Comments. This species can be confused with C. mindanaoensis (Cassola, 2000) (Fig. 3) for having similar elytral maculation, but can be easily distinguished by the pronotum, coppery green or bluish with scarce setae at the lateral sides in C. cabigasi (vs. highly pubescence with coppery bluish green sometimes coppery red in C. mindanaoensis ). Moreover, the elytral suture in C. mindanaoensis is lined with coppery red (vs. absent in C. cabigasi ).

Most specimens of C. cabigasi are dark blue when viewed dorsally, sometimes almost black and with dull elytra. The elytral punctation is not visible through (unlike C. mindanaoensis and C. lacrymosa ). Two discal dots show a tendency to almost coalesce with each other through a narrow lineole in between, which is sometimes poorly visible or almost effaced ( Medina et al. 2021). Unfortunately, Cassola (2011) in the description of this species did not provide an image of the aedeagus. High quality image of aedeagus, showing endophallus structure (Fig. 2c) is provided here for the first time.

Ecology. Consistent with the previous observations ( Medina et al. 2021), the species were collected in relatively higher elevations with good forests along the fluvial ecosystem. Among the three Calomera species in Mindanao, this one is considered the rarest to find.

Distribution. Endemic to Mindanao (Misamis Oriental, Gingoog (type. loc.); Bukidnon, Impasug-ong; Davao de Oro: New Bataan, Cagan; Davao Oriental: Cateel, Brgy. Maglahus – a new faunistic record.
