Myzostomes from Papua New Guinea, with related Indo-West Pacific distribution records and description of five new species

Eighteen species of myzostomes were found in association with crinoids collected in Papua New Guinea. Thirteen of the former are described by means of in vivo, light microscopical, and SEM-based observations. Five are new to science: Myzostoma cuniculus, M. laingense, M. nigromaculatum, and M. longitergum are ectocommensals; Contramyzostoma sphaera is a parasite living in a soft cyst induced upon its host. The eight previously described species, six of which are redescribed in detail, include Myzostoma ambiguum Graff, M. capitocutis Eeckhaut, VandenSpiegel and Grygier, M. fissum Graff, M. mortenseni (Jägersten), M. polycyclus Atkins, and M. stochoeides Atkins, as well as Hypomyzostoma crosslandi (Boulenger) and Notopharyngoides aruensis (Remscheid). Most are ectocommensals but the last is an intradigestive symbiont. New Indo-West Pacific distribution and host records for all eight are listed, based on surveys of museum collections, and their entire range are mapped. Hypomyzostoma Perrier, 1897 (type species Myzostoma folium Graff) is resurrected for one of the species-groups previously recognized within Myzostoma, and a lectotype is selected for H. crosslandi. Specimens from Singapore previously identified as M. elegans Graff are reassigned to M. capitocutis

Measurement of D0-D0 mixing and search for CP violation in D0→K+K-,π+π- decays with the full Belle data set

We report an improved measurement of D0 – D‾0 mixing and a search for CP violation in D0 decays to CP -even final states K+K− and π+π− . The measurement is based on the final Belle data sample of 976 fb −1 . The results are yCP=(1.11±0.22±0.09)% and AΓ=(−0.03±0.20±0.07)% , where the first uncertainty is statistical and the second is systematic
