... some insects has been described in the onychophoran Opisthopatus cinctipes . This pattern has been proposed to be a characteristic of the genus Opisthopatus . To test this assumption, the ultrastructure of embryos ... support of a “long germ band” hypothesis in Opisthopatus was found. Instead, the embryogenesis in representatives of Opisthopatus is more similar to that in other onychophorans ...
