L3 body lengths.

Violin plot of the L3 body lengths of identified Onchocerca spp. in S. damnosum s.l. from North Cameroon. Species identification is based on morphological (light grey) and molecular-genetic (dark grey) characteristics. Two genotypes of O. ochengi, O. ochengi s. str. and O. ochengi 'Siisa', are shown based on their mitochondrial clades. ***P < 0.001; **0.01 > P > 0.001; *P < 0.05.
