In this note we report the presence of Beelzebub bee-eater fly Mallophora leschenaulti Macquart, 1938 (Diptera: Asilidae) from northern Chile. A female was collected from highland scrublands in Chapiquiña town, Arica y Parinacota region. In addition, two females are reported from Lluta valley near Peru border. This is the second Mallophora species registered in Chile, distributed in scrubland and cropland ecosystems. We discuss some native carpenter bees and bumblebees as potential preys

Coastal Range

A new species of Scutalus Albers, 1850 (Gastropoda: Bulimulidae), Scutalus chango sp. n., is described from a coastal area of northern Chile. Empty shells of this new species were found buried in sand and under boulders and rocks in the foothills of the Chilean Coastal Range at Paposo, Región de Antofagasta. This new species is distinguished from all other Chilean terrestrial snails by its slender shell with a flared and reflected aperture, and by the presence of a columellar fold. This is the first record of Scutalus in Chile, and the southernmost record for this endemic South American bulimulid genus. The presence of this species in Paposo highlights the need for further research and for conservation guidelines in coastal areas of northern Chile, which have comparatively high levels of biodiversity and endemism.

We report the observation of two juvenile specimens of Sashed Catfish, Galeichthys peruvianus Lütken, 1874, south of Arica, Chile, which expands the current known distributional range of the species, by adding a previously unrecorded locality. The importance of the presence of breeding populations in the northern coast of Chile is discussed.

First Descriptions

Abstract The crustacean communities in Chilean seasonal pools have been poorly studied, and much of the existing literature is restricted to southern Patagonian plains, whereas there are no studies available about other sites. The aim of the present study is to describe the aquatic crustaceans in shallow pools in Huentelauquén (31°S, central northern Chile). The species reported upon include Daphnia ambigua, Simocephalus serrulatus, Boeckella gracilipes, Ostracoda, and two unidentified clam shrimps (genera Lynceus and Leptestheria), which latter ones represent the first record of these taxa for Chile. The ecological results revealed low species numbers and non-structured patterns in the various species associations. The exposed results are markedly different from observations on other Chilean seasonal pools, where no clam shrimps can be found, and where primarily cladocerans, copepods, and amphipods occur in the crustacean communities.

Carpenter Bees

This is the first record of the association between Walkeromya plumipes (Philippi) (Diptera: Bombyliidae) and Xylocopa Latreille (Hymenoptera: Apidae) in Argentina. The pupal development and morphology of Walkeromya plumipes, a parasitoid of Xylocopa splendidula Lepeletier, are described. A parasitized nest was collected from Santiago del Estero province, Argentina. The development of the bombyliid fly and large carpenter bees in the nest were observed in the laboratory for a period of 28 days. A detailed description of the fly adult and pupal stages were carried out. This is the first record of W. plumipes parasitizing X. splendidula. This is also the first complete description of this fly species, including male genitalia. With the data presented here the geographical distribution of the parasite is expanded. The results suggest a close relation between the parasitoid and its host, as the genus Walkeromya Paranov has been found parasitizing only carpenter bees of genus Xylocopa.

Apnea Diving

Melanism in fish is rare; it is expressed in a greater number of limnetic species rather than marine. The capture of a Cheilodactylus variegatus female specimen with full melanosis is reported. The individual was captured with harpoon by apnea diving, in the Caleta Piedra Azul, northern Chile. Its standard length was 33.6 cm and a total weight of 960 g. There is no morphological difference if compared with normal color specimens. The general coloration of the body is dark gray, with slightly lighter vertical stripes on the flank. No fins show the orange hue characteristic of the species. The validity of trematode infection effect as a causal agent of melanosis is discussed, because it is a mutation in the melanocortin receptor (MC1R). The melanosis condition in Ch. variegatus, is very rare. It is the first time that this phenomenon is reported for this species, where the expression of a dark color, would be beneficial to specimens who reside on bottoms with little vegetation and among crevices.

The adult stage of the plume moth Adaina jobimisp. nov. (Lepidoptera: Pterophoridae: Pterophorinae: Oidaematophorini) from the arid highlands of the western slopes of the Andes of northern Chile is described and illustrated. The wing pattern and genitalia of A. jobimi resemble those of A. excreta Meyrick, 1930, from Argentina, Ecuador and Peru and A. coquimboae Gielis, 2012, the only representative of the genus previously known from Chile. Morphological differences of A. jobimi with these two congenerics are discussed. Larval feeding and pupation of A. jobimi occur on inflorescences of the native shrub Baccharis alnifolia Meyen & Walp. (Asteraceae). The discovery of A. jobimi provides the first record of the genus in a long distribution gap in mainland South America west of the Andes Range, suggesting that the taxonomic diversity of Adaina in this area deserves further attention.

Triepeolus cecilyae Packer, new species, and Doeringiella mamabee Packer, new species, both from the far north of Chile are described and illustrated.  Both are known from single male specimens despite considerable search effort in the area of their provenance.  The former species is the first of the genus recorded from Chile.  A key to the three species of Doeringiella Holmberg known from Chile is provided.  Caupolicana dimidiata Herbst is recorded as a likely host of D. gigas (Spinola).
