Polyorthini
Based on a multi-gene phylogenetic analysis of
Tortricidae,
Regier et al. (2012)
found
Polyorthini
to be the most basal lineage, sister-group to the remainder of the family. According to
Horak (1998)
, the tribe has two centers of distribution (the Neotropical and Oriental-Australian regions) that are linked by related genera in South America and
Australia
, but the tribe also includes two highly divergent genera restricted to the Palearctic.
Horak (1998)
reports that “Rearing records are scarce and feeding modes diverse, including leaf-rolling and boring.”
There are several records of the polyorthine genus
Lopharcha
Diakonoff, 1941
feeding on
Cinnamomum
Schaeff.
(
Meyrick 1918
;
Fletcher 1921
;
Diakonoff 1974
;
Liu and Kawabe 1993
;
Devasahayam and Abulla Koya 1993
) and
Litsea
Lam.
(
Dugdale 1966
;
Sam et al. 2017
) (both
Lauraceae
), and of the genus
Polylopha
Lower, 1901
on various
Lauraceae
and
Annonaceae
(e.g.,
Fletcher 1921
;
Diakonoff 1974
,
1982
) from the Old World. For New World
Polyorthini,
Janzen and Hallwachs (2009)
have reared numerous undetermined and/or undescribed species of
Histura
Razowski, 1981
and
Ardeutica
Meyrick, 1913
on
Nectrandra
and
Ocotea
(Lauraceae)
. Whereas most of these records probably refer to external-feeding larvae, two seed-feeding
Histura
have been reported, one on
Persea
(Lauraceae)
in
Guatemala
(
Brown and Hoddle 2010
) and one on
Beilschmiedia pendula
(Lauraceae)
in
Panama
(
Brown 2019a
).
In contrast to these Lauraceae-feeding genera,
Pseudatteria volcanica
(Butler, 1872)
, a brightly colored, diurnal moth, and
Polythora viridescens
(Meyrick, 1912)
have been reared from at least three species of
Mollinedia
Ruiz & Pav. (Monimiaceae)
in
Costa Rica
and
Brazil
(
Becker 1970
;
Janzen and Hallwachs 2009
), and
Biclonuncaria
Razowski and Becker, 1993
has been reared from
Fabaceae
(
Razowski and Becker 1993
;
Janzen and Hallwachs 2009
). In Europe,
Olindia
Guenée, 1845
has been reared from
Ranunculaceae
,
Saxifragaceae
, and
Euphorbiaceae
(
Disque 1908
;
Bradley et al. 1973
), and
Isotrias
Meyrick, 1895
from
Rosaceae (
Bradley et al. 1973
)
. During the
Ecuador
survey one species of
Polyorthini
was encountered.
