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?

uniserial

biserial

triserial

quadriserial header=[quadriserial] body=[In four rows<br /><img src='infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

If ac

header=[ac] body=[acrostichal setae<br /><img src='infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

are biserial, then it measn there two rows medially on the mesonorum. If dc

header=[dc] body=[dorsocentral setae<br /><img src='infusions//terms/images/no_image.gif' style='vertical-align:middle;' />] delay=[0] fade=[on]

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.
