Some Neotropical Siphonini

Some Neotropical Siphonini
Today I went through some of the specimens in my World collection that had been labelled under the siphonine genera (Actia, Borgmeiermyia, Ceromya, Pseudosiphona etc.). Here are some photos: The Erythomelana is only “possibly” at the moment … it keys to that but I have never seen the genus so I have asked Monty Wood ...

My first stacks 7

My first stacks
Yesterday Malcolm Storey (bioimages.org.uk) brought over some new equipment he had just bought for photo-stacking, along with a ‘kit’ including a spare dSLR (3MP Nikon D100) and macro lenses. The real star of the equipment is Malcolm’s new StackShot – an automated system for racking a camera through pre-defined focus points and taking the photos ...

A new arrival from Peru!

Today I received a very exciting parcel of peruvian tachinids from John Smit and Menno Reemer. The samples were taken during the last half of 2009 in the Sachavacayoc Centre, Tambopata river region. This is a very species-rich part of the world with a very interesting fauna to me. I will probably take another few ...

Pheeewww! I’ve just finished sorting batch 3

Pheeewww! I've just finished sorting batch 3
I like to split the processing of Malaise trap samples into several distinct phases. The first phase is to empty the tubes of insects suspended in alcohol into individual tupperware trays and then work through them, splitting out the groups that I am interested in (mainly tachinids) and that I collect for friends. The tachinids ...

fg-taxon #63 (close to Borgmeiermyia sp.)

(photographs to follow) At first glance just a small, black & grey-dusted tachinid but this taxon has hidden depth. The most distinctive feature when sorting is the orange coxae on all legs – a quite unusual feature. The male genitalia are also quite easy to spot, being quite rounded & hairy often with some orange-colouration. ...

fg-taxon #52 (Borgmeiermyia sp.)

fg-taxon #52 (Borgmeiermyia sp.)
This is the other half of a pair of very similar taxa (see also fg-taxon #53). This one has a much longer antennal segment 3 and less thoracic dusting. And here is a rather spectacular specimen, which is presumed to be the female of this taxon. Note the swollen fore basitarsus; large piercer and opposing ...

fg-taxon #53 (Borgmeiermyia sp.)

fg-taxon #53 (Borgmeiermyia sp.)
This is one of a pair of very similar taxa (the other is fg-taxon #52) – very small in size (3-5mm), with black body, orange legs and plain wings. This taxon has a shorter antennal segment 3 and a little more dusting. EDIT (Monty Wood 26/9/2010): This is a Borgmeiermyia sp. – but not one ...

Borgmeiermyia brasiliana (fg-taxon #11, ‘feather-face’ #2) 3

Borgmeiermyia brasiliana (fg-taxon #11, 'feather-face' #2)
This is a male of the second taxon to exhibit the highly modified antenna-3, shaped like a feather. All specimens of this taxon are between 4-5mm long and so the photographs are of quite low resolution. However, you should be able to see: the distinctive black body with golden dusting pattern; completely orange legs; slightly shaded ...
