C&P4's key is meant for the race cerberus only & that only for the usual forms. To include the uncommon variations will surely overlaps with that of amphrysus.

In the same way, the female of ssp. ruficollis of T. amphrysus may have the large black submarginal spots not actually touching each other, i.e. not conjoined, but are joined to the marginal spots.
The female is identifiable by other means; the forewing is brown never black; the vein-stripes are arranged in such a way that there is a square area of dark brown in the basal 1/2.
The thorax on the underside of both sexes is totally black, and never with the red mark seen in helena .
