Heliographic signalling in Haploglenius Burmeister, 1839 (Neuroptera Ascalaphidae)

The males of the ascalaphid genus Haploglenius are equipped with a movable pronotal flap, covering a white thoracic membrane, whose function remains poorly known. Few recent original observations, conducted on undisturbed specimens in their natural environment, suggest that this structure is part of a complex visual communication system based on intermittently showing the bright, reflecting, thoracic white area on a dark background. This behaviour is probably associated with courtshi

First record of gynandromorphism in the subfamily Dryininae (Hymenoptera: Dryinidae)

View on Scopus A gynander specimen belonging to the genus Dryinus Latreille, 1804 (Hymenoptera: Dryinidae) is described from Ecuador (Zamora Province). It has a female aspect, but with male genitalia, no chelae and no Antennal Dorsal Organs (ADOs). This is the first record of a gynander specimen of Dryininae

Invasive ants of continental Ecuador, a first account

 Management of invasive species is considered one of the great challenges deriving from Global Change that our societies currently face, besides deforestation and the warming of the atmosphere. Little is known about the invasive ants in continental Ecuador, despite the world-wide demonstrated aggressiveness, negative ecological impact, and economic losses caused by them. Most Ecuadorian records are from the Galápagos Islands and there is yet no inventory for the mainland. Gleaning records from the literature and local entomological collections, we present the first list of invasive ants present on mainland Ecuador. A total of 16 invasive ant species are recorded. Ten ant species are foreign to the country. The remaining six ant species are native to Ecuador and invasive elsewhere. Records of Cardiocondyla minutior, Monomorium floricola, Monomorium pharaonis, Tapinoma melanocephalum, and Tetramorium bicarinatum are the first ones for continental Ecuador. Furthermore, Cardiocondyla wroughtonii and Tetramorium lucayanum are reported for the first time for the country. El manejo de las especies invasoras es considerado uno de los grandes desafíos que impone el Cambio Global a nuestras sociedades, junto con la deforestación y el calentamiento de la atmósfera. Se conoce muy poco sobre las hormigas invasoras en el Ecuador continental, incluso cuando se ha demostrado en el resto del mundo su agresividad, los impactos negativos en los ecosistemas y las pérdidas económicas que causan. La mayoría de registros de hormigas invasoras en el Ecuador provienen de las Islas Galápagos y no existe un inventario de ellas para el Ecuador continental. Aquí compilamos registros de hormigas invasoras presentes en la literatura y en colecciones entomológicas locales para crear la primera lista de hormigas invasoras presentes en el Ecuador continental. Se registra la presencia de un total de 16 especies de hormigas invasoras. De estas, diez especies son extranjeras, pero invasoras en el Ecuador; y seis especies son nativas en el Ecuador e invasoras en el exterior. Proveemos los primeros registros para Ecuador continental de Cardiocondyla minutior, Monomorium floricola, Monomorium pharaonis, Tapinoma melanocephalum, y Tetramorium bicarinatum. Además, los registros de Cardiocondyla wroughtonii y Tetramorium lucayanum son los primeros para el país
