could use some better pics that show the body more, but looks not unlike A. appensa.

Have you ever seen Argiope appensa? If so who ID them as A. appensa?
Could also be Argiope aemula (Walckenaer, 1842)...

if i had never seen one then why would i say the spider above looked like one? Here, look for yourself if you dont believe me.

A. appensa collected November 2005 on Maui, Hawaii

by judgeing on the abdomen pattern of your spider pandinus I would guess it is no appensa...

hi,
still my question: Who IDed your Argiope as Argiope appensa?
Who says itīs not a Argiope blanda (occuring from USA to Costa Rica), or A. trifasciata kauaiensis (also occuring on Hawaii)? Donīt get me wrong, I donīt say yours isnīt A. appensa - but it could be another Argiope, or do you know what the other 2 I mentioned look like?
And at least in the Asian region thereīre several species of Argiope, so I wouldnīt dare to say itīs a certain species --> Itīs an Argiope and that has to be enough (others can be IDed by pictures, maybe an Argiope with a "spiny" opisthosoma coming from Europe --> A. lobata; but this sepcimen :rolleyes: )
BTW.: I only wrote i could also be A. aemula, since thereīs a picture of A. aemula in Foelix, Biology of spiders. But I donīt know if the specimen on this picture is IDed right, who knows...

i had a friend at a university ID it using my dead specimen, a microscope, and an old key, so it is entirely possible i am wrong on this. i looked up the one you suggested, but think the pics may have been mislabeled as they looked nothing alike. I ID'd my specimen from visual, and my university friend agreed based of a few characteristics, i dont remember what. I also could find know other hawaiian species that matched.

hi,
as I wrote: Donīt get me wrong...
It could be A. appensa, nothing against that, BUT it could also be another species - and I donīt have enough experience with Argiope to judge this (have examined only 4 species). Normally you can distinguish them by their epigynium, at least at ultimate females. Thereīs a revision of the african species of Argiope, but thatīs useless for American or Asian species (as the title says :P ).
Could you ask your friend which key he used? Iīm really interested in getting my hands on some more literature about that genus.

Not sure what this proves or adds to the ID, but on Wikipedia, there is a section on the page listing of Argiope appensa that reads:

Synonyms:

Epeira appensa
E. crenulata
A. chrysorrhoea
A. crenulata
A. boetonica
Coganargiope reticulata
A. schoenigi

Seems to me that these could be relatively the same? But probably unlikely, but I am not an Argiope expert either lol. Needless to say they look beautiful.

hi,
since those are all synonyms theyīre not only "relatively" the same....the ARE the same ;)

Thanks :D

But why give different scientific names to the same species? Except for the people that have improperly classified the species, and then the population agrees on a change.

yeah, those are all previous/inaccurate names

hi,
thereīre synonyms because in former times less people compared their material to the type specimen of a species (mostly checked the literature - but not everything necessary was written --> see description of Avicularia avicularia ^^). Additionally some species have a large geographical range and can therefore differ in their color/pattern (--> see Pterinochilus murinus; all color forms have been valid species before the revision by Gallon).
Thereīre several reasons why a species is synonymized and most times it has nothing to do with improper examination or classification.
