RESUMO

Abstract Cercophana frauenfeldii Felder (Lepidoptera: Saturniidae), also known as the "Andean Moon Moth", is a Neotropical species native to continental Chile whose larvae feed on species of the families Gomortegaceae, Laureaceae and Winteraceae. We describe and document C. frauenfeldii immature stages, namely, egg, its four larval instars, and chaetotaxy of the last instar, pupa and cocoon for the first time. In terms of its phenology, we extend its larval activity, originally described to occur between November and mid-December, to June until the end of January. We report the adult flight period depends on the species' distributional range following two well-differentiated patterns: February to mid-April in Central-North Chile and April to June in Central-South Chile. Furthermore, we provide a unified view of its current distributional range and host plants (including the endangered tree Gomortega keule) through bibliographic data, field observations and laboratory rearing. Finally, we discuss aspects of the species' conservation as part of the unique ecosystems found in the temperate forests of southern South-America.

RESUMO

ABSTRACT Glena mielkei Vargas, 2010 (Lepidoptera: Geometridae: Ennominae: Boarmiini) is a Neotropical geometrid moth native to the Atacama Desert of northern Chile whose larvae are folivorous on the shrub Trixis cacalioides (Asteraecae). The last instar and pupa are described and illustrated, and DNA barcode sequences are provided for the first time for G. mielkei. Descriptions are made based on larvae collected in the type locality. Comparisons with the available descriptions of congeneric species suggest that the chaetotaxy of the SV group of the abdominal segment and the morphology of the cremaster could be useful tools to species identification based on last instar and pupa, respectively. A search in BOLD (Barcode of Life Data System) showed that the only DNA barcode haplotype found in the two specimens sequenced was closest to Physocleora Warren, 1897 than Glena Hulst, 1896. These results coincide with the morphological peculiarities of the genitalia highlighted in the original description of G. mielkei, suggesting that a definitive assessment of the generic status of this geometrid moth deserves further integrative studies.

RESUMO

Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert. The spatial distribution of the immature stages of the leaf miner Angelabella tecomae Vargas & Parra, 2005 was determined at two intra-plant levels (shoot and leaflet) on the shrub Tecoma fulva fulva (Cav.) D. Don (Bignoniaceae) in the Azapa valley, northern Chilean Atacama Desert. An aggregated spatial pattern was detected for all the immature stages along the shoot, with an age dependent relative position: eggs and first instar larvae were clumped at apex; second, third and fourth instar larvae were mostly found at intermediate positions; meanwhile the spinning larva and pupa were clumped at basis. This pattern suggests that the females select new, actively growing leaflets for egg laying. At the leaflet level, the immature stages were found more frequently at underside. Furthermore, survivorship was higher for larvae from underside mines. All these results highlight the importance of an accurate selection of egg laying site in the life history of this highly specialized leaf miner. By contrast, eventual wrong choices in the egg laying site selection may be associated with diminished larval survivorship. The importance of the continuous availability of new plant tissue in this highly human modified arid environment is discussed in relation with the observed patterns.

RESUMO

Observations on the biology and distribution of Uresiphita reversalis (Lepidoptera, Crambidae), a defoliator of the native tree Calia secundiflora in México. Uresiphita reversalis (Guenée, 1854) feeding on Calia secundiflora (Ortega) Yakovlev is recorded for the first time in the state of Hidalgo, Mexico. New aspects regarding the life cycle, feeding behaviour, geographical distribution and host plant damage by U. reversalis on C. secundiflora are here presented and discussed.

RESUMO

A replacement name for Hualpenia Mundaca, Parra & Vargas (Lepidoptera, Gracillariidae). Vihualpenia nom. nov. is proposed as a replacement name for Hualpenia Mundaca, Parra & Vargas, 2013 (Lepidoptera, Gracillariidae), in order to remove homonymy with Hualpenia Franz, 1996 (Coleoptera, Staphylinidae).

RESUMO

A new genus and species of leaf miner (Lepidoptera, Gracillariidae) for Chile associated to the native tree Lithraea caustica. We propose the new genus and species of Gracillariidae (Lepidoptera) Hualpenia lithraeophaga Mundaca, Parra &Vargas gen. nov., sp. nov., leaf miner of Lithraea caustica (Mol.) H. et Arn (Anacardiaceae) occurring in southern central Chile. Aspects of the life cycle, adult and larval morphology, development and feeding habits of the new genus and species are also presented. We emphasise the uniqueness and importance of this new species for broadening the current knowledge on the Chilean fauna of Gracillariidae.

RESUMO

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.


Primeiras observações sobre a biologia da nidificação de Hypodynerus andeus (Packard) (Hymenoptera, Vespidae, Eumeninae) no vale de Azapa, norte do Chile. Alguns aspectos da biologia da nidificação da vespa Hypodynerus andeus (Packard, 1869) são registrados pela primeira vez. As observações foram conduzidas no vale de Azapa, deserto litoral do norte do Chile. Sessenta ninhos foram coletados e examinados, cada um composto por 1-14 células. A maioria dos ninhos estava aderida a postes de concreto. As únicas presas registradas nas células foram larvas de Geometridae (Lepidoptera). Um parasitóide, Anthrax sp. (Diptera, Bombyliidae), foi também registrado. Vários artrópodes, principalmente aranhas, foram encontrados utilizando ninhos vazios.
