Amynthas Gracilis. This type of worm comes in brown or pink colors. They can grow up to 4-6 inches long and do well in warm weather. These worms help to increase the porosity of the soil while increasing the ease of water circulation in the soil. Eisenia Fetida.Oct 05, 2015 · As a result of this “engineering,” earthworm invasions can have significant effects on soil physical, chemical and biological properties. The species Amynthas agrestis (family Megascolecidae) was introduced to the United States from Asia, and has expanded its distribution range to include relatively undisturbed forests. En este sentido, lo observado es consistente con el comportamiento de las especies de lombrices identificadas en el área de estudio (especialmente, Amynthas gracilis), el cual ha sido replicado en experimentos actualísticos (Fernandez y Escosteguy, 2019).Amynthas agrestis is an epigeic (litter-dwelling) Asian earthworm. It is native from Japan and the Korean Peninsula and has been introduced to the eastern United States, where it has spread widely, predominantly in forests. It has also been recorded from one location in Canada, near the USA border.A different species, Amynthas gracilis, apparently very similar to A. agrestis, was reported in 2016 from Oregon – including within Josephine County, which borders California.

A lectotype for A. barbadensis (Beddard, 1892) now becomes a junior synonym of Amynthas gracilis removing it from nomenclatural consideration. Lectotypes of contenders, A. mauritianus (Beddard, 1892) itself closer to A. gracilis, and A. insulae (Beddard, 1896) appear separate from A. morrisi. Amynthas gracilis survived 15 to 26 C, and Amynthas corticis survived 13 to 26 C (Fragoso et al., 1999).
