I agree with Nikita. It is Atylotus, but I'm not familiar with all the species, so can't say which one.

Hi Louis I've been having another look at your pictures, and wonder whether it could be a variety of flavoguttatus? In any case, it would be worth trying to catch a specimen to find out exactly what it is. Good luck!

1-eyes pubescent, even short.....2 - bare, or short, only visible with big "zoom", ..3 2- front callus big and united, brilliant colour... A. venturii - callus small, separated or without them, black abdomen..A. latistriatus 3- vertex: 1 row of short white hairs...4 - vertex: 1 row of long yellow hairs, femora grey, black abdomen with 2 longituninal stripes.. A. flavoguttatus 4- yelowish species...5 - greyish species...6 5- well developed callosit..(callus)..A. loewianus - callus small... A.fulvus 6- femora yellow, abdomen with black stripes..7 - femora grey, abdomen grey-green, reddish flagell.. A. rusticus 7- black abdomen with 2 yellow stripes... A. agrestis - abdomen yellowish with 4 dark stripes... A quadrifarius i?m not the one to tell how much diffrerent it could be a variety, but by the pictures of my book, flavoguttatus clearly has a almost black abdomen with just 2 narrow paler stripes i haven?t written all the details of the keys, just a few, but if anyone?s intersted i can complete the text |

i don?t know in which part of spain quadrifarius has been recorded, but in case of colder weather it?s perfectly possible in the north (Galicia, Asturias, Cantabria, Euskadi...) the "green" Spain, with atlantic weather ???? |

Paqui - I think what bothers me about quadrifarius was the colour of the femora in this specimen (too dark?) and the size of the frontal callus (too small). But I agree the abdomen colour is wrong for flavoguttatus, too. I guess we need more specimens to understand better the extent of variation in these species. Best wishes Tony ---------- Tony Irwin |

I'd say that you are correct - it is the male. But I'll leave it to Paqui to say what the species might be. Maybe I'll join in later!

I've just been comparing the pictures with some old specimens of Atylotus latistriatus, and I feel sure that they are pale examples of this species. In Britain, latistriatus is a saltmarsh species, but elsewhere it occurs in different habitats. Is anyone famiiar with latistriatus in the field? (I hope to get bitten by some next week!)
