Marmosops soinii is a South American bag species of the genus marmosops . It was only described in mid-2019 and named after the Finnish biologist Pekka Soini (1941-2004), who researched the fauna of northeastern Peru for many years. The species is so far only known from the region of the confluence of the Rio Javari and Río Ucayali in northeastern Peru.
features
Males of Marmosops soinii reach a head trunk length of 11.7 to 13.6 cm, have a 17.7 to 18.6 cm long tail, 18 to 20 mm long hind feet, 21 to 24 mm long ears and reach a weight of 33 to 54 g. Females stay smaller with a head body length of 10.6 to 11.2 cm, a 14.5 to 18.6 cm long tail and a weight of 33 to 38 g. Their hind feet reach a length of 16 to 18 mm and the ears are 22 to 24 mm long. The back fur of the animals is reddish brown, the belly is cream-colored, the sides of the peritoneum between the front and rear legs are gray. The very long tail, the length of which is more than 140% of the length of the head body, is monochrome dark in most specimens, in some the underside is slightly lighter. Front and rear paws are covered with light hair on the upper side. The hair above the metacarpal and metatarsals can also be dark. The females have 7 or 9 teats, 3 or 4 on each side and one in the middle. The scrotum of the males is white or unpigmented. Marmosops soinii can best be distinguished from the closely related and morphometrically very similar glasses slim-pouch rat ( Marmosops ocellatus ) by its red-brown, darker fur and its tail, which is longer in relation to the length of the head.
habitat
Of the 23 specimens examined for the initial description, 13 were caught or shot on lianas, fallen trees or other elevated places 20 cm to one meter above the ground, 5 were on the ground. 15 animals were caught or shot in primary forests , four in secondary forests , 3 in undisturbed swamp forests and one in a house. Ten specimens were caught during the night and another ten at dusk. No information was published in the first description about the diet, activity patterns, reproduction or territorial behavior of the animals.
