The molluscan fauna of southwestern Brazilian Amazonia is poorly known due to the lack of focused collection areas in the region since the early 20th century. The present study provides an inventory of the terrestrial gastropods from a forest fragment in the eastern Acre state, Brazil: the Humaitá Forest Reserve (“Reserva Florestal Humaitá”). Live specimens and empty shells were collected between August 2018 and January 2019. A total of 20 species were identified, distributed in 11 families. Most (13) of these species were recorded in Acre for the first time. Furthermore, we confirm the occurrence of Systrophia helicycloides (d’Orbigny, 1835) in Brazil, reiterate the synonymy of Plekocheilus pentadinus (d’Orbigny, 1835) with P. floccosus (Spix in Wagner, 1827), and synonymize Solaropsis peruviana Haas, 1951 with S. juruana Ihering, 1905.

Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the aerial parts and the resin. The experiment to stimulate the exudation of resin from the trunk was conducted using a 2-chloroethylphosphonic acid solution. The resin produced after 40 days and the aerial parts had their essential oils extracted in a Clevenger apparatus and the volatile chemical constituents were analyzed using GC/MS. The non-oxygenated sesquiterpenes α-copaene (21.15%) and α-gurjunene (13.69%), in addition to the oxygenated sesquiterpene spathulenol (10.32%), were detected as the majority constituents of the essential oil of the leaves, and a concentration similar to that of α-gurjunene was found in the branches (13.28%). The resin essential oil showed a high concentration of hydrocarbon monoterpenes (76.49%) with a predominance of α-pinene (17.57%) and limonene (46.11%). Four gall morphotypes were found associated with this species. The present study reports for the first time information on the volatile constituents and the resinous potential of P. aracouchini, and registers the morphotypes of the galls that help in the taxonomy of the species.

A New Species

Macrostemum is the second largest genus of Macronematinae with about 104 described species distributed in the Neotropical (18), Afrotropical (20), Australasian (7), Palearctic (2), Nearctic (3) and Oriental (54) regions. Despite its great diversity, knowledge about its immature stages is scarce: worldwide, only 7 species (6.7%) have larvae and/or pupae described. From the Neotropics, only one species, Macrostemum ulmeri (Banks, 1913), has described larvae and pupae. The objectives of this study are to describe and illustrate a new species, Macrostemum araca sp. nov., based on adult males and females from Serra do Aracá, Amazonas, Brazil, and the larvae and pupae of M. brasiliense (Fischer, 1970) from an Atlantic Forest fragment in São Paulo state using the metamorphotype method. In addition, this species is recorded for the first time for Minas Gerais state.

Pristine Forest

The ant fauna of state of Acre, Brazilian Amazon, is poorly known. The aim of this study was to compile the species sampled in different areas in the State of Acre. An inventory was carried out in pristine forest in the municipality of Xapuri. This list was complemented with the information of a previous inventory carried out in a forest fragment in the municipality of Senador Guiomard and with a list of species deposited at the Entomological Collection of National Institute of Amazonian Research– INPA. The resulting list covered 268 species distributed in 52 genera and nine subfamilies, and records 23 species and four morphospecies for the first time in the state of Acre. Due to the large environmental heterogeneity, future inventories will be crucial to properly describe and understand ant species distribution patterns in southwestern Amazon.

This study aimed to expand knowledge about tick parasitism on wild birds in western Amazonia and provide additional records of species parasitized by ticks in the state of Acre. Birds were captured with mist nets from September 2016 to February 2017 at the Fazenda Experimental Catuaba, in Senador Guiomard, Acre State, Brazil, identified, and thoroughly inspected. Detected ticks were removed with tweezers, stored in labeled collectors containing 70% alcohol, and identified using a stereomicroscope with incident lighting and taxonomic keys at the Department of Preventive Veterinary Medicine and Animal Health of the School of Veterinary Medicine and Animal Science of the University of São Paulo. In total, 203 wild birds were captured, comprising nine orders and 24 families. Among them, 24 birds (11.82%) belonging to 13 species were parasitized by 44 ticks at different stages: 26 Amblyomma sp. larvae, 10 Amblyomma nodosum nymphs, four Amblyomma longirostre nymphs, and four Amblyomma humerale nymphs. This study reports for the first time nine new species of birds as hosts of ticks of the genus Amblyomma in the state of Acre, namely: Monasa nigrifrons, Hypocnemis subflava, Dendrocincla fuliginosa, Sittasomus griseicapillus, Xiphorhynchus guttatoides, Poecilotriccus latirostris, Hemitriccus flammulatus, Ramphotrigon megacephalum, and Turdus amaurochalinus. This study also records, for the first time, A. nodosum ticks parasitizing R. megacephalum and A. humerale parasitizing Momotus momota, S. griseicapillus, and X. guttatoides.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

AbstractThe present study reports associations between feather mites (Astigmata) and birds in an Atlantic Forest fragment in Rio Grande do Norte state, in Brazil. In the laboratory, mites were collected through visual examination of freshly killed birds. Overall, 172 individuals from 38 bird species were examined, between October 2011 and July 2012. The prevalence of feather mites was 80.8%, corresponding to 139 infested individuals distributed into 30 species and 15 families of hosts. Fifteen feather mite taxa could be identified to the species level, sixteen to the genus level and three to the subfamily level, distributed into the families Analgidae, Proctophyllodidae, Psoroptoididae, Pteronyssidae, Xolalgidae, Trouessartiidae, Falculiferidae and Gabuciniidae. Hitherto unknown associations between feather mites and birds were recorded for eleven taxa identified to the species level, and nine taxa were recorded for the first time in Brazil. The number of new geographic records, as well as the hitherto unknown mite-host associations, supports the high estimates of diversity for feather mites of Brazil and show the need for research to increase knowledge of plumicole mites in the Neotropical region.

The Coleoptera fauna of forensic importance associated with Sus scrofa Linnaeus, 1758 carcass decomposition in Ducke Reserve, Manaus, Brazil, was determined. A total of 41 species, belonging to six families and 11 subfamilies were collected. Staphylinidae presented the higher richness with 17 species sampled, followed by Histeridae, with 11 and Scarabaeidae with nine species. Euspilotus azureus (Sahlberg, 1823) (Histeridae), Aleochara sp. (Staphylinidae) and Oxelytrum cayennense (Stürm, 1826) (Silphidae) occurred in all stages of decomposition. Omalodes lucidus Erichson, 1824 and Scapomegas auritus Marseul, 1855 (Histeridae) are recorded for the first time in the Amazon, being also reported for the first time associated with a decomposing carcass. The fauna differs from those of other Brazilian regions, emphasizing the importance of studies to determine the regional insect fauna of forensic importance that can be used in criminal investigations.

This study aimed to identify parasitoid species of frugivorous larvae and to describe the tritrophic interactions involving wild fruits, frugivorous insects and their natural enemies at Adolpho Ducke Forest Reserve (RFAD) (Manaus, AM, Brazil). Collections were performed in four 1 km² quadrants in the corners of the RFAD. The wild fruits were collected inside the forest in access trails leading to each collection area and in trails that surrounded the quadrants, up to five metres from the trail on each side. The fruits were placed in plastic containers covered with thin fabric, with a vermiculite layer on the base to allow the emergence of flies or parasitoids. Seven Braconidae species were collected, distributed among Opiinae: Doryctobracon areolatus (Szépligeti, 1911), Utetes anastrephae (Viereck, 1913), and Opius sp., and Alysiinae: Asobara anastrephae (Muesebeck, 1958), Phaenocarpa pericarpa Wharton and Carrejo, 1999, Idiasta delicata Papp, 1969, and Asobara sp. Parasitism rates by braconids and figitids are presented. Doryctobracon areolatus was the most frequent, parasitizing the highest number of fly species, and showing the highest parasitism percentage in larvae feeding on Micropholis williamii fruits. The collected figitids belong to Aganaspis nordlanderi Wharton, 1998 and A. pelleranoi (Brethes, 1924). All 15 tritrophic associations are new records for the Brazilian Amazon region. The RFAD is an important natural reservoir of frugivorous larvae parasitoids.

The molluscs of a previously unexplored site the “Ženklavský les” forest in North Moravia (Czech Republic) were investigated in 2002. Altogether 47 snail species were recorded (46 terrestrial and 1 aquatic). The molluscan fauna was dominated by woodland species including sensitive and endangered ones (e.g., Platyla polita, Sphyradium doliolum, Ruthenica filograna, Vitrea subrimata, and Daudebardia brevipes). The species Vertigo pusilla, and Vestia ranojevici moravica were encountered in the Štramberk environs for the first time and are of regional importance.

There are only a few published bat surveys from the southwestern Brazilian Amazon, but recent studies have reported additional bats species in the region. We provide the first list of bat species from Floresta Estadual do Antimary (Antimary State Forest) and record for the first time Glyphonycteris sylvestris Thomas, 1896 and Phylloderma stenops Peters, 1865 in the state of Acre, increasing to 64 the number of species known from this state. Our survey enlarges the known geographic range of G. sylvestris in Brazilian territory and improves the inventory of bat species in a poorly sampled region of the Amazon.
