Unrooted statistical parsimony networks of haplotypes belonging to <i>C. taenia</i>-like (T) (upper panel) and <i>C. elongatoides</i>-like (E) (lower panel) clades (sensu [<b>13</b>]).

<p>White circles denote haplotypes found in sexual individuals only, dark grey circles denote those found in hybrids only, and light grey circles denote haplotypes shared by both hybrid and sexual individuals. The sizes of haplotypes are proportional to their frequency. Small blank circles represent missing (unobserved) haplotypes. Newly sequenced haplotypes are in bold. Rectangles delimit the hybrid clades I and II.
