Hi, This probably is a Tachydromia sp.[Tachydromia umbrarum, I think] from North-Norway,Harstad kommune, Fauskevåg store (10 m), seen the 24.june 2019. Habitat: Garden. distribution/Bahavior: Very common, running quickly on the walls of the house. size: minute (no more than 4mm) Is identification confirmation possible? Thanks in advance, Rune Kristiansen Edited by runetk on 14-11-2021 12:44 |

Hi Rune, the behavior is exactly what I saw! But umbrarum should have a yellow band in the middle of the front femora (smithi?). Hope, this helps a bit, Eric |

Thanks Eric  I think this family is very undocumented in norway and sweden duo to its size. No recent findings for my area Troms in north-norway. Still few for norway and sweden in general. mostly t.umbrarum.. the others need probably genitalia samples. For all i now it can be an undocumented species  But due to the advance in macro technology with cameras this will change. Macro photography is cool and really rewarding. This site is extreamly important with its great gallery of different species. NB: t. smithi is not an option in artsobservasjoner.no (so not recorded in norway)  |

I cannot see any thickened, strong dorsocentral and scutellar setae. That would rule out umbrarum and smithi. Other characters might leas to excisa but a specimen is required for any certainty.

Thank you so much for taking your time and giving me such a thorough explanation Paul. . As I expected, a specimen is needed. I will send "one" to a lab in Tromsø or oslo. So we can have certenty regarding this common specimen in the north. Edited by runetk on 04-07-2019 13:54 |

I cannot make anything more of them then dark specimens of umbrarum, even after genital disscetion, but I will make a more thorough comparisson later.
