RESUMO
Quichuana Knab, 1913 is a Neotropical genus of flower flies (Diptera: Syrphidae) with 50 valid species. Adults of this genus are flower visitors and their larvae are usually associated with the phytotelmata of bromeliads and heliconias, actively participating in the recycling of nutrients in forest environments. Despite their importance in ecosystem dynamics, Quichuana larvae are poorly known. Herein we describe the immature stages of Quichuana pogonosa Fluke, 1937 from samples collected from the phytotelmata of two terrestrial bromeliad species in the state of Paraná, Brazil. We provide illustrations of the egg, third instar larva and puparium, as well as information on the life cycle of the species. Additionally, we describe and illustrate the male genitalia and present the DNA-barcoding based on larva and adult specimens.(AU)

RESUMO
Chaetonerius Hendel is the only native genus of Neriidae from the African continent, with 21 species described. Although widely distributed across the Afrotropical region, the species of Chaetonerius are still poorly known and recent efforts are being devoted to clarify the taxonomy of the family and discover its diversity. Here, we describe a new neriid species from Tanzania, Chaetonerius stichodactylus sp. n. Illustrations of the male holotype, including the external and internal genitalia, are presented and a key for the species of Neriidae of Tanzania is provided.

Introducción: desde 1996, Colombia inició una serie de cambios institucionales orientados a mejorar las condiciones alimentarias y nutricionales en el país, tal como el Plan Nacional de Alimentación y Nutrición (PNAN 1996-2005); y en el 2007 a través del Consejo Nacional de Política Económica y Social, se declaró la política de Seguridad Alimentaria y Nutricional para el país.Métodos: se realizó un muestreo no aleatorio en el que participaron 113 hogares con niños; y se utilizó como instrumento para la recolección de datos la Escala Latinoamericana y del Caribe de Seguridad Alimentaria ELCSAResultados: se halló un nivel de inseguridad alimentaria en hogares con adultos y algunos con niños, del 70,8% (adultos) y 67.3% (niños) respectivamente.Conclusión: la alta inseguridad alimentaria fue independiente de las escuelas, las comunidades y los municipios de la región.

Objetivo: explorar cómo el adulto afronta o afrontaría el sentimiento de soledad. Metodología: estudio descriptivo transversal. Se realizó una pregunta abierta a 180 adultos para identificar la posible forma de enfrentar la soledad si ésta se presenta o se presentara en algún momento de la vida. Resultados: se obtuvieron cinco categorías sobre cómo afronta o afrontaría la soledad: buscar compañía (36%), distracción (21.9%), aceptación (14.6%), Dios (10.1 %) y otros (17.4). Conclusiones: el afrontamiento de la soledad asumido por los adultos está enfocado a formas activas, se advierte la necesidad de relacionar recursos externos e internos con la vida diaria para promover potencialidades en el individuo y, por ende, mayores posibilidades para afrontar su sentimiento de soledad.
Objective: to explore how the adult faces and / or would face the feeling of loneliness. Methods: cross sectional study. An open question was performed to 180 adults to identify possible ways to address loneliness, if it's the occurring or if it occurs at some point in life. Results: five categories were obtained about the way they faced or would face loneliness: search company (36%), distraction (21.9%), acceptance (14.6%), God (10.1%) and other (17.4%). Conclusions: facing loneliness by adults is more focused on active forms, visualizing the need to connect external and internal resources in daily life to promote the individual potential, and therefore they are more likely to face their feelings of loneliness.
