Gomphus lucasii Selys, 1849
Algerian Clubtail

Type locality: Algeria, no locality data available.


Replaces G. simillimus in Algeria and Tunisia, where it is the only species of its genus. Strongly resembles G. simillimus but may be even paler than individuals of that species from Morocco. S8-9 are said to be brighter yellow and the black lines on the thorax are especially thin; the yellow antehumeral stripe is bordered by two much finer black lines, of which the anterior one is usually not connected to the black flanking the mid-dorsal crest. There are mid-dorsal yellow dots on abdominal segments 8 and 9, which do not reach the posterior segment margins. Legs are black, with yellow lines along the segments. Because both species are variable, identification must be based on hand characters. Male’s upper appendages are less diverging and with more tapering tips than G. simillimus and they eclipse the lower appendages less perfectly (view from above). The female’s vulvar scale is shorter.
