The
Rhamphobrachium complex is revised. Three species each are recognized for
Brevibrachium and
Longibrachium, of which
B. augeneri and
L. longipes are newly described. Two sub genera of
Rhamphobrachium are established:
R. (Rhamphobrachium) containing two species, and
R. (Spinigerium) n. subgen., containing 10 species, of which four [
R.(S.) hutchingsae,
R.(S.) noeli,
R.(S.) pettiboneae and
R.(S.) pyriforme] are described as new. Three additional species,
R.(S.) bipes,
R.(S.) brevicornutum and
R.(S.) cristobalensis, known only from juveniles, are treated as
incertae sedis. Keys to adults and descriptions of all species are provided.
