Anasa andresii - Catorhintha apicalis

Anza-Borrego Desert State Park, San Diego County, California, USA
March 20, 1996
Size: BL ~ 12 mm

Found in Hoberg Canyon. We also saw a mating pair of this bug in Wishbone Plant (Mirabilis californica, Four-oclock Family, Nyctaginaceae) in Hellhole Canyon, 27 Mar 2006.

I've been trying to identify this bug to species for over ten years. California has only two species, A. tristis and A. andresii. This bug has white dots on it and some yellow on
the antennae that differ from all A. tristis I have seen. But I've had no success in finding any information on A. andresii. Until I checked BugGuide! Posting # 240125, Anasa tristis, includes info that A. andresii has the fourth antennal segment yellowish. In my photo at least part of the antennal segment is yellowish. Probably it is A. andresii?

Update: yes!

Catorhintha apicalis

THanks you so much, v belov and T. J. Henry for correcting the identification of this bug. I'm delighted to learn the correct species.
What is of special interest to me is that we found this bug mating on Wishbone Plant, Mirabilis bigelovii, in the Four O'Clock Family. (Anasa andresii, its previous name, is in the Squash Bug group.)

Here in Colorado where I live, on Sept. 5 of this year, I found a bug very similar to this bug, also on a Four O'Clock, Oxybaphus hirsutus. This Colorado bug has just been identified as Catorhintha mendica (#720890), a known feeder on a widespread Four O'Clock known as Wild Four O'Clock.

Ten years?

I'm not sure why there is confusion about the ID here. If you know that California only has two species of Anatis, then this must be A. andresii because the descriptive key given by Baranowski here: http://fulltext10.flca.edu/DLData/UF/UF00000092/file76.pdf clearly states that the "fourth antennal segment yellowish or orange, at least distally". None of the other four species in the key shares this character. On the off chance that one or two of the remaining US species has this same antennal feature, then there is a slight chance that we might be incorrect, but for now, I would create a page for this species and move on.

Anasa andresii

I wish I could open your link to Baranowski, but my dial-up is too slow. Will have to wait till I can get to the CU library. But your posting gave me the clue:" The fourth antennal segment yellowish or orange, at least distally." Those last three words are the verification I needed. Thanks so much for providing them.

Actually, I've never known whether this was just a variation of A. tristis or not. Did those five tiny dots and a little color at the end of the 4th antennal segment matter? I'm glad to find out they do matter!

Info

I added some more links to the info page if anyone wants to double check the ID.

Question on Antennal Character?

I was grateful to find the good info here while trying to confirm the species ID for a recent Anasa post of mine.

Just wanted to mention that, in comparing the BugGuide images of Anasa andresii with those of Anasa tristis, it seems to me that the pale (yellow?) distal tip of the 3rd antennal segment in A. andresii is a more conspicuous distinguishing character than the (shorter and more inconspicuous) pale yellow or orange distal coloration of the 4th antennal segments. I'm wondering whether this is just a coincidence (being based on comparison with only 3 A. andresii BG posts...all from southern California), or whether it may hold in general, perhaps indicating an error or shortcoming in the keys?
