In February 2023 a single male <i>Mortonagrion</i> was collected at a pool just inside a stand of what appears to be mangrove near the Kampar River and was found to agree well with <i>M. megabinluyog</i>. In June 2023 the same stand of mangrove was entered at a different spot and a few individuals of both sexes were collected. Males agree in their anal appendages with <i>M. megabinluyog</i> but show some small differences in markings. Females have the posterior lobe of the prothorax more rounded in dorsal view than that shown for <i>M. megabinluyog</i> in fig. 6 in Dow & Choong (2015) and two of the females have blue dorsal markings dorsally on abdominal S8, absent in the female paratype. None of these differences seem particularly significant, especially since variation even in the Brunei population can hardly be assessed with a type series of three males and a single female from one small site and we have little hesitation in assigning the Kampar Peninsula population to <i>M. megabinluyog</i>. This record is however surprising, and this species should be looked for not only in coastal areas in other parts of Borneo and Sumatra but also in Peninsular Malaysia.</p> |
