Sisyra nigra (Retzius) View in CoL

Figures 7, 9 View FIGURES 1 – 10 , 33–35 View FIGURES 27 – 35

This species is closely related to and difficult to distinguish from S. vicaria . The R2 vein in the forewing of S. nigra is forked equal to or apical of the junction of the Sc and R1 veins. The length of this fork varied among the S. nigra specimens I examined, but it usually was about one-half the distance to the junction of Sc and R. The head, antennae, and thorax are dark brown to black in color. In lateral view, the ectoprocts of the male terminalia are twice as long as wide ( Fig. 33 View FIGURES 27 – 35 ). In dorsal view, the ectoprocts are roughly parallel-sided for the basal three-fourths, and with the apical one-fourth abruptly arching mesad and tapering to a point ( Fig. 34 View FIGURES 27 – 35 ). The parameres of the gonarcus complex are roughly L-shaped and less than one-half the length of ectoprocts. Female terminalia have tergite 9 broadly triangular in lateral view and with only a posterior articulation ridge ( Fig. 35 View FIGURES 27 – 35 ).

Sisyra nigra View in CoL has a Holarctic distribution and is widely distributed in Canada, Europe and the northern United States. Most previously published North American records for this species have been reported under the name S. fuscata (Fabricius) View in CoL which Leraut (1980) indicates is a junior synonym of S. nigra View in CoL . New distributional records for S. nigra View in CoL are reported here from Newfoundland and Nova Scotia, Canada, and Montana and Vermont in the United States. The adult flight period ranges from June to August. Adults of S. nigra View in CoL and S. vicaria View in CoL are occasionally collected in the same habitats ( Parfin & Gurney 1956), although the former is not as common as the latter.
