H. fenestratus

A synonym of Lapsus tritis. I should have a guide published soon at Insecta mundi.

Heteroceridae

very tough to tell the currently recognized genera apart based on pix, but someone may eventually recognize the species...

coxcal lines -

need to start with the meso and meta-postcoxcal lines. See recently added breakdown of genera on the family info page, and/or line drawings (of the lines) in Am Beetles. Size is also fairly telling of genera groups.

Now I"m going to go too far - Given the "pairs" of spots I think I see behind the middle, and the suggestion of lines reaching the base either side of the scutellum, I'd suggest this is Lapsus tristis - dorsal coloration is fairly unique to this species. see

Tim - I've added another ima

Tim - I've added another image of this Beetle - actually a cropped images of it's tarsal area. You're image doesn't show the comb / spikes that I've got in my image. Maybe this will help. Thanks for your help so far.

thanks,

not sure if the comb is there on Jim's image and just not visible or if it's not there. A comb can just be seen on my (poor - old technique) ventral image of the same species. Or perhaps its an male/female thing.

Anyway, the real (external) diffences used in the keys are the post-coxcal lines and elytral patterns.
