Didelphoxyuris thylamisis n. sp. differs from the only pinworm described from marsupials in the Neotropics (Neohilgertia venusti Navone, Suriano et Pujol, 1990) in having only three oesophageal teeth, non-operculated eggs, females that are didelphic, and males that possess no preanal papillae. Several other species of pinworms have been described from marsupials in Australia, but all are characterized by possessing a buccal capsule that is strongly cuticularized with inter-radial lamellae. These structures are lacking in D. thylamisis. Didelphoxyuris n. gen. is characterized by a mouth opening into a depression and lateral alae composed of two lengthwise crests. All males possess an area rugosa composed of a ventral sagittal crest, a caudal extremity truncated at the level of the cloaca, and four pairs of genital papillae (two pairs lateral adanal and sessile, one pair just posterior to spicule aperture, and last pair at posterior extremity and pedunculated). All females possess an opisthodelphic uterus, a reflexed ovary and a thick and laterally enlarged cephalic vesicle containing a complex reticulated network of rounded confluent vesicles.

Conceptual roots for this meeting ema­nated from discussions initiated during the Ist Workshop chaired by Claude Vaucher and Jean Mariaux at the Museum of Natural History, Geneva in 1993. Eric P. Hoberg http://digitalcommons.unl.edu/parasitologyfacpubs/82 http://digitalcommons.unl.edu/parasitologyfacpubs/82 Tue, 21 Apr 2009 13:57:46 PDT Gerald D. Schmidt was born March 12, 1934 in Greeley, Colorado. After finishing his undergraduate degree in Biology at Colorado College in Greeley (now the University of Northern Colorado) Dr. Schmidt went on to receive his masters degree from Colorado State University (CSU) in 1962 and his Ph.D. in 1964 also from CSU. While At CSU he worked under Dr. O. W. Olsen, first on the helminth parasites of the common snipe, and then, for his doctorate, he studied the embryological development of the Acanthocephala. He became a member of the faculty of UNC in Greeley In 1966. His collaboration with Dr. R. E. Kuntz of the US NAMRU-2 in Taiwan on long-term studies of zoonoses resulted in a large number of publications which increased our knowledge of the biodiversity of the South Pacific region. His many masters and doctoral students have dispersed to all points of the globe and many continue to publish on biodiversity and the systematics of parasites. The thorny-headed worms were his primary focus of study and, despite a lack of institutional support at UNC for such a scientist, he published more than 160 articles in systematics and parasitology. Included in this extensive series are the books Essentials of Parasitology (Wm. C. Brown. 1988), How to Know the Tapeworms (Brown Co., 1970), Handbook of Tapeworm Identification (CRC Press, 1986) and Foundations of Parasitology (with Larry Roberts, Mosby, 1989, four editions.). He was also editor of an influential and forward-looking book entitled Problems in Systematics of Parasites (University Park Press, 1969). Gerald D. Schmidt was honored for his achievements in science and systematics of parasites at a young age by the American Society of Parasitologists with the Henry Baldwin Ward medal and was a board member of the World Federation of Parasitologists, a Fellow of the Royal Society of Tropical Medicine and Hygiene, London, and a Fellow of the Royal Society of South Australia. As a professor at the University of Northern Colorado, he established the local chapter of Sigma Xi, the Scientific Research Society, and served as its first president; he was also a co-founder of the Rocky Mountain Conference of Parasitologists. He served as Secretary-Treasurer of the American Society of Parasitologists during a period of financial and structural rebuilding of the society from 1982-1987. He also served as a co-editor for Systematic Parasitology from 1980 until his death. Gerald was a scholar, teacher and friend. His enthusiasm for the helminths was without limit. He was always ready to relay an interesting parasitological story and his story-telling ability is evident in his book Foundations. His great sense of subtle, dry humor and his joy of reciting a new "limerick" were a part of his personality. Science, the field of parasitology and his friends will always remember him. Dr. Gerald D. Schmidt died on October, 16, 1990, at the age of 56. Scott Lyell Gardner http://digitalcommons.unl.edu/parasitologyfacpubs/81 http://digitalcommons.unl.edu/parasitologyfacpubs/81 Tue, 21 Apr 2009 12:13:19 PDT The parasite fauna of 2 species of fat-tailed mouse opossums from northwestern Argentina is herein presented. Five species of helminths were found, i.e., Pterygodermatites kozeki, Hoineffia simplispicula, Oligacanthorhynchus sp., and a new species of tapeworm, Mathevotaenia sanmartini n. sp. (Cyclophyllidea: Anoplocephalidae). The new species is characterized by a calyciform scolex, relatively few testes (32), and a long cirrus sac; it occurs in fat-tailed mouse opossums at localities above 4,000 m. Those characters make it different from 6 species known to occur in marsupials from the New World, and from other species occurring in armadillos and bats. Didelphoxyuris thylamisis, H. simplicispicula, and Oligacanthorhynchus sp. appear to occur in marmosas from the Yungas region. In contrast, both P. kozeki and M. sanmartini n. sp. appear to occur exclusively in the Puna. F. Agustin Jimenez http://digitalcommons.unl.edu/parasitologyfacpubs/80 http://digitalcommons.unl.edu/parasitologyfacpubs/80 Tue, 21 Apr 2009 11:35:21 PDT We present new records of occurrence and distribution for two species of didelphid marsupials and one species of echimyid rodent. Specimens were obtained from May through August 1991 and June through August 1992 in a study of mammalian diversity of Bolivia, a joint project between the Colección Boliviana de Fauna in La Paz, the Museum of Southwestern Biology (University of New Mexico), the American Museum of Natural History (New York), the Museo "Noel Kempff Mercado" de Historia Natural in Santa Cruz de la Sierra, and the University of California at Davis. This project is an attempt to strength Bolivian collections of natural history as well as to increase the knowledge of the mammals of one of the richest yet still poorly known areas of South America.Specimens were prepared following museum standards and are on deposit in one of these collections. We also obtained tissues (heart, liver and kidney) and parasites for future studies. Most of the individuals were karyotyped and cell suspensions frozen in liquid nitrogen. All tissues, karyotypes and cell suspensions were deposited in the Division of Biological Materials, Museum of Southwestern Biology, University of New Mexico. Jorge A. Salazar-Bravo
