          Abstract

          RESUMEN El presente trabajo resume las principales tendencias en el conocimiento de los gerromorfos en el ámbito mundial, relacionadas con los avances en sistemática molecular, su uso como indicadores de ambientes cambiantes y la ampliación del saber en varios países Neotropicales. Se revisa la información publicada sobre los Gerromorpha en la última década (2009-2019) en Colombia y se contemplan los diferentes aspectos biológicos, taxonómicos, ecológicos y de distribución geográfica. El desarrollo y el progreso sobre los heterópteros semiacuáticos son la base del emprendimiento de otras investigaciones en Colombia y en el Neotrópico, especialmente en regiones como Mesoamérica y Sudamérica.

          ABSTRACT The present work summarizes the main worldwide trends in the Gerromorphans knowledge which are related to the advances in molecular systematics, their use as indicators of changing environments, and knowledge broadening in several Neotropical countries. The information published about Gerromorphans in last decade (2009-2019) in Colombia is reviewed, and the different biological, taxonomic, ecological and geographical distribution aspects are considered. The development and progress about semiaquatic Heteroptera are the base to undertake further investigations in Colombia and at the Neotropic, especially in regions such as Mesoamerica and South America.

          Los macroinvertebrados como bioindicadores de la calidad del agua: cuatro décadas de desarrollo en Colombia y Latinoamerica

          La comunidad de macroinvertebrados acuáticos mejor estudiada en Colombia es la entomofauna. Los órdenes Ephemeroptera, Plecoptera y Trichoptera son los mejor conocidos en cuanto a su taxonomía, ecología y su utilización como bioindicadores de la calidad del agua. Es necesario profundizar en el estudio de algunos grupos como los anélidos, moluscos, ácaros y dípteros, de los cuales aún falta conocimiento de su taxonomía y autoecología. El índice BMWP (Biological Monitoring Working Party), desarrollado en Europa en el siglo XX a partir de la década de los años setenta, es muy popular en Colombia y Latinoamérica, pero es necesario hacer adaptaciones para las diferentes regiones en el continente.Este trabajo presenta una revisión de los estudios realizados durante las últimas cuatro décadas en Colombia, y de manera general en Latinoamérica. Se presenta el estado actual del conocimiento de los diferentes grupos de los macroinvertebrados acuáticos en términos de la resolución taxonómica, los aspectos ecológicos y su utilización como bioindicadores de la calidad del agua.

              From water striders to water bugs: the molecular diversity of aquatic Heteroptera (Gerromorpha, Nepomorpha) of Germany based on DNA barcodes

              With about 5,000 species worldwide, the Heteroptera or true bugs are the most diverse taxon among the hemimetabolous insects in aquatic and semi-aquatic ecosystems. Species may be found in almost every freshwater environment and have very specific habitat requirements, making them excellent bioindicator organisms for water quality. However, a correct determination by morphology is challenging in many species groups due to high morphological variability and polymorphisms within, but low variability between species. Furthermore, it is very difficult or even impossible to identify the immature life stages or females of some species, e.g., of the corixid genus Sigara. In this study we tested the effectiveness of a DNA barcode library to discriminate species of the Gerromorpha and Nepomorpha of Germany. We analyzed about 700 specimens of 67 species, with 63 species sampled in Germany, covering more than 90% of all recorded species. Our library included various morphological similar taxa, e.g., species within the genera Sigara and Notonecta as well as water striders of the genus Gerris. Fifty-five species (82%) were unambiguously assigned to a single Barcode Index Number (BIN) by their barcode sequences, whereas BIN sharing was observed for 10 species. Furthermore, we found monophyletic lineages for 52 analyzed species. Our data revealed interspecific K2P distances with below 2.2% for 18 species. Intraspecific distances above 2.2% were shown for 11 species. We found evidence for hybridization between various corixid species (Sigara, Callicorixa), but our molecular data also revealed exceptionally high intraspecific distances as a consequence of distinct mitochondrial lineages for Cymatia coleoptrata and the pygmy backswimmer Plea minutissima. Our study clearly demonstrates the usefulness of DNA barcodes for the identification of the aquatic Heteroptera of Germany and adjacent regions. In this context, our data set represents an essential baseline for a reference library for bioassessment studies of freshwater habitats using modern high-throughput technologies in the near future. The existing data also opens new questions regarding the causes of observed low inter- and high intraspecific genetic variation and furthermore highlight the necessity of taxonomic revisions for various taxa, combining both molecular and morphological data.
