ヤスデ2種で新たに確認された抱卵行動

抄録

We observed egg-brooding behavior in two Japanese millipedes, Eutrichodesmus elegans (Miyoshi, 1956) (Polydesmida: Haplodesmidae) and Cryptocorypha sp. (Pyrgodesmidae), under field conditions. In the former, females remained curling the body around the soil-made mound-like egg-chamber (containing eggs) constructed on dead leaves in the litter. In the latter, a female brooded an egg-mass under the bark of a decaying fallen log.
