Dr. Byers- thank you for havi

Dr. Byers- thank you for having vetted my submission and placing it within the "cylindricus species group". I am in hopes I again locate and hopefully acquire better sharp angle shots.

Ocyptamus dimidiatus

I looked at determined specimens of Ocyptamus cylindricus and Ocyptamus dimidiatus. This is not Ocyptamus cylindricus which is very similar to Ocyptamus fuscipennis but has a completely metallic abodomen. O. cylindricus is only currently known from Jamaica, Hispaniola, Puerto Rico and the Virgin Isl. This is actually Ocyptamus dimidiatus.

Kevin- thank you for having vetted my submission and opining the ID as "Ocyptamus dimidiatus", with your identification notes.

Dr Byers today placed it within the Ocyptamus Species Group of 6. It was the first time I have viewed this species and I was unable to digitally capture more angles for an ID. I will be on the look with hopes of acquiring better diagnostic digital files.

For info I am a 73 year old citizen naturalist that expends a good deal of time, 24/7 about our inner barrier Island attempting to identify the pollinators, mainly within a 3 1/4 acre Sparrow Field where I served for 4 years as the lead Landing's, Skidaway Island resident working a 150 yard berm containing our nectar sources we plant for our "Pollinators" I, through BugGuide.net have identified 39 "Diptera" to Genus, mostly to species. I am so appreciative of the scientist such as you that make this all possible. Thanks, Fitz Clarke in Savannah, Ga.

Kevin- I am most appreciative

Kevin- I am most appreciative for having the opportunity to review the discussion between yourselves, most interesting. I will do my part to locating and hopefully digitally documenting a diagnostic profile. I would love to establish a species. Best, Fitz

One species or two.

Sorry to dash your hopes. The question we are considering is whether O. antiphates and O. dimidiatus should be synonymized or not. Basically is there one species or two. Gil states he has seen intermediates between the to extremes represented by O. antiphates and O. dimidiatus.

Kevin- to a citizen scientist

Kevin- to a citizen naturalist/scientist this is fascinating. Thank you for informing me, "The question we are considering is whether O. antiphates and O. dimidiatus should be synonymized or not".

Most interesting, I look forward to your research results!!!

Probably O. cylindricus, but I'm not 100% sure.
