information available in book e.g. British Hoverflies (Stubbs & Falk), The
Natural History of Hoverflies (Rotheray & Gilbert) or non Syrphid-specific
literature e.g Manual of Nearctic Diptera because the terms tend to carry
over across families – though there can be some variation in
terminology.<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT color=navy size=2 face=Arial><SPAN
style="FONT-FAMILY: arial; COLOR: navy; FONT-SIZE: 10pt">But you are right, you
need to consider the genitalia in 3D and carefully look at how all the bits
articulate and become familiar with how certain parts are rigid whilst other
softer bits are prone to variation or damage. I dissected the genitalia of many
syrphid species in the past, esp Cheilosini, see Stubb & Falk
diagrams.<o:p></o:p></SPAN></FONT></P>

interested, I’m currently putting my syrphid photos (plus most other wildlife
groups) onto Flickr. Follow the link below – lots of nice images of some very
elusive species, plus their habitats. I’m about 40% there (families like
Tabanidae, Bombyliidae etc already finished).<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT size=2 face=Calibri><SPAN style="FONT-SIZE: 11pt">Does
anyone have a good standard work on male genitalia in Syrphidae?
</SPAN></FONT><SPAN lang=NL-BE><o:p></o:p></SPAN></P>
<P class=MsoNormal><FONT size=2 face=Calibri><SPAN style="FONT-SIZE: 11pt">I’m
always a bit frustrated with the lack of clarity when genital structures are
mentioned in keys or figures. </SPAN></FONT><SPAN
lang=NL-BE><o:p></o:p></SPAN></P>
<P class=MsoNormal><FONT size=2 face=Calibri><SPAN
style="FONT-SIZE: 11pt">Somehow, it’s often found obsolete to indicate whether
the drawing shows a lateral/ventral/dorsal view, and even just naming parts is
rather exception than rule: epandrium, hypandrium/hypopygium, surstylus,
gonostylus, paramere, aedeagus, aedeagal lobe, ... Many of theses things seem to
be taken for granted. </SPAN></FONT><SPAN lang=NL-BE><o:p></o:p></SPAN></P>
<P class=MsoNormal><FONT size=2 face=Calibri><SPAN
style="FONT-SIZE: 11pt">Identification guides go into great detail when it comes
to define a priori the structural sides of the thorax, wing morphology, etc. but
I have never seen this for Syrphid genitalia, nor how genitalia are modified
segments and how to “read” them. </SPAN></FONT><SPAN
lang=NL-BE><o:p></o:p></SPAN></P>
<P class=MsoNormal><FONT size=2 face=Calibri><SPAN style="FONT-SIZE: 11pt">Often
it’s called “genitalia” whereas it may refer only to a specific part of the
genital apparatus. That’s like showing a picture of a first tarsus and labelling
it as “leg”. Still, that’s pretty ok if you know that the distal part of the leg
is called the tarsus, but what to do if you don’t know where to find a paramere
if nobody told you in the first place where it’s located, especially when it’s
hidden by some other structure? </SPAN></FONT><SPAN
lang=NL-BE><o:p></o:p></SPAN></P>
<P class=MsoNormal><FONT size=2 face=Calibri><SPAN
style="FONT-SIZE: 11pt">Interpreting such label-less 2D figures out of their
structural context when confronted with a 3D specimen under a stereomiscroscope
and linking this to a key can be really frustrating. </SPAN></FONT><SPAN
lang=NL-BE><o:p></o:p></SPAN></P>
<P class=MsoNormal><FONT size=2 face=Calibri><SPAN style="FONT-SIZE: 11pt">I had
hoped to find a pdf of CL Metcalf’s work “The genitalia of male Syrphidae”. If
anyone has it, I would be grateful to receive a digital copy. Other suggestions
are welcome as well. </SPAN></FONT><SPAN lang=NL-BE><o:p></o:p></SPAN></P>
