Neobisnius jucundus (Horn, 1884)

Fig. 7

Note.

See Frank (1981) for identification. Neobisnius jucundus was originally described by Horn in 1884, based on two female specimens from South Carolina. It has since been found to have a widespread presence in North America, extending into several Canadian provinces ( Bousquet et al. 2013). Here we further extend its known Canadian distribution to include southern Quebec. It becomes the fifth species of the genus known from Quebec. Among the bicolored species of the genus, it can be recognized in eastern Canada by the following combination of characters: head longer than wide and with obvious microsculpture dorsally; eyes occupying ~ ⅓ of head length; elytra narrowly pale at apex (<40%); one or more palpomeres of maxillary palpus darkened. The species can also be recognized by the distinctive shape of the aedeagus ( Frank 1981).
