“…The department of Nariño is considered an area of high bat species richness (Ramírez-Chaves and Noguera-Urbano 2010), with 23 species of insectivorous bats reported (Calderón-Leytón et al 2020). To date, eld studies in Nariño have focused on the analysis of plant-bat interactions (Cabrera-Pantoja 2007), species inventories (Ramírez-Chaves and Noguera-Urbano 2010), activity patterns, and species abundance (Martínez 2007). Our study aimed to provide the rst description of insectivorous bat echolocation calls for this region.…”

Diversity surveys may be performed by different sampling methods. In the case of bats, the use of traditional methods such as mist nets, harp traps, and roost detection have limitations in widely covering the diversity in a landscape. Most registered species are restricted to species that forage at the undergrowth or in enclosed spaces. However, acoustic monitoring is complementary to conventional methods and can help obtain more complete bat inventories while avoiding alterations in usual foraging activities and disruption in their life cycles. This study describes the acoustic parameters (spectral and temporal variables) of the echolocation pulses of insectivorous bats to characterise acoustically different species of bats present in southwest Colombia. We recorded echolocation calls between December 2017 and May 2020 in the Andean and Pacific regions of the department of Nariño. A total of 81 sequences from free-flying bats were analysed from eight species belonging to three families: Vespertilionidae, Molossidae and Emballonuridae. Myotis riparius and Lasiurus blossevillii were registered for the first time in Nariño Department. The species M. albescens, M. keaysi, M. riparius and L. blossevillii (Vespertilionidae) had pulses of frequency modulated with a quasi-constant ending; Molossus molossus, Tadarida brasiliensis and Promops centralis (Molossidae) had pulses with constant and quasi-constant frequencies; and Saccopteryx bilineata (Emballonuridae) had pulses with quasi-constant frequencies. This study enriches the efforts to solve acoustic species classification issues of insectivorous bats in the Neotropics.

Description and notes on natural history of a new species of Parosus Sharp, 1887 (Coleoptera, Staphylinidae, Oxytelinae) living in floral bracts of Columnea medicinalis L. (Gesneriaceae)

A new species of the recently revised genus Parosus is described, P. amayae López-García Marín-Gómez sp. nov., from adult and larval specimens collected in bracts of Columnea medicinalis in the Natural Reserve Río Ñambí (Southwestern Colombia). Observations on the interaction with the plant, subsocial behavior, and population density are presented and discussed. Adults and larvae apparently live together and feed on eggs and larvae of flies that develop inside the decomposing fruits of C. medicinalis. The new species is illustrated by color habitus photos, as well as its L1 and L3 larvae, male and female genitalia are depicted by line drawings.

Speciation by hybridization has long been recognized among plants and includes both homoploid and allopolyploid speciation. The numbers of presumed hybrid species averages close to 11% and tends to be concentrated in a subset of angiosperm families. Recent advances in molecular methods have verified species of hybrid origin that had been presumed on the basis of morphology and have identified species that were not initially considered hybrids. Identifying species of hybrid origin is often a challenge and typically based on intermediate morphology, or discrepancies between molecular datasets. Discrepancies between data partitions may result from several factors including poor support, incomplete lineage sorting, or hybridization. A phylogenetic analysis of species in Columnea (Gesneriaceae) indicated significant incongruencies between the cpDNA and nrDNA datasets. Tests that examined whether one or both of the datasets had the phylogenetic signal to reject the topology of the alternate dataset (Shimodaira and Hasegawa [SH] and approximately unbiased [AU] tests) indicated significant differences between the topologies. Splitstree analyses also showed that there was support for the placement of the discrepant taxa in both datasets and that the combined data placed the putative hybrid species in an intermediate position between the two datasets. The genealogical sorting index (GSI) implied that coalescence in nrDNA had occurred in all species where more than a single individual had been sampled, but the GSI value was lower for the cpDNA of most of the putative hybrids, implying that these regions have not yet coalesced in these lineages despite being haploid. The JML test that evaluates simulated species pairwise distances against observed distances also implies that observed nrDNA data generate shorter distances than simulated data, implying hybridization. It is most likely that C. gigantifolia, C. rubriacuta, and C. sp. nov. represent a lineage from a hybrid ancestor, but C. moorei may be a more recent hybrid and may still be undergoing hybridization with sympatric species.
