Abrothrix lanosus, distributed throughout southern South America, is one of the least known Patagonian sigmodontine rodents. So far, neither a topotype from the type locality, the Madre de Dios Archipelago (Chile), neither specimens from adjacent areas have been collected. In this contribution, seven new recording localities and a topotype are given. The measurements of gross morphological features, including the cranium of the first topotype collected and other seven individuals are reported. Moreover, the findings establish new northern (48°11’ S, 74°25’ W) and western (49°25’ S, 75°27’ W) distribution limits in Chile for the species.

The identity of Carex trichodes, a species only known from the collection of the type material made in 1854 is clarified after finding it in the wild in the vicinity of the type locality. It is concluded that C. trichodes was proposed based on stressed plants corresponding to the same taxon later described as C. lateriflora.

Ulota pygmaeothecia (Müll.Hal.) Kindb. and Ulota luteola (Hook.f. & Wilson) Wijk & Margad. are two epiphytic mosses from the evergreen Magellanic rainforests of southern South America. Both mosses have been considered as distinct species since their original description, with their specific status retained following the comprehensive review by Nicolajs Malta of South American Ulota (1927). Recently the synonymization of U. pygmaeothecia and U. luteola was proposed (Wang & Jia 2016), based mainly on the similarities stated in the protologues and the study of the available type specimens of U. pygmaeothecia and U. fulvella, as the type materials of U. luteola were lost in the mail. In the present paper, all available type material for names associated with these two taxa, together with additional specimens recently collected, have been studied in depth. As a result, it has been found that both mosses show important sporophytic and gametophytic differences, both qualitative and quantitative, that allow for a precise distinction between them and they are reinstated here as distinct species. The morphological features that best differentiate U. luteola and U. pygmaeothecia are discussed and illustrated with light microscope and SEM pictures. Finally, an updated and detailed description of each species is presented.

A Site

The Late Cretaceous dinosaur record in southern South America has been improved recently; particularly with findings from Chorrillo and Cerro Fortaleza formations, both bearing ankylosaur remains, a clade that was not previously recorded in the Austral Basin. The dinosaur fauna of the type locality of Cerro Fortaleza Formation is known from -and biased to- large-sized sauropod remains and a single described taxon, the titanosaur Dreadnoughtus schrani. Here, we report the taxonomic composition of a site preserving thirteen isolated teeth and several osteoderms belonging to three dinosaur clades (Abelisauridae, Titanosauria, and Nodosauridae), and at least one clade of notosuchian crocodyliforms (Peirosauridae). They come from sediments positioned at the mid-section of the Cerro Fortaleza Formation, which is Campanian-Maastrichtian in age, adding valuable information to the abundance and biodiversity of this Cretaceous ecosystem. Since non-titanosaur dinosaur bones are almost absent in the locality, the teeth presented here provide a window onto the archosaur biodiversity of the Late Cretaceous in southern Patagonia. The nodosaurid tooth and small armor ossicles represent the first record of ankylosaurs for this stratigraphic unit. The peirosaurid material also represents the most austral record of the clade in South America.

Careful Comparison

Zachaenus roseus Cope, 1890, has puzzled systematists working in southern South America. A single individual, the holotype, has ever been collected and this specimen is in extremely poor preservation condition. Herein, the precise location of the type locality of Z. roseus is determined based on a historical review of the literature. Furthermore, following a careful comparison with all species that inhabit the southern austral forest, and that could potentially correspond to Zachaenus roseus, we conclude that this taxon is placed in the synonymy of Eupsophus calcaratus (Günther, 1881).

The male terminalia of a non-type Diathoneura longipennis (Malloch 1926) specimen,collected in Peru, were dissected and analyzed. The aedeagus and associated sclerites were found tohave been fixed at a late stage of protrusion, resulting in a different morphology, when compared to thetwo previous publications, which were fixed at earlier stages. Consequently, additional details of certainanatomical parts were observed and a better understanding of the aedeagus protruding process was attained.Diathoneura longipennis has been previously identified in San Mateo, Alajuela, Costa Rica (type locality)and Panama, and this specimen represents the first record of this species in South America.
