Male genitalia - ventral. Is this the view that's needed and is this sufficient magnification?

Thanks Evi I've just heard back from Peter Chandler (I sent him the images) and he says it's M. dziedzickii. This is M. dziedzickii, an uncommon species for which the only rearing record is from under loose birch bark bearing the resupinate fruiting bodies of Scytinostroma galactinum in Finland (Jakovlev 2011). I presume there was no likely host apparent?
M. ornata is easily recognised by having a series of separate brown spots in the preapical wing band. Edited by bioimages on 09-03-2020 20:35 Malcolm Storey www.bioimages.org.uk (Two wings good, four wings better!) |

Many thanks for information. Here Chandler comparison of lunata and dziedzickii (=obscura in text part). http://www.online..._gnats.pdf Chandler description on page 90: Lunata has the apical spine markedly curved and 7-8 lateral spines. Dziedzickii has the apical spine nearly straight and only 4-5 lateral spines. This has nearly straight apical spine so yes dziedzickii. This has 6 lateral spines in photo => dziedzickii can thus also has 6 lateral spines. BR Esko |
