In the original description Butschli stated that female and male lengths had been 1.7 mm and 1.4 mm, respectively, but Steiner gave lengths of 0.98-1.2 mm and 0.92-1.two mm, using a stylet length in each sexes of ten mm. In spite of the similarity in measurements it truly is unlikely that Steiner's specimens would be the very same taxon as the undescribed species, given that stylet length is distinct. Moreover, the tail strategies of Steiner's specimens are sharply pointed, whereas inside the undescribed species they may be rounded. Separation of Anguina from Subanguina is dependent on the structure on the female reproductive method. Additional specimens, specially of reside, gravid females, are needed to study morphology with the gonad for definitive placement in Anguina or Subanguina. NON-DESTRUCTIVE X-RAY IMAGING OF ROOT SYSTEMS INFECTED WITH ENDOPARASITIC NEMATODES. Bernard, Ernest C.1, D.W. McDonald2, R. Michaels2, and B.H. Ownley1. 1Entomology and Plant Pathology Dept., University of Tennessee, 2431 Joe Johnson Drive, Area 205, Knoxville, TN 37996-4500; and 2Phenotype Screening Corp., Suite 10, 4028 Papermill Rd., Knoxville, TN 37909. Observation of nematode-induced root disease is hampered by the opacity of soil along with other increasing media and by the will need for adequate replication to let statistically meaningful but destructive sampling. Observation of symptom development on roots in an X-ray-transparent medium was explored via non-destructive two-dimensional X-ray imaging of cotton and sunflower seedlings. Seedlings have been grown in germination pouches and root systems had been Rper, Groody didn't directly condemn fellow students. inoculated with freshly hatched M.Atodes been studied and described. The moss Hypnum cupressiforme var. cupressiforme was collected in November 2011 at Undesirable Salzungen, Thuringia, dried with heat, and prepared for the herbarium. Soon thereafter terminal swellings had been noted and dissection demonstrated that the swellings contained females, males, and second-stage juveniles. Quite a few galls had been dissected in water. 1 female, a number of males and about 30 of J2 had been revived a single hour after immersion. This species was placed tentatively in Anguina as the female was slightly swollen and heat-relaxed in a near circular pattern (length 1.two mm), but they are not definitive Anguina characters and also the taxon also could fit in Subanguina. Internally the female was badly degraded plus the reproductive tract could not be studied; nonetheless, the metacorpus in all stages appeared to become significantly more substantial than that illustrated for other moss-galling Anguinidae. Males were similar to those of Subanguina brenani (=Anguina brenani), described from Oxford, England, on the moss Pottia bryoides, but have been longer (1.1-1.two mm inside the undescribed species, 0.6-0.7 mm in S. brenani), as well as the stylet and spicule have been longer (13 mm and 32-34 mm vs. ten mm and 25-26 mm). Male and J2 tail tipsMeeting Abstracts 453 were rounded in the undescribed species but sharply pointed in S. brenani. Juveniles were 728-889 mm long and their stylet lengths had been 10-12 mm; S. brenani juveniles weren't described. The undescribed species resembles Subanguina askenasyi, also described from H. cupressiforme, but doubt exists regarding the limits of this species.
