ASPECTS OF GEODIVERSITY IN THE WEST OF ACRE STATE - BRAZIL

Geodiversity is associated with aspects of geoconservation, natural geological and hydrogeomorphological heritage in each morphoclimatic domain in Brazil. In the Amazon domain, such aspects have been forged in an environment of sedimentary origin since the Cretaceous, identified in the Rio Branco, Juruá-Mirim, Moa and Jaquirana mountains, composed predominantly of sandstones and siltstones. The Serra do Divisor National Park (PNSD) is located in the state of Acre, on the border with Peru and the Andes mountain range. The region has a natural heritage and a geological-geomorphological structure, where waterfalls, caves, valleys and high hills are found, endogenous to the site. The general objective of this article is to present elements of the Geodiversity of the Serra do Divisor National Park (PNSD) focused on the category of geotourism aiming at dissemination at regional, national and international levels.

Sequences of Endophytic Fungal and Bacterial Communities from Araucaria araucana [(Molina) K. Koch, 1869] in the Coastal and Andes Mountain Ranges, Chile

ABSTRACT Here, we report the results from PCR and sequencing of bacterial 16S rRNA and fungal internal transcribed spacer 1 (ITS1) genes from needle, branch, trunk, and root samples of Araucaria araucana, plus soil and associated insects, collected along the entirety of its geographic distribution in Chile (January 2017 and 2018).

First records of ectoparasitic insects (Diptera: Hippoboscoidea) of bats in the department of Caldas, Colombia

In Colombia, the taxonomical understanding of ectoparasites (Diptera: Streblidae and Nycteribiidae) of bats is scarce, despite the high diversity of hosts. This fact reflects the lack of important information on the group and poses the need for studies that expand the knowledge on bat ectoparasites in different regions of the country. The aim of this study was to contribute pioneer knowledge on bat ectoparasitic insects in the department of Caldas, located in the Central Andes Mountain range of Colombia. We assessed 318 bats from four eco parks in the city of Manizales, and collected 234 ectoparasitic insects. We provide the first report of the family Streblidae for Caldas, with seven genera and eight species: Anastrebla caudiferae Wenzel, 1976, Anatrichobius scorzai Wenzel, 1966, Exastinion oculatum Wenzel, 1976, Megistopoda proxima (Séguy‚ 1926), Paratrichobius longicrus Ribeiro, 1907, Paraeuctenodes similis Wenzel, 1976, Trichobius longipes Rudow, 1871, and Trichobius tiptoni Wenzel, 1976. In addition, we report the species Basilia ferrisi Schuurmans Stekhoven, 1931 and Basilia sp. for the family Nycteribiidae.

Parochodaeus bituberculatus (Erichson) (Coleoptera: Ochodaeidae) and Faargia gentilii (Martínez) (Coleoptera: Scarabaeidae), two species newly discovered in Chile

The presence in Chile of scarab beetles (Coleoptera: Scarabaeoidea) described originally from Peru and Argentina have been reported previously, as a result of the distributional corridors through passes in the Andes Mountains (Gutiérrez 1947, 1950; Roig-Juñent et al. 2005; Ruiz-Manzanos 2006; Mondaca 2011). The purpose of this paper is to report the presence of Parochodaeus bituberculatus (Erichson, 1847) (Coleoptera: Ochodaeidae: Ochodaeinae: Ochodaeini) and Faargia gentilii (Martínez, 1975) (Coleoptera: Scarabaeidae: Melolonthinae: Tanyproctini) in Chile, expanding the distribution of the second species to the west of the Andes Mountain range. The presence of both species in Chile is not surprising, due to the similarity of habitats in the collection areas with neighboring localities in Peru and Argentina.

Astatometopon sakakibarai gen. & sp. nov., a montane planthopper from Chile (Hemiptera: Fulgoroidea: Delphacidae)

Astatometopon gen. nov. is described to accommodate A. sakakibarai sp. nov., a delphacid planthopper distributed in the Nahuelbuta and Andes mountain ranges in the central and south central zones of Chile. The new taxon is placed into Delphacini but it presents some unusual features for the tribe, such as a strongly asymmetrical phallus with a porrect process arising from base, the absence of teeth on the hind margin of calcar, and an exceptional variation in carination of the eumetope.
