Can anyone start me off on this doli please. I would also like explained the idea of uniserial and biserial acrostichals as used in the RES handbook key?

Uniserila = 1 row. Biserial = 2 rows. This looks like a female Dolichopus - start there... |

Phil, thanks, I got that, but over the whole insect, does it then mean 2 rows = uniserial and 4 rows = biserial? |

If ac are biserial, then it measn there two rows medially on the mesonorum. If dc are biserial it measn that there are two rows of dc on each side of the mesonotum, so strictly speaking four rows in total.

Paul - my confusion was that uniserial ac (I'm assuming a single row along the centre-line) seemed an unusual arrangement to find and I wanted confirmation as I have not encountered a uniserial specimen yet. Thank you for your clarification. |

I forgot to mention that the fly keyed out comfortably to Dolichopus claviger - yellow femora, pale post occulars, squamal fringe mixed colours and various leg bristle conditions. Thanks to Phil Withers for the original hint. |
