A new species of Glena Hulst (Lepidoptera, Geometridae) from northern Chile

A new species of Glena Hulst (Lepidoptera, Geometridae) from northern Chile. A new species of Glena Hulst (Lepidoptera, Geometridae) is described from two valleys of the coastal desert of northern Chile. Immature stages are associated with Trixis cacalioides (Kunth) Don. (Asteraceae). Holotype, male and female genitalia, and a sexual dimorphic feature are illustrated. This is the first record of a species of Glena from Chile.

A new species of Lioptilodes Zimmerman (Lepidoptera, Pterophoridae) from northern Chile

Male and female adults of a new species of Lioptilodes Zimmerman (Lepidoptera, Pterophoridae) are described and illustrated. Immature stages are associated with Baccharis scandens (Ruiz & Pav.) Pers. (Asteraceae). The species was collected in two localities of northern Chile: near sea level in the Azapa valley, in the coastal desert of Arica Province and at 3000 m elevation in Socoroma, Parinacota Province.

A new species of Eccopsis Zeller (Lepidoptera, Tortricidae) from the coastal valleys of northern Chile, with the first continental record of E. galapagana Razowski & Landry

A new species of Eccopsis Zeller (Lepidoptera, Tortricidae) from the coastal valleys of northern Chile, with the first continental record of E. galapagana Razowski & Landry. Eccopsis Zeller, 1852 is reported for the first time from Chile. Eccopsis razowskii Vargas, n. sp. is described and illustrated based on specimens reared from larvae collected on native Acacia macracantha Willd. (Fabaceae) in the coastal valleys of the northern Chilean desert. Eccopsis galapagana Razowski & Landry, 2008, previously known only from the Galapagos Islands, Ecuador, is recorded for the first time from continental South America. Larvae of the latter were collected in northern Chile feeding on Prosopis alba Griseb (Fabaceae).

A new species of Eupithecia Curtis (Lepidoptera, Geometridae) from the Azapa Valley, northern Chile

A new species of Eupithecia Curtis (Lepidoptera, Geometridae) from the Azapa Valley, northern Chile. Male and female adults of a new species of Eupithecia Curtis from the Arica Province, Chile are described and illustrated. The species is compared with E. yubitzae Vargas & Parra, 2004, from the same locality, and E. galapagosata Landry & Rindge 1995, from the Galapagos Islands, Ecuador.

Termite assemblages in five semideciduous Atlantic Forest fragments in the northern coastland limit of the biome

Termites are abundant organisms in tropical ecosystems and strongly influence the litter decomposition and soil formation. Despite their importance, few studies about their assemblage structures have been made in Brazilian Atlantic Forest fragments, especially in the area located north of the São Francisco River. This study aims to analyze the assemblage composition of five Atlantic Forest fragments located in the northern biome limit along the Brazilian coast. A standardized sampling protocol of termites was applied in each fragment. Thirty-three termite species belonging to twenty genera and three families were found in the forest fragments. The wood-feeder group was dominant both concerning to species richness and number of encounters in all areas. In sites northern to 7°S, there is an evident simplification of the termite assemblage composition regarding species richness and number of encounters by feeding group. This fact is apparently due to a higher sandy level in soils and to semideciduous character of the vegetation in the northern fragments. Thus, even on the north of São Francisco River, termite biodiversity is heterogeneously spread with highest density of species in the portion between 07°S and São Francisco River mouth (10°29'S).

First remarks on the nesting biology of Hypodynerus andeus (Packard) (Hymenoptera, Vespidae, Eumeninae) in the Azapa valley, northern Chile

First remarks on the nesting biology of Hypodynerus andeus (Packard) (Hymenoptera, Vespidae, Eumeninae) in the Azapa valley, northern Chile. Some aspects about the nesting biology of the potter wasp Hypodynerus andeus (Packard, 1869) are reported for the first time. Observations were carried out at the Azapa valley, coastal desert of northern Chile. A total of sixty nests were collected and examined, each composed by 1-14 cells, most of them found attached to concrete lamp posts. The only preys recorded in the cells were Geometridae (Lepidoptera) caterpillars and the presence of the parasitoid Anthrax sp. (Diptera, Bombyliidae) was also recorded. A number of arthropods belonging to different groups, mainly spiders, were found occupying empty nests.
