A. Davis 1966). even if a captive L. crassicaudata used to be strictly carnivorous (J. A. Davis 1966), Collins (1973) thought of the normal vitamin to be omnivorous. Nowak and Paradiso (1983) pronounced breeding classes in line with 12 months, one within the spring via the second one after the 1st muddle is weaned and self reliant. Gestation is ready 2 weeks, and younger are raised in grass nests. A Colombian lady taken 10 August carried seven hooked up younger within the pouch (Lemke et al. 1982). The karyotype is 2n = 22, FN = 20, with a metacentric X and an acrocentric Y chromosome (Reig et al. 1977; Seluja et al. 1984). r e m a r ok s : even supposing Krumbiegel (1941b) well-known all named subspecies, C. O. C. Vieira (1949) and Cabrera (1958) prepared L. c. travassosi Miranda-Ribeiro as a junior synonym of L. c. crassicaudata Desmarest. Cabrera (1958) and Xim´enez (1967) taken care of L. c. paranalis O. Thomas, as a legitimate subspecies with L. c. bonaria O. Thomas, as a synonym. Cabrera (1958) additionally thought of L. c. lutrilla O. Thomas, to be a sound subspecies; yet Xim´enez (1967) taken care of the identify as a junior synonym of L. c. paranalis. Marshall (1978a) tentatively famous purely subspecies: L. c. crassicaudata, a larger-bodied, grayish olivaceous to buffy brown animal came upon usually within the rios Paraguay, Parana, ´ and de los angeles Plata drainage basin of south-central South the US; and L. c. turneri, a smallerbodied, tawny to darkish brown subspecies limited to japanese Colombia, Venezuela, and western Guyana. Xim´enez (1967) urged that turneri may possibly turn out to be a species become independent from L. crassicaudata. Cabrera’s (1958:39) inclusion of Didelphis macroura Illiger, 1815:107 (a nomen nudum) within the synonymy of L. crassicaudata used to be in keeping with a false impression of Illiger’s identify. Olfers (1818:205), whose names are likely to be similar to numerous of Illiger’s nomina nuda, dependent Illiger’s “macroura” on Azara’s (1801a:290) “micour´e a` queue longue” and incorporated it within the synonymy of Didelphis murina Linnaeus, 1758, which has no longer been recorded from Paraguay. even if, Olfers’ (1818:205) spelling D. macrura isn't to be thought of an analogous identify as Didelphis macroura, which Desmoulins (1824:492) used for Azara’ (1801a:284) micour´e a` queue grosse, which Desmoulins referred to as “Didelphe a grosse queue. ” Olfers = (1818) D. crassicaudis may well healthy any of 4 different types: 1) a brand new identify with D. crassicaudata Desmarest a senior synonym; 2) a substitute identify for D. crassicaudata Desmarest; three) an mistaken next spelling of crassicaudata Desmarest; or four) as claimed by means of Hershkovitz (1959:338), or an unjustified emendation of D. crassicaudata Desmarest. We reject the final probabilities as the spelling used is in keeping with that of Illiger (1815) and there's no facts, except the identify itself, that Olfers (or Illiger 1815) deliberately changed the identify D. crassicaudata. simply because a brand new identify might or won't have an analogous kind, we ponder D. crassicaudis Olfers a alternative identify, thereby making it a junior goal synonym of D. crassicaudatus, within which case it has an analogous style and kind locality.
