UPDATE: The individual in you

UPDATE: The individual in your photo and the similar specimens in the collection are actually in Scopaeus, but not the same subgenus as the ones already in the guide (the ones in the guide are more delicate, with a more pronounced anterior extension of the pronotum).

Page structure

If you know which named subgenera this image and the older images belong to I can create pages to separate them.

Do you know if this is an undescribed species?

I think it's probably best to leave Scopaeus as an undivided entity. Scopaeus has never had a modern revision so the current subgenera probably won't contribute much to the guide, just add confusion.

Moved from Eustilicus tristis.

Moved the images to Genus.

Hi Scott, Upon study of mo

Hi Scott,

Upon study of more specimens in the collection at Guelph, I've realized there are specimens that key to Eustilicus tristis that certainly ARE NOT this species. These specimens are much slenderer and match your photo exactly (I collected them all from Virginia, and one from Indiana). So I think for correctness's sake, we should move this to the genus level. This is probably an undescribed Eustilicus species or related genus.

Cheers,
Adam

Thanks V

I'll move it along then.

I think this is one of the relatives

Rugi*lus has coarse sculpturing on the head, while this does not. Dark, stiff setae are apparently missing from this specimen so it must be a species of Eustilicus.

Vital statistics

I made a page for the genus. Please post anything that belongs on the genus page -- ID, range, habitat, etc. All I can easily find is that the genus was defined by Sharp in 1886. Neither nearctica nor itis.gov recognizes the name.

… John F. Carr, 2 February, 2009 - 5:36pm

The name is currently valid.

The name is currently valid. The whole Paederinae is undergoing a generic revision at the moment, so Eustilicus may indeed be synonomized or moved. Sometimes the old Stilicolin*a is used instead (a Casey name). They are found in moss and moist litter sometimes in riparian zones. There is one species in our area (NE NA), tristis. Herman (1970) did a revision of the genus: http://digitallibrary.amnh.org/dspace/bitstream/2246/2622/1/N2412.pdf

I believe these are uncommon relative to Rugilus.

Synonyms and species

1. Is St. Casey 1905 a junior synonym of Eustilicus Sharp 1886 that was not recognized as such until recently?

2. Is it safe to call this individual E. tristis? Based on a quick scan of the paper you cited the habitat or range is wrong for the other species. (This was found in leaf litter in Virginia.)

… John F. Carr, 2 February, 2009 - 6:44pm

Hi John, 1. I believe thi

Hi John,

1. I believe this is the case. I think a lot of names were sorted out when Herman wrote his 'recent name changes in Paederinae' paper in 2000(?).

2. We can definitely call this tristis, there simply aren't any other options :). Quite nice to have this on bugguide, I've never seen one.

thanks, Adam!

it's so good to have you around

Thanks V, Adam

Looks like a new genus page will be needed.
