Se presenta la distribución actual de la familia Coryphoridae con dos nuevos registros del género Coryphorus para el departamento del Putumayo, Colombia. Adicionalmente, se muestran detalles de las espinas y setas de las ninfas mediante microscopía electrónica (SEM), y se describen variaciones morfológicas de la genitalia del adulto.
A new species of Tricorythodes is described and illustrated based on nymphs from Colombia. Legs, mouthparts and other parts of the body were photographed through SEM and molecular characterization was performed by amplification of the COImt gene. Tricorythodes carare sp. nov. shows close affinities with T. serratus (Baumgardner & Ávila), both sharing a similar coloration pattern and the presence of chalazae on femora. The new species can be distinguished from T. serratus and all the species of the genus by the following combination of characters: maxillary palp 3-segmented, with apical setae; dorsal surface of median and hind femora with a longitudinal row of 5 to 9 chalazae serrated in the apex, tarsal claws with 4 or 5 marginal denticles and with 1–3 submarginal denticles; posterior margin of the abdominal terga with serrated chalazae in the apex. SEM images and distance analysis of the partial sequences of the COI gene were useful to discriminate the new species from T. serratus (genetic divergence 17–19%). An additional undescribed species of this group is reported from Esmeraldas in Ecuador and for the departments of Sucre and Chocó in Colombia, but it is not described here because of the low number of individuals and the lack of DNA integrity. What is known under the name Tricorythodes serratus is suspected to be a species complex.
El género Cabecar fue reportado para diferentes localidades de Centroamérica y una de Suramérica. En este trabajo se presenta la ampliación de la distribución del género Cabecar para Colombia, con el primer registro en el Parque Nacional Natural Tayrona, en el Caribe colombiano.
Con este trabajo se amplía la distribución de Tricorythopsis rondonienses en Colombia, con el primer registro de la especie para los departamentos de Amazonas y Guaviare. Además, se amplía la distribución de T. rondoniensis en el departamento del Meta, con un nuevo registro para el Municipio de San Juan de Arama, el cual consiste en el reporte más cercano del género hacia la región andina. Estos hallazgos actualizan los registros de la especie en Colombia y corroboran la distribución propuesta para el género Tricorythopsis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
