Parameters	Minimum value	Maximum value	Mean	SD
Sample size = 28. SD = standard deviation. L = total length including free flagellum. F = length of the free flagellum. NA = distance from the middle of nucleus to the anterior end. PN = middle of the nucleus to the posterior end. PK = posterior end to the kinetoplast. KN = middle of nucleus to the kinetoplast. W = width. NI = nuclear index (PN/NA). KI = kinetoplastic index (PN/KN). Terminology according to Hoare (1972).
