Collection and habitat data.

The only previously known adults from the type series of Mitosynum vockerothi fromKouchibouguac National Park, New Brunswick were collected from pan traps set at the edge of a sphagnum bog ( Campbell 1982). Campbell (1982) suggested that this species, which has reduced eyes and wings, might live in deep layers of leaf litter or in clumps of moss. The recently collected adults of this species were sifted from a large sphagnum and Polytrichum commune Hedw. (common haircap moss) hummock near the margin of a small pond and from a layer of sphagnum and leaf litter in the bottom of a deep old tire depression in an 8.5-year-old regenerating mixed forest, supporting Campbell’s suggested habitat association. Adults were collected during June, July, and August.

Comments.

Mitosynum vockerothi was described from two female specimens ( Campbell 1982). Here, we provide an illustration of the dorsal habitus (Fig. 1) and illustrate the male genitalia of this species for the first time (Fig. 2).
