The genus Catenulispora was created by Busti et al. (2006)
to accommodate Gram-positive, aerobic organisms that
formed branching hyphae, non-fragmentary vegetative
mycelium and aerial hyphae that were able to septate in
chains of cylindrical arthrospores. At the time of writing,
the genus comprised four recognized species, namely
Catenulispora acidiphila (Busti et al., 2006), Catenulispora
rubra (Tamura et al., 2007), Catenulispora subtropica and
Catenulispora yoronensis (Tamura et al., 2008).
