Hi, can someone help with this horsehair worm? Found under a stone. It was some 6 mms long.

Thanks!

Dear pwalter
Could you add a detailed photo of only these posterior lobes from both sides (ventral and dorsal)? If there is a true third lobe in between these larger lateral lobes, than it is most likely the female of Paragordius stylosus. If not, than it is a male specimen of 6 genera. Than you have to check if there is a crecent present at the base of these lobes. If so, than genus Gordius, if not, than 5 other genera are possible still. Also diagnostic are the absence or presence of spines or bristles in front of the lobes. Within Gordius, 18 species are described in Schmidt-Rhaesa (1997), many of them may occur in Hungary.

:o
the first thing that came into my mind: did he collect the carabid beetle or the horsehair worm?
By the way, one of the largest horsehair worms is that of Gordius villoti reaching 91 cm (female). Gordius has the largest representatives, 20-35 cm is not unusual.
and yet another thing: these white spots on the cuticula or not diagnostic!
