    Notes: Abstract The calanoid copepod Eurytemora velox (Lilljeborg, 1853) was found in the backwater system of the Danube River upstream of Vienna (km 1948) in 1994. Since that time, the species has invaded the side arms of the river between kms 1897 and 1988, as confirmed by findings from 10 different localities. In Hungary, the species has been known since 1992. In the present article, we report 15 new sites in the westernmost part of this country. A brief diagnosis of the morphology of male and female of the Austrian specimens is presented, including detailed illustrations of the structures used in this paper for taxonomic analysis. Females show morphological variability mainly on the structure of the fifth leg pair. Right and left legs frequently have a different spinulation pattern. Males show less morphological variability, particularly in the structure of the basis and the distal section of exopod 2 of the fifth left leg. Morphological variation within E. veloxwas determined by comparing specimens from Austria, Hungary and Rumania. The geographic distribution of the species in the Palearctic region, Austria and Hungary is presented.

    Notes: Abstract Calanoid copepods belonging to four species and one subspecies from lakes and ponds mainly from the Cordillera Oriental (22) and Cordillera Central (1) of the Colombian Andes are recorded. Most of the water bodies studied are located in the ‘páramo’ region, between 2996 and 4085 m altitude. The family Boeckellidae is recorded for the first time from Colombia. Taxonomic characteristics of Boeckella occidentalis Marsh, 1906, Boeckella gracilis (Daday,1902) and the diaptomid Prionodiaptomus colombiensis (Thiébaud, 1914) are discussed. A new diaptomid genus, Colombodiaptomus, with one species and one subspecies are established.

    Description: El objeto del estudio fue adelantar la revisión y actualización de la lista de especies de copépodos del Caribe colombiano. El método utilizado se basó en la recopilación crítica de registros en artículos publicados y no publicados, y en resultados propios obtenidos en el estudio del zooplancton recolectado durante el desarrollo de un proyecto en bioinvasiones de aguas costeras en 2010. Veinte especies registradas únicamente en tesis de pregrado requieren comprobación taxonómica y fueron excluidas del inventario. El modelo base de la lista de especies fué aquel publicado por Medellín-Mora y Navas (2010). Diez especies recolectadas durante el proyecto mencionado constituyen nuevos registros. Trece especies registradas en publicaciones de otros investigadores después de 2010 enriquecieron el inventario. Un total de 214 especies de copépodos (158 Calanoida, 38 Cyclopoida, 15 Harpacticoida, 2 Mormonilloida y 1 Monstrilloida) conforman actualmente la lista de especies. La mayoría de especies son de hábitos planctónicos (201), pocas son bentónicas (10) o epibentónicas (3). Se actualizó la nomenclatura de los taxones. La mayor diversidad corresponde a la ecorregión Colombia Oceánica (127 especies), seguida por Tayrona (94), Magdalena (82) y Morrosquillo (78). El menor número corresponde al Archipiélago de San Andrés y Providencia (49). La baja información existente sobre copépodos bentónicos y parásitos sugiere incrementar el estudio de esos grupos, la mayoría de ellos pertenecientes a los órdenes Harpacticoida y Siphonostomatoida.
