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.

The largest number of species of the widespread and highly diverse micromoth genus Ypsolopha Latreille, 1796 (Lepidoptera, Yponomeutoidea, Ypsolophidae) is known from the Northern Hemisphere. Only seven species have been described from the Neotropical Region, two of which occur in Chile. The adult stage of Ypsolopha chicoi sp. n. from the arid highlands of the western slopes of the Andes of northern Chile is described and illustrated. Its larvae feed on the native shrub Muehlenbeckia fruticulosa (Walp.) Standl. (Polygonaceae). The morphology of the genitalia of Y. chicoi sp. n. resembles that of the only congeneric known to occur in the same geographic area, Y. moltenii Vargas, 2018, whose larvae feed on Adesmia verrucosa Meyen (Fabaceae). Besides using different host plants, the two species can be accurately separated, based on morphological differences in female and male genitalia.

Iridopsis Warren, 1894 (Lepidoptera: Geometridae: Ennominae: Boarmiini) is a New World moth genus mainly diversified in the Neotropical Region. It is represented in Chile by two described species, both from the Atacama Desert. Iridopsis socoromaensis sp. n. (Lepidoptera: Geometridae: Ennominae: Boarmiini) is described and illustrated from the western slopes of the Andes of northern Chile. Its larvae were found feeding on leaves of the Chilean endemic shrub Dalea pennellii (J.F. Macbr.) J.F. Macbr. var. chilensis Barneby (Fabaceae). Morphological differences of I. socoromaensis sp. n. with the two species of the genus previously known from Chile are discussed. A DNA barcode fragment of I. socoromaensis sp. n. showed 93.7-94.3% similarity with the Nearctic I. sanctissima (Barnes & McDunnough, 1917). However, the morphology of the genitalia suggests that these two species are distantly related. The discovery of I. socoromaensis sp. n. highlights the need for additional surveys in underexplored areas to understand better the taxonomic diversity and evolutionary relationships of the mainly Neotropical moth genus Iridopsis.

I report an aberrant record of Hoatzin Opisthocomus hoazin in the Andes of Lara, Venezuela. During field work in July 2011 in the Yacambú National Park, in an area of premontane cloud forest, I observed and photographed an individual of O. hoazin in El Blanquito reservoir. This is the first record of the species in Lara State, and apparently the highest record of the species in northern South America.

The adult stage of Helioandesia tarregai gen. et sp. nov. (Lepidoptera: Yponomeutoidea: Heliodinidae) is described and illustrated from the arid western slopes of the Andes of northern Chile. The larvae of H. tarregai gen. et sp. nov. feed as leaf skeletonizers on Mirabilis acuta (Reiche) Heimerl (Nyctaginaceae). The mostly gray forewing of H. tarregai gen. et sp. nov., ornamented with strongly bulging metallic spots, resembles that of the representatives of the mainly Nearctic Lithariapteryx Chambers, 1876. However, the latter lacks CuP in the forewing, has a single bristle in the female frenulum, and lacks a well-developed cornutus. Helioandesia gen. nov. clustered as sister to Neoheliodines Hsu, 2004 in a cladistic analysis, although no synapomorphies were found for this cluster, while Lithariapteryx was sister to Helioandesia gen. nov. + Neoheliodines based on two synapomorphies. The genetic distance between a DNA barcode sequence of H. tarregai gen. et sp. nov. and representatives of other genera of Heliodinidae Heinemann, 1877 was 9.0–12.5% (K2P), and a maximum likelihood analysis based on this molecular marker confirmed the placement of H. tarregai gen. et sp. nov. as a member of this micromoth family. This contribution represents the first confirmed record of Heliodinidae for Chile.

The aim of this paper is to evaluate the taxonomic diversity of fossil and extant bats from the region of the Serra da Mesa in the State of Goias, Central Brazil. Quaternary fossils were obtained from four limestone caves, namely Igrejinha, Carneiro, Nossa Senhora Aparecida, and Itambé. Information on extant bat fauna used for comparison were obtained from literature and from the collection of Museu Nacional (Rio de Janeiro). The taxonomic identification of the fragments was based on a comparative study of the masticatory apparatus of extant and fossil bat species. A total of 430 fragments were identified, comprising 27 species: Anoura geoffroyi, Artibeus sp., Carollia sp., Chrotopterus auritus, Desmodus rotundus, Desmodus sp., Emballonuridae sp. indet., Eptesicus/ Histiotus, Glossophaga sp., Lionycteris spurrelli, Lonchorhina aurita, Micronycteris megalotis, Mimon bennetti, Mimon crenulatum, Molossidae sp. indet., Myotis sp., Natalus stramineus, Phylloderma sp. n., Phyllostomus discolor, Phyllostomus hastatus, Platyrrhinus sp., Pteronotus davyi, Pteronotus parnelli, Sturnira sp., Tonatia sp. n., Lophostoma silvicola, and Trachops cirrhosus. Phyllostomidae was the most speciose family, but surprisingly most of the fossil fragments were attributed to the families Natalidae and Mormoopidae. Both of which are rare in the area today. The population reduction of these hot-humid-cave dwelling species (Natalus and Pteronotus) may suggest the climate of the area was warmer and wetter during some interval of the Late Pleistocene or Early Holocene. This study presents the first record of the genera Lionycteris, Lonchorhina and Trachops from the Quaternary of South America. The diversity of Chiroptera found in Serra da Mesa is equivalent to that described for Bahia, which heretofore has the most abundant record for Quaternary bats from South America.

Crocidosema nitsugaisp. nov. (Lepidoptera, Tortricidae, Olethreutinae, Eucosmini) is described and illustrated from the Andes of northern Chile based on adults obtained from larvae collected on leaves, flowers and unripe fruits and seeds of Lupinus oreophilus Phil. (Fabaceae). This represents the first record of insect herbivory on this Chilean endemic perennial herb. The genitalia morphology of C. nitsugai suggests a close evolutionary relationship with two congenerics from high elevation environments of the Ecuadorian and Peruvian Andes.

African Genus

Laccornellus, new genus, is proposed for two austral South American species previously assigned to Laccornis Gozis (L. lugubris (Aube, 1838), the type species, known from Argentina and Uruguay, and L. copelatoides (Sharp, 1882), known from Chile). The valvifer is absent in the adult stage of females of these species and the males have a greatly enlarged internal sac on the aedeagus; these characters exclude them from Laccornis. The most similar and possibly most closely related genus to Laccornellus is the African genus Canthyporus Zimmermann, although no conclusive synapotypy was found. Relationships of extant, plesiotypic hydroporines remain problematic; however, divergence of Laccornellus and Canthyporus probably began about 120 million years ago when Africa and South America separated. The vicariant event preceding divergence of L. copelatoides and L. lugubris probably was the uplift of the Andes Mountains which began in the late Oligocene – early Miocene.

Proclossiana Eunomia

The Proclossiana eunomia (Esper, 1799) complex is currently composed of the several subspecies distributed throughout Palaearсtic region and North America. Despite the fact that some of the taxa have differences in wing pattern and body size, previous assumptions on taxonomy not supported by molecular data. Therefore, the identity of certain populations of this complex has remained unclear and the taxonomic status of several recently described taxa is debated. Here, we provide insights into systematics of some Palaearctic members of this group using molecular approach, based on the analysis of the barcoding fragment of the COI gene taking into account known morphological differences.

The male terminalia of a non-type Diathoneura longipennis (Malloch 1926) specimen,collected in Peru, were dissected and analyzed. The aedeagus and associated sclerites were found tohave been fixed at a late stage of protrusion, resulting in a different morphology, when compared to thetwo previous publications, which were fixed at earlier stages. Consequently, additional details of certainanatomical parts were observed and a better understanding of the aedeagus protruding process was attained.Diathoneura longipennis has been previously identified in San Mateo, Alajuela, Costa Rica (type locality)and Panama, and this specimen represents the first record of this species in South America.
