explore the physics program of CBM, a RICH detector will be employed for electron identification and pion suppression in a momentum range up to 8 GeV/c. Mirror alignment is a key issue for a proper detector operation. The final conceptual design for a monitoring system of the alignment of the mirrors of the CBM RICH detector will be introduced. It consists of a fast qualitative check of the alignment as well as two different methods to derive quantitative numbers for misalignments. A software correction cycle had been developed which, once applied allows to get back to physics performances as in an ideally aligned case.
•A hardware-based method used to quantify mirror rotations is presented.•Errors up to 2.75% of the applied rotation are observed for a vertical rotation.•Errors up to 14.25% of the applied rotation are observed for a diagonal rotation.•A correction cycle correcting ring-track distance with misaligned mirrors is shown.•Software improvements in ring-track matching and electron ID efficiencies are seen.
