Micrurus albicintus has a record in the Colombian Amazon (see distribution map in Nogueira et al. 2019) and this specimen is morphologically consistent with the species including the number of black rings, according to Roze (1996) males have between 67 and 90, the one in the photos has 72 black rings. PS: Similar coral snakes can be ruled out by the number of black rings, as in the case of M. anellatus which males only have between 34 and 61 black rings (Roze. 1996) and M. medemi which can have around 40 black rings (https:// www .inaturalist.org/observations/115296595) when the red rings are melanized.

According to Grant & Myers (2013) Silverstoneia minutissima differs from S. erasmios, S. gutturalis, S. nubicola, and S. punctiventris in lacking conspicuous dark ventral markings (other species ventrally black, gray, or spotted); S. dalyi has an immaculate venter but usually has dark postrictal markings and is restricted to lowlands (30–450 m). Silverstoneia minutissima is most similar to S. minima, from which it is diagnosed by the light dorsal surfaces of the thighs (dark in S. minima) and different pigmentation on the dorsal surface of thigh (see figure 14 in Grant & Myers 2013).

In addition, Silverstoneia minutissima is primarily distributed in the Río Atrato drainage, on both sides of the upper Río Atrato. Therefore, this specimen was found in the distribution range of the species..
