A fairly intensive few sessions on data-gathering throughout the UK and Europe and even a brief foray into the Nearctic has led to both an improvement in Open Data contributions and biogeographical perspectives. NBN Atlas now has the Open Data, up from 5373 to 6409 as shown opposite. Clearly I'm able to do the maps long before the data upload gets processed (takes about a month), starting with a few selected ones for this newsletter. The website gets those maps too, check it and you'll find both old and new ones. The European Atlas gets an update too, this time with points distributions rather than being country-based (as in my Researchgate preprint at https://doi.org/
Phytomyza orobanchia Kaltenbach, 1964, a leaf miner fly of Orobanche spp. and Phelipanche ramosa (L.) Pomel, is reported as a species new to Slovakia based upon dates from 50 localities from lowlands after as much as alpine location.
ABSTRACT - The study of more than 1300 specimens updates the situation concerning the Diptera of the Psilidaefamily. A list of the French fauna (continental) is proposed, accompanied by illustrated determination keys for the six genera and 37 French species (with five other potential species). For the genus Chamaepsila, the proposed key is provisional. The illustration of the genitalia of Chamaepsila villosula male is however unpublished. A few elements of ecology (notably chorology and larval habitats) of the species cited are also detailed from elements collected in the literature.
RÉSUMÉ - L’examen de plus de 1300 spécimens actualise la situation à propos des Diptères de la famille des Psilidae. Une liste de la faune française (continentale) est proposée, accompagnée de clés de détermination illustrées des six genres et des 37 espèces françaises (avec cinq autres espèces potentielles). Pour le genre Chamaepsila, la clé présentée est provisoire. L’illustration des pièces génitales du mâle de Chamaepsila villosula est cependant inédite. Quelques éléments d’écologie (chorologie et habitats larvaire notamment) des espèces citées sont également détaillés à partir des éléments rassemblés dans la littérature.
