Novius canariensis Korschefsky, 1935

Fig. 5A–F, L

Material examined. Árbol Garoé (9.IV.2019), 1 ex. from Juniperus sp. ; El Sabinal (7.IV.2019), 1 ex. from Juniperus sp. ; Mirador de Isora (12.IV.2019), 3 exx. from Euphorbia sp. ; Tigaday (7.IV.2019), 1 ex. from Junipe- rus sp. (leg. J. Romanowski and C. Zmuda) .

Distribution. Endemic Canarian species, known from Tenerife and Gran Canaria ( Eizaguirre 2007; Oromí et al. 2010). New to El Hierro.

Remarks. There were some doubts about the validity of this species. Forrester (2008) wrote that she was unable to find and examine the type series of N. canar- iensis collected on Gran Canaria. However, Korschefsky (1935) drew the habitus of that species, which perfectly fits to our specimens collected on El Hierro ( Fig. 5L ). To check, whether N. canariensis is a distinct species, its male genitalia were compared with the genitalia of mainland N. cruentatus (Mulsant, 1846) collected in Poland ( Fig. 5G–K ). Our investigation confirms that the Canari- an species is clearly different from N. cruentatus .

Differential diagnosis. Novius canariensis ( Fig. 5L ) can be separated externally from N. cruentatus ( Fig. 5K ) by the shape of red maculae on elytra. In N. canariensis the central part of elytra is occupied by a complete transverse band, whereas in N. cruentatus there are two small red, rounded maculae on each elytron, one close to the lateral margin, second close to sutural line. Sometimes these maculae are larger but they never form complete transverse band. Differences in male genitalia: in N. canar- iensis tegminal strut short, penis guide with blunt apex ( Fig. 5E ), in lateral view regularly curved ( Fig. 5F ), in N. cruentatus tegminal strut long, penis guide pointed ( Fig. 5I ), in lateral view sinusoidal ( Fig. 5J ).
