Craterostigmomorpha. A Head and maxillipedes of Craterostigmus tasmanianus from dorsal. B Horizontal optical section of an autofluorescence preparation (cLSM stack). Single olfactory glomeruli (asterisks) are weakly detectable. C Different horizontal section of the same preparation as in B. The arrow marks the structural composition of the corpus lamellosum. D Histological cross section of the right brain hemisphere showing the proto- and deutocerebrum with the corpus lamellosum (dashed line). E Histological cross section of the left deutocerebrum showing the dorsomedian located olfactory glomeruli. F 3D reconstruction of the brain with deutocerebral neuropils. Blue = olfactory glomeruli, yellow = corpus lamellosum. Contralateral connection of the CL is not shown. Abbreviations: an antenna, cl corpus lamellosum, dc deutocerebrum, ey eye, mp maxillipede, na nervus antennalis, ol olfactory lobe, pc protocerebrum. Scalebars: A = 1 mm, B-E = 100 μm.
