Diptera: Athericidae) Boletín de la Sociedad Entomológica Aragonesa (S.E.A.), nº 54 (30/6/2014): 349–350. FIRST PORTUGUESE RECORD OF THE GENUS ATRICHOPS VERRALL (DIPTERA: ATHERICIDAE) Rui Andrade Rua Calouste Gulbenkian 237 4H3, Porto, Portugal – [email protected] Abstract: The dipteran family Athericidae is, in Portugal, insufficiently known with only one species recorded to date. In this paper, the species Atrichops crassipes (Meigen, 1820) is recorded for the first time in Portugal increasing the number of species of this family in the country from one to two. Key words: Diptera, Athericidae, Atrichops crassipes, new record, distribution, Portugal. Primera cita portuguesa del género Atrichops Verrall (Diptera: Athericidae). Resumen: La familia de dípteros Athericidae está insuficientemente conocida en Portugal, de donde se ha citado sólo una especie hasta ahora. En este trabajo, la especie Atrichops crassipes (Meigen, 1820) se cita por primera vez de Portugal, incrementando el número de especies de esta familia en el país de una a dos. Palabras clave: Diptera, Athericidae, Atrichops crassipes, cita nueva, distribución, Portugal.

Parasites Vectors (2020) 13:461 https://doi.org/10.1186/s13071-020-04316-7 Parasites & Vectors RESEARCH Open Access Incompletely observed: niche estimation for six frequent European horsefy species (Diptera, Tabanoidea, Tabanidae) Dorian D. Dörge1*, Sarah Cunze1 and Sven Klimpel1,2 Abstract Background: More than 170 species of tabanids are known in Europe, with many occurring only in limited areas or having become very rare in the last decades. They continue to spread various diseases in animals and are responsible for livestock losses in developing countries. The current monitoring and recording of horsefies is mainly conducted throughout central Europe, with varying degrees of frequency depending on the country. To the detriment of tabanid research, little cooperation exists between western European and Eurasian countries. Methods: For these reasons, we have compiled available sources in order to generate as complete a dataset as possi- ble of six horsefy species common in Europe. We chose Haematopota pluvialis, Chrysops relictus, C. caecutiens, Tabanus bromius, T. bovinus and T. sudeticus as ubiquitous and abundant species within Europe. The aim of this study is to esti- mate the distribution, land cover usage and niches of these species. We used a surface-range envelope (SRE) model in accordance with our hypothesis of an underestimated distribution based on Eurocentric monitoring regimes. Results: Our results show that all six species have a wide range in Eurasia, have a broad climatic niche and can there- fore be considered as widespread generalists. Areas with modelled habitat suitability cover the observed distribution and go far beyond these. This supports our assumption that the current state of tabanid monitoring and the recorded distribution signifcantly underestimates the actual distribution.

This was at a time when we were moving towards the proposed atlas. However, assistance from the Biological Records Centre (Centre for Ecology and Hydrology) is getting things back on track. I would like to thank the staff there for their help. This is now a call-in for all Larger Brachycera records not already submitted to the Scheme. The plan was for you to have this winter to identify and collate, submitting any new/outstand- ing records by 31st March, 2008. However, as the L.B. Newsletter did not appear last time (Darwyn’s computer crashed and it was lost) you will need sufficient notice. Therefore, you will have another field season but all records are required by 30th September, 2008. Even if you onlyhave a handful of records of the commoner species,please send them as they all help to build up the picture of distribution and phenology; do not assume they will come via other sources, please send your original data. It is planned to make all the data available through the NBN Gateway in due course.
