  1. Trypanosome measurements in μm ± standard deviation; range in parenthesis. Abbreviations: No number of trypanosomes measured, MA midnucleus to anterior, MP midnucleus to posterior, MK midnucleus to kinetoplast, PK posterior to kinetoplast, NL nuclear length, BW body width, TBL total body length, NI nuclear index (MP/MA). Free flagellum not visible in most individuals and its measurements are omitted; kinetoplast of one large trypanosome from Clinus taurus also ill-defined and its morphometrics are also omitted.
