Cephennodes ovatus Jałoszyński, 2007: 203,

a secondary junior homonym of Cephennodes ovatus (Nietner), is here replaced with Cephennodes ovatides nom. n.

Although the subgenus Aculeodes Jałoszyński & Nomura (2009) was diagnosed based on female characters, the aedeagi of the type species of Aculeodes, C. ovatus, and C. vegrandis Stevanović, 2009 show similarities that suggest their close relationships. The parameres are free, as in Cephennodes s. str., and the apical group of dorsodistal projections is inserted on a common tubular shaft. These features are added to the diagnosis of Aculeodes, and C. ovatus and C. vegrandis are here placed in Cephennodes (Aculeodes) .

Species of the large genus Cephennodes are morphologically uniform, except for remarkable male dimorphic characters in some species groups, and in general, females are extremely difficult or even impossible to identify. The lectotype of C. ovatus is externally unremarkable, but the aedeagus is unique and not possible to confuse with copulatory organs of any other illustrated species.
