Distribution. Endemic Canarian species (see remarks below), present on La Palma, La Gomera, Tenerife and Gran Canaria ( Oromí & Báez 2010). By some authors ( Fürsch 1987; Eizaguirre 2007; Nicolas 2010) reported from the Canary Islands under the name Nephus peyerimhoffi ( Sicard, 1923) . New to Fuerteventura.

Remarks. The species was synonymized with N. peyerimhoffi ( Sicard, 1923) by Fürsch (1987). Canepari (2009) examined specimens of N. peyerimhoffi from Sardinia and stated that the two species are clearly separate. He resurrected Scymnus incisus from the synonymy with N. peyerimhoffi , without examination of the type series of S. incisus nor other specimens from the Canary Islands. He placed that species in original genus of its description, Scymnus Kugelann. Our study revealed that type specimens of S. incisus have identical male genitalia as our specimens collected from Fuerteventura (depicted in Fig. 5 E–H) but different from those of N. peyerimhoffi pictured in Canepari (2009). Therefore, we confirmed that S. incisus and N. peyerimhoffi are different species. Moreover, incomplete abdominal postcoxal lines not reaching anterior or lateral margins of abdomen and 10-segmented antennae clearly place S. incisus in the nominate subgenus of the genus Nephus Mulsant. Thus , N. peyerimhoffi should be deleted from the list of ladybird beetles inhabiting the Canary Islands.
