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.

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.

An account is given of an investigation made of the life-histories of Oscinella frit and its parasites in Ontario, Canada, with a view to the possible introduction of suitable parasites into England. The various Chloropid species associated with O. frit in North America are discussed.The life-history of the frit-fly in Ontario is similar to that in England except wheat, not oats, is attacked, and that there appears to be no regular grain-infesting generation, but the insect is never a major pest in Canada.The life-histories of the following six species of parasites are described : Hexacola sp. n., Polyscelis sp. n., Loxotropa sp., Cyrtogaster sp., Callitula bicolor and Spalangia drosophilae. Other hosts from which these parasites have been reared include Chloropids associated with O. frit in wheat, namely O. carbonaria, O. soror, O. minor and Meromyza americana.A brief account is given of the control exerted by these parasites on the population of frit-fly in Ontario and a comparison is made between the Canadian and English parasite complexes. From this it is concluded that S. drosophilae might exert some control of frit-fly if introduced into England.

Plethodontid Salamanders

Territoriality has been documented among plethodontid salamanders in eastern North America, but aggressive interactions among western plethodontids are largely unknown. I examined the responses of three sympatric western Plethodon species (P. vehiculum, P. dunni, and P. vandykei) toward conspecific and congeneric salamanders in two laboratory experiments. In experiment 1, I investigated intra- and inter-specific aggression by the three species, and in experiment 2, I examined aggression and dispersion of the salamanders when fed either a high or a low level of food. In experiment 1, P. dunni were more aggressive than P. vehiculum and P. vandykei, which rarely bit their opponents. In experiment 2, two different food levels had no detectable effect on the aggressiveness of residents. Resident P. dunni (males, females, and juveniles) were equally likely to bite conspecific and congeneric salamanders introduced into their cages. However, their dispersion under cover objects was uniform (suggesting territoriality) only in pairings between conspecific individuals. In contrast, P. vehiculum showed little aggression and were randomly dispersed under cover objects. The variety of responses exhibited by the three sympatric species toward conspecific and congeneric salamanders suggests that their populations are only superficially similar in ecology and may be subjected to different intensities of intraspecific competition.
