Cartoon name for new species?

by Jshuey » Mon Mar 25, 2024 1:51 pm

I have a bug that I'm about 90% sure is a new one. It's in a genus (Aguna - Hesperiidae) where adults are mostly indistinguishable from one another, until of course, you dissect them.

Well, I've dissected about 70 of them recently, and have stumbled on three definite new species, plus this one. Turns out that there 13 (or 14) species present in NE Peru - pretty amazing! It's distinguishing characteristics are the little sclerotized knob on the harp and the gear-like ampulla that looks exactly like Lisa Simpson's hair-do that sits on top of the harp. I suggested to my wife that I name it after Lisa - and she thinks it's a stupid idea. Something like lisimpsonia.

What do you think? I'm still not entirely convinced that it is new - it looks a lot like A. spatulata. But I have three of the potentially new ones, and seven spatulata - and the differences are very consistent (but minor).

Actually both the 2009 and 2023 classifications are based on DNA analysis to build a tree. Trees have been built from the results of DNA analysis since the 1990s, but sequencing techniques have improved considerably.

I am not sure I agree with these 'rules' exactly ;) , particularly in relation to generic classification.

Separation of two or more groups into two or more genera is basically subjective as long as each genus is monophyletic (all species in the genus are derived from the same common ancestor). This was the problem with Charaxes and Polyura, since the Polyura clade is nested within Charaxes.

There are two ways to solve a problem like this and neither is actually 'right' or 'wrong':
1. Include the whole clade in a single genus
or
2. Separate each sub-clade into a different genus so that each one represents a branch containing species which are all derived from a common ancestor.

So '1.' was the method used when Polyura was included in Charaxes and '2.' was the solution adopted by Bouyer (2023) to maintain Polyura as a separate genus, which at the same time necessitated separation of other species groups into different genera.

Generic classification is somewhat different to that of species in that it uses different criteria. The separation of species can be tested in different ways which hopefully give a 'same/different species' result.

There is a "Make an offer" button. Nobody will pay so much for elephenor, don't worry.

There are 2 important rules in taxonomy :

#1 : you have to follow the latest publication. So in this case Bouyer 2023. (We now have scientific techniques like DNA analysis we didn't have in 2009).
#2 : InsectNet members are always right, so once again, you have to follow Bouyer 2023 (@africaone on this forum). :lol: :lol: :lol:

Thanks to everyone who answered my questions, greatly appreciated.
Now I'm having to ask this next question knowing that it will have two different types of viewers.
So, what I'm querying is we have splitters and lumpers exemplified by Thierry Bouyer in his paper on Charaxini 2023 and Kwaku Aduse-Poku, Vingerhoedt and Walberg 2009.
All eminent in their fields of study.
All highly respected authorities on Nymphalidae.
So, who is correct?
Both views are at opposite ends of discussion on what makes up the seperate genus of charaxini.
Any suggestions???

Now I know where it was described I was able to make a copy of the photos as I have the book.

My thanks for your help, i dont suppose you have access to a photo of the male of this ssp?
I know thee female and really would like to compare with nominate.

Euxanthe spp. (which are also Charaxinae) have larvae with similarly elaborate head capsules -

INTRODUCTION: Tiger beetles have been called 'the butterflies of the beetle world' due to their great beauty and the fact that there are numerous wonderful field guides with superb photographs or drawings as well as distribution maps. These factors make tiger beetles popular with many naturalists who in turn contribute much important data to scientists. The Austin Butterfly Forum is most pleased to have Dr. Barry Knisley speak to us about aspects of his life of tiber beetle research and conservation.


TITLE: TIGER BEETLES; BIOLOGY, CONSERVATION, AND DIVERSITY IN TEXAS

BIO: Dr. C. Barry Knisley, Wornom Professor Emeritus of Biology at Randolph-Macon College, received a B.S. in Zoology and Entomology from Penn State University and an M.S. and Ph.D. in Entomology from Rutgers University. He began his 40 years of teaching in liberal arts colleges with the first 10 years at Franklin College of Indiana. With the opportunity for teaching courses more related to his area of expertise and pursuing research on tiger beetles, he joined the biology department at Randolph-Macon College in 1979. He has taught entomology, ecology, and a field course in desert biology in the southwest and tropical biology in Costa Rica. Most significant was his development of a field biology program and a requirement for biology majors to conduct an independent research project. His 50 years of research has focused on the biology and conservation of tiger beetles, resulting in over 80 co-authored papers and 5 books (Field Guides to Species of the South Atlantic States, 1997, and Field Guide to Species of U. S. and Canada, 2015, Tiger Beetles of New Mexico, 2023). He has conducted most of the research for 4 of the 5 tiger beetles currently on the Endangered Species list and continues to be active in tiger beetle conservation throughout the U. S. A primary goal of listing tiger beetles has been to insure the protection of significant natural areas for the tiger beetle and other species. He has worked closely with various government and private groups on tiger beetle conservation. His studies have been funded by the USFWS, Maryland DNR, National Park Service, BLM and various private conservation groups. Much of his research since the late 1980s has involved monitoring and research on the Northeastern Beach and Puritan Tiger Beetles in Maryland and Virginia. He was one of the founding members and past president of the Virginia Natural History Society.

While on the topic of Charaxes/Polyura - the larvae of these butterflies are known as dragon-headed caterpillars; here are some nice photos of the larva of P. hebe -

It is worth mentioning that Mt. Dempo in southern Sumatra does seem to have some different subspecies of several butterflies compared to other parts of Sumatra. It is possible that someone (Japanese?) described it, but I am not very familiar with Charaxini nomenclature.

Unfortunately I am not an expert on anything other than Papilionidae, but Wikipedia only lists two subspecies at https://en.wikipedia.org/wiki/Polyura_dehanii

Toussaint published several papers on Polyura about 8 years ago, and he only listed two subspecies too.
Note the correct spelling of the species name is dehanii.

Yes, but what he did was split Charaxes (s.l.) into several different genera, thus also conserving Polyura as a genus. As a result many African species have changed genera, for example C. lydiae became Ydeali lydiae.

The paper is Bouyer., T. 2023. The genera of the tribe Charaxini (Papilionoidea, Nymphalidae, Charaxinae). Metamorphosis, 34: 59–78.
Abstract:
The systematics of Charaxini is revised. The three historical genera are confirmed: Charaxes (Ochsenheimer, 1816); Polyura (Billberg, 1820) and Euxanthe (Hübner, 1819). The genera Eriboea (Hübner, 1819) status rev.; Zingha (Hemming, 1939) status rev.; Viridixes (Bouyer & Vingerhoedt, 2008) status rev. and Euxanthe subgenus Hypomelaena (Aurivillius, 1898) status. rev. are reinstated. Three new genera are described: Laodice genus nov. with the type species Papilio lycurgus (Fabricius, 1793); Setechin genus nov. with the type species Charaxes nichetes (Grose-Smith, 1883) and Ydeali genus nov. with the type species Charaxes lydiae (Holland, 1917). A key to the nine genera is provided.

The paper is available online.
