The Australian Tortricini, Schoenotenini, and Chlidanotini together include
40 species in 17 genera. The Tortricini which are represented by 16 species in six genera,
fall into two groups, the Phricanthes group with two genera and the Eboda group with
four genera. Phricanthes Meyr. contains four Australian species, P. peistica and P.
diaphorus being described as new. The other two species have a wide distribution
abroad. The larvae attack plants in the family Dilleniaceae. The endemic genus Scolioplecta
Meyr. includes seven widely scattered species, of which S. exochus and S. allocotus
are described as new. A new species, A. diapella, from the Cape York Peninsula is referred
to Amboyna Razowski, based on an Indonesian species. Anameristes, gen. nov. is a monotypic
genus from north Queensland rain forest, established for Eboda cyclopleura Turn.
Eboda Walk, contains one Australian species, and a series of others in the Indo-
Malayan and Papuan areas. Asterolepis Razowski includes three species from Australia
and New Guinea, with A. earina from Cape York and A. brandti from Papua described
as new.
The Schoenotenini are represented by 19 Australian species in seven genera.
Two elements are distinguished. The Proselena group ranges from India to the New
Hebrides and Rapa, including eastern Australia and New Zealand, while the Schoenotenes
group has reached its greatest diversity in New Guinea. Proselena Meyr, has two
species; Syncratus, gen. nov. has two new species, S. scepanus and S. paroecus; Tracholena,
gen, nov., with type species Cnephasia sulfurosa Meyr., has three species; and
Palaeotoma Meyr. is monotypic. The larvae of Proselena are leaf miners in Bursaria,
those of T. sulfurosa tunnel in the bark of exotic Cupressus, while Palaeotoma has larvae
boring in insect galls on Eucalyptus. Larval characters of these are discussed and compared
with those of the New Zealand Prothelymna and Dipterina. The wide-ranging
Diactenis Meyr., with a single new Australian species D. tryphera, may also belong
to this group. Two genera of the Schoenotenes group are known from Australia.
Cornuticlava Diak. includes three rain forest species in northern Queensland, including
C. aritrana and C. phanera described as new. Epitrichosma Low. contains seven
Australian species, one of which comes from the Darwin area, another E. hesperia,
sp. nov. from south-western Australia, one from rain forest in southern Queensland
and eastern New South Wales, and four including two new species E. ceramina and
E. metreta from north-eastern Queensland. The last also occurs in New Guinea.
The Chlidanotini contain five Australian species in four genera. Trymalitis Meyr.
and Caenognosis Wals. are small but widely distributed Old World genera. The two
new monotypic endemic genera Daulocnema, based on D. epicharis, sp. nov., and
Leurogyia, based on L. peristictum, sp. nov., are described.
The venation, genitalia, mouth-parts, and other adult structures, used to distinguish
the genera, together with the larval characters of a few species, are discussed and figured.
The genitalia of both sexes and the wings of the Australian species are figured and keys
to the genera and species are given.
