Abstract:Protoparmelia capitata Lendemer, a sorediate species, is described as new to science. It is characterized by having large hemispherical soralia. Protoparmelia isidiata Diederich, Aptroot & Sérus., an isidiate species, is reported for the first time from North America. Both taxa produce alectoronic acid, and are shown to be widespread in sub-tropical portions of south-eastern North America. The placement of these two taxa in Protoparmelia is supported by a phylogenetic study of mitochondrial SSU rDNA sequences.

First Time

A new nematode species recovered from the laboratory culture ofDrosophila melanogasteris described and illustrated. The mass reproduction ofPanagrellus levitatussp. n. in the fly culture occurred several times and resulted in a significant reduction of the fly population. Nematode outbreaks happened after the introduction ofD. melanogasterto the culture from natural sources. The new species is morphologically similar toP. ulmi. Partial LSU rDNA and SSU rDNA sequences were obtained and subjected to phylogenetic analysis that demonstrated the affinity of the new species withPanagrellussp. ‘MC2014’ from a red palm weevil. For the first time, the dauer juveniles ofPanagrelluswere described.

The Ptiliidae of the Maritime Provinces of Canada is surveyed. Twenty-nine new provincial records from the Maritime Provinces of Canada are reported including the first records of the family from Prince Edward Island. Fourteen species are recorded for the first time for the Maritime Provinces as a whole. Acrotrichis josephi (Matthews) is recorded for the first time in eastern North America and Acrotrichis haldemani (LeConte) is recorded for the first time in Canada. The genus Pteryx is reported for the first time in Canada. At least 29 species of Ptiliidae are now known to occur in the region. The fauna is briefly discussed in terms of its overall composition, introduced species, and species associated with particular habitats. Saproxylic species found in mature forests are discussed and attention is drawn to their possible relationship to undisturbed forest conditions and the scarcity of old-growth habitats in the region.

Rich Fauna

Invertebrates specialized for life in groundwater (stygobionts) are diverse and widely distributed in Europe but poorly known in North America. A survey of the invertebrate fauna at 14 sites in eastern North America shows that unglaciated ancient terrain in eastern North America contains a rich fauna of stygobionts. Several groups of stygobionts (the polychaete Troglochaetus sp., an undescribed genus of aphanoneuran annelid, a possibly undescribed family of oligochaetes, bathynellacean crustaceans, and microcerberid isopods) are reported for the first time from eastern North America. Stygobionts are infrequent north of the glacial border, suggesting that they have not yet been able to disperse into glaciated terrain. The extraordinarily slow dispersal rates implied by these distributions have important ecological ramifications. The few stygobionts found north of the glacial border may have survived glaciation in subglacial refugia.

Diversity of the anaerobic Heterolobosea (Excavata: Discoba) is only poorly understood, especially in marine environments. We have isolated and cultured 16 strains of anaerobic heteroloboseid amoebae and flagellates from brackish, marine and saline anoxic habitats worldwide. Phylogenetic analyses of SSU rDNA sequences and light-microscopic observations showed that all the strains belong to the family Psalteriomonadidae, the main anaerobic lineage of Heterolobosea, and that they represent eight species from the genera Monopylocystis, Harpagon and Pseudoharpagon. Seven species are newly isolated and described here as Monopylocystis minor n. sp., Monopylocystis robusta n. sp., Monopylocystis elegans n. sp., Monopylocystis disparata n. sp., Harpagon salinus n. sp., Pseudoharpagon longus n. sp. and Pseudoharpagon tertius n. sp. Amoebae, cysts and the ultrastructure of the genus Pseudoharpagon are presented for the first time.

First Time

The polypore Trametes gibbosa (Pers.) Fries, common in Europe and Asia, is reported from eastern North America for the first time. Single basidiospore cultures from Pennsylvania, United States, and Quebec, Canada, were paired with each other and with cultures from the Czech Republic. The North American intercollection crosses were 60% compatible and 100% compatible with the Czech cultures. All the crosses among the Czech cultures were 100% compatible. The recent introduction of T. gibbosa to North America is suggested as a possible explanation for the limited number of mating-type alleles and subsequent incompatibility among the North American cultures.

AbstractRonald Mason’s hypothesis from the 1960s that the southeastern United States possesses greater Paleoindian projectile-point diversity than other regions is regularly cited, and often assumed to be true, but in fact has never been quantitatively tested. Even if valid, however, the evolutionary meaning of this diversity is contested. Point diversity is often linked to Clovis “origins,” but point diversity could also arise from group fissioning and drift, admixture, adaptation, or multiple founding events, among other possibilities. Before archaeologists can even begin to discuss these scenarios, it is paramount to ensure that what we think we know is representative of reality. To this end, we tested Mason’s hypothesis for the first time, using a sample of 1,056 Paleoindian points from eastern North America arui employing paradigmatic classification and rigorous statistical tools used in the quantification of ecological biodiversity. Our first set of analyses, which compared the Southeast to the Northeast, showed that the Southeast did indeed possess significantly greater point-class richness. Although this result was consistent with Mason’s hypothesis, our second set of analyses, which compared the Upper Southeast to the Lower Southeast and the Northeast showed that in terms of point-class richness the Upper Southeast > Lower Southeast > Northeast. Given current chronometrie evidence, we suggest that this latter result is consistent with the suggestion that the area of the Ohio, Cumberland, and Tennessee River valleys, as well as the mid-Atlantic coastal plain, were possible initial and secondary “staging areas” for colonizing Paleoindian foragers moving from western to eastern North America.

AbstractTwo species ofCatinariawith an unusual hepaticolous (i.e. growing on liverworts) lifestyle are described as new to science.Catinaria brodoanais described from species ofCheilolejeuneasect.Leucolejeunea(Lejeuneaceae) growing in south-eastern North America. Catinaria radulaeis described fromRadula flavifolia(Radulaceae) growing in the Cape Horn Archipelago of southernmost Chile, South America. The species are compared with the type ofCatinaria(C. atropurpurea). In addition to occurring on hepatics,C. brodoanais characterized by its cellular exciple, warted ascospores and thallus composed of goniocysts, whileC. radulaeis characterized by its exciple of radiating hyphae, warted ascospores and absence of a lichenized thallus.
