    Actual knowledge and expansion of the distribution of the Tricorythopsis rondoniensis (Ephemeroptera, Leptohyphidae).
    (Universidad del Valle, 2016-12-30) Gomes Dias, Lucimar; Cárdenas López, Tatiana; Laython, Marco; Sociedad Colombiana de Entomología - Socolen; Universidad del Valle
    With this work, the known distribution of Tricorythopsis rondoniensis in Colombia is expanded, with the first record of this species for the Amazonas and Guaviare Colombian departments. Additionally, the known distribution of T. rondoniensis expands in the department of Meta, with a new record for the Municipality of San Juan de Arama, the closest to Andean region for the genus. These findings extend the records of this species in Colombia and corroborate the proposed distribution for the genus Tricorythopsis.

    First record of the genus Lithophorus (Coleoptera: Bothrideridae) to Colombia and L. ornatus to South America.
    (Universidad del Valle, 2016-12-30) Forero Avellaneda, Santiago; Amarillo Suárez, Ángela R.; Sociedad Colombiana de Entomología - Socolen; Universidad del Valle
    The genus Lithophorus (Coleoptera: Bothrideridae) has previously been recorded in several countries in the Americas but not in Colombia. This study reports the finding of this genus with the species Lithophorus ornatus in Colombia for the first time. The species constitutes also a new record for South America.

    Registros de Lutzomyia (Diptera : Psychodidae) en nuevas localidades de Colombia.
    (2013-10-21) Barreto, Mauricio; Burbano, María Elena; Barreto, Pablo
    Introducción: Los insectos del género Lutzomyia son vectores biológicos de bacterias, protozoarios y virus que atacan tanto a los seres humanos como a los animales. Tienen importancia sobre todo por cuanto las hembras, que son hematófagas, transmiten las diversas formas de leishmaniasis. En Colombia diferentes estudios han comunicado la distribución geográfica de estos dípteros. Con el presente trabajo se informan las especies en distintas localidades y se incluyen varios lugares sin registros conocidos antes. Materiales y métodos: Los ejemplares de este estudio se capturaron cuando pretendían picar a los colectores y con trampas donde el cebo era la luz o un animal. Varios especimenes se atraparon en sitios de reposo. A los flebótomos así obtenidos se les trató con diversos sistemas para poder disecarlos y montarlos entre lámina y laminilla a fin de hacer las identificaciones hasta especie. Resultados: A partir del estudio de 716 representantes, 124 machos y 592 hembras del género Lutzomyia, en 46 sitios de 29 municipios, 11 departamentos, fue posible identificar 33 especies. Discusión: Se amplía en forma considerable la distribución geográfica de los miembros del género Lutzomyia en varios sitios de Colombia. Se menciona la importancia de algunas especies antropofílicas en su responsabilidad como transmisores de enfermedades, sobre todo de las distintas leishmaniasis y se destaca la necesidad de estudios sistemáticos y taxonómicos a fin de fijar sus papeles en la diseminación de agentes patógenos que afectan a los seres humanos. Introduction: Phlebotomine sand flies are biological vectors of bacteria, protozoa and viruses attacking both human beings and animals. Sand flies are important since females have haematophagous habits and transmit various types of leishmaniases. In Colombia different studies have given the geographic distribution of these insects. This paper reports the finding of species in several localities and includes some places with no previous records. Material and methods: Specimens were captured while attempting to bite on collectors and with traps (light bait and animal bait). Other specimens were trapped in resting places. Sand flies were processed with different techniques regularly used for dissecting and mounting them for species identification. Results: From the study of 716 specimens, 124 males and 592 females, of the genus Lutzomyia in 46 places from 29 municipalities, in 11 departments (= states, provinces) it was possible to identify 33 species. Discussion: The geographic distribution of the genus Lutzomyia is being greatly extended to new Colombian localities. The importance of some anthropophilic species as vectors of diseases, mainly leishmaniases is discussed. The necessity of systematic and taxonomic studies to know the role of these insects in the transmission of pathologies affecting humans is emphasized.

    Taxonomy and distribution of Tapinoma ants (Formicidae: Dolichoderinae) in Colombia.
    (Universidad del Valle, 2018-12-31) García Avendaño, Emira I.; Guerrero, Roberto J.; Sociedad Colombiana de Entomología - Socolen; Universidad del Valle
    The species of the genus Tapinoma are reviewed for the first time in Colombia. Four species are recognized, T. litorale, T. melanocephalum and T. ramulorum are recorded and described, as well one undescribed species. A taxonomic key based on the workers, images and distribution maps are provided.

    The Pheidole ants (Formicidae: Myrmicinae) in the tropical dry forest of Santa Marta, Colombia.
    (Universidad del Valle, 2020-12-26) Camargo Vanegas, José Juan; Guerrero, Roberto Jose; Sociedad Colombiana de Entomología - Socolen; Universidad del Valle; Montoya Lerma, James
    Ants are a conspicuous biotic component within the tropical dry forest, due to their great diversity both at the species and functional level. Of all the ants, those of the genus Pheidole (Formicidae: Myrmicinae) stand out, which have been categorized as a hyperdiverse group due to the high number of species. The latter has made this group a taxonomic challenge during the development of diversity and ecology studies, therefore, local studies that offer information on the identity of the Pheidole species of a given area becomes an important resource for the decision making. The ants of the genus Pheidole in different formations of tropical dry forest in Santa Marta were studied. Thirteen species are registered, of which Pheidole guajirana extends its distributional range to the department of Magdalena, while P. impressa and P. leptina are registered for the first time in the country. The diagnosis and description of the new species P. urbana is also offered and its morphological features are compared with similar species of the “flavens” informal group. The species richness of the genus in the different sampling sites is evaluated and discussed. Distinctive morphological characteristics are offered for each of the species. Moreover, morphological variability is discussed, and multifocal color images are included for the soldiers (major worker) and workers (= minor worker) of each of the registered species.
