Not evaluated.

Remarks

This recently described species was formerly identified as K. venulatus or K. ateralbus . Kalloconus venulatus is absent from Sal Island, and K. ateralbus has enough mitogenome sequence divergence to be considered a separate species, sister to K. marimaris (see above). The latter is split into two populations inhabiting areas to the east and west coasts of Sal Island. This species has some morphological similarities to K. ateralbus and hence the confusion. Kalloconus marimaris is very variable in background color, with yellow, orange, milky white or brown morphs, whereas in K. ateralbus the background color is always black.
