The Trichoptera of Panama XIII. Further new country records for caddisflies (Insecta: Trichoptera) from the Republic of Panama

The Republic of Panama currently includes 414 recorded species of Trichoptera. Herein we add two new genera (Hydroptilidae: Angrisanoia Ozdikmen, 2008 and Mayatrichia Mosely, 1937) and 17 new country records (Philopotamidae: Chimarra (C.) tapanti Blahnik, Wormaldia bolivari Muñoz-Quesada and Holzenthal, and Wormaldia zunigae Muñoz-Quesada and Holzenthal; Hydropsychidae: Centromacronema pygmaeum Botosaneanu; Hydroptilidae: Brysopteryx esparta Harris and Holzenthal, Byrsopteryx solisi Harris and Holzenthal, Costatrichia falsa Santos, Takiya, and Nessimian, Mayatrichia illobia Harris and Holzenthal, Metrichia amplitudinis Bueno-Soria and Holzenthal, Ochrotrichia boquillas Moulton and Harris, O. conformalis Bueno-Soria and Holzenthal, O. quinealensis Bueno-Soria and Holzenthal, and O. unica Bueno-Soria and Santiago; Leptoceridae: Triaenodes morai Holzenthal and Andersen; Odontoceridae: Marilia kingsolveri Bueno-Soria and Rojas-Ascencio; and, Helicopsychidae: Helicopsyche alajuela Johanson and Holzenthal and Helicopsyche breviterga Flint) to Panama’s caddisfly fauna. The newly recorded taxa increase Panama’s total known caddisfly fauna to 431 species, distributed among 15 families and 55 genera. These results are part of an ongoing effort to characterize the caddisfly fauna of Panama, and to evaluate the aquatic insect diversity of the country’s major watersheds (cuencas).

Agriculture impairs stream ecosystem functioning in a tropical catchment

The expansion of agriculture is particularly worrying in tropical regions of the world, where native forests are being replaced by crops at alarming rates, with severe consequences for biodiversity and ecosystems. However, there is little information about the potential effects of agriculture on the functioning of tropical streams, which is essential if we are to assess the condition and ecological integrity of these ecosystems. We conducted a litter decomposition experiment in streams within a tropical catchment, which were subjected to different degrees of agricultural influence: low (protected area, PA), medium (buffer area, BA) and high (agricultural area, AA). We quantified decomposition rates of litter enclosed within coarse-mesh and fine-mesh bags, which allowed the distinction of microbial and detritivore-mediated decomposition pathways. We used litter of three riparian species representing a gradient in litter quality (Alnus acuminate > Ficus irtsipida > Querns burnelioides), and examined detritivore assemblages through the contents of litterbags and benthic samples. We found that the increasing agricultural influence promoted microbial decomposition, probably due to nutrient-mediated stimulation; and inhibited detritivore-mediated and total decomposition because of reduced detritivore numbers, most likely caused by pesticides and sedimentation. Effects were evident for Alnus and Ficus, but not for Querns, which was barely decomposed across the gradient. Our study provides key evidence about the impact of agriculture on topical stream ecosystem functioning, which is associated to changes in stream assemblages and may have far-reaching repercussions for global biochemical cycles.

Distribución y diversidad de la comunidad de macroinvertebrados acuáticos en la sub cuenca alta , media y baja del río Caldera, Chiriquí, Panamá.

With the objective of determine the diversity and quality of water, were sampled aquatic macroinvertebrates in six stations along the subbasins high, middle and lower of Caldera river, Chiriqui, Panama, during the dry season (December 2011 April 2012). In each station was sampled twice per month in periods of 45 minutes each. In this study were used three types of sampling: a-) triangular net, b-) sampling rocks with entomological weezers and c-) litterfall collection. Samples were placed in plastic containers properly labeled, with 70 % ethanol. The total diversity for the study area was high (H '= 3.37), which was composed by 5849 individuals, identified in 115 genera belonging to 62 families, in 16 orders of the classes Oligochaeta, Insecta, Aracnoidea and Gastropoda. The greater abundance of individuals was obtained at station 2, with a value of 1278, and the orders that showed higher abundance were Diptera and Trichoptera, 1489 and 1298 individuals, respectively. The most representative families were Simuliidae and Chironomidae, while the order with the most quantity of families was Coleoptera. The Sorenson quantitative index showed that the stations with greater similarity were: 5 and 6 with a value of 69.3 %, whereas the lowest similarities were between the stations 2 and 6, with 11.3 %. According to BMWP/Pan, the water quality of Caldera river, during this season was good to excellent. This study showed the applicability of using aquatic macroinvertebrates to determine damage to fluvial ecosystems.Con el objetivo de determinar la diversidad y calidad del agua se realizaron muestreos de macroinvertebrados acuáticos en seis estaciones a lo largo de las subcuencas alta, media y baja del rio Caldera, Chiriquí, Panamá, durante la época seca (diciembre de 2011 - abril de 2012). Cada estación fue muestreada dos veces por mes durante perfodos de 45 minutos cada una.Se utilizaron tres tipos de muestreos los cuales fueron: a-) la red triangular, b-) muestreo en rocas con pinzas entomológicas, y c-) recolecta de hojarasca. Las muestras fueron colocadas en envases plásticos debidamente rotulados, y con alcohol al 70 %. La diversidad total para el área de estudio fue alta (H'= 3.36), la cual estuvo compuesta por 5849 individuos, identificadas en 115 géneros pertenecientes a 62 familias, en 16 órdenes de las clases Oligochaeta, Insecta, Aracnoidea y Gastropoda. La mayor abundancia de individuos se obtuvo en la estación 2 con un valor de 1278 individuos, y los órdenes que presentaron mayor abundancia fueron Díptera y Trichoptera, con 1489 y 1298 individuos, respectivamente. Las familias más representativas fueron Simuliidae y Chironomidae, mientras que el orden con mayor cantidad de familias fue Coleoptera. El indice de Sorenson cuantitativo mostró que las estaciones con mayor similitud fueron la 5 y la 6 con un valor de 69.3 %, en tanto que las de menor similitud fueron la 2 y 6 con 11.3 %. Según el BMWP/Pan, la calidad del agua del río Caldera durante esta época fue de buena a excelente. Este estudio mostró la aplicabilidad del uso de macroinvertebrados acuáticos, para determinar daños en los ecosistemas fluviales

The Trichoptera of Panama. XXVI. Status of the genus Protoptila (Trichoptera, Glossosomatidae)

The caddisfly genus Protoptila (Trichoptera, Glossosomatidae) in Panama is currently represented by 15 species, including four endemic species and 11 species also found in Costa Rica. The shared occurrences of Panamanian species with other countries in the region are minimal. Herein, we describe and illustrate a new species, Protoptila harrisi sp. nov., and add one new country record, Protoptila bribri Holzenthal & Blahnik, 2006. These additions are the result of several projects conducted by the Aquatic Invertebrate Research Group at the Universidad Autónoma de Chiriquí. The Republic of Panama now has 17 species of Protoptila and 535 species of caddisflies distributed among 15 families and 56 genera
