Definition and diagnosis.
Genomic analysis reveals that
Heliopetes arsalte
(
Linnaeus,1758
)
(type locality “Indiis”,
Honey and Scoble (2001)
suggested “South America, probably the Guianas”) is not monophyletic in both nuclear and mitochondrial genome trees (
Fig 39
blue and red), and instead northern populations identified as
H. arsalte
(
Fig 39
red) are sister to
Heliopetes marginata
Hayward, 1940
(type locality
Ecuador
: Balzapamba) (
Fig 39
green). The three clades are well-differentiated genetically:
Fst
/
Gmin
statistics for their comparison are 0.39/0.007, and therefore represent three distinct species. Searching for possible names that may apply to the northern populations (red clade), we see that
Pyrgus figara
Butler, 1870
was not definitively assigned to a particular locality.
Butler (1870)
wrote about the species he described in the publication that proposed the name
figara
: “The greater part of these are in the Kaden collection, now in the possession of Mr. Herbert Druce; and many of the species are from
Venezuela
.” Indeed a
syntype
of
Pyrgus figara
Butler, 1870
, female in BMNH, is labeled from “Druce Coll. ex Kaden Coll.”, and although it lacks the locality label, it is consistent with phenotype of
H. arsalte
from
Venezuela
(or other South American countries) in that it is a dark specimen with heavy overscaling along hindwing veins, especially by the outer margin, and broader dark marginal border on forewing (covering distal third of the wing) than in any North American specimens we have seen. Forewing costal cell is completely brown, and in North American specimens it is either mostly white and if brown then with a white streak at the base and along costa (
Fig. 40
,
41b, c
). Therefore, this evidence suggests that
P. figara
is of South American, possibly Venezuelan, origin, and this name does not apply to the red clade (
Fig. 39
), indeed being a synonym of
H. arsalte
. In the absence of other available name candidates (
Papilio niveus
Cramer, 1775
is from
Suriname
and is quite similar to South American
H. arsalte
, both having very narrow dark borders on wings, typical for males from the Guianas), the red clade represents a new species. Curiously, the COI barcodes are 1.7% (11 bp) different between the new species and
H. arsalte
, despite not being monophyletic with it, but 2.1% (14 bp) different from its sister
H. marginata
. This is because the evolutionary rate in the mitogenome is slower in
H. arsalte
(
Fig. 39b
blue) compared to the other two species (
Fig. 39b
red and green). The new species keys to C.2.7(a) in
Evans (1953)
and differs from
H. arsalte
by male genitalia (
Fig. 42
): the tegumen is longer, bulkier; the valva is narrower, the harpe is straighter, separated from the ampulla by a wide cleft, the phallobase is shorter; and by the dark form females (
Fig. 41c, d
) with narrower forewing dark border, especially towards tornus, and more extensive pale scales (sometimes a ray) in the forewing costal cell towards the wing base. Due to phenotypic differences being slight, best diagnosed by DNA. A combination of the following base pairs is diagnostic in nuclear genome: aly3766.1.5:G62C, aly
2379.11.15
:G51A, aly16576.4.4:C143T, and aly274.30.2:T84C, and COI barcode: A160G, A181T, C367C(not T), T562A, and C610T.

Etymology.
The name is inspired by the
type
locality. Boca Chica is now a site for SpaceX, a company founded by Elon Musk that opens unprecedented opportunities for the exploration of the unknown. It is our hope that nature of the Boca Chica area will be preserved, and genetically unique species like this one will thrive there and around the area. The name is a noun in the genitive case.
English name.
SpaceX white-skipper.
