The Common

Pygicera Kerremans, 1903 is an endemic genus of jewel beetle of Chile distributed in the central Chile hotspot, which is distributed from the Atacama Desert in the north to the Valdivian Forest in the south (Myers et al., 2000). Currently, Pygicera is composed of one species and two subspecies: Pygicera scripta scripta Laporte & Gory, 1837 and the Valdivian rainforest subspecies Pygicera scripta krahmeri Moore 1981 (Figs 2–6). The first subspecies is distributed from Limarí in the Coquimbo Region to Curicó in the Maule Region, both in the coast as well as Andean foothills. This is considered the common subspecies (Moore, 1981; Moore & Vidal, 2015). The southern subspecies is distributed from Victoria in the Araucanía Region to La Unión in Los Ríos Region (Moore, 1981; Moore & Vidal, 2015) and is the rarest and less abundant subspecies. The larvae of both subspecies have been recorded in the “maitén” (Maytenus boaria) Molina, from which they have been reared (Moore, 1981, 1987; Moore & Vidal, 2015).

A New Species

A new species, Trirammatus torqueotrochantus is described from Caram vida, Chile. Males of this species are distinguished by unique femur-length, twisted and falcate trochanters, which are a form unlike that of any described pterostichine. Both sexes are recognizable from other species of Trirammatus by the combination of short metepisternum and bicolored legs. The species is included in Trirammatus based on the shared condition of having paired sub-tarsal claw setae. The status and characters of genera thought to be near relatives of Trirammatus, the evolution of elongate metatrochanters and their relationship to wedge-pushing are briefly discussed. The hind legs of T. torqueotrochantus, Pterostichus (Cylindrocharis) acutipes acutipes, P. (Steropus) moestus and Acanthoferonia ferox are illustrated to show relative trochanter lengths.

Sarcophagid flies belonging to the subfamily Miltogramminae are mainly kleptoparasites of bees and solitary wasps. Twenty-six locations were surveyed to accomplish the first specific exploration on the diversity of Miltogramminae in southern Andean areas of South America. We evaluated changes in abundance, richness and composition among habitat types to establish the effect of anthropization on the Miltogramminae community. Habitat types were considered as human modified (trails and roads, parks and meadows) and natural sites (watercourses and lake beaches, sandy and shrubby areas), distributed in two ecoregions (Valdivian forest and Patagonian steppe). We found differences in the capture rate and composition of Miltogramminae among habitat types. The species Opsidia intonsa Aldrich was highly dominant in samples, with higher proportional abundance in human modified habitats. Richness of Miltogramminae was higher in natural sites. Comparisons between the ecoregions surveyed indicated the genus Opsidia Coquillett did not show differences in abundance between ecoregions, whereas Senotainia Macquart was more abundant in the Patagonian steppe. The results provide evidence on the significant effects of human influence on landscapes in kleptoparasitic fly diversity. Slight modifications of natural areas (as proliferation of trails or isolated houses) should be addressed to evaluate the conservation of kleptoparasitic Diptera.

Mite Genus

The genus Eutegaeus (Oribatida, Eutegaeidae) comprises 13 species, which are distributed in the Australian, Neotropical and Antarctic regions; of these, two new species are described from litter in the relictual Valdivian forest of Chile. Eutegaeus parapapuaensis sp. nov. (description based on the adult and tritonymph) differs from Eutegaeus papuensis Aoki, 1964 by the absence of translamella, interbothridial tubercles, notogastral setae h3 and epimeral setae 3a. Eutegaeus paralagrecai sp. nov. (description based on the adult and proto-, deuto- and tritonymph) differs from Eutegaeus lagrecai Arcidiacono, 1993 by the presence of lanceolate bothridial setae and long notogastral setae p1, and the absence of striate ornamentation on the notogaster. A revised generic diagnosis and an identification key to known species of Eutegaeus are presented. Nymphs of Eutegaeus and related genera in Eutegaeoidea are compared.

Cape Horn

By southern Chile I mean a strip of land more than 2000 kilometres long, beginning at its northern end with the Valdivian forest at the 36th parallel and ending at Cape Horn at the 56th parallel. Because of the zone’s extreme dissection and the very low density of population this is a very difficult area in which to travel and it is the least well explored part of Chile. Certain important and extensive areas have faunas which are virtually unknown; we may instance those between Puerto Montt and Aisen and also the whole of the coastal strip of Aisen as well as the islands between Chiloe and the Gulf of Penas. Owing to the fact that something is known of both ends of the zone it is possible to form a general idea of the characteristics and composition of the included fauna.

Mite Family

The oribatid mite family Camisiidae is commonly recognized to include four genera and about 100 nominal species, all of which appear to be asexual. Based on adult specimens from Valdivian forest litter in Osorno Province, Chile, we propose a monotypic fifth genus, Paracamisia gen. n., with type species P. osornensis sp. n. This is the first genus of the family that is not represented in the Northern Hemisphere. Like all other known Camisiidae it seems to be asexual. Paracamisia osornensis sp. n. is distinguishable from other camisiids by its shiny, convex notogaster that lacks a suprapleural scissure, and by its large respiratory bothridial saccule. A preliminary analysis suggests that its closest relatives are to be found in the genus Platynothrus.

We provide a map of the 15 biogeographic provinces of Argentina based on the ecoregions recognized for the country, combining climatic, geological and biotic criteria. Argentinean provinces belong to the Neotropical region (Yungas, Paraná Forest, Araucaria Forest, Chaco and Pampean provinces), the South American transition zone (Puna, Monte, Comechingones and Cuyan High Andean provinces) and the Andean region (Patagonian, Maule, Valdivian Forest, Magellanic Forest, Falkland Islands and Magellanic Moorland provinces). In order to facilitate future biogeographic analyses, we provide a file of this biogeographical regionalisation in vector format using the World Geodetic Survey 1984.
