Colombia, Nariño dept., Barbacoas, Correg. Altaquer, Reserva Natural Río Ñambí, La Paila, 1°17’12.0"N 78°04’19.4"W, 1400 m, En brácteas de Columnea medicinalis, 3.ii.2014, leg. O.H. Marín-Gómez (1 male, 3 females, NHMW). Colombia, Nariño, Barbacoas, Correg. Altaquer, Reserva Natural Río Ñambí, En brácteas de Columnea medicinalis, 4.ii.2014, leg. O.H. Marín-Gómez (2 males, 2 females, ICN-MHN, 1 male, FMNH, 1 male, 3 females, MHNG). Larvae. Two L 3 larvae collected with the holotype are deposited in FMNH (also deposited here a possibly non-conspecific species, L1 larva and L3 larva, sampled at the same event). Further larvae (an L1 and L 3 larvae illustrated in Figs. 7-8) have the data " Colombia, Nariño, Barbacoas, Correg. Altaquer, Reserva Natural Río Ñambí, En brácteas de Columnea medicinalis, 4.ii.2014, leg. O.H. Marín-Gómez" and are in various conditions and completeness (in FMNH). The larval specimens are similar to those of Paraploderus (Figs. 78–79 in Makranczy, 2016) except the very distinctive dark "stretch marks" found in the abdominal intersegments (Peter M. Hammond, pers. comm.) that are present in Parosus and this is a common feature with Ochthephilus, Thinodromus and Carpelimus, but lacking in Paraploderus. Diagnosis. Parosus amayae López-García & Marín-Gómez sp. nov. is similar to Parosus rossii Makranzcy, 2014 from Ecuador on its color and general habitus. However, the new species can be differentiated by the completely dark brown to black abdomen, larger body size (4.42–5.50 mm), and spoon shaped apexes of the parameres (Fig. 4). In P. rossii the base of the abdomen is lighter, the body size is shorter (2.73–3.72 mm), and the apexes of the parameres are wider and straight. Description. Habitus as in Fig. 3. Measurements (n=10): HW = 1.02 (0.94–1.11); TW = 1.08 (1.01–1.15); PW = 0.96 (0.89–1.04); SW = 0.87 (0.78–0.93); MW = 1.04 (0.89–1.13); AW = 0.86 (0.70–0.91); HL = 0.87 (0.79– 0.93); EL = 0.17 (0.16–0.21); FL = 0.12 (0.10–0.17); Tl = 0.32 (0.30–0.36); PL = 0.63 (0.57–0.69); SL = 0.91 (0.85–0.94); SC = 0.86 (0.83–0.90); FB = 2.67 (2.53–3.0); BL = 4.95 (4.42–5.50). Body 'bicolored'. Head black (supra-antennal prominences only slightly lighter), pronotum strongly reddish brown, elytra and abdomen black to dark brown. Legs, mouthparts, and antennae light reddish brown to orange. Dorsal surface with medium short and medium dense pale setae, slightly longer and sparse on frons, abdomen with much longer and sparser setae. Head slightly wider than long. Mid-antennal articles moderately elongated (antennomere 6 length:width = 0.096: 0.065 mm). Clypeus trapezoidal, ratio of longitudinal distance of supraantennal prominence tip from eyefront to the same from clypeal front = 0.48–0.50. Infraocular ridge conspicuous, ending in a short keel after the posterior ocular edge. Temple straight strongly curved at the posterior 2/3. Eye strongly bulging. Clypeus and supraantennal ridges very shiny, with a few small, scattered punctures only. Vertex dense and strongly punctate. Clypeus slightly elevated, frontoclypeal groove inconspicuous, only as a borderline before the strongly punctured area. Head with about 32–34 'longitudinal' puncture lines, punctation becoming very dispersed in the triangle of the supraantennal prominences and the mid-vertex. Pronotum wider than long, maximum pronotal width 1.91x base width. Base straight, apex medially curved upwards, sides curved, anterior pronotal angles slightly sharp. Pronotal midline slightly elevated, shiny, and glabrous. Each side of midline broadly depressed. Pronotal disc densely punctate, punctures slightly smaller than those on head. Pronotal margins with four widely separated macrosetae on each side, one on the apical margin and the remaining three on the lateral margins. Elytra slightly dilated posteriorly, with two small, elongate impressions behind scutellum. Elytral punctation not umbilicate, as large as on pronotum, separated by about 2 puncture diameters. Hind margin of tergite VII with a medially serrate fringe. Aedeagus as in Fig. 4–5. Spermatheca as in Fig. 6. Etymology. Parosus amayae López-García & Marín-Gómez sp. nov. was named after professor Marisol Amaya-Márquez (Universidad Nacional de Colombia) who has studied the taxonomy and ecology of the species of Columnea for more than twenty years and has made important contributions for knowing the diversity of Gesneriaceae in Colombia. Distribution. The species is only known from the Natural Reserve Río Ñambí (Nariño, Colombia).

Colombia es el país neotropical con mayor diversidad de Gesneriaceae. Sin embargo hay vacíos en el conocimiento de los patrones de distribución y ecología de esta familia, debido a su complejidad taxonómica. En este trabajo se presenta una lista de Gesneriaceae para el departamento del Quindío con datos de hábitat y distribución altitudinal. Se revisaron las colecciones del Herbario Nacional Colombiano (COL) y Herbario de la Universidad del Quindío (HUQ) y se realizó trabajo de campo entre 2009 y 2014 en 70 localidades del Quindío. Se encontraron 43 especies y 11 géneros, con una mayor representación de Columnea, Besleria y Kohleria; nueve especies fueron nuevos registros para el Quindío, tres fueron endémicas y cinco especies nuevas para la ciencia. La mayor riqueza se encontró en los bosques montanos entre 1800 y 2400 m s.n.m., principalmente en interior bosque y cañadas. Los resultados de este trabajo constituyen una línea base para dirigir la investigación en ecología, conservación y su potencial ornamental de las gesneriáceas presentes en el Quindío. Colombia is the most diverse Neotropical country of Gesneriaceae. Nevertheless, there are gaps in knowledge of the distribution patterns and ecology of this family because of their taxonomic complexity. A list of the Gesneriaceae of the Quindío department with data for habitat and altitudinal distribution is presented in this paper. The herbarium collections of the Herbario Nacional Colombiano (COL) and the Herbario de la Universidad del Quindío (HUQ) were reviewed and fieldwork was carried out between 2009 and 2014 in 70 localities of Quindío. Forty three species and 11 genera were found, with a larger representation of Columnea, Besleria and Kohleria genera; nine species were new records for the Quindío; three were endemic and five species are new to science. The greatest richness was found in the montane forest between 1800 and 2400 masl, mainly in forested areas and streams. The results of this work constitute a baseline to conduct research in ecology, conservation and ornamental potential of Gesneriaceae occurring in Quindío.

Compilamos y analizamos los datos de observaciones realizadas entre los años 2001 y 2013 en tres sectores a lo largo del cauce del río La Vieja, ubicado en el valle geográfico del río Cauca, Colombia. Describimos los datos espacial y temporalmente, enfocándonos en identificar patrones de composición y abundancia de especies. Registramos 28 especies de aves acuáticas en 33 transectos, siendo 22 especies observadas en más del 50 % de los transectos. Las diferencias en el número de especies por transecto no fueron significativas entre los tres sectores del río. Sin embargo, dos análisis de agrupamiento, considerando tanto los datos de presencia/ausencia como de abundancia, indicaron que la composición de especies presenta estructura espacial a lo largo del río. En contraste, aunque las observaciones se realizaron durante más de diez años no se encontró evidencia de cambios temporales en la composición de especies. No obstante, algunas especies mostraron tendencias de aumento o disminución en su frecuencia. Presentamos el nuevo registro de una especie (Chloroceryle aenea) para la región. A pesar de que el paisaje asociado al río La Vieja ha sufrido un gran impacto antropogénico, aún conserva una diversidad significativa de aves acuáticas que pueden servir para aportar valor a los planes de conservación en la zona. We compiled and analyzed data gathered from observations during the period 2001-2013 in three sectors along La Vieja river, located in the Cauca river valley, Colombia. We describe spatial and temporal aspects of such dataset, focusing in indentify patterns of species’ composition and abundance. We recorded 28 waterbird species in 33 transects, being 22 species observed in more than 50 % of these transects. The species richness among transects did not shows significant differences. However, two cluster analyses, considering both presence/absence and abundance data, showed that there is spatial structure in the species composition along the river. In contrast, although observations were conducted during more than ten years there is no evidence of temporal changes in species composition. Still, some species showed increase or decrease trends in their frequency. We present a new record for one species(Chloroceryle aenea) for the region. Despite that the landscape surrounding La Vieja river have faced a high anthropogenic impact, the river still presents a significant diversity of waterbirds, which could add value to the conservation plans in the zone.
