ABSTRACT We report on the discovery of a population related to the Blunt-headed Salamander (Ambystoma amblycephalum), a micro-endemic axolotl from Mexico scientifically confirmed only once since its original description in 1940, and now presumably extinct. In 2018, paedomorphic and metamorphosed adults, as well as clutches and larvae, were found in a cattle pond at Nahuatzen, Michoacán state, Mexico, ~60 km away from the type locality (Tacícuaro). Morphometric comparisons suggested high similarity with the type series of A. amblycephalum, while mitochondrial DNA barcoding (16S and control region) revealed close (but imperfect) matching to a reference sequence. We gathered data on life history and ecology of this population, which could be the only extant relic of A. amblycephalum. Its highly limited distribution and presumably low population density are hallmarks for a high risk of extinction, and alarms on the critical situation of many micro-endemic salamanders of Mexico, hence calling for immediate conservation actions.

ABSTRACT To determine the diet of Erythrolamprus aesculapii we reviewed 15 literature sources and make a list of preys registered in Ecuador and South America. In addition, we reported the consumption of an additional species in the list. We identified a total of 40 prey item, 36 (90%) of them are ophidians (34 colubrids and one elapid). E. aesculapii could be considered as an ophiophagous species.

ABSTRACT The Rose-ringed parakeet (Psittacula krameri), native to India, South Asia, and Sub-Saharan Africa, is considered one of the most invasive bird species. It has been recorded in 37 countries, in some of which it was originally introduced as a pet. It has become an agricultural pest and a threat to native birds in many countries. In South America, populations of this species were only known to exist in Venezuela and the Caribbean Islands. We report the finding of a small reproductive population of Rose-ringed parakeets in the city of Corrientes, in northeastern Argentina. We provide information on its observed feeding patterns and interactions with two other species of birds. We suggest monitoring the species and its population trends, as well as starting an awareness campaign of the dangers to native fauna posed by invasive alien species.

ABSTRACT Breeding in colonies is a defining characteristic of many waterbird species and several behavioural and habitat traits determine nest-site selection. Although there is relatively extensive literature on the topic, information on the within-colony distribution of nests lacks for mixed colonies, especially for ardeid-cormorant associations and in regions such as Central America. Here, geospatial data on vegetation associated with a mixed colony, established in a small alluvial forest northwest of El Salvador and collected from June to November 2015 was assessed to identify some behavioural and habitat features that could influence nest-site selection. Four ardeid species (Ardea alba, Egretta thula, Bubulcus ibis, and Nycticorax nycticorax) and one cormorant (Phalacrocorax brasilianus) conformed the colony, where the last was the outstanding species. The total area of the colony was 2.14 ha (14% of La Barra forest) with high nest densities (584.58 nests/ha). Spatial analyses indicate that some species prefer to occupy trees/shrubs close to other trees/shrubs with conspecific or similarly sized species. A remarkable height-strata distribution was found, with large-sized species in the canopy, and small-sized species in the lower strata. The resulting estimates of the generalized linear models applied suggest that the within-colony nest-site selection is determined by the combination of higher heights of the tree/shrub used for nesting, nearest distance to a food source, fewer species sharing the same tree/shrub and an increasing effect of the interaction of the latter two factors. Finally, the temporal evolution of La Barra’s colony shows that the increasing number of Neotropical Cormorants (Phalacrocorax brasilianus) could be shaping and threatening the colony’s species structure and possibly the vegetation as well. Conservation measures should be implemented to manage the population of this species.

Abstract Microturbellarians are all mostly small free-living Platyhelminthes that do not belong to either the Polycladida or Tricladida order. This group includes species of the clades Catenulida and Rhabditophora. Species of microturbellarians are known to live in marine and continental waters such as rivers, where they are diverse and abundant. However, there are few records of microturbellarians in most of the rivers of the Pacific slope of Peru. Here, we report eight species of microturbellarians from the Chillón River, in the central region of Peru. Of the total species recorded, five (Gieysztoria cuspidata, G. bellis, Myostenostomum vanderlandi, Stenostomum tuberculosum and S. saliens) represent the first reports on the Pacific slope of the Neotropical region in Peru, thereby increasing the diversity of microturbellarians in this country.

ABSTRACT We report hymenopteran larval and pupal parasitoids of the Dasiops species in sweet granadilla (Passiflora ligularis J.) orchards in a Peruvian Andean forest. Flower bud and fruit samples infested by Dasiops were collected in three orchards from Oxapampa (Pasco, Peru). In addition, we exposed non-parasitized Dasiops pupae at ground level to verify the presence of pupal parasitoids. We identified Utetes anastrephae (Viereck) and Opius sp. (Hymenoptera: Braconidae) on flower buds infested b.y Dasiops inedulis Steyskal. However, Aganaspis pelleranoi (Brèthes) (Hymenoptera: Figitidae) emerged from D. frieseni pupae reared from unripe fruits. Also, the pupal parasitoids Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) and Coptera sp. (Hymenoptera: Diapriidae) emerged from pupae of both D. inedulis and D. frieseni exposed to parasitism at ground level. Our findings shed new light into new interactions for species in the genus Dasiops and their larval and pupal parasitoids in sweet granadilla agroecosystems from the Neotropical region.

ABSTRACT We describe for the first time the call of Rhinella festae (Peracca, 1904), recording it in captivity inside a plastic bag. The call is composed of 1 to 2 multi-pulsed notes (2–5 pulses), has an average duration of 0.72 s, and a dominant frequency of 1.40 kHz. This species is characterized by the absence of vocal slits and sacs, so the emission of this call would be considered unusual and uncommon. In addition to the purpose of improving the knowledge of species suggested as mutes, we have also compiled information from other anuran species that emit sounds with the absence of these anatomical structures.

ABSTRACT Bon Accord Lagoon (BAL), Tobago is home to a Thalassia testudinum (K.D. Koenig, 1805) dominated seagrass community and polychaetes usually show an affinity to seagrass beds compared to other environments. The objectives of this study were to investigate the polychaete community associated with the Thalassia beds in BAL, determine seasonal variation, and compare with the neighbouring hard bottom polychaete community in Mt. Irvine Bay (MIB). Benthic macroinvertebrates were sampled using a 15 cm diameter corer at a depth of 10 cm. Six stations were sampled during the wet and dry seasons of 2018. Samples were sieved in the field using a 0. 5 mm mesh screen. They were stained and preserved with a 10% formalin-seawater mixture, sorted and macrofaunal species identified to the lowest possible taxonomic level. Thirty – one polychaete families were ranked according to trophic categories as described by Fauchald and Jumars (1979) and updated where possible. Average family density for the dry season was recorded at 206.89 ± 307.53 ind/m2 and 129.55 ± 227.23 ind/m2 for the wet. Maldanidae and Syllidae recorded highest densities for dry and wet seasons respectively. Deposit feeders were the largest trophic group represented across both seasons in the BAL with Maldanidae being the most dominant. Carnivorous polychaetes dominated MIB with Syllidae being the most dominant. BAL showed higher diversity and richness compared to MIB. Based on functional traits of the community the environment at BAL can be regarded as healthy. This study establishes a much-needed baseline for future research and management of marine biodiversity in southwest Tobago.

ABSTRACT The male and female terminalia of the poorly known sharpshooter Macugonalia semiguttata are described and illustrated for the first time based on specimens from a mountainous region in Rio de Janeiro State, southeastern Brazil (Atlantic Forest). External characters of the head, thorax, and abdomen of this species are also described and illustrated. Macugonalia semiguttata is compared with other seven similar species of the diverse genus Macugonalia Young, 1977. Among the 28 known species of this genus, it is apparently closely related to Macugonalia dallasi (Signoret, 1853), Macugonalia geographica (Signoret, 1855), and Macugonalia elegantula Cavichioli, 2004. Specimens of M. semiguttata were collected from the leaves and branches of shrubs and small trees in an area of low forest (circa 1,700 m a.s.l.), which is intermediate between the typical Atlantic Forest and the vegetation of alpine fields.
