A
new approach is also proposed: the presence/absence of the different
toxins detected by MALDI-TOF-MS analysis of the venom of
multiple specimens from C. sanguinolentus, C. lividus and C. conco
n. sp. can be coded in a matrix, similar to traditional analyses of
morphological characters. Chemical signals, including toxins, have
previously been used as characters to confirm an existing phylogeny,
using classic phylogenetic approach or clustering methods
(Nascimentoa et al., 2006), but rarely to help recognizing a new
species.
