Diagnosis (spilosomus). A member of the species M. limbatus, not differing from
the nominotypical subspecies, M. 1. limbatus, in scutellation. but differing
from it Inpattem, having 14-21 round or oval black spots on a red dorsum;
highly irregular, widely spaced blotches on venter; 3-4 black tail rings,
shorter ventrally than dorsally; and a nuchal black ring interrupted ventrally
or no more than one ventral long (as opposed to 31-45 black rings
encircling body; 4-6 black tail rings, longer ventrally than dorsally, nuchal
black ring complete, covering 3 or 4 ventrals).

Etymology. The name spilosomus is proposed as an adjective derived
from the Greek words transliterated as spilo, meaning spot or spotted, and
somus, meaning body.
