Entomologists describe a new species of the Tiger swallow (genus genus) Papirio) From eastern North America.
Papilio Sorstian: (a) male, holotype and (b) female, arotype. Scale bar – 10 mm. Image credit: Derotler et al. , doi: 10.3897/zookeys.1228.142202.
Papirio It is a large genus of swallowtail butterflies within the family Papillonidae.
The only representative of the Papillionini family, the genus contains about 200 scientifically recognized species.
Newly identified members of the genus Papilio Sorstianbelongs to North America Papilio Glaucus Species group.
” Papilio Glaucus The group is a model research system for insect evolutionary biology. ” Dr. B. Christian Schmidt Arknides, nematodes and colleagues wrote on paper from the Canadian National Insect Collection.
“Recognition and boundaries” Papilio Glaucus and Papilio canadensis Three decades of study in speciation, host plant adaptation, hybridization, and molecular evolution have been conducted as a pair of classical sibling species. ”
“Recently, we have discovered a third species. Papilio appalachiansisprovided unprecedented insights into speciation by hybridization. ”
” Papilio Glaucus The group is primarily part of the clades of the subgenos of the New World clades on a large scale Pterourussometimes recognized as a distinct genus,” they added.
“The various within the group demonstrate adaptation to a variety of thermal niches that are warmly characterized (Papilio Glaucus), intermediate (Papilio appalachiansis), and cool (Papilio canadensis) Climate region; all have a wide larval host plant diet and are not limited by its distribution. ”
Papilio Sorstian It is closely related to these three species, but unlike all of the series of characters.
“The most important differences are evident in developmental biology and biology,” the researchers wrote.
“Papilio Sorstian Compared to May for all other species, it is unique during long delays in appearance after adult escape, starting from late June to early July to late June to early July. ”
Papilio Sorstian'The geographical range is Papilio Glaucus The southern end of Papilio canadensis.
“Core Range Papilio Sorstian It includes eastern and south-central Ontario, northern and central New York, and adjacent Vermont, New Hampshire and Pennsylvania.2The scientist wrote in his paper.
“In New York Papilio Sorstian He lives in most of the states except the Southeast and New York City metropolitan areas. ”
“In Canada, Papilio Sorstian It extends westward from Montreal, Quebec, to the Bruce Peninsula in Ontario and south to the Niagara region. ”
“The western limits seem to be on the east coast of Lake Huron. We haven’t seen any verifiable specimens of the west there.”
“Current evidence is consistent with the possibility Papilio Sorstian There is a recombinant evolutionary origin of Papilio appalachiansisThey added.
“However, the evolutionary origin of this kind, Papilio Glaucus-complex, I still can’t answer. ”
“Recognizing and defining the taxonomic identity of this unique evolutionary lineage is our hope to provide a staging point on the fertile grounds for future research.”
