Knowles (2009) provides guidance on the identification of this species within the T. figulus-group.
A small, black, very thin solitary wasp. Identification keys are given in Yeo & Corbet (1995), Lomholdt (1984) and Richards (1980).
A small, black, very thin solitary wasp, with a reddish mark on the fore leg. Identification keys are given in Yeo & Corbet (1995), Lomholdt (1984) and Richards (1980).
Trypoxylon figulus sensu Richards (1980) and Lomholdt (1984) is now considered to comprise three separate species. Knowles (2009) explains the history and provides guidance on the identification of the three species.
In 2006 Episyron gallicum was first recorded in Britain in a sand quarry in Bedfordshire.
This species is almost certainly extinct in mainland Britain, with most records from more than 100 years ago. It is placed within its own sub-family, Dinetinae, it being the sole species of this genus in Europe.
BWARS has not yet produced an account for this species. We anticipate completing the process of producing accounts for all British and Irish species by around 2014. Meanwhile, on this page you can find at least a provisional distribution map, any images BWARS has procured for the species and a list of known synonyms (names previously applied to this species). The work of mapping aculeate hymenoptera, plus describing their life histories, is the major activity that BWARS undertakes. Should you have an interest in recording and studying aculeates, you may like to consider joining BWARS and… Read more
Following on from the general comments about the difficulty in recognising the species within Pemphredon on physical characters, which is detailed in the account for P. lethifer, the name P. rugifer is similarly bedevilled with supposedly different entities (including one incarnation of P. lethifer!). Within the span of modern recording Richards, 1980, provides two names, P. wesmaeli and P. mortifer for the fauna of the British Isles and Ireland, these being separated by a supposed northern and southern distribution-… Read more
The genus Pemphredon has been the subject of much taxonomic debate regarding the aggregation or splitting of species pairs. This particular species has been subjected to more grammatical than taxonomic uncertainty, with Richards (1980) and Bitsch et al. (2001) referring to it as inornata Say, whilst Lomholdt (1984) opts for inornatus Say.
This is the sole British representative of the subgenus Pemphredon, a group which has had a little more taxonomic stability than the other subgenera (Cemonus and Ceratophorus).
