DiagnosisDiagnosis: Bothrocophias myrringae sp. nov. can be distinguished from all its congeners by the following combination of characters: (1) 157–161 ventral scales in females, 152–155 ventral scales in males; (2) internasal scales in contact or separated by a single small scale (3) absence of canthorostral scales; (4) lacunolabial scale usually present; (5) hemipenial lobes slim and cylindrical, moderately capitate distally, weakly ornamented toward the apex with large and scarce calyces with weakly spinulate edges; (8) bifurcation point of the hemipenial lobes about 2–4 sudcaudal scales; (9) hemipenial body ornamented by numerous mesial spines that increase in size from the center to periphery of the hemipenial body and arranged in oblique lines; (10) in sulcate view, lateral and mesial spines of the hemipenial body variable in size; (11) sulcus spermaticus walls weakly defined; (12) usually more than 28 dark-brown bands and/or opposite or juxtaposed trapezoid-shaped blotches with paler centers dorsally; and (13) ventral surfaces of the tail with bright reddish or orange-reddish speckles with black spots without a regular pattern and heavily marked with dark pigment towards the base (Fig. 7). (Angarita-Sierra et al. 2022) 
EtymologyNamed after the Latin translation of the Spanish nickname “Mirringa,” which means “pinch” or something very small. The word “Mirringa” was popularized by Rafael Pombo (1833–1912), a Colombian poet and writer who wrote a popular fable titled “Mirringa Mirronga. The name of the new species is in honor of the educator Myriam Sierra Guerrero (mother of the first author).
