Genus Stenocnemis Selys, 1886

Type species: Allocnemis pachystigma Selys, 1886


The only species, S. pachystigma, is a fairly large damselfly restricted to the Lower Guinean rainforests, occurring from south-eastern Nigeria through Cameroon and Gabon to western Congo-Brazzaville. It typically occurs near waterfalls, the larvae living in trickles and the spray zone, but adults have also been seen close to fast rocky streams. It may be found with the unrelated Neurolestes trinervis, which it resembles remarkably in coloration (black with orange markings on face and front of thorax, pale blue abdominal segment 9) but not its resting posture with closed wings and hanging abdomen. A form with dull green rather than orange markings in Gabon may represent a second species. [Adapted from Dijkstra & Clausnitzer 2014]


No diagnosis of this very distinctive genus is presently available.
