In Africa less candidates ...
The longest is Macrotoma hayesi (up 135 mm)
followed by Goliatus (more than 110 mm)
and some species in the Acanthophorini up 100 mm (genera Tithoes and Anthracocentrus)

Yes Tom, not so complicated .... litterature is full of confusion and complicated but the field situation seems clearer. I also had some difficulties in the past to find the answer (because of litterature), it seems now the situation is clearer at least the better existing for the congolese ones. I ...

As presented in drawer.JPG
Both reversed.JPG

first is gallienus, second is mechowi

the true is not complicate. - the verso HW margin of gallienus is black and well marked (separated from base and discal area light brown) - the same area in mechowi is of the same color as the rest of the wing except nervures and internervures that are blackened. In mean, yellow HW band is more regu...

Diptera, Brachycera from Kenya Kitui region (dry zone)

Does anyone knows what it is ?

thanks, Thierry

what are the localities of these Tithoes ?
yes Pierre is right, 1 and 3 are confinis, but 2 can be frontalis or maculatus (two close sp, locality may be important as photos are not always sufficient)

I use this site sometimes for my groups. It is true that nomenclature is not at the top despite being at good level. Many of the corrections I made (quite all) were followed and sometimes these corrections have been made in the database following my remarks. It is something dynanmic. What is amazing...

Does anyone have info for going In Saudi Arabia espacially about the possibility to hunt there, permits, how to go in choosen localities and agnecies to travel, etc.
thanks, Thierry

The difference with hybrids, at least between species, is that the offspring are normally infertile; but with CRISPR modified specimens their genes should be transmissible. These should never be allowed into nature, just as live specimens of non-native species and subspecies should never be release...

Adam.

Which one ? "The genus Colias" published in 2012 or a more recent one ?

May be Bob can inform why ponteni / imperialis seems not illustrated or treated in the book ?

Hewitsonia intermedia

the true can be diverse. D'Abrera's work is just to compile an illustrate catalogue based on his opinion (that seems sometime strange an unscientific). Having had discussion with him, I can tell that his predicator function and creationist thinkings were more important for him. For Hecq the problem ...

Pseudacraea lucretia gamae Joicey & Talbot, 1927. Two males from Principe Island. This island is off the coast of western Africa. I have seen this listed as a species (Pseudacraea gamae), rather than a subspecies. This is in “Butterflies of the World” Part 16. Nymphalidae VII, Pseudacraea. By J...

lucretia at least seems to be trying to mimic Amauris species.

may be that it looks different with a non human vision ?

That's not preussi , which has a differently shaped sub-apical band & does not have a purple sheen. Looks much more like E. uganda too me, but of course this genus is a difficult one to ID. Thomas, the picture is saturated with a red component marked. The purple effect may be not not so strong ...

P. lucretia (RDC, Katanga) male aberrant (despite may be be gynandro but forelegs and genitalia normal)

P. lucretia gynandrmorph (RDC, Katanga), asymetric and distorted male genitalia and forelegs female

never two same specimens, seasonal variation, geographic variation, color forms, etc. This si not for pathologic collection I intend to study them one day (I have yet wrote 3 small papers and one new sp, Colotis hecqi)
