Hi Robert. I think - Heleomyzidae, not Suillia. Tree bark is suitable place. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Pseudolyciella (Lauxaniidae). A few years ago this would've been P. pallidiventris, but this species has since been split into a group of closely related species determinable only by male genitalia.

IMAO: There needs to be some work done on that species complex. The species can be separated on male genitalia only (no female charcters mentioned anywhere at all) and when long series are collected, usually you will find several species and a few intermediate specimens. For the moment Pseudolyciella pallidiventris group is what these specimens can be classified as.

I am wondering if you can see any genitalia at all with these tiny flies  For the moment I'll call them Pseudolyciella pallidiventris in my collection/excursionlist. Thanks a lot, robert, |

Acutally, for the group of Lauxaniidae, I think they are slightly above average in size. And once available, the genitalia of species in the Pseudolyciella pallidiventris group are quite easy to prepare and view.
