Some sawflies of the European Alps and the Mediterranean region (Hymenoptera: Symphyta)

Three new species of the Macrophya maculitibia group (Hymenoptera, Tenthredinidae) with a key to known species from China

“…OCL The distance between the lateral ocellus and the occipital carina, or the hind margin of the head where this carina would be if it were developed (Benson 1954). OOL The distance between the eye and the lateral ocellus.…”

A Provisional List of Swiss Sawflies (Hymenoptera Symphyta)

“…It is as well to note that the galls of P. tuberculata and P. joergensoni are probably indistinguishable from those of pedunculi, so that certain identification of this species from its gall is not possible. Pontania arctica was treated as a synonym of crassipes by BENSON (1960) BENSON (1960, loc. cit., supra).…”

“…chambersi. Species of Pachynematus related to rumicis have been discussed and keyed by BENSON (1962). P. gehrsi is associated with Polygonum bistorta, P. lacteipennis with Rumex alpinus.…”

“…The main sources from which I took records are the following: BENSON, 1955BENSON, , 1960BENSON, and 1961DIETRICH, 1868;LISTON, 1980;STECK, 1893. Numerous other records were abstracted from diverse papers and monographs by various authors.…”

“…The diversity and richness of the fauna, even as it is known at present, is obvious, and is shown well by this list. BENSON (1961), in his introduction, probably gives the most sensible treatment of the elements that go to make up the Swiss sawfly fauna. He divided the alpine fauna into the following sections : species with arctic-alpine ranges, those that are boreal and subalpine, species that are endemic or that have eastern rather than northern distributions, and also a small group of sawflies that are apparently confined to Scotland and the Alps.…”
