status

 

Chlosyne bollii (W. H. Edwards, 1878) is a species distinct from Chlosyne theona (Ménétriés, 1855)

Our previous genomic analysis demonstrated that Chlosyne chinatiensis (Tinkham, 1944) ( type locality in USA: Texas, Presidio Co.) is a species distinct from Chlosyne theona (Ménétriés, 1855) ( type locality in Nicaragua) (Zhang et al. 2020) in agreement with Cassie et al.(2001). Sequencing of additional specimens across the range from Arizona and Texas to Costa Rica reveals that Melitaea bollii W. H. Edwards, 1877 ( type locality USA: Texas, Bexar Co., San Antonio), currently regarded as a subspecies of C. theona (Fig. the mitochondrial genome tree (with some possible introgression, Fig. 9c) (i.e., not monophyletic with Chlosyne theona ), but is sister to C. theona in the Z chromosome tree ( Fig. 9b). All other subspecies of C. theona we sequenced (including a nominotypical specimen from Nicaragua, NVG-22097C09) clustered together and were not strongly separated from each other despite large geographic distances between these populations, e.g., Chlosyne theona thekla (W. H. Edwards, 1870) ( type locality in USA: AZ, Pima co.) and Chlosyne theona costaricensis (Austin & M. Smith, 1998) ( type locality in Costa Rica), and their phenotypic distinction. The genetic differentiation of C. theona bollii from C. chinatiensis and all other sequenced C. theona subspecies is at the level characteristic of distinct species, i.e., Fst / Gmin /COI barcode difference of 0.62/0.001/0.6% (4 bp, they essentially share mitochondrial DNA) ( C. chinatiensis ) and 0.46/0.003/1.2% (8 bp) ( C. theona ). Therefore, we propose that Chlosyne bollii (W. H. Edwards, 1878) , stat. rest. is a species distinct from Chlosyne theona (Ménétriés, 1855) .

A natural hybrid between Chlosyne bollii (W. H. Edwards, [1878]) and Chlosyne chinatiensis (Tinkham, 1944)

Sequencing of a suspected hybrid between Chlosyne bollii (W.

H. Edwards, [1878]), stat. rest. ( type locality USA: Texas,

Bexar Co., San Antonio) and Chlosyne chinatiensis (Tinkham,

1944) ( type locality in USA: Texas, Presidio Co.), a female

NVG-19072B01 collected in USA: Texas, Brewster Co., along

FM2627 25 mi SE of USH385 on 23-Mar-1994 by Steve M .

Spomer ( Fig. 10) places it in different positions in the three trees

( Fig. 9 olive) thus confirming its hybrid origin. In the nuclear genome tree constructed from autosomes ( Fig. 9a), this specimen is sister to C. chinatiensis , suggesting that it has a significant fraction of C. chinatiensis genes. In the Z

chromosome tree ( Fig. 9b), this specimen is within C. bollii ,

suggesting that its Z chromosome, which in females is inherited from the father (in butterflies, ZZ are males and ZW are females), came from C. bollii . In the mitochondrial genome tree

( Fig. 9c), the specimen is placed within C. chinatiensis ,

suggesting that its mitochondrial DNA, which is inherited from the mother, came from C. chinatiensis . Therefore, we confirm this female as a natural interspecies hybrid and conclude that its father was C. bollii , and its mother was C. chinatiensis .
