One hundred and thirty-four species of mosses and 18 species of liverworts are reported from Nachvak Fiord and 22 mosses are reported from Saglek Fiord. Nineteen of the mosses had not previously been reported from Labrador and 49 are new to northern Labrador. Seven of the liverworts are new to Labrador. Brophyte species new to eastern North America are Anastrophyllum assimile, Hygrophypnum cochlearifolium (possibly) and Lophozia cavifolia. The record of Lophozia cavifolia represents an addition to the hepatic flora of North America (excluding Greenland). The North American distributions of Hydrogrimmia mollis, Marsupella revoluta and Trichostomum arcticum are mapped. The high incidence of disjunct species in the bryoflora of the Torngat Mountains is discussed in relation to the proposed glacial history of the area.

The ongoing usefulness of Table 1 in the Zootaxa paper Comprehensive taxonomic, faunistic, biological, and geographic inventory and analysis of the Sciomyzidae (Diptera: Acalyptratae) of the Delmarva region and nearby states in eastern North America (Murphy et al. 2018) is compromised by impermanent literature-citation numbering. To secure Table 1 as a permanent resource for the study of Sciomyzidae, provided herein are bibliographic data for the 59 works cited in that paper by Bibliography of Sciomyzidae (“ScioBiblio”) number only. Details are provided regarding the history of the ScioBiblio and plans to reorganize and publish it.

Abstract This study integrates biogeographical and phylogenetic data to determine the evolutionary history of the New World Dermacentor, and the origin of D. variabilis. The phylogenetic reconstructions presented here strongly support the hypothesis of an Afrotropical origin for Dermacentor, with later dispersal to Eurasia and the Nearctic. Phylogenetic and biogeographical data suggest that the genus reached the New World through the Beringia land bridge, from south-east Asia. The monophyly of the genus is supported, and most of the New World Dermacentor species appear as monophyletic. Dermacentor occidentals constitutes the sister lineage of D. variabilis, and the latter is subdivided into two well-supported clades: an eastern and a western clade. The western clade is genetically more variable than the eastern. The genus Dermacentor probably originated in Africa, and dispersed to the Palearctic and then to the New World through the Beringian route. Dermacentor variabilis appears to have originated in western North America, and then dispersed to eastern North America, probably in a single migration event.
