The remote Nangaritza Valley of southeast Ecuador has high bird diversity, combining Amazonian birds with species typical of eastern Andean slopes and foothills, a small number of taxa endemic to the Cordillera del Cóndor region of southern Ecuador and northern Peru, as well as a few forms from the dry Marañón valley region. Here, we update and review avifaunal records from the Nangaritza Valley, comparing them with the bird fauna of the Cordillera del Kutukú and making a brief assessment of bird conservation in the area. To date, 535 species are known to occur in the Nangaritza Valley, including eight species endemic or near endemic to the outer ridges and adjacent Andean slopes in southeast Ecuador and northeast Peru. Conservation perspectives in the area are not favorable owing to increasing deforestation, expansion of the agricultural frontier and mining concessions, which threaten eight regional endemic species.

Five new species of Penaincisalia (Lycaenidae: Eumaeini) are described from the high Andes of southern Ecuador and northern Peru: P. caeruleanota Hall & Willmott n. sp., P. juliae Hall & Willmott n. sp., P. andreae Busby & Hall n. sp., P. libertada Hall n. sp. and P. ismaeli Busby & Hall n. sp.. We present brief discussions on their systematic placement within the genus and on their adult ecology.

Cinnabar ore is the source of a bright red pigment (mercury [II] sulfide, HGS), a substance that was highly valued in the Central Andes during prehispanic times. It is traditionally believed to come from Huancavelica in south-central Peru, although some scholars have argued that a prehispanic cinnabar source existed at Azogues near Cuenca in southern Ecuador. It has also been suggested that the cinnabar recovered at archaeological sites in northern Peru such as Baton Grande may have come from this putative Ecuadorian source. In this article, the historical and archaeological evidence supporting this position is evaluated and found to be insufficient to sustain the Ecuadorian Cinnabar Hypothesis. Moreover, recent mercury isotope analysis of archaeological samples from northern Peru supports the earlier hypothesis that the source of the bright red pigment, sometimes referred to as vermilion, was cinnabar ore mined in Huancavelica. This source is located over 850 km to the south of archaeological sites such as Batdn Grande, Chongoyape, and Pacopampa.

This paper reviews Hippotis Ruiz & Pav. and Schradera Vahl, two Rubiaceae genera with centers of diversity in western South America. Both are inadequately known and in need of field study. Recent authors’ circumscriptions of H. albiflora H. Karst. and H. mollis Standl. are narrowed here, and four new species of Hippotis are described: H. antioquiana C. M. Taylor from northwestern Colombia, H. ecuatoriana C. M. Taylor from central-southern Ecuador, H. elegantula C. M. Taylor & M. Calderón from the western Amazon basin in Ecuador, and H. vasqueziana C. M. Taylor from lowland northeastern Peru. Four new species of Schradera Vahl are also described here: S. cernua C. M. Taylor and S. francoae C. M. Taylor from western Colombia, S. condorica C. M. Taylor & D. A. Neill from southern Ecuador, and S. morindoides C. M. Taylor from southern Ecuador and northern Peru. Schradera condorica at least sometimes is a free-standing tree, a habit newly documented for this genus.

Abstract Gumuk is one of the important ecosystems in bird conservation in Jember Regency. Currently, many gumuk ecosystems are being degraded, and very rapid land-use change that threatens the preservation and conservation of birds. This study aims to determine the diversity of birds around the gumuk as an effort to explain the important role of the gumuk as a bird habitat. The research was conducted in January-February 2021 in Ledokombo District, Jember Regency. Bird observation method using Point Count method, observation time is in the morning (06.00-08.00 WIB) and afternoon (15.00-17.00 WIB). The results showed that there were 33 species of birds from 20 families. The families of Campephagidae and Estrildidae show the families with the most species found. The level of diversity shows the moderate category (H'=2.253). Species with the highest abundance were Collocalia linchi (31.264%), and the lowest were Amandava amandava, Dicaeum concolor, Geopelia striata, Passer montanus, and Ardeola speciosa (0.044%). Evenness index (E) shows the condition of stable species distribution with a value of 0.644.
