Podagrion obscurum (Westwood, 1847)

Palmon obscurus Westwood, 1847: 260 . WA King George´s Sound. Transferred to Podagrion by Dalla Torre, 1898: 370. Bouček (1988): 141, 152 (Fig. 202).

Remarks. Bouček (1988) and Grissell (1995, referring to Bouček (1988)) mention that P. obscurum (Westwood, 1847) is close to P. koebelei by sharing the carinate pronotal collar. Thus, P. obscurum most probably belongs to Lasallegrion . Based on the collecting locality and other characters given by Bouček (1988), P. obscurum is most probably conspecific with L. virescens . The latter therefore could be considered as junior synonym of P. obscurum . However, we were unable to locate the single specimen that had been designated as lectotype by Bouček (1988) and which should be located at the Oxford Museum. It bears a label written by Graham ( Bouček 1988). We also tried to locate it at the Natural History Museum London, because parts of the Graham collection are located there, but without success. We decided to keep those two species as separate species and leave the status of P. obscurum unclear until the type will be found.
