Paragomphus serrulatus (Baumann, 1898)
Tiger Hooktail


  • scientific: Onychogomphus serrulatus; P. bredoi (Schouteden, 1934); P. longiventris Fraser, 1955; P. xanthus Pinhey, 1966

Type locality: Togo, no locality data available.


Male is similar to P. cognatus by (a) postdorsal stripes well-separated from collar; (b) S5-6 usually extensively pale marked; (c) apices of cerci thick, truncate, often coarsely toothed. However, differs by (1) ranging from NE DRC to W Africa, rather than in eastern and southern Africa; (2) complete pale metepisternal stripe interrupted only in very dark specimens, rather than typically interrupted at least above metastigma and often broken up into three spots; (3) apical segment of the penis bearing a small but prominent dorsal hook on each side; (4) narrower tips of the cerci, with one prominent and often spine-like posterior tooth and several often indistinct anterior ones, rather than several coarse similarly-sized teeth; and (5) clearly longer than wide epiproct in ventral view, rather than almost as wide as long.
