“…Embryo samples are from the study described in González-Chávez et al (2019). A female of C. fuliginosus (Tomes, 1863) captured during fieldwork was pregnant with four embryos, three of them in the right uterus and one in the left.…”

“…fuliginosus , the best represented species in museums and with the widest geographical distribution (see Patterson, , ; Tyndale‐Biscoe, ), and from Rhyncholestes raphanurus , the most austral‐distributed species of the order (reviewed by Patterson & Gallardo, ). Some of the studied traits in extant caenolestid species include adult morphology (Flores, Abdala, Martin, Giannini, & Martínez, ; Martin, ; Osgood, ), behavior (Kirsch & Waller, ; Martin & González‐Chávez, ), and ecology (González‐Chávez, Rojas‐Díaz, & Cruz‐Bernate, ; Patterson, ; Patterson, Meserve, & Lang, ).…”

The development of caenolestid marsupials (order Paucituberculata) is virtually unknown. We provide here the first description of Caenolestes fuliginosus embryos collected in the Colombian Central Andes. Our sample of four embryos comes from a single female caught during a fieldtrip at Río Blanco (Manizales, Caldas), in 2014. The sample was processed for macroscopic description using a Standard Event System and for histological descriptions (sectioning and staining). The grade of development of the lumbar flexure and coelomic closure differed between embryos, two of them being more advanced than the others (similar to McCrady's stages 30 and 29, respectively). The pericardial and peritoneal cavities were present, the hepatic anlage was organized in hepatic cords, the heart was in its final position, and the mesonephros was functional. Compared to other Neotropical marsupials, an early appearance of the frontonasal‐maxillary fusion and the cervical growth (thickness) was observed; however, absorption of the pharyngeal arches into the body and lung development was delayed. Besides these differences, embryos were similar to equivalent stages in Didelphis virginiana and Monodelphis domestica. Previous proposals of litter size of four for C. fuliginosus are supported.

We present a systematic review of the extinct species included in the family Caenolestidae, one of the few South American metatherian groups that has survived to the present. We perform a cladistic analysis based on a data matrix consisting of all extant and extinct species that have been referred to this family, 100 morphological characters and two sets of molecular data (cytochrome b and cytochrome c oxidase I). Morphological and molecular data were analysed separately and in combination, under maximum parsimony and maximum likelihood methods. As a result, caenolestids are recovered as a monophyletic group within which we formally recognize three new taxa: Caenolestoides miocaenicus gen. & sp. nov., Gaimanlestes pascuali gen. & sp. nov. and Stilotherium parvum sp. nov. from the Early Miocene of Patagonia, Argentina. Stilotherium is the earliest diverging lineage of caenolestids followed by Gaimanlestes, while C. miocaenicus was recovered as the extinct species most closely related to extant caenolestids.
