Pronura bidoup n. sp. (Collembola, Neanuridae, Neanurinae, Paleonurini) from southern Vietnam

A new species of Pronura Delamare Debouteville, 1953, Pronura bidoup n. sp. is described from the Bi Doup massif in southern Vietnam, where it is largely distributed above 1,350 m. The new species exhibits a combination of characters unusual for the genus: shift of chaeta f towards chaeta e on labium, large central reticulate plate on head, presence of microchaetae on furcal rest, reduced chaetotaxy of legs and abdominal segment VI. It is related to Pronura ornata Deharveng & Bedos, 1993 from high altitude in Thailand

Esta nueva especie presenta una serie de caracteres poco usuales para el género: desplazamiento de la queta f hacia la queta e en el labium, placa central grande reticulada en la cabeza, presencia de microquetas en la base de la furca, quetotaxia reducida en las patas y en el segmento abdominal VI. P. bidoup sp. n. está relacionada con P. ornata Deharveng y Bedos, 1993, que se encuentra a gran altitud en Tailandia

Environmentally vulnerable noble chafers exhibit unusual pheromone-mediated behaviour

Conserving populations of environmentally vulnerable insect species requires a greater understanding of the factors that determine their abundance and distribution, which requires detailed knowledge of their population and community ecology. Chemical ecological tools such as pheromones can be used for non-destructive monitoring of scarab beetle populations, enabling European countries to detect and, in some cases, map the range of some of these species, proving a valuable technique for monitoring elusive saproxylic beetles. In this paper, we investigated the behavioural and chemical ecology of the noble chafer, Gnorimus nobilis L., a model insect species of conservation concern across a Europe-wide distribution, and a red-listed UK Biodiversity Action Plan priority species. We identified a potential pheromone of adult beetles using electrophysiological recordings, behavioural measurements and field trials in the UK. Gnorimus nobilis is highly unusual in that although both sexes produce, at high metabolic cost, the natural product 2-propyl (E)-3-hexenoate, it only attracts males. This pattern of chemical signalling makes the classification of the compound, based on current semiochemical terminology, somewhat problematic, but in our view, it should be termed an aggregation pheromone as a consequence of the production pattern. Since both sexes emit it, but apparently only males respond positively to it, 2-propyl (E)-3-hexenoate may reflect an intermediate evolutionary stage towards developing into a sex-specific signal. From an applied perspective, our study provides a model for the non-invasive surveillance of cryptic vulnerable insect species, without the need for habitat searching or disturbance, and continuous human monitoring
