Abstract Plecturocebus caquetensis (Defler, Bueno, and García, 2010) is a Neotropical primate commonly called the Caquetá titi monkey. It is small-sized with long, soft pelage of mixed coloration including grayish and buffy brown to agouti tones. It lacks the blackish or whitish band that is present on the forehead of closely related species. The tail is agouti-colored and slightly banded at its base. Endemic to the Amazonian region of Colombia with a distribution in areas near the eastern slopes of the Eastern and Central Cordillera of the Andes, P. caquetensis is confirmed in 104 localities in the departments of Cauca and Caquetá in Colombia. P. caquetensis is considered “Critically Endangered” (CR) by the International Union for Conservation of Nature and Natural Resources.

Morphological Differences

I describe Athyrium bipinnatumsp. nov. and discuss morphological differences between closely related species. The new species is endemic to Japan, occurring on the islands of Honshu, Kyushu, and Shikoku. Based on the criteria of the International union for conservation of nature and natural resources, this new species is here considered endangered.

A New Species

Angraecum jeannineanum, a new species endemic to Mauritius, is described and its ecology and conservation status are discussed. Angraecum jeannineanum differs from A. cadetii, which is the morphologically most closely related species, as follows: (i) leaves are smaller, thicker and darker green, (ii) inflorescences and flowers are thinner and smaller, (iii) flowers are more greenish and non-fleshy. Angraecum jeannineanum belongs to Angraecum section Hadrangis, endemic to the Mascarenes, which also includes A. bracteosum, A. cadetii and A. striatum. An updated key for the section is provided. The species should be considered as Critically Endangered (CR) according to the Red List Criteria of the International Union for the Conservation of Nature (IUCN). This assessment is based on the highly restricted species distribution, small population size, and habitat sustaining degradation by invasive alien plants and animals.

ABSTRACT On the basis of morphology Chenopodium quinoa of the Andes and C. nuttalliae of Mexico appear to be very closely related species. Artificial hybrids have been secured between the two. It is suggested that both species may have been derived from the same original wild type. A weedy quinoa, C. quinoa var. melanospermum, is known from South America, but as yet a weed race closely related to C. nutalliae has not been reported from Mexico.

Diuris fragrantissima D. L. Jones et M. A. Clem. is a perennial terrestrial orchid endemic to the state of Victoria, Australia. The species is listed as Critically Endangered in Victoria under the criteria of the International Union for the Conservation of Nature and Natural Resources (IUCN), having suf- fered a severe population decline since the 1930s, largely attributable to habitat destruction for agricul- tural and urban development.

Kelapa sawit adalah salah satu komoditas perkebunan yang berkembang pesat di Indonesia, dengan total luas lahan perkebunan seluas 11.672.861 ha pada tahun 2016. Pembukaan lahan perkebunan kelapa sawit seringkali dilakukan dengan mengalihkan fungsi lahan hutan menjadi lahan perkebunan, hingga menimbulkan berbagai dampak, mulai deforestasi hingga menjadi ancaman serius bagi keanekaragaman hayati di Indonesia, tidak terkecuali orangutan. Orangutan adalah salah satu satwa endemik indonesia yang hanya dapat ditemukan di pulau Kalimantan dan pulau Sumatera turut mengalami kerusakan habitat dan penurunan angka populasi. Berdasarkan Assessment Information yang dikeluarkan oleh IUCN (International Union for Conservation of Nature and Natural Resources) orangutan menyandang status konservasi Critically  endangered pada tahun 2016. Dalam rangka perlindungan habitat orangutan di Indonesia, pembukaan lahan perkebunan kelapa sawit tunduk pada instrumen yang diatur dalam Undang-Undang Nomor 32 Tahun 2009 tentang Perlindungan dan Pengelolaan Lingkungan Hidup dan dalam prinsip-prinsip yang diatur dalam Peraturan Menteri Pertanian Nomor 19 Tahun 2011 tentang Pedoman perkebunan Kelapa Sawit Berkelanjutan Indonesia.

Abstract Aegialomys galapagoensis (Waterhouse, 1839) is a sigmodontine rodent commonly called the Galapagos rice rat. It is a medium-sized rodent, characterized by dense, soft, yellow or copper, weakly grizzled pelage; the dorsum is grayish or brownish and the ventral pelage is pale. It is endemic to the open habitats of the Galapagos Archipelago, occurring on three islands, Santa Fé Island (Barrington Island), San Cristóbal Island (Chatham Island), and Santiago Island (James Island). Restricted populations are considered a major threat to A. galapagoensis conservation throughout most of its range, as well as competition with Rattus rattus. A. galapagoensis is listed as “Vulnerable” by the International Union for Conservation of Nature and Natural Resources, and is listed as “Critically Endangered” on the Ecuador National list.

Abstract Dasypus kappleri Krauss, 1862, commonly known as greater long-nosed armadillo, is the second largest extant armadillo and readily distinguishable by the prominent spurs on the hind legs. It is diurnal-nocturnal, solitary, and insectivorous. It is a semi-fossorial species ranging east of the Andes across the central lowlands of South America. It occupies a wide range of habitats including rainforest, riparian forest, and grassland. D. kappleri is listed as “Least Concern” by the International Union for Conservation of Nature and Natural Resources in light of its wide distribution, which presumedly contains robust populations.

Abstract Platalina genovensium Thomas, 1928 is a bat commonly called Peruvian long-tongued bat. P. genovensium is characterized by having a greatly elongated muzzle, rostrum clearly longer than the braincase, and premaxillary bones projecting beyond the canines. The dorsal pelage is long and bicolored; the venter is lighter than the dorsum. P. genovensium is distributed from west of the Andes in Peru to northern Chile, with a few records reported from the Andes in Peru. It feeds in desert areas characterized by the presence of columnar cacti from which it obtains nectar and fruits; it has been recorded at elevations from near sea level up to about 2,600 m. It is listed as “Near Threatened” by the International Union for Conservation of Nature and Natural Resources.

In this study, we describe the ferns Diplazium × kanayamaense hyb. nov. and D. × tsukushiense hyb. nov. and further compare them to parental species D. chinense, D. deciduum and D. fauriei in terms of morphological characteristics, plastids and nuclear DNA markers. These new hybrids have been determined to be endemic to western Japan. The International Union for Conservation of Nature and Natural Resources status was evaluated for D. × kanayamaense as endangered (EN) and D. × tsukushiense as critically endangered (CR).
