RESUMEN Reduviidae incluye el mayor número de especies de depredadores terrestres del Orden Hemiptera, incluyendo depredadores de potenciales plagas en los agroecosistemas. A pesar de la gran cantidad de estudios sobre la taxonomía y morfología del grupo, su filogenia y estrategias reproductivas aún no han sido totalmente dilucidadas. En este trabajo, la histología del tracto reproductivo masculino de Zelus longipes fue descrita con el objetivo de incrementar las fuentes de caracteres para estudios de biología reproductiva del grupo. Para esto fueron utilizadas técnicas de microscopia de luz. Los machos adultos fueron recolectados directamente en un cultivo de maíz, en el municipio de Rio Paranaíba, Minas Gerais. El sistema reproductor está compuesto por dos testículos, cada uno con siete folículos con quistes en diferentes fases del espermatogénesis, vasos deferentes, vesículas seminales, glándulas accesorias pareadas y lobadas en un ducto eyaculatorio. Cuando los espermatozoides están maduros salen de los testículos agrupados en haces y quedan almacenados en las vesículas seminales. Las glándulas accesorias producen diferentes tipos de secreciones que se unen al esperma para formar el semen. Los conductos deferentes fluyen hacia un solo conducto eyaculador.

ABSTRACT Reduviidae comprises the largest number of land predator species of the Order Hemiptera, including predators of potential pests in agroecosystem areas. Despite the large number of taxonomic and morphological studies of the group, its phylogeny and reproductive strategies have not been elucidated. This work presents the male reproductive system morphology and histology of the assassin bug Zelus longipes aiming to increase the character sources for reproductive biology studies of the group. For this, light microscopy techniques were used. The adult males were collected in a corn crop area in Rio Paranaíba, municipality of Minas Gerais, Brazil. The male reproductive system of Z. longipes comprises of a pair of testes, with seven follicles each and cysts at different stages of spermatogenesis, vasa deferentia, two seminal vesicles, pairs of paired and lobed accessory glands, and an ejaculatory duct. When the sperm are mature they leave the testes grouped into bundles and are stored in the seminal vesicles. The accessory glands produce different types of secretions that join the spermatozoa to form the semen. The deferent ducts flow into a single ejaculatory duct.

ABSTRACT A new species of Thraulodes Ulmer 1920 is described based on nymphs and imagos from Tapias river, Caldas department, Colombia. The mature nymphs were reared until the emergence of the imagos. Thraulodes latinus sp. n. can be distinguished from other species of the genus by: In males, the forewing without cross veins basal to bullae and with 11-14 cross veins distal to bullae, abdominal and legs color pattern, styliger plate redounded, with a long and digitiform median projection and shape of penes with apicolateral area forming an “ear-like” projection. In nymphs, the claws with eight denticles and the general coloration pattern. Additionally, data on the anatomy of the reproductive tract of both the male and female imago of the new species are presented.

Abstract In the Neotropical region, especially South America, Leptophlebiidae achieves its higher diversity, with 45 genera and almost 250 species. In Colombia, the diversity about this family is underestimated, with only 22 species reported so far. In order to contribute to the current knowledge of the Leptophlebiidae in Colombia we examined the adults of this family deposited at the Colección Entomológica del Programa de Biología, Universidad de Caldas. In addition to the historical records herein presented, nine species are registered for the first time from the country (Farrodes savagei, F. tepui, F. xingu, Hagenulopsis minuta, Terpides contamanensis, T. echinovaris, T. ornatodermis, Tikuna atramentum, and Ulmeritoides flavopedes). Besides that, additional records are presented for 12 species of the following genera: Askola, Farrodes, Simothraulopsis, Tikuna, Ulmeritoides, Hydrosmilodon, Terpides, Choroterpes, Paramaka, and Hagenulopsis. With these additional and new records, we update the list of Leptophlebiidae from Colombia to 33 species and 14 genera.

Resumo: Pentatomidae compreende um diverso grupo de percevejos amplamente distribuídos na região Neotropical. Muitas espécies são fitófagas e causam algum tipo de injúria em plantas, podendo se configurar como pragas agrícolas. Neste trabalho, descrevemos a anatomia do trato reprodutor de machos e fêmeas em três importantes pragas agrícolas da Colômbia: Piezodorus guildinii (Westwood 1837) e Chinavia ubica (Rolston 1983) na cultura de soja e Oebalus insularis (Stål 1872) na cultura do arroz. Para isto, foram utilizadas técnicas de microscopia de luz. A anatomia do trato reprodutor em machos sexualmente maduros nas três espécies consistiu de um par testículos, vasos deferentes, vesículas seminais, bulbo ejaculatório, um ducto ejaculatório que se abre em um aedeagus e glândulas acessórias pareadas. O trato reprodutor das fêmeas consistiu de um par de ovários, cada um com sete ovaríolos telotróficos-meroísticos, um par de ovidutos laterais, uma espermateca e a câmara genital. Os ovaríolos telotróficos possuíam quatro diferentes regiões: filamento terminal, germário, vitelário e pedicelo. As diferenças entre as espécies foram observadas no tamanho, cor e posição das estruturas ao logo do trato reprodutivo. A biologia reprodutiva de insetos gera caracteres que fornecem informações para trabalhos envolvendo evolução, comportamento e estratégias de controle de pragas.

Abstract: Pentatomidae comprises a diverse group of stink bugs widely distributed in the Neotropical region. Many species are phytophagous and cause injuries to plants, and can thus be defined as agricultural pests. In this study, the anatomy of the female and male reproductive tracts of three important agricultural pests in Colombia is described: Piezodorus guildinii Westwood, 1837 and Chinavia ubicaRolston 1983, found on soybeans, and Oebalus insularis Stål, 1872, found in rice crops. For that, light microscopy techniques were used. The anatomy of the reproductive tract of sexually mature males of the three species studied consisted of a pair of testes, vas deferens, seminal vesicles, ejaculatory bulb, an ejaculatory duct that opens into an aedeagus, and paired accessory glands. The reproductive tract of females consisted of a pair of ovaries, each with seven telotrophic-meroistic ovarioles, a pair of lateral oviducts, common oviduct, spermatheca, and a genital chamber. Telotrophic ovarioles were comprised of terminal filament, tropharium, vitellarium, and pedicel. Differences in size, color, and position of structures along the reproductive tract were observed between the species examined. Reproductive biology of insects provides informative characters for behavioral and evolutionary studies, as well as useful data for pest control strategies.

Abstract In Colombia, the taxonomical understanding of ectoparasites (Diptera: Streblidae and Nycteribiidae) of bats is scarce, despite the high diversity of hosts. This fact reflects the lack of important information on the group and poses the need for studies that expand the knowledge on bat ectoparasites in different regions of the country. The aim of this study was to contribute pioneer knowledge on bat ectoparasitic insects in the department of Caldas, located in the Central Andes Mountain range of Colombia. We assessed 318 bats from four eco parks in the city of Manizales, and collected 234 ectoparasitic insects. We provide the first report of the family Streblidae for Caldas, with seven genera and eight species: Anastrebla caudiferaeWenzel, 1976, Anatrichobius scorzaiWenzel, 1966, Exastinion oculatumWenzel, 1976, Megistopoda proxima (Séguy‚ 1926), Paratrichobius longicrus Ribeiro, 1907, Paraeuctenodes similisWenzel, 1976, Trichobius longipes Rudow, 1871, and Trichobius tiptoniWenzel, 1976. In addition, we report the species Basilia ferrisi Schuurmans Stekhoven, 1931 and Basilia sp. for the family Nycteribiidae.

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 orroboran la distribución propuesta para el género Tricorythopsis.

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.

Trichoptera es uno de los órdenes de insectos acuáticos más importantes debido a su diversidad y amplia distribución de sus especies. Está presente en casi todas las regiones biogeográficas desempeñando un papel fundamental en las cadenas tróficas de los ecosistemas. La familia Atriplectididae NEBOISS, 1978 tiene una distribución dispersa a lo largo del mundo y está representada solo por tres géneros en Australia, Madagascar y el Neotrópico. Las larvas de Atriplectididae presentan una morfología atípica dentro de los Trichoptera, presentando una cabeza y mesonoto estrechos, alargados y retráctiles. Por lo general, se encuentran en sedimentos arenosos en el fondo de pequeños arroyos y lagos. En el Neotrópico tienen una distribución muy restringida al norte de los Andes (Perú, Ecuador, Bolivia y Colombia) y sureste de Brasil. Para Colombia se ha registrado en zonas altoandinas, únicamente para Cundinamarca, Quindío y Antioquia. En un muestreo reciente realizado en el municipio de Manizales, con el objetivo de ampliar el conocimiento de los macroinvertebrados acuáticos en los Andes centrales de Colombia, se realizó un nuevo registro de Neoatriplectides HOLZENTHAL, 1997 (Atriplectididae) para el departamento de Caldas. Este registro amplía el rango de distribución de la familia en Suramérica y aporta información inédita de la distribución geográfica del género en Colombia.

Trichoptera is one of the most important orders of aquatic insects due to their diversity and the wide distribution of their species. It is present in almost all biogeographic regions performing a key role in ecosystem food chains. The family Atriplectididae NEBOISS, 1978 has a scattered distribution throughout the world and is represented only by three genera in Australia, Madagascar and the Neotropics. Atriplectididae larvae present an unusual morphology within Trichoptera, showing a narrow, elongated and retractable head and mesonotum. Usually, they are found in sandy sediments in the bottom of streams and small lakes. The distribution in the Neotropics is restricted to the Northern Andes (Peru, Ecuador, Bolivia and Colombia) and South-Eastern Brazil. In Colombia it has been recorded in the Andean highlands, only for the Departments of Cundinamarca, Quindío and Antioquia. In a recent sampling performed in the municipality of Manizales, with the aim of increasing knowledge of aquatic macroinvertebrates in the central Andes of Colombia, a new record of Neoatriplectides HOLZENTHAL, 1997 was made for the department of Caldas. This record extends the distribution range of the family in South America and provides unpublished information on the geographic distribution of the genus in Colombia.
