The Andean swamp rat ("
ebriosus") is a species of rodent in the family Cricetidae. It is the only species in the genus
Phyllotini are mostly opisthodont, but "Auliscomys" and "Galenomys" are orthodont and have sometimes even been described as proodont, and "Eligmodontia", "Loxodontomys", and some species of "Calomys" are hyper-opisthodont. "Irenomys", "Reithrodon", and "
", formerly classified as phyllotines, are also hyper-opisthodont. Oryzomyini are also mostly opisthodont, but "Amphinectomys savamis", "Handleyomys fuscatus", "Melanomys caliginosus", "Mindomys hammondi", "Scolomys melanops", and "Sigmodontomys aphrastus" are orthodont.
Most members of the tribe Phyllotini have the antorbital bridge located higher than is usual in Sigmodontinae ("Calomys" and "Andalgalomys" show the normal sigmodontine condition). A similar condition characterizes "Euneomys", "
", "Reithrodon", which are no longer considered phyllotines, but to an even larger extent than in most actual phyllotines; in "Euneomys", the antorbital bridge is inserted on the upper surface of the skull. Most phyllotines have zygomatic spines, but the structure is more well-developed in "Reithrodon". The zygomatic plate not extending backwards to the first molars is a diagnostic character of phyllotines.
In 1926, American zoologist Colin Campbell Sanborn collected some rodents in Uruguay, which he identified as "Holochilus vulpinus" (currently "Holochilus brasiliensis") in his 1929 report on the collection. When his successor at the Field Museum of Natural History, Philip Hershkovitz, reviewed "Holochilus" in 1955, he recognized that the series from Uruguay contained two species, one close to the forms of "Holochilus" found across much of South America, and another unique to Uruguay and southern Brazil; he named the latter as a new species, "Holochilus magnus". Hershkovitz identified "Holochilus" as one of the members of a "sigmodont" group of American rodents, also including "Sigmodon", "Reithrodon", and "
", on the basis of its flat-crowned molars, which are lophodont (the crown consists of transverse ridges). In agnus" was also recognized in the Late Pleistocene of Buenos Aires Province, Argentina, and in 1982 it was recorded from Rio Grande do Sul in southern Brazil.
Although reproduction occurs around the year, there is a peak during the summer (November to April). Molting mostly occurs during autumn and winter (April to August). At one locality in Mendoza, "Akodon spegazzinii" occurs at an estimated density of 21 individuals per hectare (8.5 per acre) and has a home range size of about 300 m (3200 sq ft). A number of sigmodontines have been recorded as occurring with "A. spegazzinii", including "A. caenosus", "A. simulator", "
ebriosus", "Abrothrix illuteus", "Reithrodon auritus", "Andinomys edax", and various species of "Eligmodontia", "Necromys", "Calomys", "Oligoryzomys", "Oxymycterus", and "Phyllotis". The tick "Ixodes sigelos" has been recorded on "A. spegazzinii" in Tucumán. In addition, the mites "Androlaelaps fahrenholzi", "Androlaelaps rotundus", and "Eulaelaps stabularis" and the flea "Cleopsylla townsendii" are known from the species.
