Bat Diversity

The Calima River Basin is part of the Chocó Biogeográfico Ecoregion in the Pacific Coast of Colombia. Here, we compile a bat species checklist recorded for the Basin and describe the bat diversity patterns found in the mid-Calima Basin (the gradient from 300 – 1,400 m a.s.l.). The checklist comprises 55 bat species for the Basin. In the mid-Calima, 31 bat species occur (permanently or seasonally). Our results show complementary diversity patterns of bat assemblages living below and above 1,000 m. We also identified an overlap zone between 800 – 1,200 m a.s.l. where at least three pairs of sister species coexists. The sampled area is located where the Chocó and the Andes biogeographical regions are connected. The Calima River Basin has high bat richness, high variation in species composition along the elevational gradient, and harbours threatened and endemic species, highlighting its importance for conservation.

Central South

Populations in the genus Pyriglena Cabanis, 1847, commonly known as fire-eyes, are patchily distributed in central South America from the Pacific slope of the Andes to the Atlantic Forest of Brazil. Pyriglena populations are currently placed into 12 taxa, only five of which are not isolated from their neighbors by distance, a high mountain range, or a major river. In the Thamnophilidae, taxonomic decisions regarding such allopatric populations have primarily rested on differences in vocalizations, thought not to be learned and to play a key role in the speciation process. When we examined Pyriglena vocalizations in this context, the outcomes revealed substantial diversity in their calls, rather than their songs. They commonly delivered four different types of calls, unusual although not unprecedented in thamnophilids. Diversity in calls rather than songs underscores the need to consider all vocalizations in taxonomic studies. The outcomes support the continued recognition of the White-shouldered Fire-eye Pyriglena leucoptera (Vieillot) and Fringe-backed Fire-eye Pyriglena atra (Swainson) as distinct species, and indicate that, in addition, the currently constituted Pyriglena leuconota should be considered three species: the Western Fire-eye Pyriglena maura (Ménétries); the Tapajos Fire-eye Pyriglena similis Zimmer; and the East Amazonian Fire-eye Pyriglena leuconota (von Spix). We also identify taxonomic uncertainties regarding subspecies that require acquisition of additional data and further analysis.

The Astyanax orthodus species-group includes nine species: Astyanax boliviensis sp. nov., A. bopiensis nom. nov., A. embera sp. nov., A. gandhiae sp. nov., A. moorii comb. nov., A. orthodus, A. superbus, A. villwocki and A. yariguies comb. nov. The group is diagnosed by the presence of a series of pinnate-shaped marks (chevrons) located along the lateral midline, which extends from the humeral region to the caudal peduncle. Astyanax bopiensis nom. nov. is proposed as a substitute name for Astyanacinus multidens, which, along with Astyanax yariguies comb. nov., we reassign to Astyanax.We also propose the synonymy of Astyanacinus with Astyanax. The members of the A. orthodus species-group are distributed in northwestern South America, occurring in the Patia River drainage (A. embera sp. nov.) of the Pacific coast of Colombia, the Atrato River Basin (A. orthodus), the Magdalena River Basin (A. yariguies comb. nov.) of Caribbean Colombia, streams of the southern flank of the Andes of the Orinoco Basin in Venezuela (A. superbus), in the upper Amazon River Basin of Colombia, Ecuador and Peru (A. villwocki, A. gandhiae sp. nov.), from the upper Paraguay River (A. moorii comb. nov.), the Madidi and Mamore Rivers, Bolivia (A. boliviensis sp. nov. and A. bopiensis nom. nov.). All species currently included in Astyanacinus are reassigned to the Astyanax orthodus species-group.

Living Material

The genus Monstera is represented in Colombia by 20 species, 12 of them from the Pacific slope of the Andes. Fieldwork between 2017 and 2019 in this region and a thorough revision of the main Colombian herbaria allowed us to discover two undescribed species belonging to Monstera section Monstera. The two new species are described and illustrated using color photographs of vegetative and reproductive features from living material, and compared to Monstera oreophila, M. epipremnoides and M. dissecta from Central America.

A New Species

A new species of miniature orchid, Platystele riograndense, endemic to the Pacific slope of the western Cordillera, Municipality of Restrepo, Valle del Cauca, Colombia, is described and illustrated. Platystele riograndense is similar to P. filamentosa, but the new species has wider leaves, denser and shorter inflorescences and sigmoid (versus convex) lip. Ecological notes are provided. It is the second new species described of Canyon of Rio Grande new protected area in the last four years.

A New Species

ABSTRACT A new species of catfish is described from the Esmeraldas River Basin, Pacific slope, northern Ecuador. Tentatively included in Microglanis, represents the second species of the genus inhabiting the Trans-Andean region. The new species is distinguished from known congeners by a unique combination of external characteristics: head and body color pattern, uniform, pale brown, yellowish or grayish, without any kind of blotches, bands or dots, only a lunate transverse band, dark or black, at caudal-fin origin; adipose-fin origin and forward without lighter or luminous areas. Compared with M. variegatus, the new species has morphometric differences, such as the distances between dorsal and pelvic fins, and between posterior nostrils. Some osteological characteristics are compared with those observed in species of Pseudopimelodidae inhabiting the Pacific versant of Colombia and Ecuador and with some other species of Microglanis.
