DISCUSSION
: As
Hering (1925)
noted,
L. ena
is perhaps the most common species of
Josiini
in collections. The taxon is widespread, occurring from
Panama
south to
Brazil
and
Peru
, and is one of only three josiines found on
Trinidad
. Based on genital similarities,
L. ena
belongs in a subclade of the
Angulosa
Group along with
L. ariaca
,
L. banana
, and
L. enoides
. All of these are separable by their wing patterns (pl. 29).
However,
Lyces ena
(pl. 29) and
Proutiella infans
(pl. 26) are essentially indistinguishable, sharing nearly identical wing pattern, body coloration, and size. Both show variation in the width and shape of the yellow transverse FW band. It has long been assumed by curators at collections around the world that all josiines of this size and appearance represent a single species—
L. ena
. Not until
August 2005
, when the
type
of
infans
was studied, did it become clear to me that two species were actually involved. Upon closer inspection, wing venation and abdominal coloration provide easy means for separation. As is true of other
Lyces
species
(fig. 320I), FW vein M
1
in
L. ena
arises from the DC, almost touching—but separate from—the base of the radial sector; the abdominal venter is completely white or whitish gray; the thoracic scales are short, but they are not ovoid and appressed. In
Proutiella infans
, on the other hand, M
1
is stalked with Rs
1
–Rs
4
, arising basal to Rs
1
(see fig. 284C); the abdominal venter is white with a wide gray stripe along the midline; and the thoracic scales are extremely short, ovoid, and appressed.
Lyces ena
has been recorded from two
Passiflora
species
(table 6): in
French Guiana
, caterpillars were found on
Passiflora laurifolia
, whereas in
Panama
they feed on
P. vitifolia
. These plants belong in different
Passiflora
subgenera according to
Killip (1938)
.
The
type
of
tryma
Schaus
shows identical characteristics, including male genital morphology (JSM-1533), with those of
L. ena
, thus confirming
Prout’s (1918)
synonymy.
