Chilocorus? - Hyperaspis

Moved

Interesting

I'm currently working on a Hyperaspis key, and these red-spotted guys from the west are strange except H. haematosticta. All known species with this pattern are strictly eastern in distribution. Either its a species I've forgotten about, a range extension, or a new species...

isolated introduction, maybe?

Sometimes, if a species that can be easily identified is in a completely atypical location, I suspect that it just hitchhiked in an agricultural shipment.

Although this certainly can't be ID'd to species, it does appear a good fit for the signata or binotata groups in the east.

Moved from Ladybird Beetles.

I'd say Chilocorus, west coast version

Very plain "face" points in that direction. Check Cindy's and Lynette's post.

I politely disagree.

Chilocorus has a completely different body shape, and is larger. I would bet this is a species of Hyperaspis. Nice find, likely a new species for the guide.

agree with Eric, not Chilocorus

I believe there's actually several Hyperaspis species black with two red spots, including these guys

. I'm away from my copy of Gordon's ref. but I'll try to get you a species name or two when I get back.

… Tim Moyer, 14 July, 2008 - 3:25am

I stand corrected.

Well, more accurately, I sit corrected.
(I need to be more accurate!)

… Ron Hemberger, 14 July, 2008 - 10:32am

Thanks Eric and Tim!

No sweat, Ron - I've made more ID goofs on this site than I care to remember.

Will move to Coccinellidae until Tim gets a chance to look in his reference text, then?

… Ken Schneider, 14 July, 2008 - 10:53am

not sure,

after looking though Gordon's ref. and factoring in your location, I wasn't able to some up with any clear fits (or even any 'could be's). There are several eastern Hyperaspis species that could fit, but they're no where near your local. Hopefully an expert will visit and help with this one. In the mean time, please post any addition images you might have on this one, especially ones confirming pronotum and face are entirely black.

… Tim Moyer, 18 July, 2008 - 11:32am

Thanks again, Tim -

posting two additional images today. Not sure they will help, but just in case...

In case it's useful, here is the list of all the Hyperaspis sp. in CA from the Santa Barbara NHM CA Beetle Project - most of these don't have an associated image in their database unfortunately:

Coccinellidae Hyperaspis annexa LeConte
Coccinellidae Hyperaspis arizonica Dobzhansky
Coccinellidae Hyperaspis bensonica Casey
Coccinellidae Hyperaspis borealis Dobzhansky
Coccinellidae Hyperaspis chapini Dobzhansky
Coccinellidae Hyperaspis cincta LeConte
Coccinellidae Hyperaspis connectens (Thunberg)
Coccinellidae Hyperaspis disrupta Dobzhansky
Coccinellidae Hyperaspis dissoluta dissoluta Crotch
Coccinellidae Hyperaspis dissoluta nevadica Casey
Coccinellidae Hyperaspis excelsa Fall
Coccinellidae Hyperaspis fastidiosa Casey
Coccinellidae Hyperaspis gemma Casey
Coccinellidae Hyperaspis inflexa Casey
Coccinellidae Hyperaspis jovialis Fall
Coccinellidae Hyperaspis lateralis Mulsant
Coccinellidae Hyperaspis leachi Nunenmacher
Coccinellidae Hyperaspis limbalis Casey
Coccinellidae Hyperaspis longicoxitis Nutting
Coccinellidae Hyperaspis mckenziei Nutting

ID -

not sure I comprehend the expert's thoughts on this one completely, but it sounds like it's safe to move to Hyperaspis?? If anyone knows of a key to Western species of Hyperaspis, let me know...

… Ken Schneider, 12 August, 2008 - 11:22am

That's what I get out of it, too.

Shifting gears, these lists drive me nuts. There are so many names and so few differences shown and/or cited. Grrrrr!

… Ron Hemberger, 12 August, 2008 - 5:51pm

Thanks, Ron!

Moving to that guide page.
