I found this fly with the pictures of Swammerdamella sp. GC1. It has a larger abdomen and the marginal vein is longer. Could it be a second species of Swammerdamella (sp. GC2)? The second picture attached is of Swammerdamella sp. GC1 which has probably already been posted.

Hi Graeme !

The first picture is a female of Holoplagia guamensis (thorax broad, M1 angled near base, tarsi contrasting yellow, shape of terminalia). The second picture is a Swammerdamella indeed.

Interesting, the species Holoplagia guamensis, is not listed on ALA.

The Pacific catalog lists Micronesia as its range.

Thanks John, guess it got blown off course.

Holoplagia guamensis is a cosmotropical species. It is virtually present in all tropical areas of the world (even if not yet recorded). But if I remember well, Graeme, didn't you already submit a picture of this species taken in Townsville (Queensland) some months ago ?

Yes I did. Presumably a male due to the much smaller abdomen.
