Se presenta información específica de los ejemplares del infraorden Gryllidea depositados en la Colección Entomológica LOU-Arthr del Centro de Investigación Forestal de Lourizán y se revisa su estado de conocimiento en Galicia. Actualmente la colección cuenta con 450 ejemplares pertenecientes a cuatro de las cinco familias conocidas de la península ibérica (Gryllidae, Trigonidiidae, Mogoplistidae y Gryllotalpidae), seis subfamilias (Gryllinae, Oecanthinae, Trigonidiinae, Nemobiinae, Mogoplistinae y Gryllotalpinae), y 10 táxones [Eugryllodes escalerai (Bolívar, 1894), Gryllus (Gryllus) campestris Linnaeus, 1758, Gryllus (Gryllus) bimaculatus De Geer, 1773, Eumodicogryllus bordigalensis (Latreille, 1804), Oecanthus pellucens pellucens (Scopoli, 1763), Trigonidium (Trigonidium) cicindeloides Rambur, 1838, Nemobius sylvestris sylvestris (Bosc, 1792), Pteronemobius (Stilbonemobius) lineolatus (Brullé, 1835), Pseudomogoplistes vicentae Gorochov, 1996 y Gryllotalpa vineae Bennet-Clark, 1970].

SUMMARY We investigated five different descending brain interneurons with dendritic arborizations in the deutocerebrum in the crickets Gryllus bimaculatus and G. campestris. These interneurones convey specific antennal mechanosensory information to the ventral nerve cord and all responded to forced antennal movements. These interneurones coded for velocity and showed preferences for distinct sectors of the total range of antennal movements. Their axons descended into the posterior connective either ipsilateral or contalateral to the cell body. Electrical stimulation of sensory nerves indicated that the interneurons received input from different afferents of the two antennal base segments. One interneuron had a particularly large axon with a conduction velocity of 4.4ms−1. This was the only one of the five interneurons that also received visual input. Its activity was reduced during voluntary antennal movements. The reduction in activity occurred even after de-efferentation of the antenna, indicating that it had a central origin. Although we do not have experimental evidence for behavioural roles for the descending antennal mechanosensory interneurons, the properties described here suggest an involvement in the perception of objects in the path of the cricket.
