Dohrniphora preacuta sp. n.

( Figs 239–240)

Species recognition. This species belongs to a possibly monophyletic group including D. acuta and D. subacuta , both of which also have two pointed processes on the hind femur, as well as other species of the D. caguanensis group treated above. Both D. preacuta and D. subacuta have three rows of peglike setae, whereas D. acuta has only two. The uniformly dark brown abdominal tergites, other characters in the key, easily distinguish D. preacuta from the other two species.
