The single- stripe shrew- pouch rat ( Monodelphis unistriata ), also known as the stripe -pointed-mouth- pouch rat or single- stripe short-tailed opossum , is a supposedly extinct marsupial from the genus of the shrew- pouch rats ( Monodelphis ). It occurs or occurred in Brazil and Argentina .
features
Dimensions are only available from the holotype. It has a head-torso length of 140 mm and a tail length of about 60 mm. The top is rust gray. The middle of the back is marked by a single chestnut-colored stripe. The flanks, feet and the underside are yellowish-orange. The tail is two-colored; brownish on the top and yellowish on the underside.
Habitat and way of life
The single-striped shrew-pouch rat was predominantly crepuscular. She looked for food on the ground. Nothing is known about habitat and way of life.
Status and system
The single-stripe shrew-pouch-rat is only known from two specimens collected in 1821 and 1899. The holotype is a male that was caught by Johann Natterer near Itararé in the Brazilian state of São Paulo on March 11, 1821 . It is located in the Natural History Museum Vienna . The second copy was collected on April 9, 1899 by Luis Boccard in the province of Misiones in Argentina and is kept in the Museo Argentino de Ciencias Naturales in Buenos Aires. Johann Andreas Wagner described the taxon as Didelphys unistriata in 1842 . Oldfield Thomas examined the type specimen in 1888 and placed the species in the genus Peramys . The classification in the current genus Monodelphis comes from Ángel Cabrera and José Yepes from 1940. The IUCN lists the single-stripe shrew rat in the category " critically endangered (possibly extinct) ". The main reason for the species' disappearance was believed to be habitat destruction.
