New synonymy
.
Nullana sinchona
has atrial processes (
Figs 56, 57
), which contrasts with the diagnosis of the genus by
DeLong (1976)
. The presence of atrial processes was even acknowledged in the description of the genitalia of
N. sinchona
: "A pair of parameres [atrial processes] arise on dorsobasal portion of shaft [atrium] and extend almost to apex of shaft". Moreover, the illustrations of
N. sinchona
(
Figs 53–57
) are identical to the illustrations of a previously described species,
Ponana (Lataponana) cephalata
DeLong, 1977
(
Figs 44–48
). The descriptions of the coloration of both species are identical: Head and thorax brownish yellow. Pronotum with black spot behind each eye. Forewing with four black spots, two on cross veins of discal cell and two on apex of anal veins. Both are from the same locality, Sinchono,
Peru
(
Figs 43, 52
). According
DeLong, (1977)
the
holotype
of
N. sinchona
is labeled "
Sinchona
,
Peru
,
XI-1943
, J.G. Sanders coll." and according
DeLong and Martinson (1980)
the
holotype
of
P. (L.) cephalata
is labeled "
Sinchona
,
Peru
,
November 1943
, J.G. Sanders coll.". Based on examination of photographs of the
holotypes
of both species (
Figs 40–43, 49–52
), deposited in the C. A. Triplehorn Insect Collection (OSUC), and study of ten male specimens of
P. (L.) cephalata
, deposited at DZUP, from
Peru
,
Cuzco
, which we compared with the descriptions, illustrations and images of both species, we are confident that both are the same species and that they are now correctly placed in
Ponana
by
Delong (1977)
.
