Hypomedon debilicornis (Wollaston, 1857)*

Fig. 4

Note.

As reported by Schülke and Smetana (2015), this cosmopolitan species has been recorded from Nearctic, Neotropical, Palearctic, Oriental, and Australian regions. Notably, this species exhibits parthenogenesis wherein females evolved without sexual reproduction, a factor that is believed to have facilitated its spread (Owen and Allen 2000). The species can be distinguished from other Medonina in eastern Canada by its pale body, small but protruding eyes, transverse subapical antennomeres, smooth lateral pronotal margins and lack of velvety appressed pubescence on the forebody. We here extend its distribution northward and newly report the species from Quebec and Canada.
