Ceroctis korana

description: Ceroctis korana species group
The validity of this heterogeneous assemblage, based only on phenetic similarities, needs confirmation. It is apparently endemic to the southwestern Africa.

Remarks. Types of this species were examined at MNHN.
The taxonomy of this species was discussed by Bologna (2000a), who synonymized the ssp. rudebecki Kaszab, 1956 with the nominate form.
The phylogenetic position of C. amphibia is unclear, but we suggest possible relationships with C. korana and C. karrooensis, due to the common shape of the wide pronotum with similar puncturation, and the similar shape of antennomeres. Actually, C. amphibia is well distinct from the remaining species at least because of the partial red colour of femours.

Oranjemund: Boom River Canyon, 19 km N of Orange River (ESE of Rosh Pinah), 27.8667°S 17.0667°E (SMWN).
Other records: Namibia (Bologna 2000a; Pitzalis et al. 2014). Kaszab (1955b as ab. bisbiinterrupta) cited the species from southern Kalahari, but probably this record refers to the South African portion of this desert.
Remarks. Types of this species were examined at SAMC.
The elytral pattern is variable, due to the extension of the black colouration. Orange-yellow spots are usually estended and partially coalescent, forming transverse irregular fasciae. Small and round spots without fasciae are present in few specimens (E of Windhoek, Diamond Area, Boom River; South Africa, Richtersveld), which appear distinct from the most common phenotype. Male antenna, pronotum and male genitalia are illustrated in Figs 11 A- E.

Other records. Namib Sand Sea desert (Seely 2012); Namibia (Pitzalis et al. 2014).
Remarks. Types of this species were examined at SAMC.
This species is similar to C. karrooensis, but distinct because of the following characters: shiny integuments, deeper and more distanced punctures of head and pronotum, male antennomeres IV–IX less serrate, wider extension of lemon yellow colouration, particularly on the fore fascia.
We suspect that C. gariepina (Péringuey, 1888) from northwestern South Africa could represent only an elytral variation of C. korana.
