Nervous system in dwarf males of Dinophilus gyrociliatus. Animals are oriented with the anterior end to the left, a Acetylated α-tubulin-like immunoreactive filaments shown in “glow”, indicating one pair of protonephrida and the individual ciliary fields, b acetylated α-tubulinergic-like immunoreactive filaments shown in red, serotonin-like immunoreactive perikarya and fibres in yellow, labelling of DNA with DAPI in blue with focus on the penile ganglion. Abbreviations: avcf – anterioventral ciliary field, n – nephridium, pg – penis ganglion, pnc – penis nerve cord, pvcf – posterior ventral ciliary field, spvnc – serotonin-like immunoreactive perikarya of the ventral nerve cord, test – testis, vcf – ventral ciliary field
