Crenigomphus kavangoensis sp. nov. from the Okavango River, Namibia (Odonata: Gomphidae)


A new species of Crenigomphus is described and illustrated from a type series of eight males and eight females, all collected along the Okavango River in Namibia during December 2004, three non-type adult specimens and several exuviae (holotype ♂ Namibia, N’Kwazi Lodge, 19 xii 2004, deposited at NMNW). Both sexes lack foliations at S8-9 as occur in some Crenigomphus, but the male is peculiar in having exceptionally long cerci. The latter character is normally present in the genus Paragomphus. Other characters typical of Crenigomphus include all wings having a bright yellow costal border, S10 longer than S9 in males, colouration mostly ochreous with few darker markings, and the strong blackish serration at the posterior end of the cerci. The larval characters based on exuviae, one associated with an emerged male, do not allow clear separation from Paragomphus.
